I posted similar pictures of the blow-by problem on my 83 about 6 months ago...
Here are different angles, I also cleaned off the top of the piston (#4). It is all pitted and also looks like edges broke off, melted and fused to the top. What could have caused this? Coud this have been prevented? My engine was running rough, then started smoking, on a couple of occasions, I could here the engine 'tap' really bad...Then it started smoking like crazy. Compression on the no. 4 cyl was <10 psi.
Thanks in advance,
ML
