190E oil sump drain plug

[mrbumble]

Does any of you fellow merc fans know how I can undo a badly rounded off sump drain plug?
Also is it common for the 190 on a cold start to hear the odd valve lifter have a few noisey taps then disappear?
Hence the urgent oil change :!:
Thanks in advance!!

You could try a couple of things that have worked for me.
File some flat sides on the sump plug, or if you have the space drill a hole through the side of the plug, put a metal dowel through the hole and turn, or cut a slot in the plug head and use a large screwdriver to undo it.
Good luck!

No way on this earth will you loosen a sump plug on a merc with a screwdriver. Best bet to loosen it is a turbo socket, these are used for undoing rounded nuts & bolts. Or use a pair of, vice grips or hammer a smaller socket on to it taking care not to damage the sump or tack weld a socket onto it Hope this helps

nice one guys, as soon as the sun shows its face im ready for oil action..
what about the lifter subject any ideas?

The lifter may be dirty... but they are cheap and easy to replace.

I agree with 190 about spot welding an old socket or spanner onto the rounded off nut. A bit extreme maybe but it will work and it gives you the excuse to spend £50 on a cheap arc welder. (just remember to disconnect the car battery first)

Thanks for the ideas chaps, but after 3 hours and a couple of scraped knuckles i managed to file it into shape so with a ring spanner and old faithfull mr hammer the stubbon git moved.
Spike can you really get a arc welder for that price and where :?:

Arc welders have went down in price. Most people now use migs.At £50 you wont get anything very exciting.
