mackcx Posted September 15, 2009 Share Posted September 15, 2009 So my uncle took decided to purchase a 2001 cx with the heads to the engine missing. He took the engine apart to see why the previous owner would take the heads out and noticed that every single roller alng the camshaft was busted. The camshaft also looks shot to crap. Does anyone know what would cause the this to happen or has anyone experienced anything like this?? Thanks, Danny Quote Link to comment Share on other sites More sharing options...

Thanks, DannyIf you're lucky and the dealer likes you can get the cam changed under policy, they replaced mine last summer with 650k on it, i had to pay labour and gaskets! but with the heads gone, Im guessing you're beat! and remember when you hear the pop'n under the hood shut it down and save some cash!

rhpaulin309 Posted January 20, 2010 Share Posted January 20, 2010 What kind of additives should be used with this low sulfer fuelI have used Howes Meaner Power Cleaner,the small bottle. It costs a bit more than than most but it si my favorites.Engine runs smoother with it. Also noticed extended life on injector nozzle. I live in southwestern Quebec,Canada and the refineries will put out a winter formula around mid october,what i call -40c diesel,even though the outside temperature still reaches +12Cel.in the afternoon.That fuel is great for winter but in warm weather i can tell just by the soud of the motor that i have caught a batch of -40 fuel. This said my 99 E7 still developped fuel seepage at 920 000 miles at the unit pumps, probably because of the unit pump O rings.In any case taking regular oil samples would be a good investement if you plan to keep your truck for an extended perido of time.I have seen quite a few different fleets bring in their E7 for fuel contamination in oil(more than 2%is abnormal)that is why i am ringin the alarm bell.
