SOURCE: how to replace valve cover gasket on a 2002 stratus 3.0 liter engine

i don't know that vehicle very well... but there are usually bolts/screws that hold them in place. 4 to 6 of them per cover. sometimes the spark plug holes have giant nuts that hold the cover in place.

SOURCE: valve cover gasket leaking

When you buy the valve cover set, it will include the spark plug well "O" rings. Simply remove the valve cover and on the underside of the valve cover, you'll see the "O" rings that need replaced and you'll see exactly how the valve cover gasket itself fits.

SOURCE: 1992 chevy siverado pickup 350 engine,I have a oil

you definately should check the oil pressure switch its probobly above or to the side of the oil filter and can make it look as if the filter is leaking,it will be threaded into the engnine itself and will have a connector on the top of it most likely with only 2 wires going to it

SOURCE: replace valve cover gasket

I have the same problem on a 2003 Town & Country. The cover for the front 3 cylinders is quite straight forward, but in order to do the rear cylinders I believe you are going to have to remove the cowling below the windshield. You will need a gear puller to remover the windshield wipers first, then remove the cowling. Than should give you more room to work. It's still not going to be easy, but it sure beats paying hundreds of $$$$ in labor charges.

I removed the oil cap and there was a lot of pressure coming out on my 2002 Chevy trailblazer ltz 4200 is that a major problem and also is there a PCV valve on this motor


First, there is a PCV valve, unless someone removed it.
A local car parts store or garage should be able to tell you where it is located.
Second, a lot of pressure ( usually called "blow-by") can be a problem.
Blow-by that is extreme can blow the oil out of your engine whilst you are driving it, and cause motor failure.
I should recommend you deal with the PCV valve first, and be certain the pipes and or hoses are good to it, as this has a lot to do with blow-by.
Other than the PCV system, blow-by can also be caused by worn rings on the pistons or worn valve guides.
God bless your efforts.

No oil filler spot only dip stick and valve covers where do I put oil in chevy 350 block engine


Has to have one. Look around, should be located on your valvecovers, if your valvecovers don't have a place to put oil in, I suggest buying a cover that does and installing it.

We took off the breather cover on a 2004 chevy trailblazer and there was water in it


Sounds like you may have a bad valve cover gasket. same thing was happening on my wife's Chevy Aveo. Valve cover gasket was worn and when I replaced it and cleaned plug wells, issue was resolved.As for the breather, I really wouldn't know why there's water in there.Only thing I would suggest there is to check your antifreeze level. Is it water from the antifreeze?

2002 Chevy Malibu - Oil in Coolant Tank


Sounds like your head gasket has a leak. I would also check your dip stick. If there is coolant mixed with the oil also. Then it is your head gasket.
