What is "pick up" on the cylinder walls?After many hours testing this and that, compression test found number 4 cylinder down by 95 psi in comparison to all the rest that were approximately 195 psi.
The endoscope revealed pick up on the cylinder walls and is almost definitely the cause of the nocking.
Removed the outdrive and the nock was exactly the same.
I have removed engine to my home and have received a Volvo Penta factory reman engine and in the process of building it up, will keep you informed.
Merry Christmas
