I recently picked up a 06 300ex for 600 running but it has a loud tick in the top end. I originally thought it was valve clearance but I adjusted it and still did it. I happen to run a leakdown test and found that the intake valves failed so I just redid the head with new valves, seal, springs, timing chain, and cam since it was alittle worn. It still makes a loud tick, is this something normal for these engines?
