3.6L Variocam in a '99? Not an easy proposition due to the fact that the 3.6s were driven by the 7.8 version of the Motronic DME.

It's easier if you start with a 3.4L E-gas car, which used the 7.2 Motronic so at least the connectors physically mate with the 7.8 DME. Then all that needs to be done is to move a very small number of wires in the DME connectors and add a couple of wires for the Variocam control back to the engine.

But in a '99, which wasn't E-gas, the connectors in the stock DME loom won't even mate with the 7.8 DME, so you're looking at a lot of hacking to make this work.

Regarding cleaning an oil-fouled 996 cooling system, it's messy but pretty easily done with enough flushing using a mix of liquid laundry detergent and hot water. Avoid any foaming soaps or degreasers as they are not nearly as effective as a non-foaming detergent.
