Hello! I have had this car for three years. I have put a lot of money into it, with the idea that I would keep it as long as it runs okay. And I thought my mechanic was on the same page.

My problem now is thin slick of oil (not transmission fluid) on top of coolant reservoir. Already did head gasket replacement and cylinder machining but that was two years ago.

My mechanic, who I do trust, says I should not pay more than $600.00 to have anything done, like to have the engine torn into to find out what is wrong. He says the car is not worth that much. While I appreciate his concern, I just put $1200.00 into the engine last fall at his shop, tracking down vacuum leak and other engine issues.

My question; if I do have an honest mechanic would I be stupid to put more money into the car? We have fixed a lot of things, but I know there are plenty of parts we have not repaired or replaced. It runs like a top even now. No sputtering, smooth shifting, it runs great and obviously I will keep it as long as it does.

Can you please let me know what you think? Thanks so much!

Colleen

Go with your mechanic, the car is 16 yrs old and even if you like it you can get a newer one with the money you have to put into it or just let it go keep an eye on fluids. If one is going down it will show up.

Thank you for your helpful information. My mechanic is going to do an oil change this week with Lucas oil treatment. He said that might slow the leak? Do you ever recommend using Bar's leaks stuff? Since the car is nearing its death anyway, would it hurt it to put Bar's main seal in it, in addition to the lucas treatment? What about coolant leak stop? I normally don't think about using these things but now it's not like they are going to hurt anything - might they give me a little more time before I have to replace the car? Thanks so much! Colleen

I am not a big fan of additives as they seldom work but I did have some moderate success with a head gasket sealer to try to stop a head gasket leaked it worked for a couple of months as I didn't use any coolant. Seal leaks are best fixed by replacement and not an additive but try it if you want i'm not going to say no

If you're not getting water in the oil as well then the issue almost has to be a crack in the block.

Lucas shouldn't hurt it BUT none of the coolant system leak stoppers is going to help. The reason is that oil is under much higher pressure that the cooling system. Any type of cooling system sealer is designed to flow into a coolant leak and plug it. Some do work for that purpose. However in your case you have oil at 40-125psi pushing into the coolant that runs about 15 psi max. It would be like you trying to push a running bus backwards. Just not going to work.

Now as to is it worth it? Is the car paid off? Is the body in very good shape? Do you like the car? Are you in an area where the body is going to stay rust free for a long time?

I would ask the mechanic, What would a used engine swap cost, What would a re-manufactured engine cost, Also a re-manufactured short block. Then at least you have some numbers to use.
