What actually happened when you spun your bearing? High RPM range? Oil starvation? I'm scared to death one day my oil pressure will just drop off and spin a bearing haha. Over reacting I know but still.

How long untill you think your going to be out and about on the road? Standard rebuild? Feel free to PM me if you don't want this on the public forum :D.

And luke for the short term I hope its not rebuild time but a stroker will be awesome in the long term.

It's all heslo's fault!!! never give him a ride in your car!!! =P

well, the part on the side of the block that you screw your oil filter to has these 2 metal balls at the end with springs on them to create oil pressure, the one that returns oil to the sump twisted and blocked off oil return. Combined with a fairly cold car (thick oil) managed to starve it and run the bearing for cylinder 6, but it had a bit of help - i also missed 3rd gear (gearbox was getting a bit fussy) but was also chatting away to people in the car not really paying attention 100% to the gear shift, if felt like it went in, but clearly didn't so it smashed into limiter on that change. =\

im hoping it's only going to be a week or 2 before i get my car back for run in (should be about 10 months off the road)... i considered stroker and rb30 bottom end but just did have the cash for them, so i went for a stock rebuild.

and it was cold??

man, I always baby my RB until the engine is warm; that means NO boost whatsoever and always under 3000rpm

smashn thru the gears and bouncing the rev limiter on a cold engine is plain silly

sorry, you make baby jebus's RB engine cry

:D

cold car

limiter

:P what am I missing?

anyways, dont mind me mate, i bark on heady days but dont bite :D

no probs... car was moving and in 2nd, went to change to 3rd but it didn't go into gear, i thought it was in gear and went to accelerate as normal... problem!! try it yourself if your game, drive in 2nd till your just starting to make boost (engine is under positive pressure), throw it into neutral and accelerate like your changing into 3rd and continuing to increase your speed - u might be shocked at how quick the car will fly threw the revs! and when u've got passangers your chatting to, that spit second of 'hey, whats happening here?' is disasterous!!

I do the same, I wait till oil temp is at least 70c before my intake manifold sees any positive pressure from the turbos

Guy across the road had a 4WD. Held it on redline one day (who knows why) for about 10 minutes in the driveway and then BOOOOOOM it literally sounded like a gun shot. Heaps of smoke pouring out and stuff... was crazy! Must had done some serious engine damage. Didn't see that 4WD after that ever again. But they used to love revving their cars. They warmed up their cars by revving it to redline each morning. They had a small Charade that used to fill the street with blue smoke when they took off. They also owned a 240z... well, it was 2 240z's welded together at the chassis. Then he had a crash. Then the insurance company found out. Then the cops found out. Wasn't good.

Didn't Writeoff spin a bearing after attempting a 7000rpm launch? Or was that someone else? I remember reading it on here.

I don't dare to take the car over 2800rpm while oil temp is under 70.

Fishpaste, did you notice a decrease in oil pressure when this happend? Or did you just hear the sound of the spun bearing clapping away? Usually when you spin a bearing, you basically lose all oil pressue...

my car wasen't that badly damaged from it, infact there were 2 sets of trafic lights inbetween where i think it happened and when we discovered something was wrong. there was no drop in oil pressure, tho thinking back, it felt like there was slight a drop in power. basically everything seemed fine, and it was when i was building up the revs to take off at the 2nd set of lights that we heard the knocking! i still limped the car around for a month and a bit after it had happened (had other work being done to the car) but when the damage was finally inspected the bearing had only slightly lifted, no visible marks on the crank tho it had hairline fractures and was 0.6 thou out of alignment from memory.

who knows if it would have happened with warm oil or not, also the oil was almost 5,000km old (i had just purchased 8l of motul 300v for a change - that i still have in my shed XD). But the core of the problem was that oil flow was serverly restricted and the car hit limiter. Perhaps i could have payed better atention and not bashed limiter but the fact remains that the oil flow was blocked and it would have happened sooner or later!

also, since my car i know of 1 other car that has lifted a bearing because the same genuine nissan part failed and blocked their oil flow (and it was a 34)! im not saying it's a common problem and hopefully no one else here will suffer from it ever, but it's another oil problem and not one most people know of!

well my car is back together after some reconstructive surgery and she seems to be doing ok. no noises, no smoke.

haven't done a compression test yet, ran out of time to take it to a workshop, but will do first thing tomorrow.

the little rb lives another day! (hopefully)

He did spin a bearing - not sure about the 7000 rpm part, but he did it during the middle of an SAU cruise - engine was well and truly warmed up by then.

i daresay its more to do with the engines getting 20 yrs old +

I've spent over $20k just fixing bits and pieces, making the car look and feel as new rather than going for the performance mods - I will be, no doubt about that, but I respect the fact that many people who have invested a lot of money into their engines have still blown them - which is why I've ordered N1's to replace my stock ceramics. The thought of those 20 yr old turbos is insurance enough for me to not over-rev or hammer it too hard - cant wait till I get my tax return, put it that way

Once I get those turbos replaced, some forged pistons, and a sump/head oil baffle and head return, wahey >:D

here comes e-vil doh-mar

Well, good news, I'm back in for the day! Car checked out fine and got 4 more PSI wound into her. Should be fun fun fun on the day! You organised a meet point yet Adrian? Perhaps a Vilis breakfast beforehand?

havent worked out a meet spot.. the only thing about villis is ppl coming from the north will go to villis then back to mallala.. but if ppl want im keen for it..

Don't care, did it for the John Bowe day I did not too long back, more than happy to do it again

even his lady friend wants him to do it properly. i foresee the stroker happening before the end of the year.

The Cougar Wants a Stroker

The ladyfriend wants him to do it properly

Before the end of the year

The Cougar shall be stroked
