2.7- Big smoke on start after sitting
The 2.7 in my 914 is a Motormeister motor-not looking to start a Motormeister discussion, the car came with it, and its been strong over a couple a/x seasons and some hillclimbs, plus the price was really right. It's running high comp J&E's (GE40's, Webers, crankfire, not that any of that is relevant).
The car has always smoked heavily on startup after sitting for a few days, but it clears right up, runs great, and doesn't burn appreciable oil. The PO warned me it would do this, he claims Roy told him all J&E's do that. Obvious BS. I'm not looking to tear the motor apart over this issue, but I'm wondering what the collective braintrust here would suggest as the cause-and whether I should be concerned about it, or just live with it until the motor needs to come apart for whatever reason.

On my 2.7, (JEs) we set the clearances just a little large so it smokes a bit on start-up (after setting for a week or so) and clears up. The oil tank is positioned so that the positive pressure head allows oil to "flood" through the rings, gets into the cylinder heads (and sometimes through into the headers. . .); this causes amazing smoke. Don't worry about it. If you've got good numbers all around and it doesn't smoke all the time, drive it like you stole it.
Edited to add that my 2.7 is in a 914. . .

Ok, mine is in a teener as well. Maybe I shouldn't have been so quick to criticize Roy. The smoke is amazing, given that the car has no issues and doens't "burn" oil.
