Pulled the motor after several years of service from the 2056 build. Two problems have plagued me. The reason i pulled the engine was to seal persistent oil leaks. I am going after the oil pump and some gaskets and seals. The second problem has always been cylinder head temps. They are kinda high. I built the motor to have a 9.0:1 compression ratio, which works in my cast iron block, water cooled TR6. On further consideration, that may be a tad high. Especially after a few hours of highway driving in the summer.
The internet has lots of calculators to do the math. I can get or may already have cylinder shims. What ought it to be? The goal is dependable gobbling of miles with some increased power due a 2056. Suggested ratios? Guess i should have asked this question some time ago. Thanks folks. You are great. |
