Valve cover gaskets labor

Post by davolvo »

Hi everyone, I am going to have my valve cover gaskets, timing belt, water pump and radiator replaced. I am buying the parts online. The place that works on my car is wonderful but I was a bit puzzled when they quoted me 7 hours of labor on just the valve cover gasket replacement. Does that sound right?

Thanks!

Yeah, that sounds right, because you do not have valve cover gaskets, if this is the 6 cylinder engine.
What you have is a sealed head top, with special glue/sealer from volvo, both cams have to be removed, hours spent on cleaning both mating surfaces and then regluing.

I wonder why you feel the need to reseal? If there is an oil leak, and the head is the original with no past work in it's history, the oil leak is probrably from an cam seal or the the oil filler gasket. Has your flame trap been inspected lately?

Unless you know for sure it is leaking at the mating surface, then don't touch it.

Hi danr960 and Jonc123,

I am glad I asked, yes, I own a 1996 960 that just rolled over 200,000. It runs great! I am leaking oil and ordered a new oil cap because I was told that could of been it, it wasn't but the new one fits better. I don't know what a flame trap is, so I guess I will have to say, no, it has not been inspected. Is the cam seal replacement very complicated? What is the oil filler gasket?
Since I have to get the radiator replaced do you agree that it is best to change the timing belt and water pump as well? I really appreciate your input. I really like my volvo and want to do what is best for it! :)

The oil filler gasket I pointed out would have come with the new oil cap you ordered, the cap itself should be okay, it is the gasket that gets dried out and cracks.

Oil leaks are tricky to locate, with the air flowing thru the hood area, a leak can be up front of the engine and oil is blown to the rear or around to the rear face of the engine block. Most oil leaks are caused by the flame trap getting clogged, making internal air pressure greater and blowing past the cam seals or the main crank seals. A little detective work should locate any problems with the oil recovery system. It is made up of three hoses, a flame trap and an oil trap. The flame trap is located at the air intake duct, it is a 1" rubber hose that enters just before the throttle plate. The oil trap is located under the intake manifold behind the alternator. At 200K miles, that very well could be it. You might have to clean your engine and see if you can determine. It is entirely possible that the oil is leaking from between the mating surfaces, especially if some one had done some head work in the past.

One can never change their timing belt too often, especially if you don't know the vehicles history. Changing the water pump is also prudent. You might also go for the dampener, tensioner pulley and idler pulleys too. But once those items are taken off, it should be easy to determine if they need replacement. But the interval for timing belt changes are I believe 70k and so those pulleys and tensioner will not be looked at for possible a number of years.

Is there a picture of the flame trap anywhere? I read somewhere to just take it off and toss it. My oil leak is getting worse and worse. Thanks for your help! :P
