Fine metal particles in PCV catch can
I installed a PCV catch can and ME Wagner adjustable PCV almost 1k miles ago. I wanted the general benefit of a catch can (keeping oil from recirculating back into the intake) and I also wanted to see what/how much was passing through.
I'm not getting that much oil in the catch can. Probably 2-3 oz every 500 mi. But there is some very fine metal at the bottom of the oil in that catch can. No large particles, but just dust. Some of this could be from the threads of the catch can, which is pretty tight. But I'm worried it may indicate another problem (cam lobe, something else?). The engine seems to be running fine, other than oil consumption (I'm changing the intake gaskets again this winter). I'll get an analysis done next time I change the oil.
But could this be normal? |
