Re the Type 3 cooling tins; I follow this VW mechanic on Youtube, username Mike Fn Garage. He recommends them. He says that they give him great results. About the Service Bulletin by VW his theory is that the factory didn't want to admit a design error in the original design of the tins so as to prevent replacing engines in warranty.
Was looking for something else and found this thread. The guys says they give great results- did he put a set on, found the engine still ran with them so his backyard expertise consists of "Yup- they run reeel good!" or does he present data (head, air, oil temps) to substantiate his claim?
I know I sound like a sceptic, but you know how it is- look hard enough and some idiot on the internet will tell you anything you want. The type 1 cooling system worked on millions (literally MILLIONS) of stock engines and continues to work on I don't know how many thousands of modified engines to this day. There are a few who have claimed good results with using the type 3 pieces (with modifications) in place of the type 1 cylinder bottom and sled tins when the sled tins interfere with an exhaust's primary tubes. The spent cooling air aims straight down and exits right under the engine, though (not out the back of the car like the sled tins do) and the preheated air can then be re-ingested by the engine in slow/stop and go traffic. It's not the perfect solution.
Great info there. Like I said I don’t know the guy personally but it seems he has many years’ experience with VWs and seems to know what he’s doing. You can check it out for yourself:
