There seems that no oil is reaching my rockers on one side of my engine it is dry .

can some one help me please as i dont know much about these engines and dont want to damage the engine.i have had both covers off and oil is reaching the other side.

the heads i have are ECZ-G   picture below

the next picture is of the valves

can someone please help on what to do thanks steve

Steve:

What I would do is loosen the rocker stand bolts about 1/2 to 1 turn, and run the engine to see if oil oozes out from under one of the inner stands.  If it does, then the rocker shaft needs to be cleaned of sludge, if no oil oozes out, then the passagway from the cam bearing to the top of the head needs attention.  It will be noisy running with the stands loose, but won't hurt anything.

THANKS FOR THE REPLY I HAVE NOW TAKEN THE ROCKER SHAFT OUT AND TOTALY CLEANED IT , I PUT A WIRE DOWN IN TO THE HEADS IN THE OIL HOLE PUT BACK TOGETHER I STILL HAVE NO OIL ON THAT RIGHT SIDE .

LEFT SIDE OF ENGINE IS FINE.

WHAT IS NEXT TO DO???

STEVE.

Steve, how are you determining there is no oil, is it with engine running. The reason I ask is you may have a cross drilled cam. If you are using a drill and extension through the distributor hole you need to slowly turn the crankshaft and see if you then have oil. If you have tried this and are sure you have no oil you could have a stoppage at the cylinder head. The next step would be to remove that head and check for sludge between the block and head, fairly common if sludge was ever allowed to build up in the engine. Mike

Assuming you have a center grooved camshaft, the center cam bearing may have enough wear that the oil flow to the top is restricted or shut off.  When the camshaft journal groove wears heavily into the cam bearing, oil to the the passenger side rocker bank normally shuts off first simply due to the rotational direction of the camshaft.

 

But one other thing to do before going deeper into the engine is to build a flat plate that bolts to the head over the rocker oil supply hole that has a grease zerk in the plate.  Then take white lithium grease and pump into the hole which may clear up the oil passage under the head.  The dog leg that the oil must make at the head gasket could potentially be sludged up and the grease will force this back down and clear the passage.  You might try doing the same with air pressure but using the grease applies considerably more pressure in clearing the galley.

THANKS TED AND MIKE

IT IS THE DRIVERS SIDE THAT HAS NO OIL

THE PASSENGER SIDE SEAMS TO BR OK .

THE PLATE THAT TED SAID TO MAKE IS ONLY THIN , SO THAT IT SLIDES UNDER THE ROCKER TOWER, HOW MUCH GREASE SHOULD I PUT DOWN THE HOLE AND HOW LONG SHOULD I RUN THE ENGINE FOR

STEVE.

The plate doesn't slide under the tower. You bolt it in place of the tower,the shaft assembly must be removed, and pump grease into the supply hole.

what then start and run the engine.

The plate is going to be at least thick enough that it can be tapped for a grease zerk which means 3/16” or thicker.  I’ve just made them from scrap laying around.  The rockers are not in place and the engine is not running when clearing the oil passage with grease.  It's not expected to take over a dozen grease gun pumps to clear the passage.  On the flip side, if grease pressure suddenly builds to point that no more grease will go into the passage, you may have a camshaft bearing issue.

sorry misunderstood

now know what you mean
