No, it's not that high, it's just that I don't want to deal with it. I would need to get a pump, control the flow and pressure, get the pressure rated hoses and connections, AND get a centrifuge. I like the spinning bowl type ones just because of brute simplicity. Just feed in the oil at whatever volume and let it do its thing. The lower the flow, the more time it stays in the centrifuge, and the cleaner the oil gets in one pass.

That's why you put a thick steel blast shield around it. 

There's no paint on the inside of the crank case on my engine. And I don't intend to paint it on the inside. The last thing I need is to have the paint start to flake off or bubble.

My net was being difficult and somehow it seemed that the first thread didn't post, so I re-submitted it and added more info. Can we continue the thread there?

Thanks.

Well, as some know, I finally made the journey to Lethbridge (7.5 hours one way) to Troy's and got myself a 6/1 and a gen head. Troy mentioned that there may be some sand somewhere on a ledge by the cam. Now how do I get at this spot to check? Remove the cylinder head & cylinder and look down through where the con rod comes through? Anywhere else? Anyone have a picture? I have removed the inspection plate and checked, and I haven't found a speck of sand, and Troy mentioned that these were a pretty clean set of engines. So that's good.

I'll be relying on this engine a lot this winter, and I want to make sure there is less chance of it going wrong.

Beautiful place indeed. 

TDI's only started being sold in North America since '98, so they are not that old. Everything before that was IDI, except the bastard child AAZ engine from '93-'97, that was direct injection but pure mechanical pump. Computer controls also start in '98, before that was mechanical pump. '98-'03 still had a rotary distributor style pump, but was computer controlled, '04-'06 started the PD or "pump injector" engine, injectors operated by a cam lobe, but computer controlled. '09 has common rail. VW also does not have urea injection in the exhaust. That's a Mercedes and BMW thing.  VW uses sophisticated catalysts and re-gen cycles to comply to emissions. In the '09s you need to use ULSD or the catalyst will die. Except you can't get anything but ULSD at the pumps anymore.

With that said, making a 4 cyl run on 1 cylinder will make it die a quick death. Run all 4, or get a single cylinder engine.
