(rev 2 turbo).I originally helicoiled it and that seemed to last till a track day which must have been too much and it started blowing in that area.
Ive removed the turbo and decat already so there is a bit of access to the bottom rhs stud.
Ive tried rehelicoiling it but everytime i put some torque onto the stud it just pulls the helicoil out and doesnt tighten.
So it seems i may need to get this done properly and time insert it.
Ive asked for local mobile mechanics for a quote if they can do it with the head in situ.However, i dont have much confidence this can be done so i may have to opt to remove the cylinder head and send it to a engineering place to get it done properly.
So a few questions:
1.
Is there any alternative to helicoiling apart from time insert?2.
If i have to remove the cylinder head then ive read i can do this with the inlet manifold still on it which sounds easier. Does anyone have an idiots guide to this?Im quite confident i can get the head off except what to do with the cambelt? Can i just cut it off? Im not at all confident in fitting and timing a cambelt kit so was going to remove the cylinder head, get it sorted and then reinstall myself with new rev 3 head gasket and head bolts and then get the car towed to a specialist and get them to fit a new cambelt kit.
I would then reinstall the turbo etc myself to keep costs down so the specialist will only be doing the belt and idlers.So more questions:
3.
Do i need to put the engine into any "state" before cutting the belt to remove the head?4.
Can i just put the head back on without it being in the same "state"5.
what parts do i need to do all the above?6.
Anything else i should do while the head is off?(such as rev3 inlet cam?) Any upgrades (keeping costs down so rev3 management/rev3 head is out of the question)Sorry for all the questions but want to prepare myself!
