ok guy's update i just pulled all the plug's and check.all i seen was normal wear just a little carbon around the bottom ring part's.and a little on oil on the thread's!but i believe it due to valve cover's.what else should i check?thing valve seal's now

That would be my guess is the valve stem seals....

thank for your help.i will be trying to do the compression test friday.when my gaugae get here.will let you know my psi.will write it all down.

Ok as i told ya would let you know the compression test.driver 165 psi on all cylinder.pass side 165 psi.on all cylinders and keep in mind this was without oil.and ya the engine was warmed up.what yall suggestion next valve seals guide's?

That would be my guess, you can probably use your compression tester with some slight modifications to it to use compressed air to hold the valves in place as you replace the seals....
You can also try the TDC method but that requires more effort in moving the crank for each cylinder...

Okay thanks made up my mind.gonna take it to the shop.when i get the brake's done and let them check it out.i dont have the shop to get into alot the engine stuff.

how much am i looking at for valve seals job?

All of the seals will cost less than $20... if you pull the heads and take them in it will be pretty inexpensive, HOWEVER you will need to re-install and adjust the valves...
I would call around a few places to get an idea... also consider calling a couple of dealerships as that will give you a reasonable baseline...

Depending on handi-capable you are this is something you could probably do in a weekend... but do your homework and know your specs and processes...
you will need to drain the coolant if you pull the heads... which also means new head gaskets and bolts and pulling the intake...

If you do it on the vehicle you will only need to pull the valve covers and find a method to keep the valves from falling into the cylinder while you remove the rocker assembly and springs and install the new seals....

Even if you do have it done, look up some youtube videos on the topic so you have an understanding of what is being done...

Yes i can agree.i know how to do it just dont have the shop.will let someone do it.
