I have now fitted the new Z20LET after my old one died due to a faulty oil pump (and my ignoring the oil light!).
What is the running in process, the manual states things like only using 3/4 throttle and proper use of all gears etc for the first 600 miles.
Do I need to change the oil at some stage, is it at 600 miles?
Any advice on the best running in porcess will be muchly appreciated, I do not want this engine to go the same way as the old one.
