In Reply to: Low Ash Oil posted by Cmore on April 08, 2013 at 10:30:59:
It is like this You run what ever ya want , but when ya eat a valve because the oil you got was NOT a low ash then you will know for sure. I use to do a lot of valve jobs on 460-706 gassers and i tryed a lot of different things tryen to stop this from happening . Ate a exhaust valve one evening while grinding feed , next day i pulled the head and did a valve job i replaced 4 valves that were getting thin cut the seats with a three angle cut and hand lapped them in . Put it back together and the following week while grinding feed again she pulled down while were were grinding hog feed and she sputtered once coughed and farted and i saw a red hot piece come out the pipe and she was missing again . I was thinking that well ya screwed up you should have put all 6 valves in , back to the shop and pull the head only to find that it was NOT one of the old valves but one of the new ones had a nice clean torched VEE in the face and one of the other NEW valves was starting . I was talking to a guy from Indiana that was and old I H dealer and he told me that my problems were from the OIL we were usen and yes we were usen the oil that we were usen in the diesels . Well just for the heck of it we did as he said and we switched to the I H low ash and i got all my customers to switch also . Well by doing this i shot myself in the foot as i lost my valve job income that was good for three four valve jobs a year . Ya want to farm with a 706 gasser then you have to play by the rules and they will do what ever ya ask of them , try and save a buck on oil or gas and it will cost ya more then if ya did it wright. So 30 weight Low ash for oil and 93 octane for gas as for the best spark plugs to run in them either C86 A/C's or the 386 Auto Lites Solid copper core ing. wires keep the timing set correctly valves set ( i do ours each spring ) and run her like ya stoll it
