I'm more interested in how you got a DOHC motor in there. Is it a duratech swap? Or a Volvo head conversion? Sounds very interesting.

WE cant help you out until we know what motor is in there. I'm only familiar with the stock 2.3L SOHC engine, but would love to have a duratech in the fox...

Agreed. Did you do an engine swap or did you mean SOHC 2.3L? Anyway, this could be a multitude of problems. Anywhere from failed engine internals, to a cracked flywheel, to an automatic transmisson issue. But, if you did lose oil pressure, I would say it is the engine. Your tachometer issue is a failing ignition module or bad tach. Replace the module first. It's a lot easier.

I'd try checking the oil...
