Then oil circuit on right bank of cylinder block is clogged. Therefore no oil on camshaft & hydraulic lifters of right cylinder head. The clogged circuit could be inside cylinder head or inside cylinder block. First time remove right side cylinder head out from engine, then turn manually crankshaft in clockwise direction. If oil flows out from cylinder block on the right bank of cylinder block, clogged oil circuit is on cylinder head. Allways you must clean properly cylinder head oil circuits! If no oil flows out from cylinder block on the right bank of cylinder block, then clogged circuit is inside cylinder block and must be cleaned !!!

    Yes, of course you can try this before cylinder head removing !

The head cylinder galleries are clogged up not letting the pressure to flow in this head. How often was the oil changed on this engine? If once a year that is not enough.

What does base circle area mean when doing a valve job ?


Base circle is the camshaft lower diameter where the lifter rides before the lobe starts to come into play.
The Lost Art of Valve Adjustment
Your second question depends entirely on the engine in question.
On a pushrod V8 the oil usually is metered by the valve lifters and goes to the rockers through hollow pushrods; a few drops of oil are released by the lifters during each valve stroke. Until full oil pressure and warm oil are in all of the oil passages, the oil to the rockers will be less than that of a warm running engine. The rockers really don't need huge quantities of oil, it is a lot harder to get oil to the valve stems.

You may want to make sure you have good oil pressure and the valves are properly adjusted [even on a hydraulic lifter system there are limits to how much the lifters will self adjust].

If you have an overhead cam engine, you will need lots of oil on the lifters and cams.

How do i turn the lifter in the right place if i did not take it apart?


It technically does not matter because even though there is an oil hole to one side of the lifter, the oil gallery in the lifter valley pumps oil around the ridge in the lifter. Standard hydraulic lifters can spin anyways.

Roller lifters should be installed same lobe and roller direction. If not sure install with oil hole facing rear. (oil pressure from this direction)

Technically if reused, all lifters should be installed back on the same lobe...if possible. You'd probably be ok with couple unknowns if engine in overall good condition. It's just with a very worn engine and valve train combined with very low oil pressure, switching lifters around could create a condition that could "wipe" a lobe on the cam and a valve could cease to lift.

It's also a good idea to soak clean lifters briefly in oil (until air bubbles gone) to assist in initial valve train pump up.

Hope this helps.

Hi. I can give you a simple, but time consuming test to do to check your intermittent compression problem. New hydraulic lifters cause a lot of problems until its settled. Remove the camshafts and the hydraulic lifters. Take each hydraulic lifter and put it in a vice(becarefull not to damage them) and squeeze out all the oil in the lifters. Then put them back and replace camshaft and allign timing marks. Check compression ratio. What happens sometimes is that the oil pressure is too high(stuck oil pressure release valve or cold thick oil) and this causes the oil pressure to put so much pressure on the hydraulic lifters, that it slightly forces the valve open. That will cause your low compression as well as backfire through the intake.

Engine lifter noise


Typically lifter noise indicates loose or broken components. Pull the cover and check for damage or lifter play. Follow the factory procedure for re-setting your valve clearances. -----------------------------------------------------------------------------------

If the oil pressure is good, likely you got dirt into a lifter while you were working on it. You can take it apart again and clean out the lifter, or add marvel oil and if the stuff that got in there is carbon and not sand etc, that may dissolve it, or replace the lifter. If I were to go through all the work of taking it apart again, I'd opt for a new lifter, Also make sure that the rocker and pivot aren't worn or you may be wasting your time there.
Never re-use a lifter unless it came from the exact location it had been installed in, and then, only on the same cam it was used on. lifters once used, establish a wear pattern and will ruin a cam very quickly if replaced out of order.

Oil pressure is fine. Oiling only to the pass side valve train.


The 3.1/3.4 engines are built the same way. The oil goes through the cam bearings then to the lifters, then the push rods to the rocker arms. The last engine I seen that had a weird problem had the cam bearings spun. Unfortunately there is no easy way to check for this problem short of disassembling the engine.

The other possibility would be bad lifters but loosing half of the engine lifters wouldn't be possible. Sometimes the pushrods wear on the contact areas also but not usually half an engine.

This isn't going to be easy, Good luck.

the lifter noise might have been a bearing going bad or a piston ring. if you lost power you probably lost compression on one cylinder. Try checking your compression with a compression tester screwed into your spark plug socket. here is a site with a procedure.

7.3 liter will not start.


yes they are you stated that you have mech oil pressure did you install a gauge?. this is a fuel line pressure sensor on the right bank at the frt of the head this sensor is rail pressure that high pressure oil pump creates check you pressure there that will elimnate that head the other side is a little more of a pain to test. one other thing to keep in mind is that the cranking speed is very important, and have you checked the oil level on a 7.3 deisel if you are more than 3 qaurts low on oil you will trap air in the high pressure pump. this will cause a hard start our even a no start
