89 new 22-re burning oil

[gbwsaw28]

1989 toyota pickup. CA. rebuilt engine (total of 5 miles). Burning ungodly amounts of oil.... more like dumping oil of out exhaust. Question is where is this coming from. Compression test: 120 psi across all cyl. I though it was going to be the head, but today i saw the intake manifold (viewed from throttle body) is totaly covered with oil on the inside.

My question to you guys, is where could this be coming from? I mean what could be dumping large amounts of oil into the upper half of intake? what even has access to engine oil. Thanks.

Who rebuilt the motor?? Whole rebuild or what?

I couldn't say, other than some company out in Texas, But it was a whole rebuild. I just bought the truck. But I think the 22-Re is supposed to have 150-170psi, so maybe it's back to the rings. The blow-by could be pressurizing the crankcase, more than the PCV can handle(PCV works by the way), possibly forcing oil through an airflow hose...

Oil is consumed evenly across all 4 cylinders. Coolant is clean. so that rules out head gasket/cracked block. I wonder if 1) The engine could have been slightly bored out, and original pistons installed on accident 2) someone forgot rings?

My truck was doing that on a low miles rebuild, it had 3 broken valve guides
