The crankcase breather, ACDelco #CV870, on my '83 Surburban/6.2L diesel, is starting to spit up small quanties of engine oil irregularly, and my mechanic says its time for a new one. Before I accept this, I want to educate myself a little:
- What is a crankcase breather and what does it do?
- Is it adjustable? I see no obvious means of adjustment or opening.
- This online parts catalog seems to suggest that aside from the breather there are also breather elements that can be replaced separately:
I've googled for answers, but what I come up with are parts dealers, not information about the part.
Thanks as always, guys,
