The only new parts i fitted were an oil pump, sump baffle and clutch friction plate. I fitted an new oil pump as the 16v heads need lots of lube; the plastic sump baffle broke (brittle plastic clips) and the new friction plate was because the 8v gearbox has different splines to the 16v box...this last detail i discovered after putting it all back together, fring it up and trying to find a gear...crunch!!
I think the 9a/6a engines are actually identical but the inline Audi mounting means the sump, oil cooler and inlets are different hence giving it another name!
All i did was swap the sump pans and rotate the oil cooler by 90degrees and everything else just bolted in place.
As for the cams i swapped both as i couldnt remember which one was differentÂÂÂ

Never had torque steer before in a Golf!
