1970 bay tinware ..is it important?

[celticbod]

can anyone who knows tell me how important the tin ware and seal are that goes around the engine bay and the one over the gear box. my van came back without the gear box one so is open at the front? it is in a 1970 bay.
and is the tinware different to a 1972 bay?

does this matter apart from all the rubbish that will get thrown up into the nice clean engine bay?
also any one got pictures of the roof struts on a 1970 westy roof?
where do they fit on the roof?of the van is it actually on the roof or on the lower part of the sunroof opening? and whereabouts in relation to the rim etc.?
help appreciated.
more questions to follow too im afraid.

Very important, and what engine have you fitted makes a difference? the 72 depends on what engine its for....

SP/TP/T4

cheers mine is a 1600 twin port and is the engine which was in my old van. went to a resto yard to have it transfered over and came back with no tin wqare over gear box?
make any sense at all?
cheers

 

[celticbod]

had the tinware in my old van(the 72) with the engine. so was there to be fitted if it would go into a 1970?

The tinware is vitally important to the running of your engine.

Without it, it will overheat. Even if it doesn't show signs of it, it will be running too hot somewhere.

Every bit that VW fitted was important - otherwise they would have removed it as a cost saving exercise :roll:

The tinware from a '72 is different from that of a '70 - they have different engine bay compartments as the '72 can fit a larger type 4 (1700/1800/2000cc) engine without modification.

Bear in mind that if you have a twinport engine in your '70, you will need the '71-only piece of tinware to go over the gearbox.

Make sure you have ALL the other bits while you are there, too. Every little helps

thx , thought as much . will have to keep record of missing bits and will all be useful as there are many things not right on the van . will be pestering to know what does what etc, and why they would have been left off.
any other comments would be great ...i have no tubing from the engine to the holes in the tin ware, ...i have no tube from the top of the air cleaner to the top of the carb....
are the heat exchangers the same on both years and the connections to the dash controls? would they need a bit "welding on" to attach them?
.
cheers

much appreciated

Again, without the fresh air pipes from the fanhousing to the exhaust/heat exchangers it will overheat.

Without the tube from the air cleaner to the top of the carb, the air cleaner won't be doing anything at all. Keeping an eye out for a secondhand one would be a good idea, but ones that have not split come at a premium.

Heat exchangers are the same both years, and connect to the control cables via small nuts/clamps similar to that used for the accelerator cable in the carb.

Any pictures of this engine?

 

[celticbod]

cheers for info , cant seem to get the pics to load into photobucket....yet. they will though asap. many to show and ask about . so not good for the engine then with bits missing. the big tubes from the heat exchangers to the heat pipe are also not on the van ? important ....apart from it being cold !!! or colder!!!!

the carb had nothing on the top of it at all so could the engine have been tuned up when it was put back in without all these bits?

many thanks for checking these thread out to all .

Dont think anyone tuning it would leave the carb un filtered as the potential for damage to the carb barrels and heads is huge.... bits of grit, screws etc.....

by the sounds of it mate your "restorer" is a bit of a ****.....(mind my french but theres many of them out there)....

.
maybe not his best work to date is all i can say , but need to know the tech bits so i can tackle the issues .
thanks for all help .
cheers

Hiya Celtic,

I'm coming into this thread a little on the late side but I did want to get my two cents worth in...............

The tinware and seals are crucial. They are the main components of the cooling system for your engine. Would you run a conventional watercooled engine without a radiator? Of course not, and running an air-cooled system without the tinware is just as bad.

AND............make sure you know every piece of tin that's supposed to be on that engine and make sure you have it. Some of the pieces are smallish and very easy to overlook. For example, there should be a squarish piece of tin fitted directly underneath the cylinders on each side of the engine. This tin deflects the cooling air around the cylinders to make sure they are evenly cooled. Without this little piece the cylinders will develop hot spots and you'll have oil and ring failure in rather short order. The trouble is that because of this piece of tin's location it is VERY easy to overlook.

Best advice is to get a diagram of the tinware for your engine and then go out and secure each and EVERY piece.

 

[celticbod]

thx i will have to check that area too....should be there but it seems things are not quite up to scratch ....
cheers.
will no doubt be asking more very soon.

 

[celticbod]

is haynes the best place to get such a diagram etc.
must be something on web too
i will go looking as we speak
cheers

I believe VW Heritage have a reasonable exploded view...
