Thnx Giles .
I will post them up,hope you can give some more info.
Here is what I came across when I took the head off.
Doesn't look really healthy to me. I also noticed the headgasket being blocked on a cooling hole
Pic I took of the blocked headgasket.
Some of the blocked coolant passages are apparently by design.
Here are a couple of IDI-VW diesel head gaskets:
The top one is a 1.9lTD (AAZ) multi-layer-steel (MLS) head gasket, made by Elring. Good stuff, if you've got a hydraulic-lifter TD (or willing to adapt it to a solid lifter head like me
The bottom is some sort of fiberous gasket. I'm pretty sure it's for a 1.6lTD w/solid lifter head.
The earlier VW diesel head gasket (1.5l diesel) had much more "open" coolant passages, IIRC. There must have been some reason the VW engineers redesigned the coolant passages when they changed the design to the 1.6l motor, I would guess it would have to do with making the relative temperature of the head more even. Notice the extra little coolant passages in between the cylinders on the 1.9l that are not present on the 1.6l or earlier blocks.
Well I can assure you that mine are not blocked by design .I have a hydraulic lifter head and these passages should be open. A few passages at Cilinder 1 are blocked aswell on this headgasket.
