I've lost track of how many changes this think has had, but it's time to get it on the road again!
The previous thread is here => http://www.turbo-mopar.com/forums/sh...rbo&highlight=
Though I think a lot of the pictures got mangled from Photobucket.
Here’s a link to the album if you care to take a look.

Well, I stopped driving the van due to it smoking pretty badly. I was pretty sure it was a valve guide or a valve stem seal issue. Then I decided to take it out for a spin and ended up over-spooling the turbo. Now’s as good of a time as any to replace the head and turbo.
Sad dusty van
I don’t think the shaft of the turbo is supposed to come out that direction.
Bleh! I got a lot of miles out of the free, home rebuilt, and not balanced turbo.
Yeah, I think it’s bad.
The manifold had a nice big crack.
Looks like I’m going to need a new EGT probe.
Turns out the previous machine shop had installed all of valve guides too low to the point where the valve stem seals had nothing to grab on to. I knew something looked fishy from the start, it should have never been installed. Here you can see the exhaust port on cylinder 3 was puking oil pretty well.
This should do nicely!
It’s a journal bearing t3/t4b with a 46 trim compressor wheel and F1-54 turbine wheel with the .63a/r turbine housing and a 2.5” swing valve. Thanks to Cindy @ FWD!
Got the replacement head back from the machine shop (a different one this time). I didn’t go too crazy with the port work. It’s mostly just matching.
Cleaned up a new manifold and port matched it to the turbine housing. Mike Holler’s article on Allpar had some good information. http://www.allpar.com/fix/holler/exhaust-porting.html
Drilled it for a new EGT probe and replaced the studs I broke. I couldn’t find a decent price on the 10mm X 1.5 studs anywhere so I just bought a 1M piece of grade 8.8 all thread from Amazon for $8 with free shipping and cut it up.

It has sadly taken months to get to this point.
I used the Dorman 03411 exhaust manifold stud and nut kit and it worked great.
Hopefully it will run again this Saturday!
