Don't sell it. You'll love it when it runs. I had the same thing going on with my wiring when i did my swap. Once you fix it you'll be happy. Check the clutch when its running man. He had a good point no one considered.

SLiDe_WaYz · 05-08-2011, 04:25 PM

Just started it, pressed in the clutch and shifted samething.

Checked ALL gauges and everything is normal:
Wideband: 13.8 at idle
Oil Pressure is at about 90PSI which is normal when first starting since the oil is so thick.
Water temp is normal
Vacuum is reading at 14 instead of the 20 before hand.

Now, I backed it out the garage and killed it, and it SOUNDED, im still not 100%. But it sounded like it was coming from the intake manifold side. Im wondering if it is a vacuum leak would it honestly cause that big and loud of a noise ? Not a pity story here, but I'm in serious need of transportation lol I'm sick of getting my girl to take me places.

McSlides · 05-08-2011, 04:27 PM

It definitely could be. Pull the manifold off and put a gasket in it.

SLiDe_WaYz · 05-08-2011, 04:36 PM

I ordered the gasket upper plenum and the intake manifold gasket from NissanCC last night. I'd still like to know if a vacuum leak would cause that loud of a whistle lol. Im just curious that noise is ridiculously loud. When the engine was pulled to install the pilot bearing, we did chain it around the intake manifold. I just would like a definite answer as to if anyone has ever heard a vacuum leak make that noise ! lol

camaro379ss · 05-08-2011, 06:07 PM

It sounds like it could be a large vacuum leak. I have heard large leaks before and its usually a high pitched whistle and causes really high idle...hard to tell on an internet video, but one problem is when you shut the engine off it doesnt get quieter as if its running out of air. It just stops abruptly. Thats one thing that makes me think it may not be.

You can rule out the intake mani by getting a spray bottle of soaping water and spray around the meeting point to see if the pitch changes. Either way it still needs a gasket but thats not anything new to you I am sure seeing that you ordered one.

Are you sure you didnt damage anything around where you chained it?

SLiDe_WaYz · 05-08-2011, 06:32 PM

The chains were as followed, two bolts that went into the links and then went into the holes in the block, that was the exhaust side. Now on the intake side I removed the fuel rail, and ran a chain through one side of the intake manifold, and looped around 2 of the runners. Then hooked them to the house and lifted it out.

I'm pretty damn sure I didn't do anything to harm the engine when pulled out.

camaro379ss · 05-08-2011, 06:34 PM

try spraying some soapy water around that area to see if it is a vacuum leak. Just control your spray.

SLiDe_WaYz · 05-08-2011, 11:41 PM

Got some bubble action on the intake manifold. So I know there's a leak there. Again not sure if it's causing the damn noise though.

hessianben · 05-09-2011, 12:48 AM

well either way, you gotta fix that leak or you'll be having other running issues... hope that's all it is!

SLiDe_WaYz · 05-10-2011, 02:47 AM

Memberofthe600hpkaclub · 05-10-2011, 03:14 AM

camaro379ss · 05-10-2011, 09:14 AM

thats some bad luck for ya...but I agree it really does sound like the intake gasket is it.

SLiDe_WaYz · 05-10-2011, 11:38 AM

Never I wouldn't never put anything eBay on my car lol. My buddy sent me a text last night and said he ha a peakboost gasket in his garage he'll give me if he can find it. If he does I'm going to cancel my order and grab his.

jr_ss · 05-10-2011, 01:46 PM

You need to look else where. There are plenty of shops that have these gaskets in stock.

SLiDe_WaYz · 05-10-2011, 03:48 PM

Not where I live, no shops here carry anytype of jdm part. At all.

jr_ss · 05-10-2011, 04:05 PM
