Completed: May 15 2001. Constantly undergoing further modification.
Comments: I had a few oil leaks. The block round the rear seal is quite sharp and I accidentally took a small slice off the neoprene seal which caused a leak. The up-rated oil pump required 2-3 extra pounds of torque to stop it from leaking. D&D's swivel oil filter adapter leaked until I applied about 60 pounds of torque.
The 1969 Rover engine has a pipe at the back of the block which vents the lifter gallery. This pipe actually spewed quite a bit of oil down the back of the motor ending up dripping from the bottom of the tranny looking like a rear seal problem. The solution was just to block this vent off.
I had cooling problems and installed ductwork to force air though the lower radiator. This helped, but it wasn't until I installed louvers up high on the inner fender into the low pressure wheel well (see photo) that my problems were totally solved. The car has no overheating issues now, even in city driving in 100 degree temperatures. You've got to get the heat out of the engine bay.
This car is constantly undergoing modification. Every winter season I improve, repair and replace. This winter will see new VDO Gauges installed. Winter 2007-2008 will see Dodge Omni flares, Fiberglass bumpers, stainless steel grille, side molding (chrome strips) removed and filled, sidelights removed and filled, new tires and mag wheels, and I am already checking into a Rover 4.6.
