The rear engine tinware on my ‘72 doesn’t seem to quite fit properly, and it is leaving some gaps. As far as I can see, the rear tinware is a bit too far back and it’s causing a 10mm gap around the pulley area. It’s a bit of a strange one as the bolt holes to connect it to front front tinware all line up (and are bolted in), so it could be that it’s a newer aftermarket part which isn’t quite the correct size. You can also see that; - the rear tinware is too far back as it’s tight against the rear frame of the van, and I cannot run the foam seal fully around this part of the tinware - it seems the previous owner modified the rear tinware and drilled new holes/fitted a new tin plate where the hot air hoses go My question is: - Without replacing the tinware, do you have any ideas of how I can seal the 10mm gap around the pulley to help separate the hot/cold areas of the engine. OR will this gap have little to no significant impact in terms of warm air getting in?
The first and only time I did mine, I found that the rear big one married to the head tins the opposite way I was expecting it to - I think it has to slip beneath. This led to the second penny dropping which was to put everything together loose first, position it and then tighten everything down.
The rear tin needs to go on top of the breast piece tin behind the pulley. The V groove drain there should be such that a tinware screw can hide under the rear tin sitting in the V groove... Bend it and wiggle it so it goes over. That looks like maybe an aftermarket Beetle tin with a bit bolted on the back to fit the bus
