Chas Occasional Poster Registered: March 2004	Re: Run-in (or break-in) method Wed, 31 March 2004 08:17 If you read the literature that comes with the rings you will find out how to run in. I have actaully spoken to a ring manufacturer's guru and this is the basic procedure: Use mineral oil; Get engine up near temperature on fast idle; Don't let idle too long nor rev the engine while stationary; The idea is to build pressure behind the rings to get torsional twist and the scrapers working; Take out on the street and get up to 80 kph and ease back to 50kph, while in top gear flatten the accelerator and get back up to 80 kph. Do this five or so times (an incline is a bonus); The rings are now bedded; Take home and change the oil and filter. Resume normal driving or dragging Note top gear as in forth or fifth Note if you have changed bearings you need to be a little careful about redlining for a few miles. I have used this method many times and after 30k head inspections, the bores are in great shape. [Updated on: Wed, 31 March 2004 08:19] [Report message to a moderator]
