i had my car at the workshop today and the mechanic realised that there was a problem with the clutch fan. when the car got to high revs the fan itself looked like it was made of rubber swaying all over the place looked like it was about to come off. has anyone had this problem before and whats the best thing to do about it and does a rb30 fit the rb25.

any suggestions would be great

cheers ben.

Personally I don't think it is a huge problem.

I had an R31 previously and was unfortunate enough to run up someones arse. The front end was pushed in a bit and I needed a new clutch fan (amongst body repairs). The front of the car was fixed etc. except there was one problem, when the engine was reved, the fan blades flexed so far forward they touched the radiator, forming a perfect circle on the radiator fins. Nissan had an engineer come from NSW to measure the engine distances, etc after the repairs and all was spot on. They tried 3 different genuine Nissan fans and they all did the same thing.

I think that the flexing is normal...simply something you don't realise unless it is brought to your attention. If the fan has no movement in the shaft, don't worry too much about it. I also believe that different fans will flex more/less than others depending on the batch during manufacture and the consistency of the plastic.

    • My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.
    • Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?
    • What about if you just give it direct 12v and earth?
    • Hi guys . Can someone help me  I bought an Android screen for my Nissan fuga but it won't turn on   
    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
