I didn't make the WCC because of this sound coming from the engine compartment. It didn't get louder when we plugged the tailpipe. I ran a compression check this weekend. Cylinders 1,2 & 3 were 100lbs +- 5%, but number four was only 50lbs. OK, the head is either cracked or the head to piston seal is gone. There are only 4K miles on the engine since Wayne Dempsey, Tom Gould and I built it in 2000. There was a lot of debate at the time on whether or not to include the copper "head gasket" and the popular advice was to leave it out. Am I to regret that decision? My 3.0 motor isn't ready, I haven't even started tearing it down yet, so I guess I need to drop this 2.0 liter, and repair the head leak, if I want to drive it this summer.

I read the that Technical Bulletin and it says remove the two and make it one
Eliminate aluminum seal 021 101 341A between cylinder and cylinder head. Eliminate paper gasket 021 101 341A between foot of cylinder and crankcase. Install 1.6mm aluminum shim 071 101 341, with adhesive D 000 400 at foot of cylinder to compensate for removed paper gasket and aluminum seal. Illustration 1. It sounds like your just removing the paper gasket and installing a thicker Gasket Oh this is fo 2.0 type IV 75-83 |
