This engine is going in an old Land Rover and I have a couple of questions...

This pot is on the top of the injection pump and looks like two vacuum lines go to it. I'd guess it's part of the cruise control (that is not being used in the truck this engine is going in) but I'm not sure. Can someone tell me?



The second question is this engine has a fair amount of oil build up on the side of the block under the intake manifold. The intake was pretty loose and I'd guess this and the valve cover is where most of the oil is coming from but I also noticed a corner of the head gasket is missing. I cleaned it up to make sure it doesn't expose an oil galley, which it doesn't, but it still makes me nervous. Think it's something I need to worry about? I'd hoped not to have to pull the head on this engine.



Thanks in advance for all your help!

Jim

Fuel shutofff?

The tin pot on the back of the pump is the fuel shut off. It's the white plastic thingy on top of the pump that I'm wondering about.

The "white plastic thingy" is the vacuum control valve. Manifold vacuum connectes to the top of the valve and goes onto the transmission. The valve bleeds off vacuum and the transmission vacuum is regulated depending on pedal position.

Thanks Brian! Guess I can chuck that!

Any thoughts on the missing chunk of headgasket?

No way to know until the engine runs again. Either the compression pressure or oil blows out of that area.........or it doesn't. You'll know pretty quick..........

Head gaskets are typically in bad shape on engines of this age. When you see what they look like when they come out of the engine, it's a small wonder that they are sealing anything at all.

Since it's out of a vehicle any way, I would replace the head gasket and seals too!

Yes, I tend to agree........the work required with the engine removed is a fraction of the work necessary when it's installed. Probably have the head off in less than two hours if you work quickly.

there is no way i would ever replace a head gasket prophelactically.

it looks like nothing to me. just a corner they didnt gasket. the head gasket is metal lined on all edges so i cannot imagine how a corner would come adrift.

just me.

Thanks for your thoughts. It was a running engine and though I didn't hear it myself, a good friend did and claims all was well. I think I'll chance it for now and see what happens. And as in my other truck with the 616, I'll carry a full gasket set when I venture off into the wild blue yonder with this truck.

Thanks again.

Why not? The engine is out of the vehicle. It's a hell of a lot easier than when it's in. I'd call it cheap insurance.

it might be easier than with the engine in the car but it is still a lot of work. have you done one?

for me? no way unless there is clear signs of problems with something in the head.

if it aint broke.....

I'm with you Tom. It was a running motor when it was pulled and although it's got a lot of miles on it, doing a headgasket in situ isn't that big of a deal. I'll probably thow a chain at it to be safe and order a headgasket to have on hand.

Another question...This engine has an EGR system on it that I intend to do away with. I know I've seen threads about this before but I couldn't find anything with a search. Can someone point me in the right direction?

Thanks for all the help.

Damn...I was hoping to find the answer on how to get a quick 617 turbo...

Since the engine probably has no vaccum plumbing on it, it's got no EGR by definition. With no vaccum to the valve, it can't open.

If you want to remove the valve completely, I offer a kit to accomplish that. Valve replaced by 1/8" stainless steel plate. Exhaust port closed by .032" copper plate.
