Whats behind this on the IP?

Post by Golf/Jetta »

The pump is for a 1.9L - dual stage injection.

I want to know if there is a seal in here and if I unscrew it from the pump will anything fall out. Well maybe except diesel fuel.
I believe mine leaks from here as its wet around and both lower Delivery-valves are wet.

That's the bolt you remove to screw in the dial gauge to set the base timing. I do believe it has either a rubber o-ring or a copper crush washer.

Not the bolt to screw in the dial gauge (coper washer is the seal) but the big screw in nut (three sided socket) (between the delivery valves) that holds that bolt.

If it's like a 1.6, there is an o-ring there.
I do have some pics posted of one I took apart for a bushing reamer alignment tool.
