Quick valve adjusment question
 
After adjusting the valves do you coat the valve cover gaskets with a thin coat of oil when you are assembling them? I'm using graphite gaskets and this is a 2.4 MFI engine.

Thanks!

Install them dry, graphite is a dry lubricant. I would recommend buying the silicone gaskets they are reusable and seal the best IMO.

yes on the silicon gaskets, they are great, can be reused over and over.

Thanks much.
Next time around I'll get the silicon gaskets.

One more question...(this is my first time)

Should I let the car sit overnight after completing the adjustment before driving it? I thought i read that somewhere...???

Do the adjustment stoned-cold....but not heard of sitting overnight before driving....

Interesting footnote.....But I don't see why?

Best,

Doyle

Never heard that one. I just adjusted my valves and immediately after putting everything back together took it for a ride.

x2... I've heard this as well...

The theory is it helps the rocker cover gaskets seal as they have a chance to "mould" to the covers before being heated for the first time.
Apparently once the gaskets are heated for the first time they loose some of their compliance.

That kinda makes sense...

dshepp806 07-17-2009 02:29 PM

Interesting,...look to hear from the P-wrenches here on this one ...never even thought about this one...

..quite interesting.

Best,

Doyle

just go back and retorqe the covers after its warmed up and cooled back down

I think it makes more sense to let the car sit over night (cool) before adjust. After adjusted, why need to cool it?
