I had clicking in my 79 RV with a 400 Dodge motor. I took the intake manifold off & checked all the valves & also took the valve covers off to check the rockers. All was good except it had sludge all in it. I took it to a local mechanic that does work at his house & he said some of the piston rod bearings were bad. He replaced the rod bearings, the crankshaft(it was damaged because of the bad bearings), the timing chain, water pump, all new gaskets, plus put in a new master cylinder & bled the brakes all for $1,400. A hell of a job I could not do myself. He did say he removed the oil pan to get to the rods & removed the front of the motor to get the crankshaft out. The motor used to click really bad but since all this was fixed 3 years ago, still running like a champ.

Over revved engine usually damages the Valve Springs and/or the lifters.. first thing to do is have those replaced (easy, in RV, job), UNLESS a tech tells you it something else, of course..

As for the generator... : Onan Generators - SmokStak

I had a master rebuilder here in town look at it jsut an hour ago he thinks its ither a headgasket or a rod thats makeing a hiss sound but not through the carb or exhaust. So i have to take the oil pan out and see then the heads off if all looks good in the oil pan. I remember have to do that on an older dodge 440 i found a rod bolt in the pan yet all the bolts where their.Ill post the findings and so far from what the rebuilder says i did not evan notice that sound befor it was the rattle but if the engine is on low idel it runs smooth. So im hopping it wont be to bad of a fix. Will keep posting as i get along on this.
Thanks to all who have taken a active part in providing so much help!!

Hopefully it was nothing serious. Make sure you perform the field tests on page 47 before disassembly.

Have you changed the oil to a little heavier type older engine to have some bad clearance issues. Mine prefered 20-50 and ran quite and smooth for 4 years after I learned to go heavier. You should aslo be able to get some info from fleetwood. They sent me the original owners manual.

I'm lost? Rods dont make a 'hiss' sound...?

If you can run the motor under light load (in gear, foot on brake, tad bit of throttle) and hear nothing, then the rod bearings are prolly good. If you hear a knock, knock, knock then you have a bad rod bearing. If you get the RPMs up and hear a rattle, then it most likely is one or more of the lifters. If there is a tick, tick, tick at idle and above, then it is a spring. If you hear a tick, tick, tick only at idle, then it is prolly a rocker or sticking valve..

As always, there are other things that cause these noises, but these are the most common.

Still looking into it, but cant get to it this weekend. Ill try for monday late after work. Ill pull the pan and see whats going on underneath. If that does not show any thing wrong ill do a leak down test to see if it the headgasket piston valves ect.

Thanks for the advice and have copppied that quote as it does give alot of good info !!
