So with the winter long and depressing evening etc upon us now I have started another long-overdue project.
Total rebuild of a model 40 Flathead V8.
It has been problematic for some time but recently it just won't fire up.
It has all the prerequisites for combustion etc but it won't, a wet and dry compression test I ran showed 5psi on one cyl and 40psi across the rest, well down on what it should be.
possibly rings but more likely poor seating valves to blame me thinks.
The solution, rip it out and rebuild it.
So that what I'm doing, it's not going to be 2-day project, probably a few months as parts are not as easy to obtain as you'd think.
It's buy no means a lightweight lump either, lucikly my block and tackle took the strain..lol
So far I've found a few areas that will require attention, all the valve will indeed need work, possibly new rings aswell.
One of the Main bearing journals has a nasty gouge in it , that will mean a complete new set...eek.
thats is it so far , a major cleaning session will be required and decoke as its very coked up.
well it keeps me busy is if I didn't have enough to do anyway...lol
so pic's as we all like pics.
