Got the pan off of the capris engine just now, and am not liking what I found.. here are the pics:

What the hell are these little broken round parts?... :toilet: there is no visible damage to anywheres in the motor that I can see..
your oil pump went boom!
from the outside, the oil pump, looks brand new... (it is... WAS)
Appears the "junk" got into the pump and locked it up, twisting and breaking the drive shaft... I've seen similar looking lash caps(fit over the valve stem), but I don't think that's what those are...
The little flat "arced" pieces look almost like piston rings... OUCH!!!
Move each piston to TDC and inspect the cylinder walls...
What happened? Did it start making noises or did you just open it up for fun?
im guessing with the pump shaft a twisler it prob had no oil pressure
No those aren't piston rings,to thick and not the right arc.
Looks like all parts of the oil pump.take the pump apart and see what she looks like.
this just makes me double sure that im buying the larger shaft
Why? Like it is going to help you when your pump picks up something like mine did....
trust me I would rather be driving the car then tearing it apart for something to do... THIS is WHY I tore it arpart to begin with.... Was on the road course, downgeared in to 3rd, heard a "SNAP", lost oil pressure, pulled into the pits and shut it down.. (was just outside of the pits)
I tore the oil pump apart and all looks fine in there... besides... how would those big chunks get back into the pan if they grenaded inside the pump?
here is a better pic of the pieces that concern me...

the twisted pretzel of a shaft doesnt concern me, I need to know what thos things are.... The motor ran fine up to and even after the oil pump seized, so I have no clue what they are..
...expensive... if you put them in the gas tank they will find their way home.
so the pump looks fine inside?? no sign of what locked it up??
theres only so much those parts could be
start ripping into it and find out...
Good call, they can't unless the pump was busted...
Inspect the rockers, maybe those cap looking pieces are part pf the retainer that holds the roller pin...
Hey at this point it's as good a guess as any, and not hard to check...
thats what i was thinking something valve train related
wide peices valve springs?
round peices part of rockers?
That's what my oil pump shaft looked like in the first '88 Bird that I had...although I had no big debris in the pan...when I took the pump apart it looked fine...it's worth upgrading to an aftermarket oil pump shaft...how much more will it cost?...2...maybe 3 dollars more than a stock replacement. Under 20 bucks for just about any aftermarket drive. Otherwise you're just... :punchballs:
Good luck,
Don
ok guys, I just went and talked to a buddy of mine that has been playing with these things for years, he gave me an idea where to look:

(http://i205.photobucket.com/albums/bb170/1WLDBRD/DSC04402.jpg)
Only problem is, they are all there... which makes me think, someone over reved it at somepoint, hit valve float and wrecked the heads, so they upgraded to these ported ones and didnt think to check the pan for any more debris....
Looks like I may be safe to throw it back together...
Since you have another car. I would say be safe and tear it down just to be sure. You caught it before anything too damaging happened so on the safe side, spend the extra time and money as preventative or take the chances and go.
Down time now, or the chance of more money and more time later. I would just tear it all down now if i was the "just to be safe" kind of guy, but in reality I would take my chances
So they are lash caps !!! Isn't the one on left in second picture cracked???
Get some decent rockers on that engine!!! Ditch those caps...
As far as tearing it down, pull the intake... If there isn't anything in the lifter valley, I wouldn't worry about it...
I have stock a pump shaft in my 5.0... I'd rather break the shaft, than maybe screw up the Dist/Cam if something gets into the pump to lock it up... Any small debris can lock up the pump... Years ago it was common for bits of plastic timing gear or broken rubber valve stem seals to get into the pump and cause such problems... With such tight clearances, doesn't take much at all to totally lock up a oil pump...
^yeah I agree.. I will be swapping the Edelbrock Torker 302 intake for my brand new RPM Air Gap, so I will see if anything remains... as for tearing it down any further, I got laid off last week, so money is scarce right now....
your right too, the piece that jammed the pump, was tiny...
They look a lot like the plungers in a hydraulic lifter too. But I can't tell the diameter from the pic. My first thought WAS lash caps.
Those rockers are fine unless you are running tons of spring pressure and RPM. And then the roller trunnion is more important than a roller tip. But at that point you might as well buy full roller rockers.
Lash caps have their place where they are useful and needed.
Something had to cause the oil pump to stop. The distributor was still turning and twisting the shaft. You should check the bottom of the distributor too. Look at the drive gear and the shaft where the oilpump shaft was engaged.
already checked all that.. checked it the day it happened, everything else is fine.
some of your debris looks like the tops of lifters
but lash caps are the better idea.
