Hi All:
First off, thank you all for your answers to my previous dumb questions ...
Now on to the meat of the problem. My '81 240d smokes and it's destined to be my so's ... and probable wife's ... daily driver. She doesn't like smoke, & I tired of being single (I'm 33!) so _please_ help me out here...
Here are my observations:
1) It smokes a _ton_ at startup. See attached photo and you'll get an idea. This is about ~1 minute after startup.
2) There's a lot of blowback (as evidenced by removing valve cover & observing vapor + oil in intake).
3) Oil consumption is large: at >1q / 500mi.
4) Smoke diminishes with time; the warmer the car, the less smoke there is.
5) The compression looks great (!):
Cylinder 1: 300 psi.
Cylinder 2: 310 psi.
Cylinder 3: 330 psi.
Cylinder 4: 320 psi.
6) The car starts on a dime; one turn & it's running no matter what the temperature.
What do people think??
Based on prior posts in this n.g. the valve stem seals don't make a huge difference, or do they?
JimSmith suggested the injection pump may be to blame ... any suggestions about diagnosing this?
I'm truly perplexed & my sex life is at risk here. Any suggestions would be greatly appreciated.
Many thanks;
