Just an FYI, some shops still have had the old gasket in inventory and have been using that to do the repair with. It absolutely must be the new style with the new sealing method.

 

Breather filter is a bandaid fix. Your basically giving yourself a vacuum leak by doing that.

Do a compression test before anything, kits are about $15 at an auto part store.

 

Yep , you have to find the cause of the over pressure. A breather is just giving the air another place to release from.

 

I had the same problem and mine came from a bad cyclinder. You could fit a screwdriver between the piston and the cyclinder. That led to a rebuild. Rebuild isn't done yet so to see if its fixed is still tbd.

 

yes it does. but it's built into the valve cover. the hose going from the back right top of the cover over to the intake tube is the crank vent hose. make sure it's not clogged.

definitely do your compression test too.

 

Hey man... I know this is off topic... but I have a 2009 G5 GT and I was thinking about getting those headlights. Do you have any more pics??

 

I am going to guess that your motor is toast. I am guessing compression in one of the cylinders is roughly 115 or lower. Time for a rebuild!!

Again this is just a guess, a VERY educated guess, cough this may or may not have happened to me last week cough cough.

 

great i hope i don't need a rebuild but i cant do compression test until next weekend

 

how do you do a compression test on this car what do i need to unhook so it cant actually start

 

#1 take out all your spark plugs

#2 disable ignition by disconnecting the ignition harness

#3 disable fuel by disconnecting injector harness

put compression tester tube HAND TIGHT(NO MORE) starting in #1 cylinder and connect gauge. listen for about 6 engine cranks, check gauge. repeat for other cylinders

 

should a compression test be done on a cold or hot engine

anyone i am trying to do this now i need to know if i should warm up my car before doing it

 

do both if you'd like. the warm one is going to read a little higher due to expansion of the rings but cold engine really lets you know if you have an issue

 

I'm sorry, but every time I see this title, I think of the "Now that's thinking with your dipstick, Jimmy!" commercial!

 

ok i am going to do it cold then thanks for the help

just did the compression test it was 210 for all 4 pistons

now i still need to find out y my dipstick popped out after i changed the intake manifold gasket

what else could make my dip stick popped out and how can i check it

 

seriously, pinched or blocked pcv valve or hose. try swapping valve covers and make sure the hose is clear of sludge or debris.

 

i know the hose is good because i took if off and used a air hose to blow it out

 

i can sell you a breather i got it from jegs ( high preformance) it go's into an ls1 but works just fine on our car's i have used it but now i am going to get a polished cap. pm me if ur interested

 

^^^^ carefull ^^^^ The PCV valve is actually in a cavity in the intake manifold! The hose comming off the valve cover has nothing to do with **** you can actually delete it and put a vacume cap on the intake and a filter on the valve cover... It looks nice too!


Always do a test on a warm engine!!!!!

 

bump does anybody actually know how to test for a properly working PCV? this thread beats around the bush. tia

 

ever take off the valve cover and clean the **** out of it? all i know is i did that to my ex's saturn and there was sludge all over that **** clogging up her PCV

 

ringlands cracked... stop driving

 

this thread is old news man, got any input on my post #44? pcv test, valve cover breather is not the pcv
