Default Upper Intake Gasket Leaking

Noticed a half-dollar sized drop of coolant on my garage floor this weekend. Dealer just called and it'* the upper intake gasket leaking. I haven't done much research yet. They just fixed the throttle body leak recall two months ago! I'm wondering if they didn't get things buttoned back up tight. When it rains, it pours I guess. Sounds like a theme in these cars.

Yah, it sat for about 18 months or so, driven a few times in there. That was one of my concerns when I got it, gaskets that is. Hopefully, that will be the end of it. With only 15K miles, I sure hope so!

Good catch, Hans!

Cars and houses do not like to set unused. They deteriorate quickly. Obviously, gaskets and O-Rings dry out unless they are kept lubed by use. Same reason that your A/C system benefits in winter by being used for the defrost cycle. The lube is internal and the O-Rings dry out if system is not used.

If they do have to replace the upper gasket it might be worth it to upgrade the UIM. At least inspect closely the area in proximity to the EGR stove pipe for degradation. I wouldn't think on a car with that low of miles it would be any problem though. Just a few thoughts.

I thought GM fixed the problem after 1999 with smaller EGR pipes so that the UIM wasn't detriorated by the proximity to the hot EGR.

Does this mean the problem still exists? Or is this a different problem with gaskets sealing and drying out?

Get the revised on when they replaced it they put in on all 2003 and later 3800 L36'*. Good luck, and I am glad that won't be a problem on mine

Yes, You are right, I was in error. I've heard that the EGR stove pipe diameter is smaller alledgedly in the 99, 2000+ engines.
