I have a oil leak could that be a blown head gasket? It's a 91 4runner. It still has plenty of power but it looks like its maybe coming from the heads in the front of the engine
It's hard to say from that description, but a blown HG would probably present as more than an oil leak. You'd be burning oil and/or coolant, which would show up in your exhaust.
for the front, the valve covers are the common oil leak, & the oil pump is common for the lower.
although it it possible for an oil leak from the head gasket, the pressure is so low that it is unlikely.
