Hello I-boaters!<br /><br />Recently there is a new noise out of my engine when he is warm. It's a kind of a very slight ticking noise on low RPM. It wasn't there before. I am wondering this can be related to the piston rings?? I have 9 till 10 kg/cm2 compression on all the cilinders.<br /><br />I hope these data is normal and the sound is not related to an imminent problem. Has anyone an idea?
