Switching Head bolts
 

Just had my engine rebuilt. New cam, new crank 10/10, new bearings, new
pistons and rings, flywheel balanced and all married up to my 4.0L head out
the door.

Now the R&R guy has noticed one of the head bolts is out of position for the
power steering bracket so he needs to switch them.

Is there any problem switching two head bolts which reside side by side
without going through the entire torquing sequence again?

That is, can these two bolts be taking out, switched, put back in and
torqued down without any problems?


R&R guy says no problem.

Thanks,

Bill

I don't know where some of these 'mechanics' come from....

He put the 'wrong' bolt in the hole.....

Man oh man, if it wasn't for bad you wouldn't have any luck at all would
you?
;-)

I for one most certainly would not accept a rebuilt engine with an
already 'blown' head gasket.

Head gaskets only compress once.

Re: Switching Head bolts
 

I've done it hundreds of times and there won't be a problem switching the
bolts and just re-torquing those two. In all probability it's one of the
outside bolts which are the last to be torqued in the sequence anyways.

In all fairness to the mechanic Mike, these guys have no way of knowing
which bolt is supposed to have the stud on it and different installations
sometimes have different positions for that bolt. May not be the case with
all 4.0, although I doubt that they all come the same way in all
applications. I know for a fact lots of Pontiac, Buick and Olds v-8's would
have the head bolts with the stud on it in different locations depending on
what model vehicle it was going in and the assembler would have no way of
knowing.

Re: Switching Head bolts
 

The 'mechanic' is a full time engine rebuilder. I just called him and he
said no problem to switch the two bolts. Just torque it down to the correct
value and you'll be set. He's the one warranting the job so I'm happy.


Thanks,

Bill
