Evo X Question, Turbo to Manifold gasket installation

[spikem]

The gasket that sits between the turbo and the manifold is blowing quiet badly on my X, I plan to change the gasket tomorrow..

Q1 can i get awy with just undoing the X4 bolts that secure the turbo hot side to the MF or do I need to remove the MF to slide in the gasket?

Q2 This is making my car backfire really loudly every now and again why is that? and is it bad?

car drives and idles fine?? just sounds a bit 5hit and backfires alot. Paid €53 for the bloody gasket too

cheers

Evos E1-E9 you could get away with what you are suggesting coupled with dropping the down pipe off the turbo, and removing the oil return pipe from the sump side to gain enough clearence to let the turbo drop so you can remove and drop in the new gasket.

But not sure on the X as the turbo is on the rear of the engine lol.

Also you may or may not shear one of the 4 bolts so what ever you decide to do, make sure you have the engine running for a minute to warm them up before cracking them with a spanner.

Yeah I'll remember that cheers

I changed the turbo myself a few months ago, but I remember how much of a ball ache it was!! had to remove the DP, turbo elbow, turbo, air box etc... was a nightmare, dont want to go through even half of that again, especially as Im getting a new MF in a few weeks.. but I need to drive back to UK next week so It needs done, I'm just trying to find out the easiest way to do it?

If you changed the turbo recently Spike, you should remember that the back 2 bolts are actually studs, so your plan won't work! Unless you did what I did and replaced them with bolts for next time
If you didn't, you may get away with double nutting the studs out, I did and it took me an hour and a can of penetrating fluid

Yeah thats what I was thinking, I remember now. one of the nuts is rounding off. ffs

Well I finally found the time to change over the gasket today, only took me 2 an a bit hours.

I cant believe how badly destroyed the gasket is



where has all the bits that are missing gone???

And what has caused this to happen??

[spikem]

sorry, I still haven't worked out how to shrink the photos

[spikem]

see if this works??

nope.

[KenX]

Did you reuse the old gasket last time? Or maybe the turbo wasnt snug up against the manifold? I can't think of anything else that would blow the gasket.......

Yeah I used the old gasket for the new turbo (as they cost €53!!??) fitted a new one today.

Cars flying again now

But I'll need to do it all again in a few weeks when I fit a new MF

Them rear studs on the turbo are a pain in the backside!!

Drilled mine out and replaced with bolts to avoid the problem next time, MF swap now takes 45 mins

that sounds like a good idea to me

Might do the same.
