CAS... not bolting down?

[Talesin]

1990 Eclipse GSX

Hey all. My shortblock was replaced just before I picked up the car, and I've had no end to leaking problems, mostly around the CAS. Took it back and they said that they put on the wrong O-ring, and filled it in with silicone sealant.

I've just noticed today that the rear bolt/stud (firewall side) doesn't have enough thread on it to snug the crown nut down and secure the CAS in place. It literally has between 1/4" and 1/2" of play. The front bolt is snugged down firm, but I'm still losing oil (they claimed it was through the housing, but I'm pretty sure the silicone just is coming away), and worry about what this could do to my timing and overall engine health.

Possible causes:
Wrong head (Marked as 2.0L^T with a 1 underneath, with 0304 just under the CAS, and an A in a box above it)
Wrong CAS (olive green metal cap, so unlikely)
They broke the bolt/stud at some point, and put a new one on incorrectly.

Next... I'm tempted to take it off and strip away the stupid silicone sealant, then just put some washers under the nut... but that'd be likely to work itself free before too long, and the amount of gap makes me leery. It'd take 4-5 washers just to get any clamping force from the nut on the threaded section.

So they removed the engine hoist bracket that bolts to the throttle body and one stud where the cas bolts. Thats why there is the big space. You can either get a new bracket and put it back in or do what I did and just space it out with washers. I used probably 5 washers and one lock washer, hasnt come loose. I would definitely get all the silicone out of there!

Ahhh. Cool, I'll have to do that. Getting the silicone out will be more difficult, as they pretty much coated the O-ring. So long as the washers aren't going to work themselves loose, sounds like that'll work.

O-rings are cheap. You may as well use one.
If you have access to a wrecker, find that bracket and it'll save you some grief. Otherwise, looks like Roast Beef's got you covered.

Yeah, I'll have to call up the joint that dropped in the shortblock, and ask them if they kept it. :b Finding the O-ring is significantly more difficult... the stores around here only stock imperial parts, and AFAIK, all of the bits inside are metric. May have to ask them about that one too, or if I could hand them five bucks or something to scrape off the silicone and put on a new O-ring while they've got it off to put the bracket back on. :b I'm leery of driving it too much at this point honestly, don't want to screw my CAS. That in conjunction with the running super-rich problem means that it's garaged at least until I can get the AFPR on, once it gets here.

I was wondering why my manifold and turbo were glowing *brightly* at night, rather than the dull glow most mention. :b

Anyone got a pic of that bracket, so they don't do me a dirty and give me a broken/sheared one?
