A12 overhauling (Read 106 times)

Hi,

Anyone got experiences with overhauling an A12/A14 engine? What is the part that is likely to be changed? Okay, valve seals is the part that is most expected but what else?

Piston rings?

thanks!

is it still fitted to a car?

if so, you can check a few things to give you an idea of what needs doing...

compression and leak down test to show up wear in the bores/rings.

fit an oil pressure gauge to see how quick the oil pressure gets up from cold and check pressure when hot at idle and higher revs.
this will give you an idea on general wear in other moving parts.

Hi,

Thanks, that's the way to start.

Datsun used to be a bit smokey, mostly caused by valve seals I presume?
