Help me find replacement engine valve

[krush]

Started my new job, can anybody help me out? I need a replacement valve:



Here's another angle



I need one of these too.....jk

[saltshaker]

did you try NAPA or Pep Boys?

I've got a couple of valves from an Enterprise that are 6-1/2" across. Every once in a while I'll bring one to a machine shop and ask them if they grind valves. The look on their face when you plop that on the counter is priceless.

Yes, I know, not as big as Krush's, but you can't hide his behind your back. Kinda ruins the surprise. ;D

I've been trying to get a big valve like that to make a coat-rack out of. It'll go nicely with the inconspicuous 36" piston ring next to the counter.

I want pictures of the piston ring next to the counter. Is that at home or on the boat? ppat

It's at the shop.

Here's some pics of the junk collection:

The ring, and a piston from a Worthington Diesel Generator. For scale I put in some blown pistons from a Mack and a Chrysler Hemi.

The Worthington piston is behind the counter (Had to move it there, too many people mistook it for a garbage can) so it's not really obvious at first. When people see it they goggle, next I tell them if they think that piston is big.... then I direct them to the ring which is hung on the wall next to the counter. That reaction is worth seeing too.

It's funny that when you work around big shit for a while you just get used to it. After working in power plants for a while, whenever somebody says 100hp is a "big" electric motor I just laugh.

[Avenger]

Yep, same as when guys on the HOF refer to their "Big" Detroits.

So what are the valves from. Sulzer, B&W?

Water emulsified oil... Nox reduction?

I've heard of this be shilled as a fix for automotive emissions but most fuel injection manufacturers cringe at the thought of deliberately adding water to fuel.

Well, it's big if you're the one paying for the juice.

You know, on re-thinking this, to be fair most people don't get to see things like this, and frankly don't even know it exists. I'm sure the first time you saw a really big engine you were impressed too. I know I was.

Since I started in this business at a fairly young age on a lot of jobs I had to try to act casual like I'd seen it before which I actually had, but I looked really young and you know how ornery "Old People" get when they think some kid is going to tell them what to do.

But I'll admit I wasn't able to keep a straight face when the Chief Engineer on an 800 ft. container ship was telling me about sea-trials when Sulzer had the engine idling at 19 RPM.

They play the water injection game on the gas turbines too (LM2500 and frame 5)....evil nox, go away LOL. I'm chasing a small nox problem with 6 4.4mW CAT's (I forgot model number). I'm gathering data and interviewing now LOL.

I'm still young and an engineer...two things that can get one in trouble around plants. But when I show operators/mechanics my dirty fingernails, they usually open up!
