I have what sounds like an upper engine noise, but I am not sure. It is a 1983 Air Force M35A2C That has not had the truck or engine rebuilt as far as I can tell.
It shows 11500 miles and 375 hours I don't know if this is actual or not. To give you the history that I know I bought this truck nonrunning from someone who had two of them.They removed some parts from the one I bought to get the other one going. I was told they swapped the electric fuel pump and that was all it needed to run.
Actually they swapped the pump, took the brakes and wheel cylinders from two wheels. It also was missing a bed and two rims and tires.I bought it knowing all this and
the risk involved with buying a non running truck. What I have done to this point is new fuel pump ,cleaned fuel tank, changed fuel filters,new air filter and two injector pumps, it did not run right with the first one I put on. I am in the process of A3 brake swapp and trying to find the source of the enging noise.I have tried to convence
myself I will deal with the noise later ,but it bothers me knowing it is there and I can't seem to get my mind off of it.The truck starts better than any vehicle I have and runs good and strong. It just sounds like it has a valve way out of adjustment. I have adjusted the valves they were fine and I have pulled all the injectors. I did not see anything that looked bad. I have listened all over the engine with metal rods, screwdrivers, wooden dowels and can not pinpoint the noise. I also pulled the flywheel inspection cover and did not see anything there. On the passenger side of the engine at number 6 there is a small amount of oil sepage from the head gasket and you can see the oil move a little while it is running ,but you can not feel any air comming out. I have felt for exhaust leak and did not find any. I have searched this site for common problems like this and was not able to come with much there. I am to the point of pulling the oil pan and heads to look inside. I have a few short videos and maybe someone can point me in a direction I have not thought about. I have a rebuilt in 1974 LD 465 that has a LDS 465 turbo on it that I pulled from a
parts truck. I dont want to use this engine unless I have to I would like to fix the other one as it is a TD block.
Thanks Jim
