Hi All,
I love this community. I have used the search function a bazillion times to gather invaluable information to help troubleshoot and DIY's on my 73 2.0 fuel injection. I have been working on the body for years and have it in pretty good shape. The interior as well is almost done. I have gone through the suspension and replaced shocks and tie rods. New vacuum hoses, rebuilt injectors and all new stainless steel fuel lines. I have worked my way around the engine, and still need to put a new CHT on as it reads cool. Any whoo, I did a compression test today and these were my readings. 1. 110 2. 105 3. 100 4. 130 Some big variances there. Spark plugs are all dark. Is it rebuild time? Recommendations on best DIY rebuild sources books, blogs, youtubes, this forum etc. I want to keep it pretty much stock but am interested in putting the european style pistons in the car. Any other recommendations and opinions are much appreciated. Thanks, Gary |
