09-27-2010, 07:05 AM #1Hey guys, I'm pretty new to the forum and wanted to get some opinions. I'm looking to buy an '87 300SDL that has a greasecar kit in it. I've looked the car over pretty well and it seems that there are little mechanical concerns. I am concerned with one aspect though, and that is blowby. After driving for about 40 mins (mostly testing the turbo, the guy claimed it had just been rebuilt) I pulled over to check things out. Opened up the crankcase and noticed oil was sputtering and a little smoky. Didn't get too good of a look because I didn't want oil sputtering all over the block. With the cap just resting on the opening, it sat pretty nicely without bouncing around. The car has about 220k on it, but I was wondering if that seemed like a concern to some of you older and wiser guys? I know blowby is in all engines, but do those symptoms seem reasonable for 40 mins of hard driving and the mileage? Do you think I should be concerned?

The tea kettle test will only tell you if your engine is about dead, its useful for noobs who dont know what a diesel is supposed to run like. The only real test is a proper compression test. Chances are its ok. Whats the head stamping?

haha I take it you don't like wvo?
I'm not sure what the head stamp was; I know that car had problems with the head cracking though; is that why you're asking?

You might have some ring gumming
Veg does that sometimes.Water injection seems to cure it.
THere was a guy in another forum with a E300TD who had exessive blowby, oil stick poping out, rough engine and all, he misted some water in the manifold while driving and it cured it.
Grenwrench here has a water injection in his car and he's happy with.

Sputtering? How bad?
