Rebuilt Engines (archive)

HEllo,
I'm looking at a 3.0 CS as my next car ... the two that are listed in the classifieds in my area both have rebuilt engines. I was wondering if such engines are usually reliable? (Of course, there are many things that could go wrong if the job isn't done right, but if it is.. is it nearly as good as a new BMW engine?)
Thanks...and one quick question .. is there any older (pre 90s) BMW model that has a hatchback?

You are correct when you say that many things can go wrong with a poorly rebuilt engine, but if done right, a rebuilt engine can actually exceed the reliability of a new engine since the block was "seasoned" by its previous cycles.

That said, it does depend on the quality of the parts and labor involved.

Given the fact that many "unopened" M30 engines have exceeded 300,000 miles and were still running well at that point, I cannot imagine that even a minimally "freshened" engine (valve grind, new rings, bearings and seals)would not reach that point in even better running shape.

I would not avoid purchasing a BMW with a rebuilt engine if it ran smoothly and had no obvious signs of problems (noises, smoke, etc.).

Given the cost of a "new" factory engine (upwards of $7000), I cannot see how anyone could justify this avenue if his engine were just in need of new consumables (rings/bearings/seals).
