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

      RB26 block, rb26 head

      Block bump. $400. As above cyl 6 needs bore or sleeve.

      I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.

      Ethanol Content Sensor - Always at 11%?

      By Kinkstaah · Posted

      I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.

      From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.

      They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
