Not only is the manifold/downpipe leaking making it sound like a tractor now there's a squealing noise on full boost at 20psi but no noise at 16-17psi. Any ideas. I've added a video in second gear full throttle at 20psi.

Problem after problem.....

Was just thinking, could it be the exhaust leak making that noise once it at full pressure?

Sorry dude, got your whatsapp yesterday, was in the office all day!

 

Can't really hear it in the video, but if you have a scream or wheeze on boost, then check all your couplers and condition of your hoses as it sounds like you have a boost leak somewhere.

Oi only takes 10seconds to reply.

I did a boost leak check the other day and I had a few small ones which I've since fixed. Unless it's only leaking once at full pressure then maybe. I did tighten everything else up aswell. Can't really pressurize the system enough to leak test it. Don't wanna blow a seal.

I didn't have much time yesterday - you have no idea! :lol:

 

You won't blow a seal doing a boost leak check dude. That's what I'd do.

....I'm staying up near Heathrow next week (Monday night), if you're about.

I have migrated to south London....

I'm sure I will be taking a trip to powerzed soon to sort this exhAust leak so we could have a little meet then if anyone else is about.

How is jimmer? Busy? I wanna get booked in.

I couldn't hear much either. If you keep hitting 20psi in second gear outside a school though your gonna get pinched.

Oh sh1t your right, not very responsible at all. Delete delete.....I can hear the noise in this vid. It's a kinda high pitched pulse noise. Can't believe you can't hear it it's really obvious to me. Listen again. It's not a whistle or whine but like a child screaming.

Really hard to tell mate, as the clip is so short, i played it over about 20 times and can possibly here some sort of exhaust leak possibly. Rolling road or on a ramp with the wheels lifted might be easier to diagnose.

Bloody el, hi mate.

It's been a while hasn't it. How's the 300?

 

Anyway yeah there is an exhaust leak aswell but thats a whole other problem. Im hoping it's only the downpipe which the noise does seem to be coming from, fingers crossed.

 

Will check for more boost leaks 2mow.

Its been off the road for a year now lol, going to be doing a TT conversion with a spare zed i have, ive noticed youve been down the gym alot since i last saw you lol, didnt recognize you at first :thumbup1:

Yeah like anything I get involved in I get a little obsessed, but in a good way. Eating healthy and staying active etc.

TT Conversion sounds good. Will open a up a whole new window for..... Problems hah and good fun too.

Get that exhaust leak fixed mate. Regardless if it's THE fault, it's A fault that needs to be rectified. If it fixes this all the better, it certainly isn't making things better.

Yah and it's ruining the driving experience, driving me mad, embarrassing . Just trying to find someone to do the work at the mo.

Drivers side exhaust manifold yeah?

Correct, but now that I've listened to it so much and it's gotten worse it's actually coming from nearer the back of the engine where the downpipe is. I'm betting it's my z1 downpipe that's cracked would explain it getting worse especially after I've just had the rest of the exhaust fabricated it could have added extra tension/weight and spread the crack. Problem is I can't see the crack coz it rapped in fibre glass. Fingers crossed. Will have a go at removing it myself soon. Remember it being such a pita last time I removed the drivers side DP.

Removing an aftermarket down pipe is easy, it's rusted solid stock ones that cause problems. Starter motor off, 3/8" ratchet and a UJ and a ring spanner for the bottom ones it will be off quicker than it took to get the car off the floor.

I hope so mate. I remember having to make a tool to get one of the top ones off, welded 3 old ratchets together at a certain angle lol was madness. Mine are five bolt design so hopefully should come off easy. Defo not rusted so much. I will jump for joy if it's only the downipe that's cracked. Will take it to my boys who made my exhaust they are awesome.

They ally welded my water injection bungs on last week.

 

I remember from my 200sx days that you would get a scream from the exhaust if the turbo go manifold gasket was gone. Maybe not but just a possibility
