howdy folks,
i have a 94 wagon non-turbo that,by the sound,and location has to be a stuck valve. car has gone 88k. what is the best way to attack this problem? i plan on doing the oil pan o-rings and timing belt,roller,and tensioners but first would like advice on the valve. sound is centered on oil filler cap area.
thanx

 

Hi,

As an easy inspection, you could perhaps remove the valve cover and try hand-cranking the engine to see which valve is stuck, if at all. You may want to have a new valve cover gasket after done, to make sure oil does not leak. This may be a 2-man job. Also, wait till others reply, other people may have better ideas than I do.

Good luck,

I would do the o-rings first. You might be lacking oil pressure not allowing the lifters to pump up all the way causing the noise.

 

I would follow Tech's advice

Tech is really good at these things. No doubt about him being on the top of the posters. If you’d be able to fix the problem, I guess you should also replace your Volvo valve cover gasket to assure no more leaks would happen after the repair.

 

There is no Valve Cover or Valve Cover gasket on an 850. There is a Cam Cover and when you take it off you have to use Volvo Gasket liguid when you put it back on. The Cam Cover is really part of the head and you have to be very careful when you remove it or you can crack the the cover or the head.

 

Jim, I suck

And I was rude. Sorry JPN!!!

I wasn't having a very good day at work when I wrote that.

 

Hi Jim,

No, there was nothing rude about your reply. I just sucked, like I sometimes do.

>I wasn't having a very good day at work when I wrote that.
Don't we all, those nasty execs, a co-worker getting in your way, another one trying to backstab...[8D].

I remember my aviation college instructor's saying that sometimes all a stuck valve needs is a light "tap" on the stem-end to get it free. I wonder if this was the case...

My bad day at work involved me making a mistake and basically shutting my company (a major insurance company) down for about an hour while we backed my software out of production. Told the boss I was sorry and I learn from my mistakes and I will never do that again. My fix was perfect, it just had to wait until night to be implemented instead of in the middle of the day.

 

What kind of software do you write?

 

I work on large mainframe applications. Have been doing it for almost 40 years now. Well minus the 15 years I spent in management which just wasn't for me.

 

Why do you say that? Too much bs, and no creative activities?

 

I like the satisfaction of doing something myself and getting some difficult problems solved, especially ones that others have not been able to solve. One time a VP told me that I could not be everybody's friend and be a good manager, and I said OK then I don't want to be a manger anymore. I took a big cut in pay to enjoy my work instead of dragging myself out of bed every morning to go to a job I didn't want to do.
