: Is it worth it?

I've had a 99 Deville for about 6 mos. Car has 80k on it and runs and drives well. Looks pretty good but far from perfect. I paid $4500 for the car.

It has always used oil, like a couple quarts between oil changes with no major external leaks.

Now I'm afraid it had the dreaded coolant leak. Fails the Napa Block Tester test, idles rough first start up of the day, a little bit of mayo in the reservoir and today the coolant was low. Also mpg has dropped off in last month or so.

So here's the questions:

1. Is it worth having the head gaskets done knowing that the rings are probably fouled up?
2. How long do I have before car becomes inoperable? Think I can baby a trip to California or should I address it asap?

I can't physicaly do the job so I would have to farm it out. Can anybody recommend a shop in western Oregon that has dealt with this problem?

Thanks!

Check out Carroll Custom Cadillac. They are in Washington state. I don't know how close to you, but they will know how to fix that N* properly and at a very competitive price. I think their website is: carrollcustomcadillac.com

Email Tim Carroll, @ Carollcadillac@live.com. He'll ensure you'll be taken care of, where in Oregon are you? CCC is located north of Vancouver WA in the Ridgefield area.

Thanks guys. Sounds like CCC is my best bet, even if it is a few hundred miles from me. I'm just so conflicted if it's worth putting thousands into this car, especially if it keeps burning oil like it does. I like the car but I don't love the car. Of course buying an 05 model or newer is plenty spendy!

burning oil should not be lookd apon as a bad thing with the northstar. You have a race bread engine designed to burn oil. The benefits of this are enormous. many members have torn down high milage engines and have found that the northstar has maintained its like new cylinder walls. Bearing failure is almost non existant and most of the little problems have been addressed by the year 2000. Not sure if the 99 has roller rockers but if not the cams will suffer abnormal wear due to decreased zink in newer oils. Once repaired your DeVille can be a reliable safe comfortable mode of transportation if you decide to learn about it and maintain it.

What makes you think the rings are "fouled up"? The fact that it uses oil (rather common) means that the rings and cylinder walls will be in fine shape. Note the factory crosshatched hone marks still in the cylinder walls of these 131K & 171K engines.

I don't know if I would take it on a trip that long.

By fouled up, I mean not properly broke-in or not sealing. It seems to use 2-3 qts between oil changes.

2-3 quarts between oil changes does not sound off to me at all. That's a quart every 2,500-3,500 miles. I'd take that in a heartbeat!

Mercedes diesels used to be designed to use a quart of oil, that is, to allow a quart to pass the rings every thousand miles in order to keep the rings and cylinder walls in good shape. I would say when your tailpipe emits curls of blue smoke when you descend a hill with the throttle closed, then sends out a choking cloud when you open the throttle again as my 49 plymouth used to do, THEN, you are "burning" oil. Just using some between changes that you never smell or see is actually a good thing.

The Mercedes diesel actually did burn the oil. Blue smoke out the tailpipe is oil that just got good and hot but not hot enough or had insufficient oxygen to burn.

Have you read the Technical Archives at the top left of the page (in the black bar)? It was written by a GM powertrain engineer.
