2002 Impala with 3400. Severe coolant leak from front of right cyl head area. I just replaced both head gaskets and intake gaskets to try to fix. I could not see a real issue with any of the gaskets but everyone said leak has to be one or the other. I can pressurize the cooling system and see coolant pouring down top of the block where the head meets it but cannot see exact spot where coolant is coming from. Appears coolant is spraying back towards the head/block. Can the front cover gasket be leaking or can the front cover have a crack. I have not found any info on coolant leak in this area other than the head and intake gaskets issues.

 

The 3.8 's have a coolant elbow that is a common problem in this area. I don't know if the 3.4s use the same part/design. No cracks in the head, block or intake?
