Anybody experienced this? The original piston pin does not want to fit in the new piston I'm installing (too big)... I don't know why the piston bores would be any different but maybe I'll just have to buy a new pin.

you might have the wrong piston,check that please

 

how did you go about burning the piston?...........and how did it act....i never had one burn on me and curious to know...since im pushing 200k.......

what im asking is like details on the viberation and all.....i have noticed that my truck has given a little more viberation then it did 2 years ago but im still feeling good power aswell as decent fuel milage in the 19-20 mpg range.....i just kinda what you can call it worried for my truck because it just turned over 300k in miles just recently and i have so much power going through it and i kinda pushed it very hard when i first got the edge comp box before getting the gauges.......

 

i noticed that mine gives off a little drooning noise from the intake of the turbos both when i had the single and now with the twins.....

 

There are no details to give... one minute I was truckin' along, the next minute I was stopped on the side of the interstate. Sure there was plenty of noise and vibration after it let go, but nothing unusual leading up to that point.

I don't think you have anything to worry about in your situation... but if you're really curious, a blow-by test could give an indication of worn rings. Or pull the head and look first hand.

Something just occurred to me... when I removed the pin from the original piston (the failed piston) I had to pound it out with a hammer while the rest of the pins came out with just the pushing of my thumbs. I suppose the pin could have expanded from the heat during the failure... expanded so much that it didn't return to it's original state...?

Sound feasible?

yeah that does sound feasable......i was just wandering if there was any distinctive things that happen when it failed for future knowledge....im not wanting to pull the head off tell i get the moeny to fire ring it....

 

did you have the rod redone??( the wrist pin bushing is probly scalded) I have 6 used pistons and pins here ,want them??
also comon culprit is the oil cooling jets.................................

 

I only need 1... my orignal pistons are stamped 3709, will yours work?

 

I will try to tell all I know in 3 sentence
1- will work
2- stock size is measured in grades...(deck ht) once you go O.S. there is NO choice for "grade"....so I do not see how its all that important...measure you deck ht or look at your piston,you will find 2 sets of numbers,lower set is" grade"
3 -I highly recomend you have your rod resized....and if you find any little green tubes in the bottom of your oil pan or drain bucket let me know......as ther is a reason WHY you had a melt dwn.......was 4 thru 6 was it not??(probly 6)

 

You already sold me steel jets George...

 

well Ill be ...not paying attn.!!!!!slap me!!!!now you need a piston?????got 6 if you buy one you get all!!
