Better check that again. I even found cone shaped ones for tapered head screws.Stuka wrote:The ones I have come loose are recessed allens.

The Weber uses a 2 piece adapter setup. Twice I have had to pull mine apart and re-tighten the bottom adapter. It uses these allens that can come loose.
Push oil out the valve cover typically means the cylinders are pressurizing the crank case and the PCV is plugged, making it go out the other hole. But you have good compression (120 is within factory specs). Strange.

140-145? Are you sure it has that many miles on it? Factory specs out 120-150, with 150 being brand new. If you are getting oil coming out, you are probably closer to the 110-120psi area on at least one cylinder.letank wrote:Same here, blow by on the 74, if i leave the oil filler cap off.... I can see the oil smoke on throttle down.. 349k on oem engine, working on a catch can, compression 140-145, idle at 21" at sea level, air filter fills up slowly.
Pict of your catch can set up, plz.
Trying ti figure out the best location....
Owned since 1983 at 78Kmiles, the last compression was done less than 2Kmiles ago.Stuka wrote:140-145? Are you sure it has that many miles on it? Factory specs out 120-150, with 150 being brand new.

Interesting. Makes me wonder how you could be getting blow by then. As those numbers are very high, and way higher than mine at 241k (mine are all sub 120psi).letank wrote:Owned since 1983 at 78Kmiles, the last compression was done less than 2Kmiles ago.Stuka wrote:140-145?
