Hello guys
You might have previously read I am having some random rough engine issues and just waiting on couplers for the leakdown test. Anyway, started the car yesterday and whilst cold there was quite a bit of puffing out the oil filler hole. its not something I've done previously so was a but unsure? Clean air, not smoke.
Now, reading online as you do it appears some 'blowby' can be expected, presumably more on a cold engine with thermal expansion decreasing the tolerances of a warm engine. The PCV is there to suck gasses out, but I think I might have too much at 90000miles. The car idles perfectly well, not rough or lumpy.
So, have you guys ran your engine with the cap off? What's it like? Oil shouldn't go splashing everywhere if the cap is only off for a minute or so (well maybe unless you rev it).
