Overfill? Easy way to remove some oil...

[Robin-535im]

Thought the board might find this useful, since there are posts from time to time on what to do if you put a little too much oil in the engine. I know this works on an M30 because I did it this weekend, it probably will work on all other engines too... someone will have to try it out and report back.

Step 1: Remove the air box and AFM, but leave the spark plug wires hooked up. Just unclip the AFM harness and let it sit off to the side.

Step 2: Remove the two nuts that hold the spark plug harness to the valve cover and ease the plug wires out of the way, still hooked up though.

Step 3: Remove the valve cover nuts and pull the valve cover off and set it aside.

Step 4: Start the engine. It may idle rough since it will be in open loop mode without the AFM signal.

Step 5: Let the car run until the oil pumps up into the galleys, about 5-10 seconds depending on the weight of oil you use.

Step 6: When you feel enough oil has been sprayed all over your entire garage, engine compartment, and recently-washed front fenders (hood liner too), shut off the engine.

Step 7: Reassembly is the reverse of removal. Be sure not to over tighten the valve cover nuts. You can get away with reusing the VC gasket if it's fairly new.

Maybe this will help someone out there as much as it helped me. And yes, I came up with this procedure all by myself. In fact, I was really just trying to track down an extra-noisy rocker arm, and just kind of "discovered" this cool trick. Had to share it with the board of course.

Does this procedure work with synthetic oil?

Genius! You must copyright the technique immediately!

That's all too much like work. stick a hose in your dipstick tube and use a vacum pump and suck it out.

Did you really go through all that! What a mess it must have been.

I was thinking I could drop the tranny to get to the rear main seal, then pop the seal and let it drain from there, but I didn't have anywhere to put the tranny to keep it out of the way.

Good technique! However, for the next overfill, you can save on the wrenching: simply remove the oil fill cap and do a few loops at the local skate board track. A 360 is worth about 125 mls ....
