The cars been sitting for about 2 months due to a loss of compression on cyl#2. from 190-205psi on cylinders 1-3-4. Cylinder number 2 gets 60psi on a semi cool day this was back in october.
Before the compression loss I had put a new head on there with about 100k on it due to over torquing the timing chain tensioner bolt(torque wrench was broken come to find out from the owner of it) and had loud lifters so I ended up replacing the head with a clean one instead. Bought the cylinder head gasket set from bavauto and went to town on it. Did the proper torquing procedure following the bentley(thanks to fredK) and the car was fine for the next few months.
October came by and I had parked the car for about a week. Next day when I started it it just idled like crap and stalled out. So me thinking, Im like okay could be a vacuum leak, dirty ICV or just the colder weather. So I start it up again and just hold the RPM's up till operating temp. Once at operating temp I let the car sit at idle and its just idling as if it had some huge cams in it so next things first I ask around a few people and I go to town on doing the compression test and come back with the results above.
The car has been sitting for 2 months because I have been thinking on either an m50 swap or just rebuild the m42.
SO can you guys help me out on getting this issue resolved? There is no coolant mixing with the oil so the headgasket being faulty is at a 25% chance of it just having damage near that cylinder. The spark plug of that cylinder is oil up pretty good and is causing most of the misfire and I am thinking its the rings but the car is not smoking nor burning much oil.
