6mm x29mm Bolt came out of the drain plug
I was changing oil on my mercedes e300 diesel 1996 when a 6mmx29mm bolt came out of the drain plug hole.Where did this bolt come from?

Yikes.
I took a look through the EPC net schematics....and it does not say the size of the bolts, but, the oil pump assembly has the most small bolts that I can see....hopefully some others here have a better idea what it is. Has the engine ever been opened up for service in any way? That would narrow down if it might have been dropped in by accident, or if it came off something important inside the motor....

you sure it wasn't in the oil collecting pan when you drained oil. did you actually see it come out. In any case, not worth being worried about something you can't do anything about. I assume car is running find without it.

Can EPC shed some light on this? I know Citroen parts manuals and earlier Benz parts catalogs included the dimensions of every fastener in their descriptions, do you have this kind of catalog for your E-Class? If so, it might help, if not, maybe the dealer parts guy can tell you.

EPC doesn't break it down to the size of the bolt....but the FSM for the 606 probably does....

does your engine have the front three head bolts normally marked as 'a' in the head tightening diagrams .i assume this is similar to the size you have recovered. easy to check

6X29 is a pretty skinny bolt, a little bit longish.
Should be easy when understanding design of engine. It's not coming past pistons. Are there sheet metal baffles anywhere? Could it have migrated down timing chain cavity? It's probably something to do with oil pump. I rather think it's not important whether EPC lists sizes, as there are very few applications for bolts this small.

I found this website that has diagrams of the oil pump assembly and the bolt sizes. Actually the bolt is 6x30 after I remeasured it . It's looking like one of the oil pump combination bolts. It has a washer made on it. Does anybody know how much trouble it is to remove the oil pan? Thanks for the replies. |

Not a diesel guy, but I've seen bolts that size used for securing valve train parts on gas engines in other makes. In fact, I dropped one down an oil return hole in the head once - thank god for extendable magenetic pick-ups!

I removed the oil level switch and the oil cooler from the sides of the oil pan and replaced the bolt. Thank for the reply
