Guys,
Today, ordered a cylinder head gasket and was asked whether or not I needed the early, or late style water porting.
I checked, and discovered that my car, which runs a D42 motor, is fitted with the earlier cylinder head.
I read a thread recently, regarding that extra water port at the front of the engine and I was amazed to see that, in my car, the block has the water port and the head doesn't.
I've had the car three years and not noticed.
I've also run it for thousands of miles - no problems.
My guess is that someone must have capped that port on the block.
I'll find out for sure when the head comes off.
It's crazy, the stuff you can find on old cars!!
