Hello BDA,
this is not an original Bigvalve cover. It is a homemade cover for the 4AGE with the BigValve design.
Hello SwiftDB4,
it is a Spyder driveshaft at which I repaced the doughnuts by joints of a Volkswagen Caddy1 (14D) Diesel. One of the Caddy Driveshafts is a welded one which you can easy modify to weld to the Spyder driveshaft. The flange of this VW Transmission can be easy modified to weld to a shortend outer Spyder driveshaft.
Hello Dilkris,
I made a opening at the firewall for easy maintain the engine. But it would be possible to fit the engine without cutting the firewall. The 4AGE is a very short engine.
Hello TurboFource,
I started to write some posts about my car, but this was some time ago. If you search for "Bastard" and "4AAGE" you should find it. I was very buissy last year and could not write to much. But sometimes I will.
Hello berni29,
yes, the camcover is homemade
