Appearance/surface of ring grooves after cleaning...

Featured Replies

the guys who did some cleaning and machining on my ea81t also cleaned the ring grooves. One of them in particular now has a whole lot of scratches on the upper and lower surfaces of the grooves - they dont seem to be deep at all when i run something over them, but they are very visible.

Is this an inevitable result of the use of a ring groove cleaner?

And does it matter?

-I can put a pic up if anyone thinks it'll help....

 

Cheers.

We don't usually get scratches from cleaning ring grooves. Unless there is upward gouging of the metal which would cause the rings to not fit properly, I don't see a problem.

 

If there are small ridges, you might be able to smooth them out with a very small, fine file.

Ok, thanks. I'm pretty disappointed with them - they seem to have been able to do two of the pistons without making any marks, another with only a few, but one looks a mess. Havn't really got the money for new pistons though (even though some 8.7:1 ones would go down a treat!), so i'll have to go with what i've got i think.
