Due to factors outside my control, my garage is about the same temperature as outside and since we are going through the winter months, it will stay around 30F or less. I'm about to start overhauling the engine and I'm concerned about thermal expansion. If I start the rebuild in this temperature, will there be any problems with future engine reliability because of the expansion of the aluminum.

Further, I was looking over the procedure in the RAVE and wanted to know if anybody had formatted the rebuild specs into a worksheet that included tolerances, dimensions, and other important measurements.

I greatly appreciate your feedback on these matters

 

That's an interesting question. I would imagine that the dimensional changes due to thermal expansion and contraction within the range of 30 to 100 degrees F would be within the allowable tolerances. The pieces within an engine are generally not that large so it should represent a relatively small change in size.
