Why is it noisier ????
Hi guys, why does my engine rattle more when it is hot. When it is cold, the engine sounds fine and pretty quiet. Once it's hot, there is a nice tapping sound. Sounds like the valve clearances maybe. The thing is, when cold and at higher revs the engine is still pretty quiet, but when heated, it sounds a bit thrashy.
My oil is 10/40 and was changed about 1500 miles ago.
Any suggestions recieved warmly (unless they will cost me money)
