I'd like to assemble my engine but it's going to be a couple of months before I fire it. I'm concerned that the assembly lube could be gone by that time. I've read that a good 10-30 oil is an adequate assembly lube for a hydraulic roller engine except for using moly paste on the push rod and valve tips and the distributor gear. Is there something other than engine oil that can be used that will stay put for that long? I plan to pre-oil the engine with a drill before starting also.
