#348 of 482 Re: Buick Century: Intake Manifold Gasket/Coolant Leak [nevamarie]
Jul 31, 2004 (10:09 pm)
I have a 2000 Century with 115,000 on it. I started getting a whiff of coolant when I would lift the hood. In addition I started to see an oil spot under where I parked on the carport. I had read the posts here. I also started showing my oil getting low on the dipstick.
I took it to my mechanic who does my non warranty work and he told me right away what it was and explained why it happens on most cars who have that engine.
He did more than replace the gasket. I figured he may as well replace the plugs, wires, fan belt because none had ever been changed. Had an oil change with filter and new coolant. The cost was almost what I guessed, slightly less than $600.00. New PVC too.
He showed me the gaskets that he took out and it is apparent why they fail. They have a tiny rubber thread that goes around the outside just a bit off the edge of the gasket and I was advised that most of the time they fail first in one particular corner.
Does anyone know what that rubber was supposed to do? The replacement gaskets did not have any rubber in them.
#349 of 482 '05 Century - Special Edition
Aug 01, 2004 (7:27 pm)
I think the 16" chrome rims for the 2005 Buick Century special edition are the same chrome rims from the 2000-2002 Olds Intrigue. I was driving in Lansing, Mich. this evening (on s.b. Waverly Rd St. Joseph for those in the area) and pulled up next to a silver Century and though it was an Intrigue until I looked closer. The center lug cap has the Buick shield instead of the Olds symbol. I have an '01 Intrigue with these rims (minus chrome) and like them, but am surprised how GM used leftovers from Olds on Buicks.
Can anyone confirm this? Is this new for MY '05 or are these from the '04 year too?

Yes, those are indeed Intrigue wheels. Maybe they had some extra ones in a warehouse or something.

A reporter is hoping to interview Buick Century owners between 16 and 60 who love their Century and would like to be interviewed for a magazine article. Please respond to jfallonedmunds.com by Friday, August 13, 2004.
#353 of 482 Head Gasket yet again
Feb 04, 2005 (8:42 pm)
We've owned our 94 Buick Century Special Wagon for 3 years. At 1 1/2 years, the head gasket went, causing a catastrophic overheat which lead to the replacement of the entire engine. Today I noticed off-looking oil on the driveway, popped the oil cap off, and sure enough, coolant crusting on the inside of the cap. This time there have been no overheats, and a week ago the inside of the cap was clean. Can I hope to get away with a simple (only 500-700 bucks or so) head gasket replacement, or am I being overly optimistic? We've parked it, and will have it towed to the shop--not going to risk an overheat.
From what I've read, the 3.1 is notorious for head gasket problems--am I stuck with a vehicle that's going to require a 500-700 dollar repair every 18 months?

May be it is not head gasket, but intake manifold gasket? They are leaking often with GM 2.8, 3.1, and 3.4 liter engines. GM changed the gasket's material recently, presumably for better.

Good call--thank you! Still a pricy fix, but over 300 bucks less. Our mechanic says we can start with a stop-leak product, which may or may not fix the problem. If it doesn't, we'll move on to replacing the gasket.
Does this sound about right?

Would it leak outside, maybe stop leak could help. Not urgent: the car can run for several years with such a leak.
However, in your car antifreeze leaks inside engine. It is better to replace the gasket now, than replacing the whole engine soon. Hopefully it is not too late.
The job includes coolant system flush and oil change after repair. In Connecticut it costs about $650 at dealership, about $100 less at independent shop: roughly $50 gasket and bolts, $40 two gallons of DexCool, and $500-$600 labor. The numbers are for Chevy Malibu, with the same 3.1l engine.

I don't like putting stop-leak in a car. It's a temporary patch at best. This stuff can clog up your heater core as well.
