Compression results, hand-held (non thread-in unit, so accuracy is a bit less) all for 8 cranks
#1: 95 psi
#2: 100 psi
#3: 105 psi
#4: 95 psi
All within 5% of the mean, and nothing way off the mark. Test was repeated 5x, with very similar pattern of results on each repetition.
So, rod bearings? It does seem louder down below the pan than up top.
Is ther a differential diagnosis between rod bearings and, say, cam followers or ruined spring? BTW, there is no smoke at all form this car, either at startup or with acceleration.
Thanks for any help.
Patric
