i have a new engine built by the pros and it now has a hole in the front of the block on the lower left hand side looking at the motor by the lower timing cover. It is about the size of a dime. There has been oil leaking from somewhere and now on the 4th time having the engine removed to see what can be done about the hole. It looks like a chunk of metal has fallen out of the block all the way down to the pan gasket. It has cost me a fortune trying to fix the oil leak and now it looks like the block is the cause. Im almost out $2000 in extra labor trying to fix a brand new engine. Anyone ever seen this and how should it be handled. The place that built the engine said it was not their fault and it really is not , but they are the ones that sold it to me brand new. Should i go straight to world and who should i talk to?
