sounds like piston slap........

 

so... today we installled the oil cooler and the presurre is: idle 20-25psi, at 3000rpm only 48-51 psi.

I REALLY NEED THE HIGH VOLUME OIL PUMP :-( Can you help me, where can I find it?

btw. VTEC not run

and you have true, Its looks on piston slap, maybe piston pins :-/

 

and btw. is the piston slap destructible for the engine? I mean, if i can drive slow with this damage, im affraid of cylinder walls, that they will be scored

 

Try not to put that 20W60 weight oil in. It's totally not recommended. That's _not_ how to fix low oil pressure. Looks like there are other problems to loot at first.


Seems like there's an opinion forming here about the pistons. You need to look at that issue first. While doing it, take a look at the oil pump. If possible, take it off, re-measure it, all clearances, wear limits, etc., according to the repair manual. Maybe your engine needed a rebuild because of bad oil pump causing oil starvation, and ruining the engine in the first place. Just my theories.

 

We changed the oil yesterday for Motul V300 10W40, and still same problem.

The oil pump is new, but I red, that still problem with low oil press have many peoples here.

I mean that oil pump is in good condition, but we disconected oil relocation filter and turbo, oil press was 80psi-85psi.

have someone experience with this pump??? They make HV oil pump only for AP2, but I tahink, that pump is same.

Thanks!!

 

are the valves adjusted within spec?

 

The engine sounds noisy. I was just making a guess about the pistons but it sounds like the engine is a little loose. You know low oil pressure could be caused by bearing clearances within the engine as well. You all didnt run oversize bearings for rods or mains did you?

My old miata with a built engine always had lower oil pressure ( it was built loose ) which is what you want if you beat on the car a lot because if its loose when its warm its tight make sense. Anyways, I would also adjust your valves as well and check to see if they are out of spec. If I recall exhaust is .10 and intake is .09". Might wanna check on that. Also wiseco isnt a piston I love since it slapped a lot on my BP miata engine...that could be what you hear. Good luck man.

 

03BlkS2k: yes stock clearence

AndyFloyd: yes you have true, problem will be in bearings, main or rod, they leak oil press. We must rebuilt the engine :-( The noise is from TCT, cause o low oil press.
