Rb26 Nasty Knocking

[GTR_JOEY]

ok your not against what i said, is still dont find it coincidental that he has more then likely spun a bearing after a 0-180km run

Im sure when nissan did their tests on the RB26 it wasnt on an engine with 355rwhp,

the stock sump works fine for a stock car but when the engine is making more then 100hp over factory specs then reliablity starts to decrease and things do go wrong

anyway... i know of a few people that run 6L in their GTR's...GTRSEAN has figured it out that 6L is low enough to prevent the crank whipping through the oil in the sump

So, if the oil is not in the sump, where is it?

How the could the head flood with oil? I would have though it was obvious that this would happen before the sump is empty.

You can still have some oil in the sump and not have it picked up...

For example, the engine is operating at high rpm like in this instance.. some of the oil in the head and is unable to drain back quick enough

The oil that is left in the sump is subject to G forces and is being pushed up against the rear of the sump..

It is entirely possible for the pickup to not be getting enough oil to supply the engine

so is it worth putting extra oil in a lightly modded gtr that sees a stab now and again??

I always run 6L for safety.

GTR Joey is right, and it only takes the pickup a second to miss oil and damage is done.

To the OP, can u please write that u were on a racetrack or private road because u were

commie u mean ? imo u cant hurt anythin by adding a max of 1 litre extra oil to an engine. if u are doin a track day or drifting u need to keep the pickup submerged at all times. xr6 t's hold 7l stock so ive never over filled mine.

Fairly sure he was just too lazy to type the word "negatives"

+1

Similar way that i spun a bearing. Whilst giving it a spirited run, the fitting that came off the block for the oil cooler and relocator failed.. Causing me to lose a substantial amount of oil..

Even though this is an extreme example of oil starvation, it still gives merit to the importance of oil control and supply.

OP, search for "oil control in rb's" .. Will give you good insight to the nature, and resolution, of the problem which you faced.

Your wallet being a little lighter

+ 1 for running 6 liters on a standard sump.
