i found this in my oil pan when i took my block apart... bad pic from my phone but what do you guys think this is??? and that a 10mm nut to compare size.... the banged up piece of metal had some numbers on it but it was hard to see what they were... it was like.... " sts " with more letters i cant read...

 

could be the nut that holds the oil pickup tube.

 

no the nut is just there for a seize comparison thing.... its the big chuck of metal..... wtf?!?!?

 

Wtf? terrible picture. Looks like aluminum tho. A piece of valvecover maybe????

 

lol wow.
were there any welds in the pan? (cover turbo lines)
used some metal and welded over the holes and it finally fell off?

 

Could it be a mangled bearing and a rod nut?

 

Highly unlikely due to size comparison...How was the motor running before you took the oil pan off?

 

i vote thrust washer!! we just pulled some very similar mangled metal out of a friends motor that lost a thrust washer.

 

Like stated how was the motor running before you pulled the pan off? Did you have a magnetic plug or was it just sitting there?

 

The motor ran good before i pulled the head off... All the rod nuts are there still(arp)

 

no i didnt have a magnetic drain bolt... But it one piece was in the oil pan, and the large chunk of metal was sitting on the windage tray

 

Did you put the motor together or did you buy it like that? Im guessing it was turbo'd? Im thinking Thrush washer if you dont see any nuts missing...Unless somthing got left in the motor when being built.

 

I think robocop shot a load in your oil...... dam... your engine has been ropo raped... lol

 

If it had a very heavy pressure plate and/or the driver rode the clutch endlessly, it very well could be a thrust washer. Once one side wears away, the other side has play to pop out, get juggled by a crank, rod, and piston moving upwards of 22 meters per second.

 

i didnt put the motor together myself.... a local shop did. ima take it to the shop when i get a chance.... the motor was only on about 12,xxx miles fresh...im dumbfounded lol

 

Looks like a thrust washer. Looks like what I found in my oil pan, and it turned out to be a thrust washer.

 

good lookin guys. i looked at some brand new thrush washers that i had laying around in my garage for my jdm gsr and theres a part number on it that says STD and it matches that piece *** piece of mangled metal i found in the oil pan. thumbs up to you guys.

now 1 more ?
the thrust washer that i have for my jdm gsr will work right?
i have a b16a 84.5mm stock crank 8.5:1 comp

 

i was right!! dout me and get trust washered!!!!!! i can identiy bad probs weeks before they happen thats why im not a caps lock away from be9ing coool

 

dam u hit jackpot!

 

It probably will, but at this point, the thrust bearing surface of the crank is probably TOAST, and maybe the block's thrust surfaces as well. You also might have lots of wear on the rods' big ends, since the crank was allowed to move back and forth.

The real issue is findin out why it ate the bearing in the 1st place. If you don't it will probably keep doing so. As I mentioned before, its usually because of a VERY heavy pressure plate and slipping/riding the clutch a lot. Ask a VERy experienced race driver to watch how you use your clutch, because 99% of the people that ride their clutch don't think they do - they do it because they learned wrong.

 

ouch, a crank walk'd honda engine

 

I still have my ACL thrust and main bearings from my B16A build. If you need them let me know and throw an offer.

I wonder how much play your crank has after installing all of the thrust washers?

 

wow I though that when you dropped out the thrust bearing your bottom was pretty much toast and would self destruct itself.

 

so would you guys suggest me just using a new crank?

 

I would pull everything apart and inspect. I'll look for obvious signs like discoloration and deformations.
