All cummins are this way. I just sold my 24V and it would take a solid 10 mins of driving before the warmth started to build, and another 5-10 mins beyond that to really get cooking. Cold North East winter mornings are always a little bit painful...the drive to the train station is over before the heat kicks in properly.
 
Got the truck back on the road today for a drive. I started by pressureizing the cooling system for 4 hours at 20psi. It did not drop at all over the 4 hours.

Got a few more thing done inside while I waited. OIL pressure warning buzzer and LED mounted, ashtray removed and turned into a power point with two 12v constant outlets.

Can't find any placed I like now to mount the gauges. I actually really like not having any at the moment I know the EGT''s are cool and the boost is low so no real need for them at the moment. I was eyeing a glowshift 3 in 1 with EGT, boost and fuel pressure. Makes it a bit easier having to find a spot for one gauge and not 3. Not sure yet what way I'll go.

Took the truck for a 30 min drive on some country roads. Was about 22c out and the warmest the coolant got was 162f no visable leaks and no sweet coolant smell. Tomorrow I plan to drive it a binch more and see how she does.
 
100kms of driving today and no signs of leaking water. Temp was/is 26c engine temp peaked at 173f after a hill in 5th at 110kms/hr. It's quite a feeling not heeding to do anything to maintain speed up hills on the hwy now just a slight press of the accelerater and away you go.

Will post some more stuff later tonight still on the road.
 
Good to hear! I was betting your "problem" would cease with some mix.

Have you pulled the freeze test on it yet? I'd certainly hate to see an early freeze this fall in your neck of the woods and push the freeze plugs out, you've come WAY to far for that to happen!

I have a feeling my "problem" may have been a big of hyper sensativity. I have a feeling the HG never leaked and it was actually risidual diesel from the last time I had the injection lines off for a re torque. The fuel runs down the side of the block right where the clean spots are. Time will tell I guess.

No worries with temp's cold enough here to pop freeze plugs. We 3-4 below freezing days a year here. The coolant is a 50/50 mix tested at -32c.
 
Good to hear! Do you feel comfortable enough now to put some road trip miles on it and get some MPG estimates for me?! My 12 is killing me, looking at a diesel VW pickup to DD for now and use when I'm doing my swap.

I'm likely going to take Monday off and head out tomorrow on a road trip. Nothing too long but anough to camp over night and use a couple tanks of fuel.

The first full tank I ran through it lasted longer than any other tank 610km and it only took 74L to fill. Worked out to about 19.5mpg. That was about 70% hwy but I did have my RTT and a rack on the hole time.

I need to get a few tanks under it before I know what it gets average. First tank around town all city and short driving trips was 17.8mpg.

Much better than the old gas engine and I actually have power to effortlessly drive anywhere.
 
Ok so I spent the morning getting a few thing's checked off the list.

First on the list was drop the cross member and paint. When I dropped it I found my vibration that I was getting under load.



Massaged with a 3lb sledge before paint.



Next project on the list was get my ARB drawer and fridge back in.



Then contemplate where and how I'm going to get this mounted.



20lb co2.

I was not able to get my engine driven York on the cummins so I needed an alterative. It's not idea but it's better than not having Air.

Test drives today went great, no issues noted. No external coolant leaks. So much better driving now that that crossmember contact is removed, quieter under load and even normal driving. Amazing how such a small spot can make such a difference.

Tomorrow is going to be a big day, I'm taking the truck on a solo fairly long 700km road trip/ overnight camp. Trip will have a bit of dirt but I'm going to limit that for now till I know it's all good.

Wish me luck!
 
Was your xfer case tapping the cross member?

Yes, it appears to be about 1/4" lower. I may try spacing the mount up when I have time becouse my cruising off road skid does not fit now too. I'm going to have to be careful though with the shifters/tunnel clearance.
 
Hey Jeremy, I have a nice Powertank Supertank bracket I'll give you a good deal on, if it fits the 20 lb bottle - I bought it for a 10 lber. Never been used.

