I have about 1,500 miles on the engine refresh. Noticed that it puffs blue smoke when I shift gears. Checked the compression and it is about 130# on all four cylinders. Ran non-detergent oil for the first 500 miles then changed to 20W-50 Castrol. Changed it again yesterday and went with 10W-30. It was nasty black and looked like it had 8,000 miles on it instedaed of 1,000.

Got the cylinders and Hastings rings from Jake. Had Len Hoffman do the heads with new valves, guides, springs & retainers, welded up plug holes to 12mm. The CR is 8.6:1. Running DRLA 40's w/ 32mm vents, 55 idle jets.

The car runs great but seems like the rings should have sealed by now. (IMG:http://www.914world.com/bbs2/html/emoticons/blowup.gif)

If anything it is running lean. I have been going back and forth between 55 & 60 idle jets. The 55 that I am running now pop a little through the carbs when it is cold. Once the temperature comes up it runs better. It runs at around 300 degrees.

Is there anything I can do at this point? Can I take it back apart and re-hone the cylinders? Seems like 130# of compression is low it had 145# with the old dished 94's.
