After browsing the stovebolt pages for the past three months and I decided to tackle my first project, changing the rear main seal. After dropping the oil pan I was looking in the bottom to see if any sludge had built up and I found this metal clip, see pic? Can anyone help me identify the part? http://i1352.photobucket.com/albums.../IMG_20130316_114215_965_zps50cd100f.jpg Thanks in advance for any help RobZ | | | | | Joined: Dec 2003 Posts: 2,733 Shop Shark | | Shop Shark Joined: Dec 2003 Posts: 2,733 | Can't do anything with that URL.

(Don't know the Chinese word for the French word sabotage). Maybe previous mechanic was cleaning that piece on his bench grinder with a wire wheel on it and it flew off like half of everything I try to clean up on one of those "parts slingers" and ended up inside the disassembled engine. I'll bet he is still wondering where it went.

Can't imagine how it could have gotten inside the oil pan! | | | | | Joined: Mar 2011 Posts: 457 Shop Shark | | Shop Shark Joined: Mar 2011 Posts: 457 | That "M" indicates it's Motormite part, probably part of a replacement drain plug used if the threads are stripped out of the pan. Works like a toggle bolt.

Some did that when they would attempt to put a PCV system on their truck. | | | | | Joined: Nov 2006 Posts: 2,544 Shop Shark | | Shop Shark Joined: Nov 2006 Posts: 2,544 | Sure looks like the toggle end of a toggle bolt to me.... | | | | | Joined: Sep 2012 Posts: 13 New Guy | | New Guy Joined: Sep 2012 Posts: 13 | Thanks to everyone, my guess was a toggle bolt also. My only problem where it came from? The oil plug was not stripped and the draft tube is still installed. Well I guess I will continue on with the rear main seal and not worry about it for now.
Thanks again

Interesting find in your oil pan. It was great meeting you this weekend. Drop me a PM.

So many rebuilders throw all the parts they have to every engine in one pile. This is perfectly fine but mabe they guy filled the pan with parts and did not get them all for some reason. If you are throwing all your parts in one pile like that always make sure you have everything. If I were you I would pull the valve cover and side cover just in case there are more surprises. | | | | | Joined: Jun 2012 Posts: 1,747 'Bolter | | 'Bolter Joined: Jun 2012 Posts: 1,747 | My money is that it got caught under the sheet metal baffle and was just over looked. Never got in the way of any thing moving so lucky you. Put a nail through it and hang it on the wall to remind you to look at every thing before you install it. You can learn from the other guy's mistake and not have to pay the admission price.
