Hey guys

got a rattling\rocking noise coming from my engine on idle...only seems to happen after it has been driven for a while...

thought it was the clear cam cover as when i put pressure on them the noise got quiter but all the bolts seem tight.

apart from that it all seems good. Any ideas as to possible causes? its a 34 gtr motor in a 32 gtr.

cheers

Aidan.

Hey Aidan, have you tried marking the CAS position and putting the OEM cam cover back on? When I originally put the clear cam cover on the teeth on the CAS were grinding because the clear cam cover is thinner than OEM, so I had to put some extra spacers on.

thanks for the reply dude.

yeah noticed that the lower bolts had rubber spacers that were not touching the cover so i threw some more on, made it slightly quiter but its still there...

didnt actually swap the covers over so ill give it a go when i get back home. Hopefully i can sort it before dome day.

bit scared about timing...kina like the wu tang clan, aint nothin to f**k with....

use a small screwdriver or blade to scratch the position of the bolt heads onto the cas before removal then do them up in the same spot. if ever in doubt set it slightly further clockwise until you can get a timing light on it.

    • I thought it could be an issue because the standard plate was flexing when stressed. Maybe the original gear set will hold a bit better without flex? Last time on the dyno it made around 670nm at the hubs. Now it have bigger turbo and better intake but have not been on a dyno yet. The car is being used from family trips to drag race events. So the shifts can be a little violent. It is grinding if I shift to fast so was thinking I should overhaul it soon.
    • From the factory on RB26s there's a fitting on the intake manifold collector/"plenum" that provides pre-throttle boost signal. That's how they did it back in the day, I figure it's fine to replicate it.
    • I would be surprised if that wasn't the issue. It's probably telling you, that even if you remove the plastic liner, you may have some other clearance issues that may occur too in some scenarios. IE, tyre to guard. It looks like someone has already rolled the lip, but you may still have issues in the future IE, turning and hitting a bump etc. The fact it changes how bad it makes the noise when you are going backward vs forward is highly indicative that it's the tyre rubbing. They do make a terrible sound, even if you're only pushing a project car that has a liner hanging down on a tyre!   Has the car been lowered? If it has been, what is the measurement from the centre of the wheel hub to the lip of the guard straight up?

    • Mark's a bit smarter than people give him credit... He'd convince the person that is to become dead, to drive him to the forest first. That way his car has no evidence in it, and he's free to dispose of their vehicle permanently how he sees fit too...
