Just Replaced Head Gasket - Now Weird Whining Noise, See Video

[Manuel Kasko]

Yeah maybe take it to a tuner and let them check the air to fuel ratios just to make sure.

My stock computer was running 13 psi and never blew a head gasket. Stock tune with stock or close to stock boost shouldn't cause an issue at all.

Wear and tear could be a factor maybe the the person before you gave the car a thrashing

[Booki]

Could have had a hard life like alot of skylines, but strangely enough my bottom end looked really good, and the fact that the head had never been taken off the car or touched before was also a good sign

Was thinking of picking up some shell helix hx7 to rum through the car before filling with motul, should be fine running cheaper stuff for that purpose yeah?

Its $20~ odd at super cheap wonder if anybody actually runs that oil ...

[Manuel Kasko]

I have done it before just to give it a good clean out. Run some shit oil for 100km or so and just don't thrash it at all. Dump that and top up with quality stuff

Right now I have been running penrite 10/30 or 15/30 for about $50 per 5L and the car likes it.

I just change it about every 3-4 thousand ks

like they all say the timing belt is to tight mate, or the idler bearing or tensioner bearing is bad.

Going in for a tune tomorrow, I've got -7s on it.

Still hearing some hissing, horrible noise is gone so was the timing belt. Oil is staying clean.

Just gotta find this vacuum leak. Any pointers or common leak areas?
