Last March did a valve
adjust
. Later discovered slight oil leak from valve cover cap.Removed cover. Thought I'd QC my work and re-measure clearances.
Sure as sh$t, 3 measure LOOSE. WTFO?I was soo careful to follow the FSM to the letter. Checked and double-checked?
So what happened? How was this error introduced?
- Could it be that after 30 minutes of running, things 'settled' in to allow more clearance? Which led to this consideration.
-
- I routinely add engine oil to the bucket via a syringe. Is it possible that, in certain cases, the oil is 'trapped' in the bucket, creating a 'wedge' resulting in clearance reduction which in turn is increased by installing a thinner shim? Then, after some run time, the oil gets squished out, the clearance increase?
Just wondering about things on a rainy day...
