I have a 1990 535i with a manual transmission that needs a new engine; the current one runs, but is nearing a time when it is going to need some significant attention including a head gasket replacement, and whatever else makes sense to do at the same time. I am thinking about purchasing a new rebuilt engine and am looking for feedback and experience from anyone else who has don this from where you bought the rebuilt engine to putting it in the car.

I am an "experienced" shade-tree mechanic and feel confident about "replacing" the engine but I would NOT consider myself qualified to rebuild one. THANKS IN ADVANCE!!

PS - I have a VERY SIMILAR condition with a 1984 e23 and will be posting a similar message there. Both are high mileage and I want to keep both.
