Ok, it's mega stuck, rounded off and I want to cry.

Can anyone help me with some extra ideas on how to get this bolt out.

It's the number 4 bolt holding the injector in the block on my 1.8 TD transit connect.

I have replaced all 3 of the injectors but this one is faulty and it's the only one I really needed to change!! ha ha.

Ok, I tried

Day 1

almost a full can of WD40, 6 + hours of soak.
Heat to the point of cherry red and pipe freeze in cycles.

the 10mm head rounded :-(

Day 2

I bought the Irwin remover kit............total bobbins, won't grab it enough to turn with any force and further chewed the bolt head.

It's just under 10mm spanner width now, but I can't wedge a screw driver head in to compensate due to not being able to swing the spanner in any way to losen the bolt due to space.

It won't take a 9mm socket, 10mm socket slips, I can't get grips into it as it's slightly sunken and I couldn't get any force on it anyway if I could.

Properly peaved off!!!!

HELP!! ha ha.

 

dill the bolt head off, remove the injector, plug the hole to stop any crap going down there and then a set of long nose mole grips should wind the thread out. im guessing its stuck because of the torque on it, rather than siezed in the head.
ive never looked at transit connect injectors so this might not be possible but ive removed plenty of bolts this way.

 

need a piccy......

Drill a pilot hole and use a big ease out.

weld a nut on the top??

can't say without seeing it

 

I feel for you. 3/8???

 

as said weld a bigger nut on top. remove it while it's still hot.

 

try and hammer a 9mm socket on there or weld a bar or there

 

Cheers lads, really appreciate the advice.

I tried the 3/8th slipped again :-(

I think I'll dremel off the head of the bolt as advised. I can see this being the best option. It's defo over torqued not siezed in there.

I'll hit the threaded shaft with the heat and wd40 and I will have space to fit in some grips too.

I'll post a piccy so as to show how the injector is held in, and how badly the access is to a silly 10mm bolt, and also the mess it's in ha ha
