Scirocco Register

So I've recently got the Mk2 Scirocco back on the road after a 9 year slumber. I'm looking at changing the head so my spare and gone for a skim. I was looking at my Mk2 golf and noticed that the metal coolant pipe is a larger diameter. So I'm going to borrow it off the spare engine and try it on the Scirocco. The only things I notice at the moment are I'll have to retain the Scirocco header tank pipe. I'll have to change the rubber hose onto the water pump. I also notice that there is only one fixing point on the side of the cylinder head where the Golf has one on the gearbox and one on the engine mount. I'm also looking at modifying the "crushed" section by the oil filter to make it the same diameter unless someone knows if it's flat for a reason . Ill let you know.

You can buy new ones?

So having had a look I'm going to change over to the Golf pipe. I need to add the bottom bracket to fit to the engine block by the engine mount. I will also have to warm the pipe up and bend it slightly unless the Golf oil filter bracket is different. Also had the header tank off and what looked like a chamois leather fell out. Looks like it was well silted up. There's also been evidence of that nasty bodge mastic stuff in the inlet manifold rubber to the point that you couldn't even get a pin through it. Radiator change coming up as well and a good cleaning of the pipes. Seems to be a bit of a sludge pit.

I guess someone may of put in something like Radweld ?.... Horrible stuff that just blocks up the coolant system over time.
