I need some advise on the cost of putting in an used engine for my 420SEL.
I got a blown heas gasget. I live in Orange County, CA. What is the going rate for removing and installing an used engine? Anyone has a good recommandation on a honest shop with good rate? Thanks in advance. John C. My car has 140,000 miles.

Why don't you just repair it? Your engine may be in better shape than a used on with unknown/suspect provenance. That engine is high-quality and long-lived if not abused by overheating or no oil changes.

figure about 10 hours to remove the old engine and replace with a used engine (assuming that the used engine comes complete with everything so that you don't have to transfer parts).

So the approximate cost would be the cost of the used engine plus 10 hrs of labor.
