Thread: TD5 Head bolt oops

did you oil all of the bolt before inserting it? how about the underside of the head.

While it will work with the missing 45 degrees I'd say that it wont be helping the head/gasket very much and it will give up if you start working the engine hard.

Thanks,
I did not oil the threads as there was oil in the block's threads already.
Nor did I oil the under side of bolt heads.
Will try a different socket in the morning.

Sounds like it might have hydraulic locked to me.

It was tighter than the others right from the first turn by hand.
What's my options?

1) Try and tighten it more this morning and leave as is?
2) Remove it and replace with old bolt? A sinlge new bolt is very difficult to come by. Would have to get a whole new set.

I am a bit in between a rock and hard place.

I am not familair with the setup of a TD5 but generally I make sure that all sockets are clean and dry before trying to fit head bolts. On a V8 I go to the extent of picking sealant out with a dentist's probe, then blowing out with compressed air , then drying with cotton cloth on a screwdriver.

if you have a pool of oil in the bottom of the block hole , it can easily hydraulically lock.

I would try to get a single bolt and failing that reuse the old bolt in your position.

The bolt made quite a chattering sound on the 180deg turn.
Will try and get a bolt tomorrow.

Did you run a tap and a die over the threads before installing?

the bolts can be had seperately try MR automotive or fourwheeldrives down in melbourne.

providing you didnt finish the torqing procedure you should be ok to undo the bolts and go again HOWEVER...

if it was mine

I would be springing for a new set of bolts and going again potentially with a new head gasket.
