You also mentioned the draft tube. It is connected to a new Summit carb with a PCV in the middle of the rubber hose.

Is your setup similar to this -



Or this -

____________________________

Yes, except I'm using a port on the front of the carb with a PCV in line

Do we need to use a inline PCV ?????????

I noticed that on the head on the left, that there is a tube running to a drain hole at the top of the head. There is not tube like this on the head of my car.
Could this be the problem????
Get back,

Yes. If left off intentionally/unintentionally or if  the rocker arm assembly was pressurized with no relief, the oil supply can pool in the head surface and overwhelm the valve seals. The left heads usually sees more supply.

That's it !!!!
That tube is missing from the left bank for sure !!
Big time thanks.
NOW, where do I find these tubes ?
Any hints ?
Let me know,

AGAIN, BIG TIME THANKS

is there one on the other side.some people block these of.check to see if yours is blocked of which you can see just by looking.if thats the case start the engine and see how much oil is running in the heads.it should not run out with the rocker covers of.

TUBE - B5A 6588-A
SUPT - EBU 6575-A

Talk to the machinist first and see if he left them out for some reason. If he didn't, GOOGLE the PN's exactly as shown and you should come across them.

If You do need One pretty sure Carl would have a used One. He seems to have just about everything Someone is looking for. Helped Me out when I needed a missing Oil Slinger recently.

  

these must be pressurized rockers.there has to be bolts in those holes otherwise the shafts would turn as thats what holds them in place.
