don't see it often, but the pressure relief in the pump likely is gummed up.
Sometimes using a very good engine flush like the one made by Amsoil will dissolve the crud in there and restore operation but most times you will need to replace the oil pump.

It happend to me a long time ago on a 454 in my 71 chevy picup, there is a chk. valve on the oil filter housing where your filter screws on that is not working or stuck open and letting to much pressure thru. It happend to me 2 times in a week until a friend of mine who had his own shop told me to chk. that valve and thats what it was. I just took it apart and cleaned it up and maid sure the chk. valve worked and put it back together and no more problem.

Hi please can you help ive recently overhauled the the engine on my 2l opel rekord 1986 model but for some reason it keeps blowing the oil seal on the oil filter on start once then during idling once.

full rebuild with bearings, rings, head ,referb ,new oil pump
or partial rebuild re ring ?

filter issue wont be because of rebuild or higher oil pressure

try filling the filter with some oil before fitting
are you smearing the new oil filter seal with new oil before fitting
and is the surface of the face where the oil filter spins smooth no scratches or gouges or roughness

if the seal is intact you can use silicon sealant
to get it to seat and not leak

are to putting the filter on too tight or not tight enough?

spin till contact is made to block
and hand tighten only no filter tool
run motor and if leaking tighten one third turn more

if you use the tool and screw it on heavy
will flatten the seal and
you may need to cut the oil filter off next surface

96 Ford Ranger 2.3L ticking sound. Comes and goes. Puff of white smoke coming from exhaust only on initial start up. Slight rough idle.

The noise is lifters, the smoke is valve seals. This engine is showing signs of wear on the top end.

I have a ford transit van I keep losing loads of oil from the bottom of oil filter why.

there are a lot unanswered questions in your description here, but I will try to give you a few ideas.
when was the oil last changed? is it leaking from where the filter is attached, if so filter needs to be removed & either put back on or replaced. be sure before installing new filter to wet the filter gasket with a little new oil before installation, this helps with seal.

is there a hole in oil filter, if so it needs replacing.

is the filter on front or rear lower portion of engine? check to see where oil is coming from, it may be a front or rear crank shaft seal. which is a major project.

keep in mind that when the engine is running & also when vehicle is in motion the oil will be blowing back & occasionally make it look like the oil is leaking from somewhere else.

if you start by getting under vehicle ( make sure vehicle is properly blocked up so no chance of falling on you. do not trust the jack alone to hold up vehicle) and try to look & see where the oil is coming from.
there only certain places that oil can leak, gaskets, seals, line connections ect...

Why does my cars lifters make so much noise when i first start the car?

this will be from , incorrect oil filter ( cheap units are missing a non-return valve which keeps oil in the lifters), wrong grade of oil ( viscosity to low for the wear on the engine go up to 30w-50), worn lifters (replace), low oil pressure in the system.
Most lifters that have seen some miles will rattle for up to 10 seconds until the oil pressure builds up but any longer and I would consider replacing them

1990 5.8, 74000 miles well maintained. Oil preasure drops off

Why are you running 10 - 40 weight oil. You might want to rethink this. As the miles go up the ware on parts goes up. So I would recommend a 5 - 20 or 5 - 30 high mileage oil. If the oil pump is that new and working properly then this will help with the pressure.

Oil pressure light beeps on and off before and after new oil pump

Have you replaced the sending unit for the oil light yet, do that now and that will likely fix the problem. The sender will be near the oil filter most likely.

Have a 96 buick regal with 3.1 ltr engine. The oil filter keeps blowing out. Put a new one on it and start it up and within 5 sec the filter has bent and blown out the seal. I have never seen this before...

Maybe have the system flushed out at a "Lube pro's" or something. If its blowing out the filter, id say something is blocking the flow of oil after the filter. Just a guess

bad lifters or at wort push rods wearing out try putting 10 40 oil instead of 10 30 since it has high mileage if that does not fix it it is either the rods or the lifters simplest thing firt have lifters checked out it may be a loose lifter
