kevink Posted December 19, 2009 Share Posted December 19, 2009 hi guys, i just read all the info i could find and i really want your opions on this.I've got a breather filter in place and my pcv valve where it should be.i noticed my breather filter got really oily so i pulled i off while the engine was running and it is blowing huge amounts of air out....2 possible options i guess:pcv valve of piston rings... (really hope its pcv)the thing is when I throttle a bit it stops blowing air out the vent(where i have a breather filter)does that clearly point the problem to a faulty pcv or does that surely mean the piston rings are fucked?

StarletRick Posted December 19, 2009 Share Posted December 19, 2009 do a compression test. but tbh, its probably nothing, they tent to "blow" a lot on most of the EPs ive worked on. Quote Link to post Share on other sites
kevink Posted December 19, 2009 Author Share Posted December 19, 2009 thnx for hte fast reply Rick, kind of comforting to hear that.what about the part that when i push the throttle it doesn't blow anymore?i would think that if it were the piston rings it would only build up more pressure as the pistons move faster.or is that wrong to think that?

kevink Posted December 20, 2009 Author Share Posted December 20, 2009 bump..anybody? Quote Link to post Share on other sites
starletgt troy Posted January 17, 2010 Share Posted January 17, 2010 I had this problem on my car, dont wanna put a downer on your hope but mine was the part on the piston that seperates the rings had snapped, do a compression test and this will locate the cylinder which is at fault. Hope this helps Quote Link to post Share on other sites
Russleh Posted January 17, 2010 Share Posted January 17, 2010 im sure the pcv valve closes under boost. might be why it stops blowin when ya put throttle down but i have no idea how much your pushin the throttle so could be wrong Quote Link to post Share on other sites
Aga Posted January 17, 2010 Share Posted January 17, 2010 how old or how new is your engine? blowing up to a point is normal, blowing smoke is bad... Quote Link to post Share on other sites
kevink Posted January 18, 2010 Author Share Posted January 18, 2010 hi guys,i checked my pcv valve but it works as it should.No smoke whatsoever, so thats a good thing.I replaced the filter with an oil catch can that breathes freely. I think the amount of blowing is normal, car does not show any other signs of worn piston rings.I am going to replace the rocker cover with a completly clean one.

RobSR Posted January 18, 2010 Share Posted January 18, 2010 I'd only really be concered if it was throwing quite a bit of oil out.. I'd do a compression test just for peace of mind Quote Link to post Share on other sites
kevink Posted January 18, 2010 Author Share Posted January 18, 2010 will do when i get the chance.With the oil catch can hooked up i can can an eye out how much oil it really spits out.Driven it for 2 days now and nothing in the catch can so far, the hose running to the oil catch can is only slightly oily, but thats normal.
