Report that engine failure

[RB25SEB]

Hi everyone!

just wanted to ask a quick question, but does anyone have any idea to why my HICAS light comes on when its a warm day and im cruising in a straight line? Im driving a series one r33 gts.

Because you haven't removed it yet!

[RB25SEB]

haha, nah i dont want to, i want to keep it mostly original as possible. and i like the idea of having the 4 way steer. The disadvantage is that she kicks out when in the wet going around a round-a-about lol.

Im sure that's your LSD, the hicas is supposed to correct the tendency to slide out, the rear wheels turn the same direction the front wheels do.

RIP R32 RB26DETT.

You provided me hundreds of memorable 4WD launches, many high speed track events, off street drag days and thousands of smiles from that angry bark and flames when I change gears at full noise.

Fùck you to whoever designed this component:

Hahahah ouch. Any pics of the bearing shells, crank?

Yep,

In line with the thread, I should post:

Engine/Car:

1989 R32 GTR RB26DETT

Type of failure:

Broken oil pump.

Factors influencing the failure:

Right foot and rev limiter.

State of tune of the engine:

It's stock officer.

Suspension and tyres:

Meh.

Oil used and service interval:

Martini 10w50. Third oil change the day before engine failure.

General comments:

About 8-9,000km since I built the motor.

High RPM, dropped the clutch, held it on the limiter until the car got to about 60km/h. Heard a tapping noise, pulled over and turned off the motor. Lifted the bonnet, thought something was hitting the fan, nothing obvious. Started the motor and heard a tapping noise from the bottom front, checked the dash and oil pressure was on zero, turned off the motor.

Shit eh, called towie for a lift home.

Ah thats not to bad. Regrind and oversized bearings all good

Yep, could have been much worse, lucky I turned it off as quick as I did......

[beemae30]

Very much so. Pulled down a Deutz 2011 4 cyl engine today were they left it uncovered for a bit slapped a new head on it and started it, give you a hint crank+rust+main journal = $20,000 rebuild hahahaha

Do you have aftermarket steering wheel?

Could be the sensor.

I have aftermarket steering wheel & I found my HICAS to be a hit or a miss basically, when I was doing my ~400km trip to Albany, at 1st the HICAS light came on after about 1/2 hour of driving then when I stopped for a break (turned the car off) at the 150km mark the light didn't bother to come on for the reminder of the journey.

r32 gtr oil pump failure at just under 400whp. early 32. failed on dyno and was caught at the exact moment, then shut off straight away. bearings rods and pistons are all like new. i could have put them straight back in with a new oil pump and collar. this was a perfect car when i got it, had never ever been modded at all. but one thing i noticed when doing a belt change was how easily the balancer came off. they should be painful to get off was rpm limited at 8000, any stock motor should be 75000 imo. plus i rarely exceed 7500rpm now anyway lol.

General comments:

driving home, hit 3rd gear limiter... started smelling smoke, then started seeing smoke... turned off... quick under bonnet inspection looked ok, started car and the head was noisy, no bottom end rattle yet... after pulling engine found harmonic balancer bolt loose..

EDIT: and since everyone else says there limiter, mine was at 8250 and hit it maybe 20 times a day... no working tacho in silvia and wheel spin = limiter bash lol

could just be a dodgey reading from the sender. have a look under the oil cap to see if oil is getting to the cams ...

because my engine has done 230 000 ks do i need to use a thicker oil because thinner oil now burns quickly. i use the 15w40, maybe i should use a 20w50 or 60???
