528e engine rebuild

[dresslered]

Hello all. This is my first post and I am already in need of some good advice. My beloved 1983 528e finally popped a head gasket during a moderately paced drive over my mountain commute. In doing so, it also burst the radiator. I’m thinking that the rapid pressure from the cylinder getting into the water passage packed just enough punch to break the plastic neck where the radiator hose normally attaches. The car idles just fine but there is a nice mix of water and oil (sludge) in the coolant. Anyway, the engine has 275,000 original miles on it (oil/filter changed every 3k), but the car is in beautiful condition. Rather than just replace the head gasket and have the head checked out (rebuilt), I am thinking that I should probably just have the whole engine rebuilt at this time as it was starting to consume a little oil prior to this event. It is no longer my daily driver, but I would like to ‘at least’ put it back to the condition that it was when new so that it can go another 275k. Can anyone recommend a shop in the San Francisco Bay area (Santa Cruz) that can ‘properly’ rebuild this motor? I realize that I am probably looking at spending $5000+ for a proper rebuild on a $2000 car, but I really like this one. Also, what additional services should I also request during the rebuild (polishing, porting, etc.)?

TIA
