Hello,
I got an issue under my valve covers i have oil out of all the pushrods on passenger side and no oil out of any on the drivers side. Mind you this is a fresh rebuild and i have ran it for some time now and figure the lifters would eventualy build up. find it odd though that one side is good and other side has not one drop other then from me putting oil in filler hole. My question is is there a oil feed for each side of the lifters? Maybe a galley plug was missed by the machine shop. I have tried a new pump, changed rod bearings again, tried mechanical guage, i will say my pressure drops to about 10psi when truck gets to 195* norm running temp. Oh yeah by the way it is a 5.2 318 in a 1999 ram 1500 sport 4x4. Thanks in advance.

 

i'm not sure about your problem but did you have to lift the engine to get the oil pan off? i've heard mixed answers about it.

 

no just had to jack up frame and set jack stands under frame so the axle would hang lower

 

awesome, now i know that my rear main seal won't be too tough to change.

 

any ideas on my prob

 

Did you start the motor with the VC off to confirm there is no oil? I could see 1 or 2 lifters not pumping up, but if the whole bank has no oil, then I would think it has to be something clogging the oil galley. Of course that would not explain why you only have 10lbs of pressure.

 

Yes i did remove the vc to confirm. I also tried blowing air in the hole for oil psi sending unit i seem to have air coming out but not alot. i do have 40 psi at start up but once i reach 195* it drops to 10 psi. which the oil thins as it warms. Im thinking when machine shop did the work they left out a galley plug somewhere. Cuz in my opinion i should have more then 40 psi on a new rebuild on a cold start. Napa did my work as it is they gave me .010 bearings for my c-rods and were supposed to be .030. does anyone know if there is a plug under the oil filter adapter plater that may be missing? or anyone have a good pic breakdown of a 5.2 that i can look at to see oil flow and passages? Im getting really po with this damn engine rebuild.
