high/low

Post by **les** » Sat Aug 19, 2006 10:05 pm

Does anybody know how to check an Ital piston for high or low compression, ie; depth of dish, number on top etc?

Dunno for sure - just eyeball it - if it looks shallow then it will be high. Engine number would give a clue - often has an H for high and L for low.

Les have you tried the Marina - Ital owners club.

If you don't know, why reply? There really isn't a need to reply to every single item, however nice it may look to have 10 posts with your name.

I gave two ways of telling - no-one else has come up with a better way so far!

Thanx Kevin, and thanxs for replying bm, but the eyeball method is too hit and miss for me!

The bigger dish in low comp pistons is very obvious.
The link to marina site is interesting too - thanks kevin.
