Thanks again for all the help from everyone. yes motors and everything is very clean. Hope to get some use out of it next season.

sometimes back flushing works,sometimes you need to use a coat hanger to push the junk out of the tubes.

or thin needle nose plyers that can grip well - use to pull out pieces on the back side of the oil cooler plus use an inspection mirror and a light. or do what Mike said - also depending on room for either method to pick which way is going to work best per your app.

Cleaned ps/oil cooler, will pull water pump next week and back flush block and probe with bore scope camera, going to pull raw water pump and double check. New gaskets are on order for the exhaust logs to risers. Great information provided thanks to all! Merry Christmas!
