Well my truck lasted till the end of school. driving home on grad night it started to lose power and started making the classic rod bearing knock.

Dropped the front diferential today and pulled the oil pan in order to change the rod bearings. while digging through the silvery gunk that was left in the pan i found these. any idea what they are? or how screwed my engine is?


here they are clean

the first pair

iPirate

here's the other pair

its a 93 22re 4X4 btw

barrel roll

almost want to say a ring

flecker

Oof! Looks like thrust washer/s to me.

See if you can man handle the crank back and forth. Sorry- bad joke. Seriously though....

iPirate

ok that solves that.....so how screwed is my engine then

flecker

The engine may be ok in the cylinders... the crank is gonna need to be turned and polished at the least if it moved a bunch!

Not a good scenario there man....

Might look into full rebuild. That isn't a cheap fix.

How many miles on the thing now? They typically don't just fall out, what hapened exactly?

Yeah... the crank might be salvagable. Only way to tell is look at it. Did the engine sieze?

Hard to tell what shape the engine is in from oil pan pics. Sorry.

PismoJoe

Those fell out on their own???? Man I hope your crank is still savable

annoyingrob

I had a set fall out once, but it was helped by a 3200lb pressure plate.

Years of abuse and improper oiling can wear them down (notice the score marks) can cause them to slip out under certain conditions.

You need to pull the crank out, and examine the block and crank surfaces between the thrust washer locations. A machine shop might be able to polish them, but chances are you'll be looking for a new block/crank.

iPirate

the first pair look really worn, while the second are just bent. if i remember right, the lobes on the crankshaft look kinda like the first pair. i'll go look again in the morning.

how much am i looking at for a rebuild if i do it myself?

flecker

If everything can be machined/ saved... the typical is between 5-700 dollars for the machine work and a master kit runs roughly 3xx, so between 8 and a grand if you do it.

OR, you could hit the yards for a donor and work with that for much less, maybe surf craigslost for a used one.

Lots of options at this point, running that motor isn't one.

PismoJoe

Probably right around $400 for the machine work + hot tank, depending on if your crank is usable (hopefully it is) then you need at least rings, timing components, gaskets, and a new bearing set. Maybe around $1k if you don't get carried away like I did

PismoJoe

Hey flecker beat me too it lol but I have to say nice figures there fleck!

iPirate

It has somewhere around 300K on it. The engine started making a knocking sound when i would accelerate a little, or when i let off the accelerator, being the last week of school, i didnt have the time to try and figure out what was wrong with it, and hey it still moved right. on the way home from graduation i lost a lot of power, noticed the oil pressure dropping, and it started to make a new noise (rod bearing). I towed it the last mile and started to work on it today.

the engine turns over fine. the car will even drive, but it doesn't sound nice and probably isnt very good for it.

I'll take some more pics in the morning.

toynado

with no thrust bearings the crank's probly wapping around in there sumthing fierce
i wouldn't run it
parts can be dangerous when airborne
i wouldn't wanna be sittin there if say, the flywheel came apart

PismoJoe

I wouldn't want to be the clutch if the flywheel came off

I kid too

But yeah, don't run that thing.

toynado

i've had a clutch fly apart while i was sitting in my car
twice
can be pretty scary

but when the tranny blew up on the freeway
the dog jumped in my lap and was hanging on for deer life and i couldn't see the road
bwhahaahaaahaaa
felt like sitting on a bomb
sorta
