Good luck with the oil pump gear. I think you'll be fine. I wouldn't bother with positive valve seals though. Umbrellas do a fine job.

When positive intake valve seals work as they should, they offer a measureable reduction of oil injestion into the intake tract. That will result in a cleaner combustion chamber. In a race or limited use motor that does not get a lot of use that may not make much difference. But the 83 D150 is a 6 month a year daily driver, it gets used, nearly 50,000 miles so far, more to come.
Umbrellas have been around for a long time to, I did put those on the exhaust valves.
I got the seals from a internet seller named Alex's Parts. Wide selection of valve seals, fast shipping, cheaper than Summit.

The engine is about buttoned up, oil pan on the bottom and the cylinder head back on top.
I posted a photo of the windage tray that I had made for the slant in the D150 when I re did the engine nearly 10 years ago. It has held up fine.
The front of the truck oil pan is tucked in really tight to the #1 rod cap, and then it slopes back gradually to the sump. That is why I started the windage tray after the #1 rod cap. Even the #2 and the #3 caps don't have a bunch of room between them and the pan, that is why I opened the forward drain windows so much, I wanted to made sure the oil flung off the rod got to the back side of the windage tray.
Also posted photos of the NOS Mopar hydraulic lifters, part number P4095897, per the box 1988 vintage, set in to match up with the NOS Mopar cam.

That sure is a goofy Looking windage Tray, But of course I am sure it works great.

Rarely do you see anyone futzing with one in a truck pan.

You'll be back to showing up Wayne and all the other slanters in indy soon!

well,, that tray fits in the truck pan, which for some one making a one off slant powered race vehicle, if it would fit, I think the rear sump truck pan would be the way to go.
the deep rear sump, would minimize oil sloshing away from the pick up, the rear ward slope of the front section of the pan would move oil to the sump.

There have been a couple of postings at FABO mentioning Rustoleum Ultra High Temp paint being used on headers and manifolds with success.
I gave it a try on the dual Dutra's on the 83 D150. These have been powder coated twice by Indy Powder Coat, with much less than satisfactory results.
The color faded and discolored in about a seasons worth of use.

This Rustoleum Ultra paint went on very smooth and has a high luster. I baked the manifolds in an oven for an hour at 450 as recommended. Will see how this product lasts.

Other good news is the motor is ready to go back in chassis.

Looks nice to me either! Rustoleum stuff is also highly used around here.

What kind of prep do you need for the hi-temp rustoleum?
Author:  DadTruck [ Tue Apr 27, 2021 5:58 am ]
Post subject:  Re: 83 D-150 Project
Nothing special for surface prep. Clean, dry, no existing flaky paint. I washed the Dutra's in hot water and Dawn dish soap, then went over them with the power washer.

Full details on that heat resistant paint are below:

I sometimes use the kitchen oven for baking stuff.. usually car parts.. not food.

I have had exhaust parts powder coated before as well with less than good results. Hope this works better for ya!

Yes, used the kitchen oven. The product info mentions that there is are non-toxic fumes, which there were. Was a nice day here in Indy so we had the windows open and it dissipated quickly.

I dunno that I'd admit that on an open forum..... never know, the wife might be lurking.....
I have heard that for the home powdercoating stuff that an electric oven is better for such a job vs a gas oven. I have read that for those wanting to try this at home to find a cheap used oven in the classifieds or CL, etc......

back on the real reason I needed to pull the motor in the D150,, increasingly difficult to shift, clutch engagement issues.

the first photo below is the new pressure plate that is going in, as recommended by Josh, I have put a touch of a spot weld on each of the adjusting bolts.
The other two photos are of the adjusting bolts on the pressure plate that is being removed. With that pressure plate bolted up to the flywheel there is nearly 1/4 inch height difference between the three clutch plate fingers where they would touch on the TOB. A closer look at the adjusting bolts, shows that the staking that was to hold the adjusting bolts in place was too light to be effective. The stake mark did not intersect into the threads of the bolt.
That pressure plate was likely properly adjusted when it was installed. Over time with use the adjusting bolts and fingers moved. I do plan to take this PP back to the seller (NAPA), it is past the warranty period, but also is an obvious example of a manufacturing defect. I have experience pushing rope up a ladder, I will see where this goes.

John, what is the brand / manufacturer of the New PP that you are placing in service? Looks slightly Different Thant the typical Borg & Beck 10" Unit if I remember correctly...
