I recently had machine work done on my block, including a resurface of the deck. I've just noticed what seems to be a decent sized scratch. I'm curious if i can get by with it or if i should take it back to the machine shop where i had the work done. I have called the owner of the shop and he said to sand it lightly with sandpaper wrapped around a file. He told me if that didn't work to bring it in and he would mill a few thousandths off again. I want to avoid doing this because he's already taken off .010". What do y'all think?

 

Take it back.

 

Yep, take it back, just make sure they dont go past any mins on deck hight and such. If there are mounting studs, make sure they are also milled down to match the deck hight.

 

Absolutely take it back, if they made the scratch, and if milling the scratch out results in scrapping the piece then they bought it and need to replace it.

And it's obvious the scratch occured as someone was removing the piece from the mill due to it's constant radius.

 

Took the block back in today and he said all is good. Thanks to all for the advice.

 

your not near any cylider compression rings , although not real nice asthetically , should be ok .. but I did notice in your pics that the bolt holes are very dirty .. you need to clean those so you have no "bottoming" issues with the head bolts



.

 

ya take that mother back lol

 

that is exactly what the shop said. i started painting today so i'll take a q-tip and mineral spirits to those bolt holes as soon as i unmask it.

 

Be sure the head bolt holes are clean enough that the bolts turn in all the way freely by hand. If you're using new nead bolts you can cut a slot in an old one to use as a chaser. I'm glad I did. Had one in particular that really needed it.

 

Thanks for the advice! I'll be sure to clean them really well and use your chaser trick.
