Oil consumption

[peterg]

My specialist reccommends a rebore with Cosworth pistons at an estimated cost of £6,400 assuming no other work is required.

In between the car has been doing about 400 miles per year and has had 4 oil changes, hence I didn't notice the oil consumption although I thought it a bit low last time.

While I'm thinking of it on the trip to Germany the car was run at 3,200 - 3,500 rpm (65 - 75 mph aprox) at mid 20's c. and the water and oil temperature rose to 90 o F. (oil about 5 degrees lower) with no oil cooler. Fuel consumption was between 24 and 31 mpg.

The engine ran smoothly but was rather lumpy at tick over speeds (5 -900 rpm)
