Well, nothing looks out of the ordinary, so it looks like I'll be pulling the heads this weekend to dig deeper.....
Anybody recommend a good head gasket?

 

Hey felton316. Good to hear from you again. I was wondering about your oiling issue. Looks like you have a lot of input this time around. I don't have anything to add. I'd say the guys have covered about every possibility, except the one it is? Sure sound like an oil return issue? Good luck and keep us posted. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

 

TTT

Have you found the problem?

 

Take off the oil fill cap.

Can you see oil up there after you start the car?

If not maybe a freeze plug is leaking? Where is the oil what you have to ask.

 

Hey PSJ, it works fine while idleing and standing still, and I don't have the ***** to check the oil fill cap while I'm driving. It seems to only happen once the car gets moving.

 

this makes me wonder if this is related to all the dealer engine pulls due to knock? Hmmmmm <img border="0" alt="[driving]" title="" src="graemlins/gr_driving3.gif" /> <img border="0" alt="[burn out]" title="" src="graemlins/gr_burnout.gif" />

 

No, I haven't found it yet! I will not be able to start on it until after work, Friday. I've been pretty quite because I just built a new computer, and it took some time to work the bugs out. But, starting tonight I'll begin pulling the heads, and if I find no problems, I'll just keep going deeper until I do. This will also give me a chance to replace alot of the bolts with ARP bolts. So, its not a complete waste of time.

 

Note that oil returning is directed by the crankshaft oil deflector. You may be overrunning its abiliy to return the oil. I think the simple answer is lower your pump pressure/ volume and you shouldn't have a problem.

"Lubrication Description



Lubrication Flow Schematic

Engine lubrication is supplied by a gerotor type oil pump assembly. The pump is mounted on the front of the engine block and driven directly by the crankshaft sprocket. The pump gears rotate and draw oil from the oil pan sump through a pick-up screen and pipe. The oil is pressurized as it passes through the pump and is sent through the engine block oil galleries. Contained within the oil pump assembly is a pressure relief valve that maintains oil pressure within a specified range. Pressurized oil is directed through the lower gallery to the full flow oil filter where harmful contaminants are removed. A bypass valve is incorporated into the oil pan which will permit oil flow in the event the filter becomes restricted. At the rear of the block, oil is then directed to the upper main oil galleries which are drilled just above the camshaft assembly. From there oil is then directed to the crankshaft and camshaft bearings. Oil that has entered the upper main oil galleries also pressurizes the valve lifter assemblies and is then pumped through the pushrods to lubricate the valve rocker arms and valve stems. Oil returning to the pan is directed by the crankshaft oil deflector. Oil temperature, pressure and crankcase level are each monitored by individual sensors."
