Injector hold down bolts

[mike diesel]

Where can a guy find new oem injector hold down bolts? I'm hesitant to reuse mine on my new engine since I have already "reused" them probably 5 times.

Not looking to go with billet holds down at this time. I'd rather wait for a stocker to fail first.

Are there any other bolts people have used? Grade 12.9 allen head bolts maybe? I have access to a massive bolt bin of top grade/quality fasteners. Just curious if it's either oem or billet hold downs or if there is something else people have used with good luck...

Hope you don't push one and torch a head. Next time my injectors come out, billet hold downs will be going in. I know way tooany people that have pushed them out. I don't think the bolts are always the problem, the hold down itself bends too.

Wonder what "grade" the OEM bolts are...

I had a local dealer order some for me. They cost a little over 4 bucks a piece.

If you do use bolts you have access to make sure they are conical.

ARP makes studs for that. I know socal sells them with their hold downs.

I agree with Harbin. I just went through this with my built motor in October. I was lucky and it didn't torch the head.

Get the billet hold downs and be done with it. Heads are expensive and time consuming to change.

I lifted #3 last night, no fuel coming out just a slight tic and air pushing out. It was an old hold down and bolt. I was going to wait until I built my motor to get the billet set but I guess I'll order them sooner than that.

Funny how there was a few of these threads to pop up and I lifted one of mine FML.

Just be glad you didn't break a injector or torch a head! You just got a friendly warning! Ask sting what a pushed injector will do in a hurry.

Just curious because I don't know. But how will the head become damaged?

It torches the part where the copper washer seats down and can screw a head pretty good. I was lucky enough mine just torched it a bit and didn't screw the head or injector. 30,000 psi can make for a good torch head.

Ah yea makes sense, I was able to see down in mine looked good.

You guys are scaring me. I've been lucky this long so before I go compounds or add more fuel, I'll definitely do billet hold downs.

Yea can we just stop talking about it. Everything was fine until these threads came up and I lifted another one.

I got mine from gmpartsgiant.com, P/N 11611128, $2.31 ea.

I pushed mine and raced at least one full pass then I had a slow et race I did on it to before I noticed all the blow by and thought I shit a pistons new bolt a good used hold down and still going so meh I'll do billet if I pull the motor for something or I get money to burn on it.

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
