wd40 in bolt holes crack block?
Hey guys, im just running through my engine build and I have a question.. I used wd40 in my head bolt holes as a thread cleaner chaser to get some gunk and rust out.. I forgot to blow the holes out but Im sure there was very little wd40 left. Will this cause the block to crack? I also used the ARP moly lube, but ARP said to so i know thats OK. Will this be fine or do I need to re-do the head bolt holes? Let me know guys, this is scaring me lol.

The motor hasent been started or installed yet, its just somethign I remembered tonight and has been scaring me. There wasent any large amount, likely just the amount equal to if you used oil to lube the bolts instead of the ARP moly lube? Think it will be alright?

Personally, I would have cleaned out the bolt holes considering what you're putting at risk (the block). A liquid isn't compressible, including WD-40. If there was any damage to be done though, it would have been done while you torqued down the heads. There isn't any point in tearing it down now. Like Grimes mentioned, if nothing has happened, drive it like you stole it.

Cleaned them all out and re torqued head(ARP bolts, lol, saved me money already) and went ahead and put on the balancer as well as the rocker arms and push rods. Should be good to go for the swap tomorrow. I'm planning on tearing into it tomorrow, morning to night, then cleaning the engine bay and swapping accessories and everything that night in the garage.. Saturday should be the day for re installation.
