Piston & Liner advice.
Posted: Thu Aug 10, 2006 5:47 am
I'm planning how to keep myself busy through the long Alfaless Canadian winter and I think it's time I plug some new pistons and liners in my 2.5L.I rebuilt it a couple of years ago but kept the original pistons rotated liners 90 deg. and used Total Seal rings.I haven't been completely satisfied with the results:
-compression 160 psi +- 4 psi - rises to 175 with oil added - so the rings didn't seal all that well to the probably slightly oval liners.
-oil consumption leveled off at 1 L per 1000km.(600 miles) - not acceptable to me
So I guess that gives me a good reason to look at new pistons and liners and I would like your recommendations.I would like to raise the CR a bit,but not too much and would like to buy something "off the shelf" to minimize the cost (3 kids in school
)
So what can you guys suggest that I can obtain in North America ?
