Hi there guys... I got a small block 350 and i tore it down... I took the heads off an there was water inside 2 pistons... But i checked the head gaskets and the head itself and there where no cracks... Im going to send the block to the machine shop.. Hope the block isnt craked inside

 

probably isn't cracked,likely just rainwater that got in
if engine sat outdoors.

 

How well drained was it before the heads came off?

 

Pistons where full... The engie was removed from was friday... It didnt rain... All the oil was mixed with water... All brown... Drained? I donk know.. Still one of the rods was twisted

 

Sounds like something I wouldn't even bother sending to the shop.

 

Whaaat? I mean.. You mean it could be cracked from the inside and water passed over to the oil?

 

Could the heads have been untighten and then drained in?

 

With a bent rod and water in the cylinders it's a pretty safe bet there's a crack somewhere. It doesn't mean the block isn't salvageable, but the cost of any repair will certainly cost more than another core.

 

If there is a crack could i find it if i look for it? Just to make sure

 

Because i think i bent the rod while taking the pistons off

 

Ill have them do a vacum test before it gets worked on
