I am doing an engine swap on one of my CRD's (225k miles and dropped a valve). I have the engine out and stripping off accessories to put on the replacement. What is the silver line with the green banjo nut in the picture below:

I've posted this before, but here is a picture of what happens when a valve is dropped:

Looks like the line from the vacuum pump.

#13 on the diagram is the bolt and tab that stabilize the other end of this line which mounts to the Flow Control Valve body, I believe.
If you install Weeks 1 elbow kit, it comes with a special L bracket that mounts it to the intake manifold instead.

Jay.... when did you drop that valve?

I also have a block with a #2 dropped valve.

Any interesting in selling a piston/Liner so I can make a good short block again?

i was told that this engine is not supposed to drop intake valve , because they don't run hot , thanks for posting it again , but we are ok now because that guy that made them before is retired already LOL they have somebody else now with young eyes in quality control department

I'm not exactly sure what you're saying, but I'm pretty sure it's an exhaust valve he dropped. Glow plug comes in from the intake side, but the missing valve is on the side opposite of the glow plug. Therefore, exhaust valve.

Racer,

I bought this project earlier this year. Finished harvest and now I have time to fix it up. The previous owner was a poster on here (I think his name was DieselGuy). I was hoping it was just a bad head gasket or rockers but......... Looks like I'll have about $500 in fixing it as the guy gave me a spare engine (100k miles) and head in the deal.

I'll put a liner, piston and rod in the bad engine and keep it as a spare short block. The liners are showing some wear at 225k, but I doubt I'll ever put many miles on it if it ever gets used.

The liners in the bad engine are showing a lot of wear at 225k miles. I am planning on putting a piston, rod and liner into this one and saving it as a spare for my 5 CRD's.

Ok different approach, want to buy a short block with a dropped valve in #4?
