Long story short, the engine is out of the car. Loose head/cylinder studs are the suspected culprit. I'm planning on pulling the cylinders to lap them into the heads before I put it all back together. Will this necessitate re-ringing? The rings have about 8,000 miles on them.
Thanks for y'all's help! Konrad |

Here's the background:
The driver's side lost compression on both cylinders. The head checks out ok, no dropped/burnt valves. No apparent cracks or voids. This leads me to believe that the studs have backed out a little. They are not loose by hand, but I suspect they have turned enough to break the seal between the cylinder and head. The motor is a 2.0 Porsche case with 2.0 bus heads. My plan is to use this as a weekend driver until I can put a 6 in it, so I want to have a reliable engine, but without putting a whole lot of $$$ into it. Konrad |
