low oil pressure need help

[ford racer]

I have a 2.3 stock rods, pistons, and crank with all new bearings and rings. The head is soild lift with a Johnson cam. the problem i am have is i am only getting 20 psi of oil pressure at idle. I have put a new oil pump new guage checked the bottom of the dist. when i roll the motor over befor with out puting the fire to it i only get 5 to 7 psi. i put the restrickter in and took it out it makes no diff. I am lost need help trying to race friday.

[ford racer]

one more thing i think it is in the haed some where. i have had it on my last two motor and both are doing the same thing. maybe cam bearing ??????????????? this haed has 2years of races on it. thanks hope you guys can help

Definatly could be cam bearings.You should have replaced them when you did the rest of the motor.Aux bearings also.Check the lifter bosses for cracks and also look for any crazy or improper machine work that may have been done to head.If the problem is in the head there is excessive oil bleeding off somewhere.Try removing the valve cover and and crank motor over,look for large flows of oil that are not consistent through out the head.

prolly gots bad pickup tube barrings will give u good preshur cold and bad hot or do u got bad preshur all the time

[ford racer]

it was the cam bearings. i had good oil presure at start up but them fell off. it is now 45 psi at 1800 rpm cold and like 24 psi at 1800 rpm hot. does this sound right for a stock pump? the pressure goes up hit you give it gas. seems right to me. thanks for all the help guys.

[car62]

doesnt sound right to me...i run a melling 86C pump and right at 60 at cold idle and about 50 hot idle

Back from Thanksgiving with the Family,
I think your right I'll have to change the crankshaft, it is a small journal, I have never check the clutch for to much travel. To bad no one makes a full bearing for the small journal blocks? I would like to get a billet crankshaft but they are real spendy !

[boportt]

i gotta billet crank and it didnt make me no faster. i coulda got me a newer trailer maybe a duble wide for what that crank cost

You want to run the turbo pump.

[car62]

says who???

[boportt]

You want to run the turbo pump.

Y? thar aint no diff. i spose u is one of them guys that thinks turbo rods and cranks is better too.

[soonersublime]

Race Engineering says to and so does my engine builder. What the difference is I don't remember but they are supposed to be a better pump. Part #86E if I remember correctly.

[soonersublime]

Y? thar aint no diff. i spose u is one of them guys that thinks turbo rods and cranks is better too.

yeah and 5.7 rods turns your engine into a stroker motor.

The 86E Turbo pump is a better pump. Whether it's a different part then the 86c I don't know, who knows maybe it's one of mellings older pumps that hasn't been made in China and is tearing motors up on a weekly basis by flaking but in the end it's a better part # to use when you buy a pump. Believe me if you want I really don't care.

[car62]

thats interesting,ive been using the 86C for 12 years now and never had any kind of a failure...turn from 7200-8200

Cool. I ran the 86e for 4 years. I moved on to a different class but still enjoy lima motor. I believe the problems w/ the 86c have been happening around the past 2 or 3 years rather than the past 12 years. So maybe it's a problem you haven't had to worry about. Depends on where you get your pumps too. Joe(JBV) has talked about this before but it's been a couple of years since anyone on here has mentioned it.

[ford racer]

it dont sound right to me now. made it a lap and a half then the big bang!!!!!!!!!!!!!!!!
broke number one rod right in the middle of the rod. i must of spun a the rod bearing. i checked the bearings when i changed the pump. sucks for me good for the guy that won the race hahahah. thank for the help guys

need a new bottom end now any one got any for sale

[that dude]

Well I don't know what difference is yet in M86C and M86E, but i do see one is priced $10 higher than the other and one weighs about a hundredth of a shipping pound more:)

And I've done searching and see that the 86c fits on pintos, the 86e fits on t-bird turbos, and m127 fits on mustangs. now this is just what i'm pulling from parts stores info, so don't kill the messenger.

I'd like to know on the side, since the pinto was a front sump motor and the mustang is a rear sump motor, are the pickup tubes interchangeable between a 127 and a 86?

[soonersublime]

Doesn't say anything about the 86C but here is where raceeng.com has recommended the 86E

http://www.raceeng.com/techsheets/2300%20short%20block.pdf

I will go to the parts store and see if I can look at both tomorrow and see if their is a difference.

[that dude]

I'm using the M127 pump with the pickup tube that came stock in a ranger I believe.

If I swapped over to a M86E the next time I build another bottom end, Do I need a specific pickup tube just for an 86E?

[spottter57]

both m86c(stock) and m86e(turbo) are standard volume and standard pressure however they are rated differently. m86c: 32 psi at idle, 54 psi at speed. m86e: 32 psi at idle, 60 psi at speed.

[soonersublime]

You run the pickup tube that is compatible with your oil pan.

[grydergeyer26]

Hey having a simler problem. With my motor. 60psi at idle wehn u but a new pump on it no matter what pump it is then when the oil warms up 40 psi at idle then the next the next day or week or when ever the next start up is it only get 40 psi cold and 20 hot but the thing is. After the second start up the psi doesnt go up when the engine revs up?

bearing clearances

[14flower]

ok well it never had that problem befor until i but new rings in it. cuz the cykinders got washed out and jacked up my rings. so could it be my torque settings? guess ill have to ask the machinest that line hound it and sized the rods? or do u just use the normal specs? stock main bolts and arp rod bolts

[Dan32]

86 e great choice we have run them for years!!

[Dan32]

jared u have clerance problems!! are they all new bearings ?? and are they the right bearings?? [standared, 10 under or so on]

[56Racing]

Is the oil plug in the back of the cam?

As far as interchanging oil pumps and pick-ups, you have to use m86 pick-up screens with m86 pumps and m127 pick-ups with m127 pumps. The oil inlet location ( where the pick-up bolts to the side of the pump ) are differant. If you interchange, the pick-up will either hit the oil pan or it will be too far away from the bottom of the pan and the engine will starve for oil.

[14flower]

yes the bearing are all the right size like i said all we did was change rings and yes all the nearings are new well mins the 5 races they have on them so still new. this engine was fine befor. we but the same pan on it and pump and tube.

u didnt put a new pump in it!!!!!?????:eek:

[Foghorn]

Flower. Aren't you the same guy that keeps breaking flywheel bolts? Reading your posts on the forum here leads me to believe you don't know what the hell you are doing. Get some help from someone that knows something or you are going to spend all your racing days on the trailer instead of the track. Get help.

[14flower]

no the flywheel problem was torqe wrench was way off! at 60 ftlbs it was 25! and ive buit alot of lima motor ya im not a well known builder but my (not a nice word)(not a nice word)(not a nice word)(not a nice word) gets it down. and all these problems are on the same engine yet we have 10 other and they dont thats why im on here asking help.

and dan yes it was a new pump but the same pump.

[Boome58]

I think you check if the oil if it there has dirt on it or the tank can be dirt. And Check also the wiring where it goes. Before using some pump.

[Headhunter]

Is it possible you put a rod cap on backwards?

[14flower]

idk ill see tomarrow when i strip down the motor
