I have a 06 CRD and tried to change the oil for the first time. This is the oil drain plug under my CRD. I have never seen the flower petal shaped head before... Please help. What exactly is this and what size? Thanks for the help.

This is the O.E. drain plug. The hex key drive shape has been severely worn from use and has taken on the flower petal shape.

Your best bet is to replace this plug with a Fumoto Oil Valve. Install it once, and never have to remove it again. Here is the link...

Well, i would love to take it off, but nothing fits. What size is it?

FYI, I tried 8mm allen wrench and it doesn't fit...

If your going to replace it anyway, you could probably get a pair of vice grips on that.

I had one I had to weld a bolt too and then I used a socket. I think previous owner stripped it so bad than never changed the oil and caused the turbo to fail at 90k. :banghead:

I had one similar to that. First I sprayed with PB blaster then tapped it lightly several times, , then I hammered a cut off chisel just slightly larger than a section of the hole gently into the original hole. Next, I clamped vise grips on the thin outer flange . I had my son put open end wrench on the chisel shank snugged up to the oil plug so as to minimize torsion and then I put firm pressure to the vise grips and he started putting progressively more pressure on the chisel shank and it came out.

Since the coefficient of expansion of aluminum (the oil pan) is greater than that of steel (the plug) I also got the engine warmed up just prior to loosening. Once broken loose it came out freely. I did same thing with another CRD that with first change the allen wrench took a lot of pressure and I thought it was about to strip.

I recommend having a fumoto valve ready to replace any standard oil plug before refilling with oil. They are also available on amazon with immediate shipping.

You might also put in some 5w-30 non synthetic cheap oil and seafoam or other engine cleaner along with a cheap oil filter for about $20 and run a little maybe 50 miles or so and then drain that and put in the good stuff. If you have to wait on fumoto just put some washers under original and anti seize on threads and don't over tighten . Then you should be able to remove with vise grips easier when it comes in or get hexhead bolt to replace it.

The aluminum threads in pan are easy to strip be careful but there are threads here on retapping etc.

Hope you already got it out!!

In addition to the ideas here, the suggestion I have is an Easy-Out reverse drill extractor set.

The largest size of this set doesn't fit in an impact driver (for reasons that make no sense) but you could probably use a socket adapter and appropriate socket size on the tool if that is the one that matches. Otherwise the smaller ones fit right in a regular impact screwgun
and should lock right in and spin that sucker out.

If it doesn't work, you still have the other options of vice grips and reverse drill bits from Harbor Fart... And then definitely replace that with a Fumoto.

Might be able to use a dremel or cut off wheel to put a flat slot into it and use a big ole screw drew driver.

If you haven't removed it yet, use an easy-out.

Get a torx or Allen wrench that would be just a tad bigger than the hole and hammer it in the plug. Take out the plug, recover your tool, throw the plug away and install a fumoto valve.
