I have been trying to get a GMC 455 running right. I finally obtained a timing light and found my timing was about 16 degrees TDC at idle and parked. I reduced it to 10 degrees as a starting point and decided to see if I had air escaping thru the oil fill tube (compression issues perhaps) and heard some slight noises. Is this standard noises of the lifters and rods going up and down? The coach has 135k on it and the cam shaft is slightly worn. I hope it isn't something way down the engine that is ready to blow! Thanks for any input veterans!
