Is there a tool for this?

[ROTFL-ACT]

Well my oppinion would be to sweat it out and do it right 1st time.
I've been burnt too many times in the past also trying to find easier/quicker fixes for similar type problems as this esp when it comes to space etc..

Hope you manage to fix it soon

Yep, you're right.

I'm just going to have to pull everything off and do it right. I've got the part numbers to I will just get a new pipe and gasket from Toyota rather than stuffing around with bolts and drilling out threads etc..

Thanks again to everyone for your help & suggestions

Thanks for the advice guys.

After a dodgy attempted repair I decided to do it properly - removing the turbo etc.. to get at it and replacing all the affected parts.

Got a new coolant pipe and flange gasket from Toyota as well as the connecting hose (which appears to be where the leak was). Parts had to come out from Japan, and they were unable to supply the 6mm studs AND I couldn't find replacement studs anywhere!

Here is the solution I came up with:


6mm high tensile bolts and nuts!

Bad news is that it is not "standard". Good news is that it is at least twice as strong and there is no risk of pulling the threads by overtightening the nuts
