First off, motor oil leaking out the valve cover gasket is not going to just spurt out with hard braking, thats a bit of a stretch there. Unless the oil is just gushing out in which case there would be other issues. Next, motor oil even with the maximum allowed 2% fuel dilution still has a flash point approaching 300*. Good clean quality motor oil is going to have a flash point much higher, appraching 450*. Fire points are approaching 500*. Oil just does not ignite that easily and even if it does it does not burn well enough to sustain that kind of ignition with that little oil. Next, the oil would have to ignite, burn hot enough to light up the plastic tray the point out. Now, you and I know that that plastic is not going to ignite easily either as it is intended to survive a hot climate being that close to the manifolds.

And I base all this on stagnant air flow. It doesnt take into consideration of any vehicle movement that would cause air flow of any kind. Thats just going to make the ignition and sustainability of any fire that much harder.

Basically Im just not convinced that the valve cover gasket is the issue. I would say best case scenario it would take an extreme set of circumstances to generate that kind of fire from oil 'drops' as they stated. And they are citing what, 1 in a 1000 cases or something like that? I dont buy it.
I used to work for GM at a pontiac dealership and when I got this letter, I was kinda upset, because the letter clearly shows they really don't know what is causing it. However from my experience working on all types of 3800's, I don't believe it is from oil at the valve cover. I have really never seen extreme leaks at the valve cover and I have worked on plenty of these cars.

I have seen where fuel sits on top of the supercharger when the fuel lines leak though. And that would be cause for fire way more than the oil on the headers.

Check this.... I went to the Junkyard Monday and say 4 Grandprix's. None were GTP's. 2 GT's and 2 SE's....Tell me why both the GT's engines were burt to a crisp. BOTH OF THEM AT THE SAME JUNKYARD?!! And they say the NA's have nothing to worry about.
