Well looks like my 3vz blew a head gasket. I know, I know, I've been on here before saying mine was doing great. I guess I have a bunch of unwanted work ahead of me.

Anyway, does anyone know of a way to determine which cylinder head is leaking before I rip it apart?

 

Could do a leak down test if you have the equipment.

 

Compression test?

 

Just pulling the plugs will tell the tale of which bank is leaking into the cylinder. In reality you're way better off tearing it all down for a reseal anyway though.

 

Don't have the equipment.

Thought about trying a compression test.

Ya I should really do both anyway huh?

 

yep, would suck to do one just to have the other blow out...
