Do you have an HX35? If not, I have my HX35 that was rebuilt by mumau diesel along with my motor. I maybe getting a custom turbo from engineered diesel.
I have my blown one and access to a PDR hx35. Pm what you want for yours.
 
Well today I actually felt like I was moving the right way. I got the pump all cleaned up and painted. New O ring on the front to seal the timing cover and pump. New fuel line seals and other bits.

I also painted the side of the block and side of head that never seems to get any from the factory. Replaced the seals on the lift pump and the pre filter. Eliminated the fuel heater since it was non functional. Think I covered that already but post it again.

Couple poor quality pictures, I have to say this Cummins paint is kick ass. Goes on nice and smooth and is dry enough to work with in 30min.



Never re time or take the pump gear off with out getting a new lock washer.



New lock washer installed but not torqued.



Ready to torque when I have the snap on parts to change the timing. I have it pin timed for now.

I also got a few other parts painted and have a whole pile to do still.

All I need to do on this side of the engine is get the vacume pump rebuilt and mod the power steering pump for more flow and pressure.

I totally agree on the cummins paint, I have been using it to paint my NV4500.

Are you planning on running toyota brakes or going to a hydroboost setup?

Toyota brakes, see no need to go to the hydro boost. Extra complexity and modification.

Do you think there will be enough vacuum being pulled to operate the booster? I would love to avoid figuring out hydro if there is enough vacuum.
 
The newer cummins all run hydro, they gave up the vacuum pump after the 6BT. I haven't been able to find the required InHg for the toyota booster yet. Hopefully it is less than what the pump will pull.
 
I would not think you will have any issues with the factory vacume pump and booster on our trucks. My little vacume pump on my isuzu alternator was enough to make my brakes feel stock. Hydro boost on our trucks would just make things far more complicated than nessisary.
 
Got my vacume pump reseal kit from Cummins tonight. Plan to break it down and get it taken care of this weekend.
 
With the engine out I bet it takes you 30 minutes tops to rebuild the pump.
 
Had a lot I wanted to get done this weekend but came down with a bad cold that my 8 month old also got. Needless to say no work getting done this weekend on the engine.
 
You do a pretty good job of finding garage time for a fella with an 8 month old. My little guy is about to turn 1, and garage time is getting elusive. What's your secret?

Yeah I have done OK. Secret is a very understanding wife. I'm lucky she gives me a one day a weekend to work on it so that's good. I'm also able to tinker after work sometimes if he goes down early. I would get a lot more done if the shop was at my place but it's about 10min away.
 
Had a couple hours today to work on the engine. I got the new oil pan scuffed and painted in the Cummins engine paint. Rear main is installed in the seal housing ready to bolt back on when I'm ready to put the pan back on. Hopefully that will happen tomorrow.

I started looking at the turbo side of the engine. My father suggested removing the exhaust manifold to ceramic coat it and clean it properly. So I did, all the bolts broke free easy and it came off with no issue. One of the exhaust gaskets looked good and done.



Not sure what is going on there. Not worried plan to get new ones. Exhaust valves all look good, one looks slightly oily. So I plan to replace all the valve seals when I do the valve springs.

I got both the exhaust manifold and turbine housing ceramic coated today. It's not as good as paying $400 but the material cost me $60 and $30 for a syphon sprayer. Seems to last OK as long as you don't put it on too thick. I'll get some pictures tomorrow when it is dried. Tomorrow the plan is to install the rear main, oil pan and timing cover. I was going to adjust timing but I'm a bit worried about doing it. I guess this 215hp pump is a bitch to change timing on. We'll see, had wanted to advance it to 15deg.
 
Today I got the rear main on and the new oil pan installed. I wanted to get the timing cover on as well, that is where everything went pear shaped.

That damn crank seal is a bitch to install. I have likely ruined a $70 seal. So frustrating, I have never had such problems.

I did pick up 12 pacbrake valve springs and the pacbrake Governor spring kit today. Got a smoking deal on them so hard to say no ;).

Before I put the pan back on I took a good look around. If I did not know this engine had 200k kms on it I would say it looks new. I'm absolutely blown away how clean the inside of this engine is. I also turned it over all the cylinders looking from the bottom up look great no scoring or wear at all.

This week I hope to get this damn front crank seal taken care of and the cover back on.
