Why would my injectors be loose in this new cylinder head when I have the hold down nuts torqued to 44ft-lbs??? I can pull up and down on the injectors in the head. I was like ***???!!!! I rechecked the torque and its right on. Funny thing is, when I hand threaded the hold down nut in the new head, the nut pretty much bottomed out with not much resistance. I was thinking, how the hell am I gonna torque it if I have no more threads...

Also broke a exhaust manifold to head bolt, I don't think the hole was tapped very deep. I am not too impressed with this ****en new head LOL. Ok. Bill.

 

Bill, not sure if the injector nut uses a tapered thread, but it sounds like they may have tapped to far down? I would be calling the vendor on this one.

 

Ah, they'll ride up with wear.

That is some wierd stuff, Bill. I hope whoever you bought it from treats you right.

 

Ya that sounds like it really sucks. Nothing like running into barriers when your trying to get things back together, good luck!

 

Bill, I think you pretty much nailed it, the threads aren't tapped deep enough or the injector bores are bored too deep. I'd put my money on not tapped deep enough.

I hope they treat you right, if not have no mercy on them.

 

Yeah, I'm not too happy with them right now. I'm gonna try a thicker injector washer first, before calling them. I'm trying to use the .020 washers. R&D!
