valve train issue
just recently had a rocker arm bolt break off on intake valve. The diesel shop where i got it fixed said that they highly recomend doin the heads because of high build up of carbon deposit. My regular mechanic said he has done lots of 7.3 where they break a pushrod and they just replace the pushrod and keep on truckin.One particular job he called the stealership to check stock on pushrods and dealer had like 1500!! Truck has 380,000km and just wonderin if anybody else has had similar issue.
