So you get a rattler??? Who cares, it will still make over 300 hp at the treads and get 30 mpg on a trip.....
Seriously though, I've tuned a lot of cars and I've only come across one "rattler" (it still made as much power as any other motor).
The
oil-burn problem due to weak ring tension (they tried to reduce friction by reducing ring tension, to improve fuel economy), was rectified by increasing ring tension (obviously) in later models.
To be honest, I don't care what people say about these motors. My ute runs 11's and still gets 10L/100km on the highway..... how many engines will do that???
