BAD DOG Posted March 12, 2016 Share Posted March 12, 2016 Found these two funny looking l little critters on the oil drain plug in my engine . Any ideas as to what or where inside they may have came from. They look like pieces from rivets? Look like aluminum but stick to a magnet. Everything seems to be working fine but the curiosity is killing me. Quote Link to comment https://www.bigmacktrucks.com/topic/44314-mystery-metal/ Share on other sites More sharing options...
BAD DOG Posted March 12, 2016 Author Share Posted March 12, 2016 I'm wondering if they came came in the oil or were in the Car Quest oil filers. May have been some shrapnel left behind from a bunch of damage caused in an accident a few years back.

BAD DOG Posted March 12, 2016 Author Share Posted March 12, 2016 Yeah they don't even look like anything I've ever seen inside the engine. Look like ends off of rivets but I don't remember anything with rivets inside when we had it torn down. That why I think they could be from a foreign source.

carlotpilot Posted March 15, 2016 Share Posted March 15, 2016 those are tips off of piston cooler nozzles Quote Link to comment https://www.bigmacktrucks.com/topic/44314-mystery-metal/#findComment-327499 Share on other sites More sharing options...
BAD DOG Posted March 15, 2016 Author Share Posted March 15, 2016 Haven't figured it out yet. They re solid on the ends so I don't think they're from the piston cooling nozzles. They sure look like the mushroomed end off of some kid me of rivet. That's what's puzzling me. They don't look like a Ke anything from the inside of the engine.

carlotpilot Posted March 15, 2016 Share Posted March 15, 2016 they could be from some other source but they sure look like the tips i spoke of . as well as appearing hollow in the pics you say they are solid? not possibly battered shut from being batted around in the engine? i don`t have a cooler handy to compare but if that is what they are you would have noticed a slight drop in oil pressure cc Quote Link to comment https://www.bigmacktrucks.com/topic/44314-mystery-metal/#findComment-327573 Share on other sites More sharing options...
BAD DOG Posted March 15, 2016 Author Share Posted March 15, 2016 She still runs 35 to 40 at an idle and 80 when you run it just like it always has so oil pressure seems to be ok. I've had issues with cooling nozzles in other engines before and oil pressure did drop. The pieces identicle They look like a cross between buck rivet and a grease sert. But are solid on the one end.

br549 Posted March 18, 2016 Share Posted March 18, 2016 What kind of engine do you have? At one time years ago and I cant remember when people were putting pop rivets in the rocker arm at the end of the slipper oil hole to keep oil from coming out, I think it was to cut down on oil around valve guides before valve guide seals, pull your valve cover and check the oil holes and see if any pop rivets are in your's, I seen several engines back in the day.

br549 Posted March 19, 2016 Share Posted March 19, 2016 It was not on a V-8 mack, I think it might have been on the first E6 4 valve engines, I don't think it came from mack that way but people were doing it on their own, I remember seeing 3 or 4 trucks done that way.
