Help with new mani fitted

[supernova]

Hey everyone, just fitted my SPS stainless mani (great bit of kit!). But after fitting, there a strange noise whenever throttle is applied. Just wondering does it sound like a leakin gasket or something else or is it normal? Sounds like a farting noise! hahah Haev a look at the video i took:

sounds a bit wrong tbh

check see the the top of your decat is tight against the turbo - is there a leak there by any chance?

its got a leak... did you use new gaskets? preferably toyota. if yes, then take it to a machine shop to get the two surfaces skimmed, and install it again.

whats the best way to check for a leak?

 

[Aidan@EP-styling]

when its NOT hot you could start the engine and put your hand around it and feel for a blow out

Bit of paper mate.

 

[Dub-Se7en]

check for sooty deposits around the mating surfaces, that'll give some clue to where it's blowing too.

Haha it get hot very fast!

Was thinking just blowing some smoke around haha

but i think the paper idea is good

Washing up liquid and water. Bubbles init. Roffles.

How does it perform? When i first fitted mine it sounded like this and i could feel where it was blowing from, i took the car for a spin and no power whatsoever! Then i re-installed it and it still sounds like its blowing, but defo performs better. I think i need some new gaskets for it though tbh and could do with it skimming

same mani rik?

 

[Chris@CCM]

did u use new gaskets ? do u check the faces to see if they were flat ?

 

[supernova]

Tbh i didn't use new gaskets cause they looked ok to me. Also because before i fitted this one, i fitted another oem mani that i ported and that was ok with the used gaskets...

 

[GTnomez]

ive got the same noise and i didnt take it off but i cudnt find any sooty deposits anywhere on the mani and i had brand new gaskets, so i dont no what it is

soundsl like the leak is between the head & the head flange.. well if it was from the mani itself the sound would be different..

but as alex said.. remove, check if flat & then if not skim & refit

I always advise new gaskets buddy. New manifold new gaskets i would say your old gaskets are far beyond the use by date and may need replacing.

Yeah really sounds like a blow. I would replace the gaskets and do the nuts up tight and see where you go from there .

 

[supernova]

I just hope gaskets will do the job, don't like the sound of the mani needing skimming...

Hi,

I would also advise stripping it apart again and putting in new gaskets. I doubt your manifold requires skimming but Id say have some sanding paper to hand to even out the flange on the head and flanges on your downpipe (if its a used one), but be careful to not over sand any part. When tightening up again tighten each nut equally and hopefully it should be fine.
