Default RE: 99 Deville Engine Oil Leaking - Stop Leak Treatments

There was/is no recall for leaks.
My main seals were replaced under a recall. It included 97-99 Devilles with Northstar. I'm not going to argue or dig up my paper work which is a letter to me and then a $0 work order, just suffice to say GM Canada did the job at no cost to me. I guess GM Canada values customers more than Cadillac Motor Car Division.

its happening on all cars regardless of maker and origin.

There was/is no recall for leaks. There is one for a small number of 99 4.0 & 4.6 engines that the head bolt holes were drilled too deep and could lead to head gasket failure. Recall info in FAQ section if your vin falls within vin break contact dealer. On a different note. Head gasket in a can gets another victim. A friend of mine just bought his son a 2000 Land Rover notice it didn't appear to have antifreeze in it when they got it home. Drained and filled with antifreeze, now has blown heads.

Hi All,
Firstly Happy Christmas and a prosperous new year to all of you, I found this forum through good old Google whilst on a desperate search for help after being caught out by your classic used car dealer - a guy called Jim Harper of Harper Motors in Decatur Illinois. the Pristine looking Cadillac Seville SLS with honey colour clean coolant and oil on inspection and a clean engine vomited its coolant up all over the driveway 4 miles from Harper Motors and so the nightmare began - many wierd happenings and today 2 months later and $2000 less - I am pulling this motor from hell out and replacing it, my skin is thickened by all the promises and all the bull I have been fed by so many in the vain attempts to screw me further, in 2009 I will drive my properly repaired Lemon that I will have turned into a peach by sheer willpower and determination.(ex South African)

I am however glad I found all of you - the many who also have endured this forced learning curve by a cold greedy dealership and manufacturer who make it difficult for the enthusiast to fix his car - Dealer quote to transplant my engine was $3900.00 - gofigure! - i will do it myself.
Sorry to hear that your start with a Cadillac has been tainted by a dishonest deal.
what year is the car?
what was the diagnosis? headgaskets? cracked block?

welcome to our site
maybe we can improve the Cadillac experience ...

I am unsure what the problem was, but .. I will take the opportunity to point out an ongoing issue ...


advice to all:

when buying a used car with an aluminum engine, do a COMPRESSION TEST,
this advice applies to GM, Cadillac, Ford, Honda, Toyota, MB, Porc, Chrysler, etc., etc .. no car with aluminum engines are exempt from the advice.

the failures of seals due to the coolant issues are ever increasing, catastrophic, and expensive to fix.

I am seeing these coolant related trends on many sites .. and yet .. few are doing anything about it.
Please, read the FAQ on this site regarding the coolant and headgaskets .. take preventive action.
YES, it is preventable.

I looked for a recall on NHTSA's site and a bit on the web, but didn't really find anything out about a recall. I don't think the stop leak products are an answer, especially after reading the post above. The problems with the engines and transmissions should have been well known to GM even when my car was built. Perhaps these problems were known, but it's no use crying over spilled milk.

While it is important to know that aluminum based engines are less durable regardless of the manufacturer, it doesn't excuse a particular factory for sloppy engineering, knowingly using inferior/inadequate components, and tolerating poor build quality. I've owned 24 cars over the years. I have a short list of cars that I will not buy again. VW, Suzuki, Audi, Saturn, and Cadillac make up my list.

Default 99 leaks

There is a campaign (recall) # 99086 issued on 4/19/2002. Your vin number must fall between these two vin's to be repaired. XU791675-XU802142. Mine fell just outside of the end of this vin number, still has all of the same problems listed in all the inquires and post, Cadillac will do nothing. Lv the caddy, the feel , the ride, but hate the repair cost. Back to the shop tomorrow. New level system not working correctly. It's been adjusted two times and still is back a-- up in the air, which causes stress on drive-shaft, front suspension, boot axle's, tie-rods etc..... plus causes fuel system not to operate correctly.
