Paint block? Wrist Pins? And More!

[flagoworld]

Greetings,

 

Paint Block: I just received my block back from the machine shop. Shiny. Factory, I believe, had it painted black, right? Should I re-paint it? If so, what is the recommended paint? Regular ol' black engine enamel?

 

Wrist Pins: What's standard procedure here? I have my set of used pistons, but they did not come with wrist pins. Should I look for new wrist pins and have them fitted to the pistons? Should I use the old ones? I cannot find wrist pins for sale at first glance, so maybe I will have to put up a WTB?

 

Assembly Grease: Recommendations?

 

 

Thanks

Yes it came from the factory painted black, I paint my blocks light gray so any fluid leaks will show up clearly, I use hammer- rite paint and it holds up at block temps just fine any other brand I would go with engine paint just to be sure. Have your old wrist pins checked out with your pistons to start with they may work fine or not but have your machinist check the fit first.

I've seen a lot of wrist pins and don't think I've ever seen a worn out wrist pin.   More than likely if anything is worn out, it is the bronze bushing in the connecting rod.

thanks

 

checked my wrist pins and they dont seem worn out. might try to get new ones since they appear to be fairly standard sizing and many websites sell wrist pins. if i cant find any, ill reuse.

 

opinions on painting over freeze plugs? any reason not to? not finding any good reason not to on the google machine

 

went with lubriplate 105 assembly grease

Having trouble finding information on painting the block behind the flywheel. Is there a standard procedure for this? I would like to do it but have seen pictures of blocks not painted there.

The area behind the flywheel is fairly well protected and you don't have to paint it if you don't want to but on other hand there is no reason not to paint it if you want I always do.

Looks to me like that block was shot-peened? (check with machine shop).

If so, suggest checking all oil galleys, bolt bosses, and every nook and cranny for leftover media ... you don't small metal 'balls' to be part of a new build. -KB

I'll be sure to check with them on what they did. I carefully inspected for leftover media and found none. Either they did a good job of cleaning off the leftover, or they didn't use that cleaning method.
