Very good thread. I recently discovered that number six cylinder spray bar hole(s) clogged starved my oil head for adequate oil. Did the rebuild on my engine 2 1/2 years ago. I am curious to see what will be found in spray bar.

Can the dried sealants we have been talking about break off from the edges of the surfaces where they are squished and travel through the oil circuit causing these types of failures?

It would seem the potential for this is very dependant on the sealant location. For example, outer case sealant would go thru the sump intake side of the oil pump, and make its way thru the oil filter - thus no issue. The sealant on the oil galley areas has more danger associated, but since we seem to have a consensus that Loctite 574 is used in these areas, the excess should not dry up and would be swept along as liquid during the engines initial operation.

That is my theory anyway
