What guys in Denver are you referring to? I'm interested in joining that conversation. I would also like to know if I could replace the Isuzu transmission with a GM 4L60-E along with the LLR 3.7L.Originally Posted by pbkid

I dont remember the specific thread but there was a shop in Denver that was working on doing a 3.7 H3 swap into the VX, and also working on a grand prix swap too, if i remember correctly. Maybe one of the forum search guru's can help us out?

LOL, Yup, I remember this thread, but its mostly about the LH8 V8, not the LLR I5. I believe i'm the one who brought the LLR into the conversation.

Just a quick update; pulled the valve cover this past weekend to see if I had a valve hanging open but, alas, that wasn't the problem. Everything looked just perfect under there. No wear, no gunk, no build-up.
Have an appointment on Friday with a mechanic to do a leak down test. They will pump air into the cylinder to see if it holds any air (I doubt it will with no compression in that cylinder). If it doesn't hold air, they will then continue to pump air into the cylinder and try to listen where it's coming out. If they hear it coming out of the exhaust pipe then it's an exhaust valve problem. If they hear it coming out of the intake/throttle body, then it's an intake valve problem. If they hear it coming out of the dipstick, or see the oil bubble, then it's a cylinder problem (hole in the piston, blown rings, scarred cylinder).
Oh boy, can't wait!! (that was sarcasm)

Well, it's official (for sure this time), Vicki needs a new heart.
Went and had a compression test and cylinder leakage test done on the engine this morning and the results weren't good for cylinder three. In the compression test all cylinders had 153 to 157 PSI except cylinder three which read 40 PSI. When they performed the leakage test cylinder three didn't hold any air, or oil, at all. As they pumped air into the cylinder they clearly heard the oil bubbling by listening at the dipstick tube. That means that the valves are sealing fine, but either the rings are shot, there is something wrong with the piston, or there is something wrong with the cylinder itself. There's no way to really tell what is going on in there without tearing the engine down.
Could tear my engine down and try to re-build it, but who knows what we'll find once we get in there and that could keep the VX down longer than I can be without it. Might also find out that it isn't re-buildable at all, which would be even more time and money that I can't afford to spend. Guess it's time to start looking for a new engine.
