Jeez Lorne, I am not but an old self taught amateur who`s thinking is well past it`s sell-by date, as has been proven on this forum from time to time, add to that the obvious effect that the passage of time having taken it`s toll on what little grey matter I may once have had, thus anything I type tends to ever have a question mark over it, and ever open to being corrected by anyone. Many thanks for your kind thoughts from our time on eMog.
The main thing for folk here is to concentrate on is trying to help Jeremy get his +8 back up and running..?.
Lastly if the engine was last shut down with normal oil pressure evident, then the relief valve would logically be in the closed position...? Thus it seems to me that if the valve stuck due to lay-up, it would be stuck closed, and likely have no effect on this issue....UNLESS, immediately prior to lay up the ign being turned off immediately after it was given one last rev up, causing the pressure to rise and open the valve causing it to perhaps stick open to some degree in that situation..?
