Jroc Posted August 3, 2015 Report Share Posted August 3, 2015 So my truck just recently started consuming oil and spraying out the dipstick? I did some research and figured it was a bad PCV valve, but both part stores I went to say my truck doesn't have one? Is it different on an 05? I pulled the vacuum line off from the intake to back of driver side valve cover, and tried to pull the barbed fitting of the valve cover (the part I thought was the pcv valve) but it doesn't seem to wanna budge its like its just part of the valve cover. Any ideas? Thanks. Quote Link to comment Share on other sites More sharing options...
Thickcajun Posted August 3, 2015 Report Share Posted August 3, 2015 I'm pretty sure its built into the line.... Quote Link to comment Share on other sites More sharing options...
Downeast Johnny Posted August 3, 2015 Report Share Posted August 3, 2015 The fourth comment down in this post, the guy says that the PCV is built into the valve cover and not replaceable. In the second linked discussion there's a guy talking about cleaning his PCV out with carb cleaner. The guy in the second link had oil coming out of his dip stick tube also. http://www.gm-trucks.com/forums/topic/128805-oil-in-intake-manifold/ http://www.silveradosierra.com/engine/how-to-fix-pcv-problem-on-silverado-t21123.html Good luck.

Thickcajun Posted August 3, 2015 Report Share Posted August 3, 2015 Maybe a 05 is different but this is what we pull off of my 03... It wasn't actually built into the line now that I think about but it plugs directly into the valve cover...

I think mine must be built into the valve cover because there is nothing in-line, I will try cleaning it out like discussed in the second link. Thanks a bunch guys!!

Jroc Posted August 5, 2015 Author Report Share Posted August 5, 2015 Pulled off the valve cover today and cleaned out the fitting, wasn't totally blocked off but flows better now after some carb cleaner and shop air. Will drive it tomorrow, hopefully it did the trick, stay tuned for updates. Quote Link to comment Share on other sites More sharing options...

Jroc Posted August 6, 2015 Author Report Share Posted August 6, 2015 well bad news, drove her today and its still having all the symptoms as before. I'm at a loss as to where to check next, I really don't wanna do a compression test because the procharger makes it a major pain in the ass, but I guess I will just have to man up and get my hands a bit dirty. I am just really doubting its the rings because the truck isnt down on power at all and I just had the heads off and all the cylinders where in good shape.

Downeast Johnny Posted August 6, 2015 Report Share Posted August 6, 2015 Did you check to make sure that the hose connected to the PCV valve was clear? I guess that if that hose was bad, (not getting enough vacuum to the PCV), You would know it with rough running. (Thinking vacuum leak from a split hose). Maybe it is blow-by. Somethings got to be making pressure in the crankcase. Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted August 9, 2015 Report Share Posted August 9, 2015 My wife's car had the exact same issue. Tons of crank case pressure would come out of the dipstick tube and the oil fill cap. The only fix was to replace the valve cover as her PCV was also built in. Once done, problem was solved. Quote Link to comment Share on other sites More sharing options...

12'SROCK Posted August 11, 2015 Report Share Posted August 11, 2015 You said you had a ProCharger correct? if so you need a one way check valve so when you going to boost you do not pressurize the crankcase . Make sure you have a check valve on the vacuum side of your PCV hose Quote Link to comment Share on other sites More sharing options...
zippy Posted August 23, 2015 Report Share Posted August 23, 2015 The driver side valve cover on the SS's don't have a pcv valve stock. The earlier one's had a fixed orifice valve which actually had no valve in it at all and the newer valve covers basically have that built into the valve cover. Since backfires are a thing of the past the need for a valve wasn't there anymore and the fixed orifice pcv became the way to go for a consistant amount of air coming in for the idle circuit. If boosted you need to make some changes. If you have the type with the removable piece simply order a pcv valve for a 2000 or so camaro and install it in place of the fixed orifice piece. Once in boost the valve will close and not allow boost into the crankcase where as stock it would just take boost from the intake and fill it up until it pushed the valve cover out. If you have a valve cover with the fixed piece you need to either add in an inline pcv valve (many are available) or replace the valve cover for a type to install a normal valve into. Make sure to check the passenger side also. The hose from the passenger side valve cover should go to the air intake side of the supercharger and not to the throttle body or intake manifold. Left stock this will also quickly fill the crankcase with pressure. Quote Link to comment Share on other sites More sharing options...
