Bad Tuner

[bnr#@]

you mean we should take out the studs and get the surface flatterned?

That would be the only way to do it properly, given the heat any kind of putty/cement/anything you put in there will just break up/melt

[Adriano]

Its more likely the manifold than the head itself, is it a china stainless manifold, they are soo far from flat at both flanges it isnt funny.

[R31Nismoid]

Ah look @ that, it started off as a bad tuner

And now its turned around the poor fitment of parts by the owner

funny that.

[femno]

Haha nice one.

Still, knocking can be avoided in any case...

This situation is so typical, backyard mechanics install their awesome stuff and take the car to the tuner where they find everything is wrong, then blame the tuner.

Save yourselves the hassles, take it to someone who knows what they are doing.

P.S the only way you can machine the face the manifold seals on is to remove the head! You shouldnt need to do that unless youve dug holes with a die grinder or similar cleaning the old gasket off or something stupid like that. But still wouldnt surprise me..

well, i mean it still can be a bad tuner cant it? why would any tuner tune a car that isnt up to scratch for tuning, and then also, why would he blame the cams? it doesnt make sense, you would think a tuner that was switch on would say, nar couldnt tune it because of this exhaust leak blah blah blah,

also the fact that a disco potato made 310hp (230kw) on 11psi is sus, i dont think its even possible,

so then again, its not down to poor fitment of parts,

I'm no tuner but... Looking at the boost curve I can say its not the tuner thats the problem.

Take the manifold to any engineering shop and get them to face the manifold if its leaking as much as you say its probly out by 1 - 2mm from being welded and not bolted down uring the process.

[gfunkk]

they are a bad tuner, what kind of tuner still tunes a car despite it having an exhaust leak?

they didnt even call the customer first to check if he still wanted the tune despite the leak...

here is the problem (see pic)

[MrStabby]

What brand is the manifold? Cracking on the weld is common for non-name stuff. It looks very thin... So are you going to replace it or try to get it welded up and hope it hangs together? The mounting face looks thick so it probably true, but check it anyway.

Re: the tuner going ahead and tuning something like that, yeah i have to agree with you guys now. He should have aborted the tune and called. Take it somewhere else next time.

[murrayis]

Dam thats a bad crack! even the support is cracked..

Yes the tuner should of aborted as soon as it wouldnt build boost etc. how long did he try tune it for?

[sly32]

putting stock manifold on i believe? it looked like a proper mani but guess not hey, the tuner still charged him the 600, so im guessing it was on there for the full time, you could hear the leak very easy when bonnet was open, also from what i was told (which gfunk can comfirm) he said i could only tune it for 11psi, and not 16psi because of it pinging, you have a exhaust leak aswell,

so yeah this does mean a bad tuner, specially when he blames the cams for the problems?

dodgey backyard mechanics, can hardly blame that for problems, no dogey stuff goes on here

so, when the car gets the manifold put on, and enough money saved for another tune, i think hes taking it to matt at pits to tune.,

i guess then we will find out what the program is like

(Gfunk is the one that spoke to the tuner on the phone, my other mate is the 1 that owns the car, reason gfunk spoke to the tuner was because our other mate doesnt know to much about cars,)

i told the guy to get a new manifold but he took this one and got the crack welded, so we will see how it goes.

no more leaks though
