can a collapsed /stuck lifter cause a loss in oil pressure?

Question

2000 mazda b3000 3.0l engine.. i put a crank kit in it for knocking and new oem oil pump and timing chain.after engine runs about ten minutes lifter noise occurs and oil pressure drops.

Answer 1

No, lifter collapse wouldn't cause oil pressure loss. Sounds like wrong weight oil or something worse.

Answer 2

It could but not likely more than likely your losing pressure because your rings on the pistons are worn down. This is fairly expense fix either you can do a rering kit or find a decent used or rebuilt engine. The collpased lifter will cause valvetrain damage if it isnt fixed soon which means you may need a new head, cam kit, and a valve job. But I do have a small trick for ya to try because I had the same problem with a 2.3l put some ford type f or equilent fluid into your oil. The extra cleaners help with un sticking the lifter.

Answer 3

certainly, it appears like an exhaust leak to me. Lifters have a quite consistent loudness using certainty the engine revs, rod knocks get louder using certainty the engine revs yet are it variety of feels that audible at idle (indoors the video i'm no longer able to be able to hearken to the knock at idle as properly the shown certainty that it may be different in individual). What i'm listening to is going contained in process the steel sound that exhaust manifold leaks could extra of a roar, whilst rod knocks consistently sound like somebody is hammering on the engine, hammering extra stable and speedier using certainty the engine revs. the ideal and maximum low fee way of telling the version between the sounds is with a mechanic's stethoscope, frequently below $20 at many motor vehicle chain shops and a obtainable issue to have around as properly (first source as an celebration). If the sound is clearest on the crankshaft area - there is usually a splash a lip which you would be waiting to get get admission to to on the edge of the pulley - it is a rod knock, if clearer on the surprising of the engine it is a lifter, if no longer clean the two place it is likely exhaust. no count type if it is an exhaust leak you are able to eliminate the rod from the stethoscope to attempt to pin down the area (it is going to be a manifold gasket or a crack indoors the manifold) yet a extra precise way is with a shop vac. Empty the canister, placed the hose on the hollow, and permit it run some seconds to blow the grit out. Duct tape the hose to the exhaust pipe and turn the vac on. you are able to frequently hear the hiss and could surely adventure it as you probe around the chilly exhaust manifold which comprise your hand. the surprising suspect indoors the oil gauge situation is the sender. it is extra ordinary and extra low fee to certainly replace the sender than to do certainly troubleshooting. If the readings regardless of the undeniable fact that dance around it somewhat is time to place a certainly gauge on it (connects to the placement the sender screws in) to be sure no count type if it is a certainly oil stress situation. i do no longer propose highway driving till you have a competent oil stress reading yet even fairly some oil stress is adequate for soft driving.

Take your oil filter off and cut it open. Examine the paper inside and if you see metal flake, you've spun a bearing.
