I've been driving around with 2 broken exhaust manifold studs for a while, and pestering a mate about creating a stainless steel tubular manifold for a while....
Well, my mate has created the manifold, and this evening it is going into guinea pig testing on my engine! :tup: :tup: :tup:
So this morning I started the strip down....
After giving everything a chance to soak in (A LOT OF) plus gas for a while....
First remove the turbo heat shield, disconnect the turbo inlet hose behind the MAF, disconnect the turbo outlet hose, disconnect the vac hoses from the turbo and inlet hose, undo the turbo oil feed banjo & oil drain pipes, and unfasten the downpipe....
Undo the turbo to manifold nuts, I used a 13mm cranked spanner to get to the bottom one, the whole turbo assembly should then just lift out.
This is what you'll then see in the engine bay - at this point I removed the lifting bracket just to make access a little easier.
Thanks to the plus gas all of the stud nuts cracked off without issue, the only odd one was the one I've got an extenstion/wobble on in the above photo.... for some reason this nut was 12mm, but all the rest are 13. I suspect whoever attacked this last time couldn't get onto a 13 in there so fitted a 12mm nut - bizarre!
Manifold came off a treat - it has a very mild warp.
Now to tackle the two broken studs.... I bought a 4.5mm left handed drill bit hoping that it would wind out them out, after giving them a good wallop with a centre punch I got the bit on them but it just drilled in and they didn't unwind. So, out came the easy outs...
And they wound out first time.
Two new STOCK studs in, I've heard so much conflicting evidence about uprated studs that I figured I'd spend £3 instead of £40.
At this point I decided not to tempt fate and try remove the other studs.... I might change my mind when my mate shows up with the new manifold later :lol1: :lol1:
As you can see in the photos, I used a LOT of plus gas, soaked everything at every stage, and it really paid off.
