Recently purchased a 2001 VW MK 2 Caddy Pickup and beginning restoration on it. The engine is leaking out of the heater plugs must have been previously cross threaded. The engine is a bit underpowered for a 1.9D, so I am wondering is it possible and how complicated would it be to fit a 1.9 turbo diesel 110bhp non-pd engine. Also thinking of fitting a Mk1 caddy front on the pickup what would I need to change to make this possible. Thanks
