Ok, so heres the story. I just got my car boosted, and tuned. Its a 94 integra LS. Made 227 on the dyno. Really reliable. Anyway, last tuesday night i was on my way home, and as i was coming to a intersection, my oil light came on, and i thought maybe a oil line came off or the oil was going somewhere is wasn't supposed to go... As i took off, it started to blink, and i looked at my guage, and there was no pressure at all. I was about 1/4 mile from my house, so i limped it home (I know, really stupid, but again, at the time i thought a return line broke or something, i didn't really think that i had NO oil pressure)
Anyway, it was late at night, i looked under the hood, no oil anywhere, just a little oil coming from the BOV, just like a drop.
In the morning, i went out and started up my car, and the oil pressure came right up.... So i changed the oil and filter thinking there was a clog or something.
I drove it around a little, and it seemed to be running fine at first. After a little, the oil pressure seemed to get pretty low at higher speeds, i brought the car home, and the motor was staring to knock really good. I got my scope and listened to where it was coming from, and then my car just shut off........
Tried to crank it over, and it barly turned over once...
So now i know it spun a rod, and it possibly ate into the crank now too...

But any ideas?? Something in the oil pump?? All i can think of is something happened to the oil pump... Any thought on what i should look at/look for would be great.

In the mean time, anyone have a new B18B block for me???

 

did it BURN oil?

no, it didn't. As i drove it around the next day, it didn't smoke at all, and there was plenty of oil on the dip..... I checked the oil tuesday night, and it was the same as a week ago, and then when i changed the oil wednesday, it was at the same level, and didn't smoke at all, but then the car just shut off...

 

oil pump, or you dented your oil pan and blocked off the sump. those are my guesses.

 

oil pan is off a b16 motor, and mine is a b18b motor, that wouldn't matter, right? The oil pan is not dented at all.
Yea, all i can think of is the oil pump is taking a crap. Only other things would be a clog somewhere, or a collapsed oil filter... which i don't think would really be a problem. The motor has 230,000 miles on it, so oil pump is my first guess.
Im ripping the motor apart right now to see if the crank got messed up or not, cause then i might be able to just put new bearing in and be fine... but the whole having no oil pressure that night still scares me, and i think i might just want a whole new long block.

 

lesson learned, no oil pressure, no motor
most times its the best to just go find a new crank and not deal with problems of undersizing it

yup, both my brother and i have built motors, and we are still thinking how dumb we are for driving it... But i think ill just be putting in a new longblock and not deal with all the problems of everything, cause with it having high miles, who knows what else is wrong, and if the oil pump is bad, the amount of time it would take to put a new oil pump in would be just as easy to drop in a new motor.
Anyway... I dropped the oil pan tonight......... Take a look at the pics!!! The screen on the sump is so clogged... which could easily of blocked the oil. LOOK:

 

the second picture is a pick-up magnet that i just moved around inside the sump gently, and wow.... there were some bigger pieces, look at the third pic. From looking in it a lot, it almost looks like a ground up penny was in the motor...

And if there is this much crap in the motor... I don't think i should rebuild this motor to begin with.. I did put a crappy STP oil filter on with the mobil 1 syn.... which probably didn't help the situation much.

 

mostly everything you find in the oil pick up is from what you did to the engine, as in all those parts are engine bearing pieces that you destroyed; that is most likely not the WHY it happened...

all seized bearing engines WILL have a lot of metal and chunks of **** on the oil, oil pan and in the oil pick up mesh.

yea, that is true. I didn't think it would all get clogged in there that fast. There were a lot of other things in there though, besides metal. Like paint chips and such. But then that rules out the sump being clogged... so think its the oil pump that went out then? But then why did it work fine the next morning?

 

The reason I switched to the ricer from my 4D is I started to see a constant 25PSI of oil pressure... and sometimes 10-15.

As for the rest of the problem: I did a fresh oil change with a K&N filter, and what do you know... 60PSI initial start-up, and then quickly back to 25, once warm 10-15. I knew I wanted to park it right then and there.

Time for an oil pump and rebuild. Good thing this D15B had a guage on it so I didn't spin a rod bearing.

 

15psi at idle is normal

the pump probably broke, its common to get erratic pressure when the pump breaks in one or 2 pieces.

 

i would say the pump gear broke

i have a built short block if your intrested lol for sale

 

not to thread jack, but are those after market oil pump gears even worth it?

if you weren't so far away... I would pick it up asap. Im still trying to find a local motor... no luck. And i just got the motor out of my car not more than 10 min ago..

 

Ok, so I used a b16 oil pan from my friend (off this 99 civic si) on my b18b motor... that shouldn't have anything to do with the problems, would it?
Im still using the b18b pickup and windage tray... I might of heard that i should be using the b16 pick up and windage tray if im using the b16 oil pan... Is this true?

honestly how much is an oil pan? if there is any doubt then its worth the money for peace of mind.

i had a b16 and ls oil pan side by side a while ago. i dont remember exactly but there was somethting going on that made me use the ls oil pan on my ls rather than the b16 cuz it was in better condition at the time

i work at autozone, and i just called there, and looked up a oil pan for a 94 ls, and for a 99 civic si, exact same part number, but im gonna put both oil pans side by side and really look into them both and see if there is any problem. The car ran fine and was tuned on the dyno with the b16 oil pan though, and drove it 45 min each way to the shop, and then drove it for 2 weeks... so i would think that the oil pan would of caused a problem from day one if there was a difference.

 

well, new motor is in now, and the oil pressure seems to be way better than what the old motor ever was. The old motor never was at 50psi at around 60mph...

im thinking my old motor has oil pressure problems way before i even put the turbo on it, the turbo just helped it go a little faster. But i haven't ripped it apart at all, but im guessing that the shaft is broke or something.

but anyway... anyone want to buy a b18b longblock?? haha. needs a new crank, new bearings, and possbily a new oil pump...

 

I never saw 15PSI at idle untill just before I parked that car; and certainly never saw a max of 60PSI when cold-starting after an oil change/tune-up.

Granted: 15PSI idle may be fine, but it shoudl travel at-least past 40 if not to near 60 when you give it gas.
