Hi guys, I decided not to install the external oiler and I just finished disassembling, cleaning and reassembling my rocker arms and ready to install as suggested by everyone. I looked at the oil hole that feeds the rocker shaft and it looks clear. I inserted a wire that went in about 5 inches straight and hit something solid. Is this normal. I thought that there was an offset channel in the head that connected to another hole which would of not allowed me to insert a wire 5". What am I missing.

Thank you- AR

No, you are correct, alls good, the wire goes down the oil hole in the head and will stop on the block, there is a channel about 1" long in head surface which lines up to oil hole from camshaft oil supply, assuming thats reasonably clear, oil should appear at rockers.

OK,

Appreciate the response.

If you haven't yet I would still turn the oil pump with a drill motor to see the oil come out before reinstalling the rockers.  If you have a cross drilled cam you will need to rotate the engine slowly by hand to line the holes so oil will flow.

Oil pump is counter clockwise rotation.

  

I am reporting that after disassembling and cleaning the rocker arms oil flow has been restored. During this process I did noticed that I have a light sludge built up in the engine. Is there a "gentle" way of slowly cleaning the engine without causing other major problems or just leave it alone. Thanks again- AR

Great to hear you fixed the oil flow.Congrats on a job well done.Depending on how bad the sludge is and if its "solid" in place I would leave it and change the oil regularily.Just my opinion but you risk bits plugging oil gallerys if you try and remove it with scrapers etc on the heads and lifter valley if you take the manifold and centre pan off to clean inside.

  

AR; An often contributing factor in sludge buildup is lack of crankcase air circulation. Make sure your crankcase air intake, which on a stk engine is only thru the oil filler cap screen, is clean. If it won't cleanup well, replace the cap. Also, if your engine has the canister on the drivers side of the block, there is a horse hair filter in there. It needs to be clean.

Paul, This engine has an after market PCV valve that I believe was installed around 1990 by a previous owner. This PCV system has a hose running from the oil cap filter to the air cleaner. Another hose from the PCV valve located on the valve cover to a vacuum port at the rear of the Carburetor (Carter original) However the road draft tube was never blocked off. So when I bought the car 3 years ago I removed the road draft tube and blocked it off. I was told that was the correct thing to do with a PCV system. What do you think?

Thanks for you comments - AR

AR,



Are you sure that carb. port is below-the-throttle/manifold vacuum? If not, with the draft tube blocked off there would be no crankcase ventilation or pressure relief at idle. That might result in accelerated sludge accumulation.
