just finished putting my gsr motor together..its a gsr block with pr3 pistons and new rings and bearings and a gsr head ported,valvetrain and stage 2;s..now at first i was getting a code 22 for vtec pressure switch..checked that out and everything was good and within spec then noticed my oil light flicker once in a while...any ideas??oil pan looks good no dents..maybe oil pump?pick up?...any ideas???

 

the lack of oil pressure will be the cause of the vtec issue , but yeah did yoiu replace the oil pump and pick up? and did you put the gasket between the pick up and pump, and also the o ring in the oil pump?

 

Are you sure theres enough oil in there? Check your oil level via your dipstick.

nah i used the oil pump that i had laying around!hah....but theres oil up to par with the line and all gaskets and o rings are there..might be the oil pump though..ima have to pull it off..but is there anything else that might cause low oil pressure?

 

What pump did you have laying around that you used?

 

Low oil pressure light comes on at 5psi, I wouldn't be running that engine until you figure out and fix the issue. Are there not specific vtec oil pumps, what was the pump you had laying around?

 

it was a obd2 gsr oil pump.....

 

switched the oil pump/pickup with new ones..and still have the same problems.......what else can it be??anything in the head??

 

i had the same prob...i did a oil change...and i was striaght...as soon as it wud be time for v tec...car wud die basically...do an oil change

 

well i just did that 2day when i pulled off the oil pump/pick up....so idk

 

well thats really weird...i had the same prob...just did a oil change and i was straight...

 

well thanks for the input!i needa figure this problem out though!

 

make sure your pickup isnt bent or the screen isnt clogged

 

i checked that today also when i replaced pump/pickup.........

 

When you started the new motor did you put vaseline in the oil pump gear to help it build oil pressure correctly? Also, are you sure you have the correct size bearings and rings?

 

i'm not sure but isn't there little oil jets in there as well? maybe make sure they're all still there and clear.

 

yeah i second that you should put vasaline on the oil pump gears so an airpockect does not develop, creating pressure in the oil pump which in turn does not allow oil to pass. but if thats not it i would take off you vtec solinoid and check the screen in there for any blockage. maybe pour in some of that motor flush and run the car see if you had some gunk built up in any passage way in the block or the head. make sure all you rubber o rings are in and not cracked on the the head. or anything that has to do with vtec.

 

ughhhhh, ughhhhhh why don't you hook up a analog oil psi gauge to your oil psi switch port?
your probably looking at a psi switch or wireing faulty

 

what were your bearing clearances like? and what kinda bearings did you use?

 

nah i didnt put vaseline on the pump..didint know about that trick.......so i just spread it on the gears??

 

yea ive been trying to look for one to buy...not sure where to pick one up at

 

yea the squirters are in there

 

well the only thing i didnt put together was putting the bearings in and rings..local shop dnr performance put those in and checked all clearances and gaped rings....so im hoping there isnt a problem because of the bearings cuz i know if there to loose u can get low oil pressure

 

also when i got the head back from the machine shop it was missing a small copper fitting with a allen head that sits on the left side of the head close to the water neck on the block...so i plugged it up with a bolt since i couldnt find that exact fitting..does anyone know what thats for?
