Diesel gurus, please help diagnose my 1HD-T

[BCR4619]

In that case, screw it!


My dads truck was a clean burning one, little puffs of blue now that its getting up there in age but turbo is original as well as the breather routing but that has now caused oil to coat all the intake pipes n manifolds on the outside and once u mix that with dirt it gets messy quick!.... This on one of the reasons I deleted my stock routing of the breather.

Andrew,

do you fill up at the shell station at the bottom of the hill by royal roads and the 9 mile pub or whatever?
When I was going to school down there, I tried out the V-power a few times. I honestly noticed no difference though I didn't pay attention to if my truck smoked more on it.

I think regardless if you run good quality normal diesel and add your own additive your probably better off. I hear plenty of stories of "premium fuel" which comes from the same regular fuel storage tank.

I would try switching fueling stations. Flying J is the same as Shell in the states isn't it. I have heard of guys having issues with their diesel being lower quality in comparison to other brands.

No, across the highway from Spenser Rd (heading out of town towards the Malahat). The odd thing though is that the truck seemed to REALLY LIKE the Shell diesel from Merritt.

Sometimes I wonder why I care so much, I seem to go through these phases of I gotta deal with this and then you post some findings which I follow and I am about to do myself and wham you get back to the island and it starts up again lol

I cant remember but if you throw her in neutral does it stop? I know if I am at a light I can see this haze pass by my window and once I throw it in neutral it clears up a few seconds later but it will return once I put it into D and drive off. I try to get my truck up to 90-100km/h as much as I can which ends up to be 30 min on saturday or sunday and the rest is city driving...

Heh, I know what you mean. It's like chasing a leprechaun to the end of a f*king shiny rainbow. I have a lead on a job in Kamloops, I may be moving. So perhaps the crappy diesel on the island won't be a problem?

It does exactly that.

Is there a chance this is just the way they run? Every 1HD-t I have seen run is smokie, some are a lot worse than yours.

Perhaps they are prone to do that. But I cannot see these high end rigs smoking on the Toyota showroom floor like that, even in 1993.

Not only that, but I don't believe in coincidences... at least not like this. It burned clean as a whistle for the ENTIRE tank of fuel I purchased in Merritt at Shell, and same for the tank I purchased from Husky in Williams Lake. Even once I returned here to the island for 3 days you could not even get a glance of smoke. (ruling out elevation, temperatures, etc) An hour after I fill up the tank here in Victoria, and it all went to s***? No way that's a coincidence.

 

[pHarps]

Have you had any changes in smoke over this winter?

 

[ForealBoreal]

Not to be cocky or anything but there is an Allen bolt at the very top of your boost comp that is called the smoke screw. It's designed to change your idling fueling as it does minute changes. I would try it out... I can explain how to if you like.

Not at all, no worries. I know about the idle compensator and have read the documentation and tried adjusting it myself, with no change to the smoke. I tried in 1/4 turns all the way to a full turn in either direction. Should it need more than that? FWIW the yellow factory "set" paint was still in place (it hadn't been adjusted before)

None while on the island. Like I mentioned, the 2 tanks of fuel I purchased in the interior burned COMPLETELY clean. Then when I refueled on Vancouver Island again (even with the same brand/grade) it went completely back to the way it always was. I haven't been investigating anything else in the last while since I am moving to Kamloops at the end of the month, and will see how the fuel there burns.

Just to recap... play them both at the same time to reeeeally see the difference...

EDIT: SEE POST NEAR BOTTOM OF THE PAGE REGARDING D1 and D2 DIESEL FUEL GRADES

D1 diesel fuel, sold in Merritt during the winter months


D2 diesel fuel, sold in Langford (Spencer Rd)

Im inclined to wonder if someone is adding a less than ideal additive to their diesel tanks. A fuel analysis would be interesting.

Like water? HAH! I agree.

It's worth to note (for those not familiar with these cities) that Merritt and Williams Lake (the two cities where I received the really clean burning fuel) are both sub-zero C cities in the winter, where-as Vancouver Island is not.

I know for a fact the cities that are colder in the winter (like Merritt) all the gas stations add an anti-gel additive to their diesel, but on the lower mainland and Vancouver Island I don't believe they do.

I'll report back after I get to Kamloops and go through a tank or two of fuel. I'm leaving on Feb 28th.

 

[sailor]

Mine is smoky or not, depending on its mood etc. The only way to reliably reduce the smoke is to take it on a road trip and get it good and hot over a prolonged period. The smoke is apparently just the nature of the beast..

 

[themorb]

Wow those videos are worth keeping. My smoke disappeared when I filled up at the Hope Esso after Christmas. Came back when I filled up at the Co-op on the island again.

Maybe you can get a hold of some anti-gel additive in Kamloops and ship it down here

 

[asutherland]

While I agree a long, hard drive is definitely a contributor to reducing the smoke, I'd disagree it's the only factor here. I drove around Victoria (short, city driving) for a full week on the same tank of fuel I purchased in Merritt, and did not smoke one little bit. Both videos above are in my driveway here in Victoria.

Then I filled up in Victoria, on about 1/8 tank left, and within a couple hours of driving it went from NO smoke to SOME smoke (about half as bad as it usually did) and then within a couple 100 KM it was back to being terrible.

 

[sailor]

Yeah, I must say that over 90K of driving, the cause of the smoke has eluded me. Sometimes good, bad no rhyme or reason. Truck runs very well, never had an issue otherwise.

 

[SHREDwagon]

She was smoking pretty bad before rebuilding the injectors and pump......All was well for the first few days after...then the smoke re-appeared. Changed the fuel filter with an OEM one and it was fine again. 2 days later it returned.

Now it comes and goes like you vid. Warm or cold. Using Stanadyne in every tank.

When I changed the fuel filter, I drained the diesel from the bottom into a zip-lock bag. Under light I could see what looked like white pellets about an 1/8" dia. Assuming it's water that reacted with the Stanydyne.

I don't know if this helps, but you could try draining your filter and see if your getting the same. That would confirm if it's the diesel.

Other than to install a secondary filter and talk with Raj, I'm out of ideas.

 

[asutherland]

Update...

I have been living in Kamloops for 1 week now. I've put a whole tank of Kamloops diesel through the truck, and am now 100km into my 2nd tank. I have made NO changes at all. The Cruiser has stopped smoking.

Small puffs of black if I am punching it up a hill, and a little bit of smoke on completely cold startup (that seems to last about 2 mins of driving). I will let you know if that changes for the better over this next tank. No idle smoke at all, even in drive. No haze following me down the road. I am what you call a Happy Camper!

 

[BCR4619]

Send a tanker our way boss!

 

[asutherland]

It'll be interesting to see how the "summer fuel" or regular fuel affects it. I wonder when they stop selling (or adding to?) the winter fuel? If we could determine exactly what they put in the fuel, we could add it to our own tanks and be smoke free year 'round... including you unlucky coastal dwellers

By the way, did I tell you how beautiful and sunny and warm it was all weekend?
