So I've had my Clio 200 less than a year, and its never sounded overly smooth. Had this invedtisgted last week for a service and Mick at diamond motors put it down to a fault pressure control valve. That's been replaced but there is still a loud blowing from the oil filler when engine is running, while this cap is off, the engine revs pick up and sounds a lot smoother on running. Mick from diamond suspects it could be compression ring damage.
So, the cylinders have been tested for compression with the following results, but the question I have is what are the figures from Renault, and has any one had similar issues and got it resolved?
Dry compression: cylinder 1: 150psi 2:140 3:160 4:160
Wet compression cylinder 1: 165psi 2:155 3:160 4:160
Dang anyone clear up wthat this means in simple terms as I'll be speaking to available car (where I brought the car from) and want to have a better understanding of the issue at hand.
Thanks,
Adrian