Glad to see the truck FINALLY seems to be working for you! What a freakin' ordeal.
Are you bringing it out to Cruiser Day?

That would be great! Hopefully it fits, I was looking at making one but decided my time is better spent using the truck not building stuff for it.

I'm very happy as well, my fingers and toes are still crossed and there is a lot of "knocks on wood" still but I'm building trust in it slowly.

I will not be at cruiser days as I have a prior trip planed to do Whipsaw. I will be at the 4wdabc show next weekend though.
 
Cool - I'm 50/50 whether I'll make the 4wdabc show - trying to make the next CC meeting next thursday though. (I think the last one I was at was when I talked to you about beginning the 4BD1-T swap!)
Otherwise you can pm me and check it out if you have to come through North Van some time. If it doesn't fit I can give you a deal on a 10 lb'er with regulator too - also never used :grinpimp:

That's funny I went to my first CC meet last month since the one we talked about my isuzu swap. Hopefully see you there, if not well meet up another time.
 
Well on Saturday night I decided it was time to stop worrying and start enjoying. My wife and son are out of town visiting family in Winnepeg so it was the perfect opertunitie for myself and my dog (Fran) to head out. I love camping with my wife and son but would not do a last min solo trip with them at this stage. I sent off a quick e-mail to work and let them know I was taking a vacation day Monday.

Sunday AM I had a short list of things to get before heading off. I pulled out of town and started driving towards Whistler at about 11:30. Traffic was light and it was nice to have a relaxing drive through the city (Vancouver lays between myself and Whistler). Got on the hwy and smiled at myself as I drove along, cummins humming in the back ground and Tom Cochran "life is a highway" playing on the sterio.

I got through Vancouver and started up the Sea to Sky highway that links Vancouver and Whistler. It's now a almost entire 4 lane highway, nothing like it was pre Olympic winter games. Use to love driving my fast cars on the old highway as it twisted and turned rose and sank. Now as I am Older and driving a 7k lbs truck along I can appriceate the improvements. It's still a spectacular drive and I encurage all visitors to do it.

As pulled into Squamish I stopped for fuel (13.9L/100kms last tank) and the last of my supplies. Gave the truck a quick once over and dog some water and headed off. I did have a young Australian man come up at the gas station and want to know all about the truck. He has a Sahara back in Oz and wanted to know what was done to mine. I guess him and his parents are up here for the summer touring around Canada in a rented pick up and trailer. I gave him a quick run down of the truck and after I picked his jaw up off the ground I was off again. The flow of tourist leaving Whistler back to Vancouver or where ever home is was huge, thousands of cars in a constant stream. I was lucky going the oposite way and had very light traffic.

Whistler is not my final destination I'm actually just driving right though. I stopped in the town of Pemberton next and grabbed 2 bundles of fire wood (chainsaw is dead) and a quick bite to eat. There was a lot of people in their early 20's all over town looking like they had been run over my trains, supper hang overs as the Canada day long weekend wound down. Took Fran (dog)for a quick walk to stretch her legs and off we went. From Pemberton there are a few choices, the Duffy lake road (tarmac), Hurley (gravel), D'Arcy to Seton Portage via a gravel upper shelf road (my choice this trip). I had been on this road about 5 years ago and views as you get up 2000ft over a emerald green blue lake are breathtaking. So is the single lane no guardrail shelf road.

Truck was running flawlessly as we turned off the tarmac onto gravel to start the shelf road. Temps where solid 168-173f depending on the load. Engine was purring along with out a care in the world. I let the tires down from 43psi down to 25psi to give me a slightly smoother ride over the rarely maintained shelf road. 3rd gear seemed like the right one for a comfortable speed (40-45kms/hr) and power. A few of the short switch backs I was down to 2nd as you almost come to a stop to make the turn. Temps still solid 168-175f ambiant air temp was 28c (85ish f). On some of the steeper sections the temp would get up to 175 and then come right back down as soon as I crested the hill.








