I've had two differnet mechanics tell me that my 2GM has very low compression and needs to be replaced. It is raw water cooled and both mechanics are relectant to advise fixing it because it might be rusted internally. I would like to just fix what might be "broken" but I also don't want to be short sighted and have to fix parts of the engine every year. Can anyone offer advice? Does the 2ym15 fit easily in the 2GM space? Are there other drawbacks? Costs? Is there a realiable used 2gm for sale out there?
Any advice from someone with experience in this area would be helpful. Thanks.
