Search results for query: no oil pressure

First assume we have a properly working gauge. Let’s also assume the inlet side is not sucking air. Oil pressure is low at idle because the pump can’t move enough volume to build resistance to flow. Why? Thin oil, internal leaks from sloppy lifter bores, large bearing clearances. Shimming the...

I've always thought that adding a zddp additive to oil was overkill and maybe even harmful to oil that was already formulated for a reason. This article/thread proves that adding zddp to any oil can deplete the amount of pressure that the oil already had in the original formula. (I copied just a...

It's a great picture. Remember, these cars needed maintenance back in the day when they were new. Ten thousand miles was a bunch years ago. You're all good!!

‘This’ problem I guess would be the oil pressure dropping when I’m driving after a while. I guess I assumed it and the stalling when first starting up were related because they started happening at the same time. The other stuff I said was just info to maybe help inform a guess as to what could...

There's no telling how many oil filters, all brands, I've used thru decades of tinkering and never had one kill the pressure. I hope you get a chance to cut all 3 apart and find a cause. Glad your running.

All I did after 23 years of sittin' was to fill the crank- case and spin the oil pump. 50 lbs oil pressure. Most of the assembly lube on the cam had since dried up, settled to the bottom of the pan, with no affect on the lifters. The bottom surface of the dipstick showed just a little...

I WOULD NOT use an adjustable high pressure relief valve in the oil pump. It is a standard MELLINGS/Mopar high volume pump with the relief valve spring for that specific application WITHOUT any shims to achieve my results. My operating specs are determined by bearing clearances and oil...

That oil pressure is a bit excessive. No need for more than 60 psi oil pressure tops. You'll be cutting grooves in bearings with that much pressure! Just my 2 cents. ruffcut

The Coronet has about 300 miles on it since the restoration. I think the oil pressure seams funny to me? It has a plumbed oil pressure gauge along With the stock light. Engine was professional built and Dyno run before install with no issues that I know of. When I fire it up cold it seem like it...

You said flat tappet. I'm taking that to mean a solid lifter flat tappet cam to go along with the adjustable rocker arms. These setups use special pushrods as well. ALL flat tappet cams will be "noisy". It's the way they work. What are you running for clearance? Are you setting the...

FYI.....on a GM/DDA 8V-92T diesel engine, which suffered a head O ring failure contaminating the lube oil, GM recommended the use of a compound called BUTILCELLOSOLVE ADDED to the oil, approximately one guart, to absorb and neutralize the effect of the ethylene glycol. Change the oil and...

Valvetrain noise won't change with load. Are you sure don't have an exhaust leak at the head? Generally a exhaust leak makes way more noise under load. Easy to check. Get a piece of small hose. Have someone brake torque the car slightly. Listen by placing the hose around the exhaust/head juction...

Pulled Intake found one pushrod off the lifter and lifter in bore but not necessary staying down in bore during running. Turned engine over with starter after pushrod and lifter installed properly no large amount of oil coming from lifter bore upper or lower turned until see 30 lbs on gauge and...

I have one needing rebuilt. Where can Inget the parts. Tried to send it off a year to a shop to rebuild but was told parts are not available. TIA

Easy way to tell. Screw an oil pressure gauge into the governor pressure port in the tail shaft. Run the car in gear (can be on stands). If you see little or no pressure you have a governor/governor seal ring issue. Pressure will roughly mimic vehicle speed with a 3.23. More gear ratio will...

I thought that was a great recomendation! It was legal...here in WI until around '73-'74. I quit when I started trucking in 1972. I only worked for the dealers and auctions...not anybody off the street Those different times... I recall my boss from Dallas Pat Cockey. I worked for him at an...

No pcv on this one, with only one breather in passenger side valve cover. You'll notice the valve covers are taller than stock, and the breather side has baffles. There is zero oil "mist" on top of the valve cover. There is almost no vacuum at hard acceleration. (the pcv valve ain't doing a...

Maybe you are missing an oil passage plug. If you have oil pressure, you will feel the drill load up and want to twist out of your hand. No, it is very unlikely that it is because of a bearing

Mm, you may be right, but not gonna mess with any internals at this time. It runs to good, and reliable, still pushing about 60 on oil pressure when starting, and would get in it, and drive Coast to Coast, with No worries...

This is what I’ve learned though my readings. Now Im not a scientist or anything fancy just a guy that reads. If your depending on the zinc in your oil to protect your flat tappet cam, your looking at your oil backwards. Your first look should be looking at your oil’s ability to retain an oil...
