That is not the oil causing the failure, the seal was already worn and the oil did its job cleaning out the sludge plugging the bad seal.quote:

This has happened many times before by someone switching from DINO to synthetic on this board. RP and Mobil 1 have done this to more than a few BITOG members.
When the balance between Ester and PAO is not just right for a given seal, causing the seal either to expand or shrink, seal failure is prevalent.
With a little patience, the oil might actually re-swell the seal within a couple 1000 miles.quote:

Ok, first off, I don't think RP has detroyed my seals because it was only in my car for one day.
As far as the extra clearance, my machinest, who is a friend of mine told me 5 thousands. The extra clearance is recommended for my forged pistons. When a forged piston heats up, it expands.
To play it safe, I believe I'm going to go back to the Havoline 20w50 SL.
Anybody have a paint strainer and need some slightly used Royal Purple. I'll make you a good deal. (ha, ha)
All valve seals can handle synthetic oil.quote:

James408,
You're going to have to pull the valve covers and replace the valve seals. After that, go to a mineral based oil. Not all seals are able to handle synthetic oils. I just hope that your other engine seals are alright. BTW, 20W-50 is too thick for a motor with just 5000 miles on it. Go with 10W-40.

You have a very good point there.quote:

James408 don't sweet it. If your only getting a little blue smoke on a cold start don't worry about it. Take it from someone who owns three forged piston motors. It not that unusual for a Forged piston motor to do this a minor amount until the pistons get warm and expand better. Ring seal is not optimum on a cold start due to piston rock at TDC. Cold start piston rock is a byproduct of the required bore clearance for forged pistons. If it was doing it with the motor warmed up it would be a different story.
BlazerLT, who are you quoting? Those are not my words.quote:
