Are you running oil restrictors? Have you looked over the lifteers and made sure that the oiling oils that pass through them are unrestricted? Are you sure that the lifters are getting into the blocks oiling passage ways? Have you inspected all of your pushrods to insure nothing is inside them that may block oil flow through them?

I check pushrods they are clear.I guess my next step will be to pull intake and check restrictors and lifters.thanks for the reply and help.

What size restrictors are you running?

don't know yet.once i pull intake I'll let you know..thanks

I don't like running much restriction to my upper end. As an example. On the stock SBC blocks. I don't run the 0-ring on the restrictor and I drill the holes out to about .090". So I'm restricting a little. But not enough to even come close to having problems.

Not to sound like captain obvious, but did you put in the oil galley plug behind the distributor, believe it or not I've seen people overlook this one.

I wondered about that myself. But I've not worked with this block. So I didn't ask the question.

we use no restrictors, sounds like you installed a plug in a lifter galley hole by mistake. The mere fact you have oil pressure down bottom proves all plugs are in. If you left one out, you would have very low op. Check the front lifter valley inner plugs to the cam galley, they might be in!

here some more history of the car.I bought this 91 mustang last year from a person from dearborn heights MI.the engine was built by livernois motorsports.I discover oil problem when I was setting the lash.it's a dart iron eagle block 351 punched and stroked to 396 14:1 comp, peterson external oil pump,canfield 58cc racing heads,950 holly,supper victor intake,danny bee belt drive,crank trigger,nos fogger,2 speed powerglide.I'm going to pull intake manifold and check restrictors.going to rig up and run oil pump without engine running to see oiling with intake off.problem may be with lifters.lifter bores may need to be grooved.thanks for all info guys.

canfield 58cc racing heads!!! :eek: Why,.... there's your problem...lol Just kidding.

Before you had bought this car. Had it been raced at the track? Did the have any problems?

When you were running the valves and discovered the problem. What tipped you off to the problem? Was it abnormal wear? Some kind of scuffing? Or just no oil to the top as the engine is being turned over with no fire to the ignition? Is this a true dry sump system or a wet sump system with external pump?

Since it's an external pump. Have you checked all the lines for blockage? What oil filter are you running? Is it a quality racing filter? I've seen engines have good oil flow, then change the filter and have no to very little oil flow. So in this case, if you aren't running any kind of filter bypass system, (which I prefere), and it is a filter deal then you wouldn't have much, if any, oil flow. How long had it been since this system has last had oil flowing through it? Had it been primmed before you tried using it? What oil are you running? Have you inspected the gear belt at all? I have seen teeth missing which leads to slipping. Which leads to flow losses. When was the last time the pump was inspected. I had a circle track guy bring me an oiling problem once who ended up having part of a valve spring shim end up in his pump some how. It caused something like this. Nope,...he wasn't running any screens in his suction line fittings. :rolleyes: He does now though.

Instead of grooving the lifter bores, I would consider the lifters. They are more replacable if you mess up a bit and a ton easier to do. Just flatten out some of the area between the main oil passage of the lifter and small oiling hole of the lifter. This allows for oiling for a bit longer. This has been around for quite a while.

I have a stihl 010av 2 stroke chainsaw with a 14" bar. The other day I noticed it wasn't oiling the chain as it should so I stopped it and investigated. Eventually I found that the little valve under the diaphragm in the oil pump had become blocked and so cleaned it out.

I now have the reverse problem. Oil now seems to pour out much too quickly from the little tube, such that the chain cannot take it away fast enough and it drips out of the bottom of the saw when running, even at tickover.

There is a small brass insert pushed into the end of the oiling tube where it emerges to oil the bar, I have found in the past that this needs to be crimped to various degrees to slow down the flow, however, this time no matter how small I make it, the oil just seems to flow out much too fast, about a drip every 2 seconds or so. I have run the saw without the bar and chain to make sure that the oil is not leaking from elsewhere and the only place it is coming from is the little tube as it is supposed to. Have you got any ideas? There doesn't seem to be any form of flow adjustment.

Many thanks

ok men this is what I found after pulling intake.rear left bank had .075 thousands restricter and front left bank had blank pulg in it.I rigging up a manual pully with drill bit to turn the external oil pump and the restricter with .075 hole would not let any oil out with 60 oil psi.call dart and talk to tech and he said to run without rear restricter and leave front blank off.pull rear restricter out 1/8" hole now.turn oil pump with pully and now getting good oil all acroos lifter gallys W/ 60 PSI.install intake ,set lifters,fire up engine.getting good oil flow up through pushrods now.when to San Antonio raceway and run car two time.first run RT.3548,60ft 1.81,1/4 mile 11.5 @ 118 mph.second run RT .6247,60ft 1.70,1/4 mile 10.9 @ 121 mph.MAN AM I HAVING FUN NOW!!!! THANKS FOR ALL THE HELP:)
