Squealing On Intake Side

[Chris_R33GTSt]

Hi Guys,

I have an issue occurring on my fairly stock S2 R33 GTST Skyline. At full boost with the solenoid on the high setting (above 4500RPM) there is a squealing noise that comes from the intake side of the engine along with a black deposit on the inside of the bonnet, above the intake manifold. I am running the stock intake with SMIC and a K&N panel filter.

I have not had too much of a chance to look at it as yet - has anyone seen something like this before?

Cheers,

Christian

If you could measure or at least give a more accurate description of where the mark is, it would be a great help

Like I said, I have not had too much of a chance to look at this yet. The mark is above the intake manifold towards the front of the engine, and looks like carbon deposits so it may not be mainfold leak. It sounds like it comes from the intake side of the engine - behind the instrument cluster.

It's definitely your oil filter leaking vacuum then

If its carbon then its not going to be your intake. Check for exhaust leaks. If there is carbon being deposited on the hood, then there should be some around the block or where the leak is at.

Sometimes sounds can be deceptive, it may sound like its comming from the intake side, but you are seeing carbon deposits which would make me think exhaust side. Mani or turbine.
