no oil in cylinder head

1993 Chrysler Voyager 3.3 liter V6.
Rocker arm and shaft completely worn out/damaged in the rear cylinder head.
When trying to replace i found out no oil pumping to the cylinder head.
Oilpressure is normal and front cylinder head shows no wear at all. Mileage
is high (320000km).
Any ideas? One idea is that camrod bearing has turned in its seat and the
engine needs to be replaced. I have noticed a burned smell last 6 monts when
parked and smell seems to come from the right side of the car.

More then likely that is the cause of your problem, the Bearing has
turned, or the passage has stopped up, I have seen it both ways.,. That
doesnt mean that the engine needs to be replaced

Thanks for quick reply. If the bearing has turned, what to do? Understand
that i have to take engine out of the car to remove camrod. Haynes manual
states that replacing cam bearing is out of the scope of the home mechanic.
If the bearing rotates in its seat would that not ruin it and make it
impossible to put a new bearing in the same place?

Replace the turned cam bearing.

Throw your Haynes manual as far away as you can. Or set it on fire. Get
the FACTORY service manual.

Not necessarily, no.

Get the real factory service manual and see what's involved.

It has been a long time since I replaced a camshaft/bearing on that year
vehicle, Im pretty sure the engine has to be pulled because the engine
will not lower or raise high enough for clearance to pull the shaft out.

Lets see if i got this rigt. If the bearing has turned is that in relation
to the crankcase or in relation to the camrod? Is the problem that a hole in
the camrod and a hole in the bearng must be aligned or is it between the
crankcase and the bearing?

No such thing as a cam rod, what could have happened is, the bearing that is
inside the block (used for the camshaft) has spun, when this happens there
is no oil feed to that potion going up to the cylinder head

In relation to the engine casting.

A hole in the bearing and a hole in the engine casting (what you are
calling the crankcase).

The camshaft (I assume thats what you mean by "camrod") spins in the
bearing all the time. If the bearing has "turned," it is by definition
turned in relation to the engine block.
