Re: [DML] Good news for vin 2277 AT LAST!!

I just did a set of exhaust gaskets on a 24K mile car. I'd bet money 
that's what you're hearing. The gaskets generally burn thru 
underneath (there is a ridiculously thin area). Like Andy, I've never 
heard one where the ticking was really valve noise.

The best way to tell is adjust the valves, then when it still ticks, 
yank the engine and change the gaskets. It's a miserable job, and it 
is possible to do with the engine in the car if you are really living 
right. Unfortunately the studs often break, and there are several of 
them that you can't hit with a drill with the engine in place. 

Second best way is to notice whether or not there is more noise under 
load as opposed to at idle - if so it's definitely the gaskets.


I am fairly confidant its a valve tick. I have looked at the exhaust 
and it appears ok, the sound is definately coming from the valve 
cover. Is there a way to tell for sure?

The ODO says 37,000 miles (unconfirmed). I think a more accurate 
assessment would be around 60,000 as the angle drive was shot when I 
got the car. Dont think it would be much more than that, the engine 
is super strong.
