Head gasket job, now valve job

[mhuppertz]

Pulled the head to do the gasket and studs, found some hammered valves. Took the head to the shop today, should have it by Wednesday afternoon. Taking the rocker pedestals in tomorrow for milling. I made the idiotic mistake of taking apart the injector lines instead of pulling them off with their brackets attached, so I am dreading trying to get that bundle of snakes sorted out. I knew better...
Anyway, having major truck withdraws and hope to have it back together with studs in this weekend.

I did that to when i did mine, wont take as long as you think

[mhuppertz]

That's good to hear.
I felt me age wrestling that big chunk of iron off the dowels and out of the truck. I think I will use the hoist to put it back on. My back still hurts!

[skilletky]

the head dont feel that heavy until your sitting in the engine bay trying to get up out of there or put in back on without tearing anything up. that and torquing the studs/bolts can wear out your arms if yer a wimp like me

I'm taking the hood off and using the hoist. I might be about to muscle it on there without the hood, but I just can't chance ruining an expensive head gasket.

What does it cost to rebuild 12v heads usually?

The Cummins engine shop manual recommends using a hoist to remove and install the cylinder head. They usually get it right...

I got the head off be myself without a hoist, and put it back with the help of my son. Easier with studs. And I aam 52.

I had one done last year. Replaced 11 of 12 valves. The bill at the machine shop was $315.

Why not go all the way? What's one more valve gonna cost?

My machine shop did that very same thing to me twice and I shut It down. I told the dude that if so many are bad now,what keeps the others good after you complete the job. Last thing I need is to explain to a customer how I have to go back after 6months of running cause the machine shop left one or two old stressed out valves in it. Then again there's no guarantee that the new ones are any better

Update:

My new head is working perfectly, the truck has never run better.

The shop didn't call and ask what to do. They replaced the bent ones and left the one good valve. If they would have called. The other one would have been replaced.

Glad to hear the truck is up and running Mark.

This has to be the most commonly heard problem with machine shops, today, or 30-odd years ago when I started to mess with engines.

These SOBS will only do what THEY feel is necessary!
Sometimes you ask them for the simplest thing and they go way overboard and ding you up the ass, other times they cheap out and don't inform you and it bites you later, then when you put them on the spot, they just shrug it off and tell you to deal with it.

The last machine shop I deal with told me they couldn't tell me how far a couple of Cummins blocks needed bored until they honed them
Then the damned guy STILL wouldn't say how far they needed bored after he was done with the hone job, so I wasted money for something they didn't need to do anyway.

Bodymen and Machine shops, very few aren't lazy.

Yea new valves were only $9 each. It wouldn't have broken the bank. I told him I wasn't happy about it. I wasn't going to leave it for that valve. We had the head off of Jeremy's W350 all ready. The block was ready for the head. Thirty minutes later the head was being installed.
