Re: torx specs

Jobassing.... The only reason a connecting rod bolt would come loose would be that....<br /><br />1 - It wasn't torqued properly in the first place.<br />2 - The wrong connecting rod cap was installed, or the proper cap was installed backwards.<br />3 - The engine was running lean (in which case, the crankshaft should also be damaged).<br />4 - The bolt has lost its temper (strength). Replace the bolts on that rod just on general principles.

Jobassing.... To check a VRO, run the rebuilt engine with a oil mixture in a portable tank along with the regular VRO setup. Clamp the oil line with a small pair of vice grip pliers near the engine. The warning horn should sound off (every other second) within a short time as it is obviously not drawing oil. If you get no warning, either replace the VRO or eliminate it.
