Injector hold down bolts

[mike diesel]

I lifted one with OEM bolts.. I put 8.8 bolts with washers back in. No problems
I replace rocker shaft bolts with ARP bolts not studs.. They are cheaper than OEM as well

I do already have arp rocker arm studs. I saw the arp bolts but like the studs better.

With a lower compression motor, there is less cylinder pressure right? So technically a lower comp. motor would be better on stock hold downs?

When installing the bolts, do you put any lube on the bolts? Or torque em dry?

X2! I alway's use ARP lube in the threads and under the head of the bolt.

There's some interesting opinions both ways in here:

I'm just giving out the info that I have personally used many times on the original OEM bolts and have not lifted an injector, yet. Been reused a dozen times and I am not a retard that puts so much lube on the bolts that it hydraulic locks the bolt from seating all the way. I'm sorry but that takes a real crappy mechanic to be that dumb about how bolts work.

I used ARP lube on mine and it fixed my issue .

 

[mike diesel]

I've got a big bottle of ARP ultra torque lube. I'll lube mine for sure. I like a good lube job.

Ran the stock hold downs on the new motor even with the compounds and all has been well. But I've got some big fuel going in right now so I said screw It and picked up a set of PDM billet hold downs and arp bolts from industrial injection. Good feeling not having to worry about it anymore.

How big are you going? I'm hoping to hear you are shooting for 10s at RMR.:woott:

 

[mike diesel]

I picked up some 120% nozzles. I'll be going for 10's next week.

Awesome. Good luck. Want to sell the 30 overs?

Are those washers beveled like the head of a stock hold down bolt? Would they work with a stock hold down even?

 

[mike diesel]

Yes they are beveled. I asked if they sold only the bolts and he said they only sell it as a complete kit.

So I wonder what happens if you "break or lose" them?

Cry.

Are people actually bending the stock hold downs or just bending/breaking the bolts?
