I did hear noise on that side weeks ago but wrote it off as an exhaust leak because I was missing a bolt on manifold.
He retested the cylinder compression yesterday and it was 110 but he’s not sure his gauge is completely accurate. Friday it read 75, then 30 and 35 when it wasn’t even working.
After tightening up the stud and rocker nut on the cylinder not working it was 100 then 110. The cylinder in front of it was 150 and another on passenger side was 170.
He thinks his gauge is off but that cylinder is still lower. Will any compression come back after it’s actually started and I drive it some or is that permanent?
On a side note I was thinking of putting one of those Pertronix 1 lobe sensor units in because my points didn’t look great. Anyone try those?
