Could be... could also be the car has had its km's wound back and is way over due for its 100,000km service which is why its reccomended to do all the belts as soon as you get the car.

If you spin a bearing its engine out, rebuild time.

99% certainty it hasn't done 99,000km.. even though it still does look "clean" and spotless.. so does an aussie car that has done 150,000km

Take it to a proper garage, that *knows rb26dett's* and get it inspected fully.. everybody can armchair guess for days on something like this and its not going to get you anywhere.

With this "spin a bearing" what happens ? do i drive along and the engine blows up or what ? can you get it fixed now ?

If your conrod bearings are worn or they pick up a little, the knock will get louder long before one ( usualy number 6) or more spin .

The engine will be fairly quiet when you first start it up ( cold thick oil ) then as it gets warmer it will knock more , if you spin a bearing it will sound more like a diesel (very loud ) and could say goodbay to your crank then . If you keep driving it with a spun bearing then you could break a rod and make a big mess .

I wouldn't bother driving 5hrs if thats the case.

Take it to any one you can trust that has experience with the good old VL or R31. The bottom ends are basically the identical when it comes to bits that go round and round, up and down.

another option is to drop the oil out and send it off for analysis, they will be able to tell you if there is a heap of bearing material in it....if not it is very unlikely to be a bearing....but if so.....

That's what I thought too, until a friend had his oil analysed after a slight knock developed. It came back all clear...no signs of metal.

50kms later the knock got far worse. The engine is out, but he hasn't stripped it yet, but it seems like the number 6 big end picked up.

you will need a bottom end rebuild

but if u drive around with a spun bearing for a long time..

your could actually damage your whole bottom and

ie block crank conrods etc

      I was very unimpressed with how the car came up from the A pillar forward, before I hit things (twice). It all has to go. It had to go, but now it has to go... more. So we finally found the very first Shennanigans with the entirely perfectly setup engine that had no problems being pulled apart to improve on 'was perfectly fine'. Cam bearings looked a bit... stock. Which isn't entirely bad given they were stock and this is a ~20 year old engine. So new cam bearings are on the way because it's somewhat difficult to get to this stage to do it later, and it will trash the block. It was quite unusual that it wasn't done when the perfectly new-looking VCM cam was originally installed by [unknown] What IS unusual is the cam that was installed there was advanced SIX degrees. As to why there is no way to know.. however it could have been @Dose Pipe Sutututu's mate who wanted a larger cam sound but also wanted it to come on earlier to be more usable. This is my dyno sheet with the previous setup - This cam is not supposed to peak until 7000+ RPM, according to VCM. This is what lead me down the whole 'my heads/intake setup is running out of puff and can't support the cam' line of thinking to begin with. Anyway too late now - New cam is in! It could be rather funny if this smaller cam acts like a larger cam because it isn't advanced six degrees. In the spirit of everything is working amazingly - the COMP cam required no dialling in whatsoever. It was about 0.5 degrees advanced, which seems pretty bang on. Any adjustment either way would be further out. I'm told as a chain breaks in it ends up regarding back about 0.5 a degree as the chain breaks in, making it bang on. In the spirit of everything was previously working amazingly - The timing gear that was taken out turned out to be was an N-Motion double timing chain kit, with adjustable cam gear (which is how it was 6 degrees advanced) and all looks entirely perfectly new. It also had a Torrington bearing, which was one of the reasons I ended up getting the Cloyes kit which they used in the C5R 24 hour racecar - Because I couldn't confirm what was in the engine when talking to Tony Mamo. I did believe however it was a Double chain kit of some kind... but found no supporting documentation or evidence for it.

      I recently did this to my R33 with the full set from Car Mats Direct, they can't do the vinyl anymore that's advertised on the website due to a supplier issue so I ended up with the Black Loop Pile which looks great. I went all out with rubber sound deadening sheets from Repco and also added the sound deadening foam layer option with the carpet. Makes a world of difference and got rid of all the weird smells in the 29 year old interior. It was a bit of work but I'd 100% recommend it, Car Mats Direct had awesome customer service and quick postage. Replaced my seats with some sporty ones from Autotechnia while I was at it, feels like a new car.

      Got the motor out and torn down. I'll be dropping off the block Monday. Luckily the scoring on Cyl6 is much less pronounced then the pictures made it out to seem. It can barely be felt. If you pass your finger over it 10x you'll barely notice it. Hopefully by some chance it will only require a honing. I'm not in the mood to buy one size larger pistons or another block. Oddly enough my 6th cylinder with the scoring has extremely clean intake valves compared to my other 5 cylinders. I'm worried the scoring was caused by too much fuel or Water/Methanol washing the cylinder. I'll review some old logs to confirm.  This was also the first time I pull an engine with the transmission still attached. It went much better then expected. I was worried my CD009 wouldn't make it easy due to its sheer size but it was much easier this way.
