Keith Browning Posted June 2, 2012 Share Posted June 2, 2012 Had anther one towed in popping from the intake. I wonder what it could be? It will be a few days before I can get into this one because we actually have some work in progress now but it's the same every time... worn rocker tips resulting in broken/displaced rockers. This truck is used so the likeliness of a seized valve is very low. In fact, I haven't seen one of those in a long time now. We service this truck regularly so I know it is not neglected.

Jim Warman Posted June 3, 2012 Share Posted June 3, 2012 I have no idea what gawd you are sacrificing medium sized mammals to... but every one of those helicopters I have ever been the proud recipient of have needed camshafts. Quote Link to comment Share on other sites More sharing options...

lmorris Posted June 4, 2012 Share Posted June 4, 2012 Wonder how long it will be till we find out what God Michael sacrifices to... Quote Link to comment Share on other sites More sharing options...
Mikill Posted June 5, 2012 Share Posted June 5, 2012 Lately the poppers have been getting short blocks because of mushroomed lifters,damaged bores and camshafts. Quote Link to comment Share on other sites More sharing options...
lmorris Posted June 5, 2012 Share Posted June 5, 2012 I guess it all depends on how long they let the popping go for before they bring in the truck. IMO most of the fleet trucks here in Alberta stay in the field when they should be in the shop for repairs. What say you Jim? Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted June 8, 2012 Author Share Posted June 8, 2012 Okay, worn down rocker tips. #7 exhaust rocker fell apart. God I love this engine. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted June 9, 2012 Author Share Posted June 9, 2012 With new rocker assemblies on both banks we lost the popping but still have a dead hole on #8 and low relative compression on #1 and #8 and smoke. Looks like after a compression test we are goin in. Quote Link to comment Share on other sites More sharing options...
Jim Warman Posted June 10, 2012 Share Posted June 10, 2012 Leon, out here in the sticks, a truck isn't officially broken until it wont start or move. One of my last "big" jobs was an 08. "Customer states it was running rough and now it wont start" Oil/fuel was weeping out of the dipstick o-ring (a tad overfull), the engine wouldn't crank faster than about 60 rpm even with two cat batteries to boost with. Three obviously bent rods and 4 bent push tubes... it got a short block and a head. While some guys are anal about their trucks running right, others wont bring there's in until they need a tow truck. Quote Link to comment Share on other sites More sharing options...
