Buick Riviera Engine problems by year

It started out as a small oil leak, but I recently noticed the leak has expanded significantly. It's difficult to pinpoint the leak, but an oil pan under the car shows significant puddling of oil. A sealer/conditioner doesn't appear to have been affected. While online, I noted that the 3800cc 3.8L engine seems notorious for this problem, and other models of gm cars appear to be subject to a recall. Not so the buick, which to me, has the same engine. Given that is is known now, I'm concerned that this low production vehicle was left out of the recall and should be included. Puddle of oil photo enclosed. This condition is most noticeable while the vehicle is stationary.

Well for starters the car has 131,000 miles on it and clean interior. But....The drivers side power seat incline doesn't work, the blend box or an actuator is bad, the cruise control doesn't work, and the ac compressor is locked up. But.... The worst part is the oil leak coming from the front valve cover. It is spilling out on my exhaust manifold and smokes badly. I just read gm has a recall on all the l67 3.8L supercharged motors in grand prix and regals amongst other models with the 3.8L but not the rivieras. Can...

I smelled gas. I opened the hood, removed the engine cover & fuel was spraying from the plastic fuel line, the size of a pinhole. I contacted the dealer to order a new fuel line and was told the fuel line part #25648136 is discontinued, as soon as I find one left somewhere, I will be taking to an independent repair shop for repair. There are no recalls listed on this? A dangerous situation. I went into various auto forums on the internet & noticed that several other people were having the same problem. A pinhole...

This is an intermittent issue and has been occurring at different times since purchase in 1999. While driving engine stalls and I lose power steering control. Experiencing long cranks before engine will start. However, engine eventually restarts but engine stalls again several times before car will run without incident for a brief period. Have had numerous repairs done on this car regarding this issue such as ignition module. Had repairs done in october 2013 where crank shaft position sensor, mass air flow sensor, cylinder and key were replaced. In april 2014 began experiencing same issue again. *Tr

The info above is approx. Your recall of gm cars with re: to ignition problems may not be broad enough. I traded in my 95 riviera in april of 2007 after plowing $1500 into and still no satisfactory repair on why it was stalling. The last stall was in a three way intersection in chicago. Each time it stalled I lost power steering. I don't recall if the dealer looked at ignition issues. I do recall that they were at one point focused on the carburetor. It was being serviced by a dealer in schaumberg, ill. Sorry I don't have better recall of details. Once I traded the car, I tossed the documentation. The last stall was scary and the reason I traded the car. *Tr

Gm has recalled 1997-2002 pontiac grand prix and buick regals wit the 3.8 Liter supercharged v-6 engines for oil leaking and burning on the exhaust manifold causing some 267 known fires. I have a 1997 buick riviera 3.8 Liter supercharged engine which has begun doing the same thing recently. I have not seen the riviera included in any web search but I am sure gm is trying to get by without repairing as many 3.8 Supercharged as possible. *Tr

Vehicle - 1997 buick riveria 3.8 L supercharged engine -- oil leak from front valve cover gasket -- recall just released for 1997-2003 buick regal and grand prix but left the riveria out of the recall list for the exact same engine --- I replaced the gasket myself (very expensive gasket) - 11/05 -- and feel that gm should at least reimburse me for the gasket ---. *Tr
