ENGINE AND ENGINE COOLING

 Engine hydro locked when a crack in the plastic intake manifold allowed coolant to be sucked into the engine cylinders, causing the engine to lock up while my wife was driving it. fortunately, no accident occurred, but this seems to be a very common problem due to what seems to be a design flaw by gm. we had to have the engine replaced, and the intake manifold, at a cost of $5,400.00. we heard that there was a class action lawsuit because of this problem, but people were just afforded a short time to act on it, and we were not even notified. is there another suit that we can be a part of? we should not have had to replace an engine with just 44,000 miles on it.

 Transmission: upper plate gasket went, causing gear slippage at high speeds which gradually became worse in the lower gears. transmission replaced under warrenty. transmission was replaced with a rebuilt unit which is now exhibiting much of the same slippage at high speeds (only minorly at the moment) @ 156,000km. engine: first engine had the egr/exhaust design defect that causes the intake manifold to melt and coolant to poor into the engine. report from the shop was that entire bottom end was destroyed by the coolant, and a full new engine had to be ordered (complete with accessories, etc.). the new engine's idler for the serpentine had the bearing cease, knocking the belt off. since the waterpump was belt driven, the engine overheated. the car was left to idle in the parking lot for a total time of ~ 5-15min. (the temperature out was somewhere around -40c / -40f.). brakes: perhaps cronically undersized for this vehicle, rotors have warped like clockwork every 30,000km. they are currently warped approaching 160,000km and will need to be replaced --- again --- shortly. this is not a car that see's much heavy use. groceries on weekends, ~ 15-20km max. total daily trip during workdays. it has yet to accomplish an extended road trip (i.e., north bay -> ottawa or north bay -> toronto, 4 hours (~400km) and 3 hours (~300km) respectively) without the 'check engine' light being lit. additional recollection: front fog lights constantly filling with condensation as well, have been replaced 4-5 times while under warrenty. no solution was found and now they're just not used.

 Gradually you will see a depletion of the anti-freeze from the holding reservoir. this is could be a sign that the intake manifold is beginning to leak anti-freeze (just a little) into the engine. sooner or later when the erosion is large enough then a plume of white smoke will come out of the exhaust and you have no choice but to pull over and call the tow truck. i have replaced the engine intake manifold twice on my 1998 olds 88 due to degrading of the interior wall where the anti-freeze flows back into the engine. both times the total cost of the repair (including plugs, wires, new manifold, labor) was around $1,200. on the last manifold gm had established adding a piece of metal where the anti-freeze was eroding the space age plastic intake manifold. based on this, gm knows this is an engineering problem, but they will not take ownership of it and or pay for it. *tr

 Coolant leak into engine caused car to run extremely rough to the point of having to stop. the car would not restart. had it towed to a repair shop. the engine had seized due to coolant leak resulting in damage to the head gaskets. the head gaskets along with the upped plenum had to be replaced at a cost of $1100. after research on your sight, i found this problem on several other 1998 olds 88 cars. i also found that a technical bulletin had been issued to dealers about this problem. why wasn't this problem with the upper plenum that is referenced in the technical bulletin sent to owners of these vehicles. i found the many other model of gm cars also use the 3800 engine with a plastic upper plenum that can crack over time from excessive heat.*ak

 Engine sputtered and shut down causing loss of power steering, power brakes, etc. fortunate not to have happened at high speed or in heavy traffic. the engine locked up completely and would not restart. cause was coolant leakage through crack in plenum which had to be replaced at a cost of over $700. this is very likely the cause of the following consumer complaints listed on your site: odi id's - 553119, 883623, 886028, and possibly others that were unexplained. i only searched for olds 88, but the same engine is used in pontiacs, and other gm makes. this problem is common enough to have been listed by the automotive service assoc. of arizona repair shops - see their website and an article under the title coolant leakage which explains the problem very clearly. the plenum is plastic, and is simply subjected to more engine heat than it can safely handle over time, causing the cracks to develop over time, hence the continual and gradual loss of coolant until it finally gives way resulting in too much coolant leaking into the engine to allow for combustion. as stated earlier, this engine shutdown could be very dangerous at higher speeds or in traffic. *ak

 This alternator growling/noise and tension pulley assembly began making noises at about 30,000. then at about 40,000 it really began making growling noises especially a lower speeds. then while we were on a trip to michigan and wisconsin visiting my relatives and children, it became apparent i had better get this fixed before getting back on the road to our home in bella vista,ar. some 750 miles. while in milwaukee i was advised to to see felsing service inc. 9128 w. burleigh st., milwaukee, wi. since gm dealerships could not guarantee me to have car ready as i had to be back in bella vista on thursday. mr. flesing said he could repair this. i wanted a new alternator, but none could be found in milwaukee. so i consented to a delco remfg. unit and a new pulley assembly.this was completed in a few hours. the bill was $388.10. i feel this alternator should last and be adequately functional for more than 40,000. but the very fact that no new altarenator for my vehicle could be found in milwaukee on that monday tells me, as i also have heard, gm is having problems with alternators etc. otherwise the car is a fine runnign car with good gas mileage etc.*ak

 In early 1998, i purchased a 1998 oldsmobile eighty-eight brand new from reliable oldsmobile dealership in cleveland, oh. although the car is a few years old, the problem i am complaining about began around may 1998. i went to the dealership on numerous occasions complaining about excessive, loud noises that were coming from the engine. the first time i went was june 1, 1998. each time the dealership tried fixing or doing something different, but they never fixed the problem. i endured the noise and the problem because i did not know of anything else to do. while traveling from georgia to ohio last summer (2003), the car finally broke down. the dealership in tennessee determined that the problem was a defective tension pulley. this defective pulley also caused an extensive amount of residural damage to the engine. this was the noise i was hearing . when i contacted the general motors company (the oldsmobile division has shut down), they ignored me except for telling me that my warranty had expired. i recognize that it has expired. however, the problem arose long before the warranty expired and could have been fixed long before it expired but for the oldsmobile dealership's failure to properly diagnose the problem. i do not think it is fair that a dealership can fail (deliberately or not) to diagnose a problem covered by the warranty while the warranty is in effect and then scream that the warranty has expired. particularly, after one of its own dealership diagnosed the problem. if the dealership in tennessee could diagnose it, then the one in ohio should have been able to do so as well. i wish to be reimbursed for the cost of this repair, which was $1944.67. i am not asking for the cost of the hotel room and the wages i missed, but it should have to pay for that as well. *ak
