Re:Who can identify this plug??? G13BB engine

I hope you will be able to recognize this "plug"....Wich I found during the renovation of my
Jimny 2000, G13BB engine....and I can't find the place where it belongs in, or to....
Diameter is 10mm. and length 5,5mm....It looks like it never been exposed to the elements, since it looks new.
I haven’t taken any oil plug from the engineblock itself.
I tore down the head, and all of the mounted engine   hardware, like alternator, starter, etc, etc.

When installing these parts I seriously watched any corresponding hole, but never found anything..so it's becoming a nightmare for me, not replacing the plug...

So I really hope you have a clou.....Help!  

Thanx in advance!

Cheers!
 

This one?

Depending on its size it looks like plug 4,5 or 6
They all appear to be imperial thread, probably related to plumbing so water or oil way related. 

They vary in height from 12mm, 7.5mm and 5.5mm. Based on your measurement that makes it plug 5 which appears to be at the bottom of the engine block in the sump. 


 

Thanks for the reply!
These are bigger!, or smaller…and I haven’t taken any plug from the engine!

Thanks again!

Looks like Plug 5 to me, Probably shook loose and was resting in the sump

Hi Martin!

I haven’t taken the oil pump from the engine. The engine itself was not really “touched” Except for the cilinderhead; that was taken off.
And the rest like intake, exhaust, alternator, starter, are taken off.
No drain sump removed, Waterpump, Thermostate, Or sensors; those stayed on the block.

when I worked in a factory making electric stoves, we "lost" parts from time to time. You would not believe all the things that disappeared like clips, screws, tools, food Most parts we had counted and laid up so we wouldn't loose any but from time to time we lost a part or something and started to search all the stoves inside the production lines. most times we found the missing item but not all the time. A collegue of mine lost a brand new and expensive wrist watch and searched thru a hundred stoves but never found his watch.

Someone might just left this part somewhere? could even fallen off a tool?