We made good time and got to Seton Portage about 5pm. This little town is I belive a native reserve and has a huge hydro electric plant.

These pipes are about 12ft diameter each.


Road right through the power plant...


As soon as you come through the power plant you turn sharp left and start up the mountain. This road is one of the steeper I have driven in BC it's 8kms of 14% average grade and it's a dirt road. It takes you up and over a mountain to carpenter lake. It's quite a climb, I remember doing it in my truck with the 1fz and really having to push it to get up some of the switch back. This time it was a breeze again mostly 3rd some 4th and a couple hills in 2nd. I was not in a rush so just took my time.
 
This is a great hill to test a cooling system! On the top two switch backs my temp got up to 185 rather fast and I started keeping an eye on it. As that happens I heard a slowly growing roring howl, I actually thought it was a big rig with its fan locked it was so loud.......nope that was my fan engaging. It was freaking amazing! Foot to the floor in 3rd up a steep grade and the temp dropped from 185f to 168f when the fan disengaged. It was quite a suprised and very welcome one. It did it once more on the last hill as I crested with a big smile. I have got zero cooling issues!

Now I get to go back down the other side of the mountain 14% grade for 4 kms. I stuck the truck in 2nd and just let the engine control speed at about 25-30kms/hr. I'm not in a rush and loaded like this I can feel the brakes strain to stop this thing. So slow and steady.

I got down to carpenter lake, it's man made and has a large earth dam at the end. It's cool becouse you get to drive through a tunnel then straight out onto the bridge over the spill way.



As you turn towards Lillooet there is a small BC hydro or forestry recreation site. These are camp grounds set up in the 70's and 80' if I'm not mistaken for residence to go camp in non maintained remote areas for free. This one has 3 spots in a little corner shielded from the ever present winds coming down the valley. Here we picked a spot and set up camp, got the ARB rtt all setup and small fire going to cook dinner.







I stopped at my local specialty Butchers and picked up a 23oz rib eye steak for dinner. It's the most expensive non cooked steak I have ever bought and I planed to cook it over a camp fire ;). Got the fire going to the steak on soon after. As the steak was sizzling away I got the $1.49 instant mash potatoes going, it's like ying and yang lol. The steak was soon flipped for another 5min and then off into tin foil for 5 min to rest. When I cut into it.....perfection med rare and my god was it bloody good. The fat rendered on the fire into this crispy smoke candy fat and all I could think about was.....yep that was worth it!








View from camp


Next morning


Breakfast.



Spent the rest of the evining at the camp fire letting all the stress of the last year just slide away. Having a baby has been by far the best experience of my life but as all parents know it comes along with new stress and worry. I topped that off with all the issues with the Isuzu.

Sunday we started early about 5:30 am. I made a breakfast of bacon and blueberry pankaes, marveled at the fresh bear prints in my camp site from the night.....did not hear a thing lol.

Got the dishes done camp packed up a nice 45min hike with dog done and we where on the road by 7:30. We drove east towards Lillooet and small community on the Fraser river.

Before town there was a turn off to a road that always intrested me on the map the West Pavilion FSR. This road will take you about 180kms north where it joins a Web of other roads all through the centre of BC. One turn off about 100kms up takes to Big Bar Ferry a current action ferry (no engine) just tell power of the water to move it and your car across the Fraser. I had been wanting to try it out for years. So what better time. We headed down the fairly well maintained road that twists it's way from 500ft elv to 4000ft and back down. The road from the west Pavilion is the Big Bar ferry Rd. It goes from 2500 ft to 800ft in about 2kms.......very steep in some sections to the point I would not be comfortable doing it in the wet.



I got the ferry and turned off the truck to wait. The opproator on the other side sailed across to puck me up. I was his second customer of the day it would turn out....it was 11:30 am by this
