hey guys

im in very sad state of mind after waiting almost a year to get my car on the road iv got a major problem

ok here i go, i had an r33gtr which had a forged motor with a n1 pump, i put the motor into a r32 gtr

all way going well until a couple of hours ago, after my mate finished adding the final touchs to the pfc we took it for a drive got a bout 300m down the road, and the car stalled, tryed to roll start (kick the clutch while moving) all 4 wheels locked up.

at this stage i was very worried, it felt as if the motor seized mind you the motor is only bout 2800km old built by race pace...

so we pulled of the cam and cam gear covers of to see if anything broke,

but nothing but i did notice there wasnt allot of oil on the cams and underneath the cam covers was dry as a bone, so something to do with oil pressure,

i do have any aftermarket apexi oil pressure gauge that wasnt showings any sign of low oil pressure. and didnt here any knocking or breaking sound

the motor was running perfectly in the r33gtr which i use to own, now is a wreck coz it got hit but no where near the motor, i did get a breaker bar and crack the motor every few week to keep everything lubricated, only thing iv changed on the motor since it was in the 33 are hks dump pipes, bigger exhaust, changed plugs,oil and filter

oh and btw my mate is a mechanic and know what his doing when it come to rb26s and will try and get it stripped down tomorrow but i need to know if this has happen to anyone before im very worried and need to sleep at night

some please help thanks guys

mods to the motor are

Forged Pistons (Arias)

-Metal head gasket

-N1 Oil pump

-ACL bearings

-New crank

-Head Work (just general tidy up)

-New belts

-Engine Blue Printed

Does it turn over on the starter with the plugs pulled?

Does your fuel pump prime on ignition?

You have spent a sizable chunk of cash on your motor, why not take it to someone who knows what they are doing before pulling the motor? :P

no the motor dosnt turn over at all, not even with a breaker bar, and my mate is a mechanic that knows what his doing, not his fault engine was running mint for bout 10mins then all of a sudden seized up and locked up all four wheels,

engine is getting pulled down today to find the problem

All injector seals in? drain the oil?

I have no honest idea but I read the other day a person having the same problem with injectors which are not installed correctly and was flooding the engine?

Hydrollic lock i think its called

Edited by DECIM8

im over this car, i was so close to stripping it down and selling it as parts,

but my mate didnt have time to pull it apart today but will early next week, but looks like i will be folkong out for another build,

but the funny thing is we never hear nothing break, and also no metal shavings when we drained the oil

it might seem like a dum question, but when you started for the first time did you take the oil cap off and make sure the cam lobe you can see from there had oil on it????

was the correct seal used on the N1 oil pump?

cause if a breaker bar wont turn it over you have either got A: a siezed motor B: a dropped valve or C: dropped a big end cap?

but from what you described above i wouldnt be surprised if the main bearings have spun and it the cradle pressure clamping the crankshaft.

good luck with that one bro, i feel for ya...

atleast when mine stopped going you new what was wrong with it cause number 3 piston was hanging outta the block.

for it to sieze solid and not make noises, it will of spun a main bearing. the cambelt will snap at the wieght of the whole car. if its just the head siezing, its a pretty damn strong belt!!

so no oil in the head.. all of a sudden. somethings blocked. does it have an oil cooler with remote filter?

the belt isnt snaped, i dont have an oil cooler or remote filter but i did notice there was thick gunk underneath the cam covers but not really any oil there, from what i can gather i think the oil pick up is blocked but wont no until we pull it apart,

if the main bearing is spun will it of damaged my crank? or will i just be able to replace the bearings?

anyway thx for this guys im pretty stressed out atm

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
