pflaming Posted May 10, 2017 Report Share Posted May 10, 2017 While listening to my truck engine run with a new friend, I commented on my engine noise. I said I think I hear a slight whine, do you? Hr put his hand on the timing chain cover and asked if I had put on a new chain,I replied "no, it met recommended play". He then said the last half of wear is fast, old school mechanics nearly always changed that chain, which he thought was the cause of my engine noise, not the fan as I thought. Any thoughts on this?

Mike36 Posted May 11, 2017 Report Share Posted May 11, 2017 Loosen fan belt, then start it up for a short time. Will let you know if it's the fan making the noise. 1 Quote Link to comment Share on other sites More sharing options...
pflaming Posted May 11, 2017 Author Report Share Posted May 11, 2017 It has a six bladed fan, the engine I just bought has a four bladed fan. Will swap and compare. Still curious about the chain. Quote Link to comment Share on other sites More sharing options...
