oil in head pipe

[hemipower]

i recently pulled the 2.9 from my broncoII to install it a 88 ranger in great shape, the install went without a hitch except the motor started smoking like a freight train. I pulled the 2.9 back out and in doing so when i cut the headpipe I saw oil had been enter it through the head any explanation for this maybe valve stem seals or what?

Maybe hes asking about the exhaust manifold?

I think he is asking about the Y pipe between the exhaust manifold and cat converter. Maybe oil is leaking out from the valve covers down to the exhaust manifold?

the head-pipe I refer to, is the y-pipe,and no it is not leaking from the valve pan.and the oil returns are not stopped up any advice

Have you done a compression check? might just be valve guide seals.
