blown engine

[MissSylvia]

I have a 1999 Grand Prix GTP Supercharge (my baby) I had an intake gasket replaced at Pontiac Dealer, less than 3 weeks later the bottom bearing of the crankshaft went out. Extended warrenty refuses to pay , saying dealer is at fault. The warrenty company says they found small debri in oil, after numerous tests. But, I had not really ran the car much till the day all H broke lose, I had just started passing a vehicle on the interstate when my car died I lost all power and every dummy light on the dash lite up. After pulling off road I was able to restart it, but then the loud clanking noise started. My question is...could they have not grounded the supercharger and it caused this problem?? This has been 7 weeks, I contacted a lawyer , he has been no help. I wish I could give more information, but I am just a female,lol
Thank you

Well to tell you the truth, there is no relationship between the gasket they replaced with the bearing that later broke. The only reason a bearing will break like that is because the oil pump died and the bearing did not lubricated properly or that the bearing was to thin when oem installed it(I doubt that but not impossible) or just plain and simple the car ran out of oil.
Is the engine oil pump working properly(If it's not then the extended warranty should pay) or the car had good oil level(if not the the last people that worked under the car are liable) and if the bearing is to thing compared to the other 5 then was a parts failure so the Extended warranty should cover it

Well when the bearing breaks then naturally, the oil will be contaminated with metal filings and metal debris.
I would contact the warranty company again and have them honor the extended warranty.
Make sure you got your maintenance receipts. Have your vehicle checked and get repair estimate and opinion as to what the cause was from 3 certified automotive shops.
Have a male relative come with you to file a warranty claim.

Slade, that is the business side of the solution. Awesome

Thank you very much, I do realize the oil pump was probably the problem. Amazing how I never had any problems till I had it worked on and I took it to a Pontiac dealer thinking that would be better. I miss my car, I bought a really cheap car until this could get settled...Geo Metro,lol
Thanks

A metro? You are in my prayers......

If I had to bet the problem with your car was not the intake gasket. The problem was your Plantum. The EGR valve has a tube which runs through the plantum which causes it to melt the plantum and allows coolant to get into the crankcase or the intake. If the coolant gets into the crankcase it will mess up the crank and the rod bearings.

The male relative can be helpful, but not always. My dad makes me deal with any and every problem that crops up...up to and including getting what my car is really worth from an insurance claim. If you happen to not be able to get a male relative to help, your best bet is to learn enough so that you can at least sound like you know what you're talking about when you deal with them. Unfortunately, the way things work, you're gonna have to sound like you know twice as much as any guy would (Even though there are guys out there who aren't interested in cars and really don't know anything about them)

That's what happened to my wife's 98 Bonneville. It did it right when I started it up and I only drove 30 feet before I shut it down. Still it cost $600 to fix.
