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 |
Re: Switching Head bolts
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. Mike 86/00 CJ7 Laredo, 33x9.5 BFG Muds, 'glass nose to tail in '00 88 Cherokee 235 BFG AT's William Oliveri wrote: > > Just had my engine rebuilt.

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.

Re: Switching Head bolts
He already has a mis match on the head gasket Steve.
He is putting a 4.0 head onto a 4.2 block. That makes it a 'twitchy' installation to start. 'I' would not take a chance on blowing a new engine for something that dumb. Maybe that is just me, but.... If I forked out in the order of $2K plus I most certainly would not take a chance on a head gasket that 'might or might not' be compromised. I have assembled and have seen assembled a whole pile of engines over the years and most people, let alone 'mechanics' stop and think when they find 2 head bolts that are nutted studs instead of bolts. It seem 'logical' that these 'strange' bolt like things should go somewhere special eh? One is for the bracket, the other goes on the back drivers side corner for the ground strap to bolt onto. In all due fairness poor Bill's 'mechanic' is kinda on the brain dead side to just put it together wrong without checking wouldn't you say?

Re: Switching Head bolts
Hi Mike,
Cut him some slack, I can see where an engine builder may be confused as to where a head bolt with the stud would go, I don't know of any book that would tell him where fifty years of different brackets would attach. Anyway, the installer should be able to swap bolts.

Re: Switching Head bolts
Mike, the mechanic didn't put the thing together. The rebuilder/machine
shop did. They did the rebuild on the short block and put my previously machined 4.0L head on it. There are two entities in this process. 1. the R&R guy, you can call him a mechanic. 2. The Machine Shop/Rebuilder. #2 is the one who bolted the thing together and I choose him because he has done this mod before and is fully familiar with it. This guy has a history of jeeps including racing sand jeeps. He's the best I could find in this area for this application. And He warranties the work for a year. He confirmed that it would be no problem for #1 (mechanic) to change the bolts so if he's wrong he'll have to fix it if it comes down to it.

Ha ha.... I'm getting to know you well Mike. After the last post that I
knew you'd have that reply as I was thinking I'd have the same reply. :-) Thanks for the Devil's Advocate. I certainly hope my 'luck' doesn't fall into the 'bad' category from here out. I'm already shot to my bones with nerves on this one.

Re: Switching Head bolts
I just have to add my 2 cents here Bill. I hope to heck that whatever they
do to fix the bolt problem works out for you. Things like this make me glad that I rebuild my own stuff. Anyway, for what you paid for the rebuild, I would insist that they change the head gasket. I don't know what type of gasket they used, but some of them form quite a bond to the head and block surfaces, so relaxing the bolt torque could cause the gasket layers to separate slightly. Then it becomes leak time. Like Mike said, since there were different types of bolts for the heads, the guy should have at least asked you where the special bracket bolt belonged, unless he knew for sure (which he didn't). The second thing here that would raise a red flag is the fact that the rebuilder didn't insist on changing the gasket after his oops. I rebuild engines in my own shop and would never risk that. Is he going to do all the labor and reimburse you for your car rental, towing, etc. if the gasket fails? If not, I would insist he change the gasket. The gasket is probably about $40 at most, and and hour or two of his time to do it right. IMHO, this sounds like poor quality work.
