Thanks for that, but it more the 2x pipes running back towards the bulkhead from the pump/stat housing.

I have removed the oil cooler modine and have no heater either.

IIRC doesn't the Heater connection go to a small piece of rubber hose and then a steel pipe back to the bulkhead???
Any pix's???

what about the Header tank connection? is that just a rubber hose all the way back to the header?
Where's it routed on the cossie in relation to the engine???
