50 more hours on new O-320 time to change the oil. Total 150 since new. Engine was run hard during these last 50 hours and consumed close to two quarts but oil temperature rare went to 170F mostly 150-160 I have larger cooler and plenum.
Discovered interesting phenomenon three out of four intakes had these strange oily tracks. It's not exactly pure oil but a strange tar like substance. It's easy to clean with 100LL. What is it?
All 8 intake bolts need to be tightened. There are two washers on each flat and crush. What proper torque values are for those?
I burned some gallonage of unleaded fuel 90+ octane mixed with 100LL if it helps. Running lean most of the time.
In this thread http://www.vansairforce.com/community/showthread.php?t=52548&highlight=intake+leak there is a suggestion of push rod tubes leak but I doubt I have 3 cylinders pushrod tubes leaking. Any explanation and advice appreciated.
