I got my 16v flange from him and it all match up well.
Cheers mate, very affordable until they chuck the $105 postage on top ?
Ex850R If you are careful enough with the plasma , centre pop the lines all the way around its easier to follow . go inside these lines to rough it out then Dremel out the rest of the way you can learn a new skill doing it yourself.
Thanks for the centre pop idea, that's great. I usually mark with a sharpie but once the metal gets hot it tends to go pretty faint.
Today I did some of the maintenance. Replaced the top and bottom radiator hoses and gave it some fresh coolant.

There was a lot of rust in the top tank so I flushed it out with water. I should have bought some radiator flush to do the rest of the system but that will have to be next time.
I also replaced all the fuel hoses in the engine bay

No idea what's going on with that hard plastic feed line-brass adapter-rubber EFI fuel hose-fuel rail setup... I'm willing the bet that's not standard?
I also replaced the rear washer pump which wasn't working at all.

The pump spins and loads up (yes, I have it going the right way ?) but no water comes out the rear jet.

Looks like there is meant to be some sort of nozzle attached here, and I have to find out where the line is kinked or broken to get the rear sprayer working.
I'm beginning to suspect the car has a blown head gasket, it's blowing faint white smoke out the exhaust while idling, and I thought I saw some smoke come out the expansion tank when I was bleeding the system and warming up the car... we will see. It didn't smell particularly sweet so it could have just been condensation, but it's not a cold day.
