Rb25det Engine Noise

[AzN]

There's a knocking sound on my GTS25t and I don't know what it is. I hope it's not a rod bearing .

The noise happens when I'm around 1200rpm and stops when I go higher then 1600rpm.

I'm using Castrol Magnatec 10w-40 and BP Ultimate 98 octane.

Heres a link to a video I made showing the problems.

its hard to even determin via video

but still, that is a good effort i must admit.

the sound does sound very constant

try listening to all pulleys first.

to do that, get a long screwdriver or a long solid metal rod of some sort.

place it on the Bolt in the centre holding the pulleys onto... the pumps and crankshaft pulley...

put your ear against it and hear if there is any excess vibrations.

sometimes on older skylines, the bearings could be buggered.

try this first and let us know... then we move on the next possibilities....
