All Sealed Up – Timing Cover
It’s always good to replace every seal in a motor when you’re tearing into it. But, it seems that all the motors I’ve worked on the seals will start to leak within a few years. The manufacturers had it down to the 3 year or 36,000 mile mark for components.
So we replaced the crank seal in the timing cover. I was given a tip to wipe the seal with laquer thinner which should help it hold a seal better for the race motor. Prior to that I was advised to wet the seal with a little oil.
Any engine builders out there who want to debunk either one of those suggestions? Feel free to post a comment. The one piece rear main seal of the Ford 302/351 always seems to weep a little. Even within a few thousand miles. I’m all ears for ideas on how to keep it dry.
