"1989 Mercedes 420 SEL Head Gasket Problems"

1989 Mercedes 420 SEL

A few months ago I bought a 1989 Mercedes 420 SEL, and it was very clean and well maintained course, with service records. However, there is a leak is very weak in the cylinder head gasket, which is hardly noticeable. Compression and leak down tests show no problems. It took two mechanics. They wanted $ 4,000 to fix it and encouraged in this regard. The other wanted $ 2800 and says there is no pain – only to see the oil and antifreeze, and keep your eye on the indicators. How serious is this problem? No antifreeze or water in oil or other problems and works very well. How long can I take it? If Mercedes head gaskets known minor leaks are not a big deal? I can not afford to fix it, but whether it is serious a problem.

Answer: Are you SURE this is a head gasket leak? I mean, really, all you say is that it’s a very faint leak and barely detectable. Head gaskets don’t normally blow like that. And the fact that there is no loss of compression and no leak down evidence suggests to me that this is not your problem. Before spending a huge amount of money, I suggest you take it too a mechanic. Don’t diagnose the car yourself. Say nothing. Just give him the symptoms. I think your self diagnosis is very likely WRONG.
