i dropped my oil pan today to r&r the gasket (leaking) i was surprised at how clean the inside of the pan was no sludge at all . problem i did find was a metal c clip about the size of a quarter . i am not fimilar with the fe engine anyone recognize this ?? the wing nut is there just for size reference.
thanks in advance
mike

 

oh other thing i saw was lots of back forth play on the rods , is this normal ?
and timing chain has probably 1/2 slack .
looks like a rebuild is in my future (near future)

 

Ya might want to post that on the FE forum. My thought it is a broken something not a clip.

i posted in the fe section too , a member said it looked like a broken piston pin retainer .
guess my engine rebuild is coming quicker .

 

i smell a troll.

 

Soooooo, where's the other half? If you are lucky, it is still holding the piston pin in place. If not, the pin maybe wearing into the cylinder wall.

 

SMELL A TROLL ?

 

Question
does the piston travel down far enough to let the retainer fall out ? i am thinking no
so how did this get there ?or are the retainers on the inside close to the rod ?

 

Well thats not good, like John already said thats a wrist pin retainer! I lost 3 of them from the improper install at machine shop. There is a rounded side and a square cut side and they must only go in one way. Good news my engine ran for almost 20,000 like that made a lot of smoke towards the end and ruined the block as it cut perfect lines deep into the walls but plan on a rebuild soon.

 

my truck does blow smoke , thought it was just valve seals needing replacemet.
guess i'll crank engine over by hand and see if i can see and cylinder wall damage.

 

deff piston retainer as for how it got there gravity at its best... i agree with mike it'll run but for how long is the question

 

According to this thread you shouldn't be driving the truck.......

The broken half moon shaped piece could be the part of the wrist pin retainer clip, but peeps find all sorts of things in oil pans:

Old drain plugs, drain plug gaskets, engine oil dipstick tube o-rings, dizzy drive shafts, nuts and bolts.

 

Mike, take that piece to a motor rebuild/machine shop and see if they can match it up. I'm sure they can figure it out but I think you already know what it is.

 

i checked the cylinders number 1 on pass side wrist pin is out and damaging cylinder wall see pic .
