Smoke
I have a reman motor from gm for 2001 gmc Sierra with 600 miles on it. Got a cam and longtubes as well. Today I got a tune and I notice I slight brownish white smoke when you get on it it was also doing this before is this fuel injectors they have 300,000 miles on them? It made 283 HP at wheels with a 212/218 is that average? Thanks

It sounds like oil getting into the combustion chamber.... Did the engien come with valve covers... The pcv valve isnt actually a pcv valve on these engines the pcv system is part of the valve covers... The pcv "valve" in the valve cover is usually just a dummy valve....

Yeah it came with valve covers. I had a cam installed and valve springs. The engine man told me he didn't have to take the heads off he just turned the engine up side down?

I pretty sure it didn't come with oil in it. Don't know why he did that he said heads may have to come off and the when I picked it up he said he didn't have to he just rotated the motor upside down.
