He runs now, had to let comp relearn the key...its leaking like a sieve from that coolant elbow, was new gaskets and everything. Damn. I'm getting smoke or steam from around the exhaust cross over...hoping its just spilled coolant and water where it was raining.

Coolant got around the elbow that'* it. Everywhere else around the LIM is still clean. I didn't see the new pcv valve in the kit, so I'll have to replace that, and get a new ECT sensor. So glad to have our car back. Thank you all.

Sorry, one more question, where do I add the sea foam to clean it out?

Did you buy a new elbow, and was it an aluminum one?
Or did you try to put new o-rings on the old elbow?
You can put a little of the black RTV you got from the LIM kit on the o-rings, and that may help, if you went with a new plastic Dorman HELP Elbow, then I recommend removing the elbow, replacing the o-rings with ones that came with the LIM Kit, should be 2 orange ones.
Use some added RTV for extra leak protection, just a light coat is enough.

With the Seafom, when I was done I poured some into the break booster line, which is the big hose that leads into the back of the UIM.
I had a friend start it up while I had a little funnel on the hose, I slowly pored in a little until about half of the can was gone, then I poured it in heavily till is stalled, let it sit about 1 hour, then started it up and enjoyed the smoke show.

So take the line from the brake booster itself, pour into that line. Excellent.

It was a new elbow joint I had on hand back when I did the tensioner, and I did put a little RTV around the gasket, though I didn't jiggle the joint, like I believe you had some luck with doing. Still need to replace the PCV valve, I also did an oil change right before work, but couldn't get the oil filter off. I figure that'* okay, I believe I need to do another one just to make sure all of the coolant is out

I also fixed all the vacuum lines I snapped with a bit of rtv and soft vacuum hose.

Another oil change a little while after the job is a good thing to do, after that I'd not be too worried.

I'd try to get the oil filter off next time though.

Mike,
In post 13 you mention that if you have a oil fill cap that looks like a sinus condition that it is a sign of anti freeze in the oil. I have that condition.
I don't seem to be loosing a lot of antifreeze, just a little. Is there any other cause that could be causing this condition besides the LIM gasket? I have a series II L67 SC and I replaced the gasket about 50k ago.

Did you use the regular plastic framed gaskets? It is possible that they are starting to fail.
