So driving to work today I notice a sudden increase in valve noise on decel.
It only seems to be coming from one side and possibly one valve. I had a top end rebuild in september, new guides, valves and seats, after dropping a seat. Not as capastophic as some pics I've seen, but it did nick one piston.
Question is: What does a broken ring sound like? If they do sound. And, do seats 'unseat' a bit and make noise?
I've detonated a lifter before so I dont think its that. Just sounds like one valve is suddenly out of adjustment a bit.
Any help on diagnosis is appreciated.
