I have a 1986 CRX HF and want have the engine rebuilt. It has 260,000 miles on it and I would like to get another 200,000 out of it. I already pulled the motor out of the car and have the head and tranny off of the block. I live in the SF Bay area and called a few shops and got quoted $1,500-1,800. This seems very expensive and is more than the car is worth and more than I am willing to spend. I have never rebuilt an engine before but a few people have told me that it wouldnt be difficult to rebuild this engine. Should I attempt to rebuild the engine myself or leave it to the professionals?
