Probably about to pull out the die grinder and smooth out all the casting grit in the valley of a small block V8. Any thoughts or comments on this?

 

Good plan.

Anything you can do to aid oil drain back and get rid of potential chunks of casting flash falling into the engine is beneficial.

Just make sure you get all the gunk out afterwards and paint the inside of the block with electric armature enamel afterwards. Work the paint in with a brush, don't spray it on and it will be fine.

 

Never was a big fan of putting paint in an engine...

Always scared it would flake off and clog the pick up or something

 

we dont paint the inside of race engines either..some do some dont...however we do remove all casting "flash" and anything else we find in there and smooooothen out what we can get to. then its off to the hot water and the dishwashing liquid and then its clean clean clean everything and let air dry...zap!





hey max 'ol buddy...got a problem with this post?

 

Well I havent sent it to the hot tank yet, so I'll just coat it with WD40 or some used trans fluid or oil till I do. I really wasnt concerned about the grit coming off as much as I want aid drain back.

 

I thought it was Eastwood that made a coating you could use inside the valley or anywhere else you wanted that would help smooth out any casting ridges that might be there. It was designed not to flake or act like a paint, it's more like a chemical that bonds to the metal to make it smoother. I'll try and dig up the name of the stuff this afternoon if I have a chance.

 

Hmm I'd rather remove material than add stuff that might come off. It might take a few hours and a lot of sandpaper rolls but it would clean up and be very slick for the oil to drain back. I've already cleaned the outside of the block up.

 

the stuff from eastwood is called glyptal says here"seals the tiny pores left after bead blasting and leave the block interior smooth..keeps oil clean and flowing freely..acid and oil resistant and is used on generator and alternator armatures"..i guess thats what you want..comes in 12.75 oz spray or by the quart for 39.99 happy painting...zap!

hey max'ol buddy anything wrong with this post?

 

What would be the advantage to this stuff compared to grinding the pores smooth?

 

the only thing i'm guessing is that it fills all the pores in and gives a smooth finish without all that sanding and polishing...zap!

yaknow 'ol buddy max...i think we should bring this"disagreement" down to general discussion..where we all can get a grip on this...any questions?...zap!




anything wrong with this post 'ol self appointed "post policeman"

 

Exactly! All it does is fill in the pores and leave everything nice and smooth without as much work. My buddy used it on his 302 and it worked really nice. Just a thought...

 

You would be better off painting rather than grinding/polishing. As most engine parts are not high quality investment castings, some of the pores can be rather deep, and to smooth them out may lead to thin spots in the casting.
