I love the "Vehicle Overspeed" that popped up lol, I dont think my is fast enough to set that alarm

 

actually the vehicle overspeed thing is just a message that pops up after 70 miles.. i guess those are only fitted in export vehicles

 

running into a little problem, on a cold start i see greyish smoke coming out of my exhaust for a few seconds then goes away, i revved the truck and nothing.. drove it for like 20 miles then turned it off started it again no smoke. parked it overnight and started it in the next morning and i could see the smoke again, so its only on cold starts.. its probably the valve seal thats causing all this.. i hope the rings are alright the short block is only 400 miles old

 

Truck sounds FANTASTIC! What a way to have your brand new truck, just like you like it!

 

Bad news turns out i have 5 thou piston to wall clearance idiot engine builder.. i read that its alot for a forged engine, any effects on the engine? The only way to fix stuff is to get bigger pistons i guess.. im at 4.070 now

 

Old dragsters saying - "Loose is Fast"

 

My 6.0 took some piston damage for the same reason. Old school engine machinist using techniques that 'old school guys' use. And it was very expensive. Can't put a price on stupidity...

 

what's the clearence supposed to be, if not .005"?

just curious cause i don't know.

 

Clearance specs are set by the piston mfg. it varies with piston design and material used, mahle pistons typically have .002-.003 clearance and custom pistons like J&E and Diamond (2618 material are usually around .004-.005, turns out my piston should be at .005 i double checked with the manufacture today

 

So you should be good to go then right? Im guessing you thought it needed to be a little tighter?
