1) Question about this matter, whats the best way to tap the pan? better yet, whats the best way to tap for oil drain?

2). regarding the oil pan. Is it a simple unbolt and drop? (with the needed cutting of the gasket)

3). where is the best place to tap? which of the corners, how high? (dont really know where the oil level is at )

4). where is the better place to tap for oil? Sandwhich plate or Oil Sensor?
or suggestions

Thanks!

 

guess not a lot of GS400 owners dont really do this :/

 

bump. I am in need of this info as well.
I know there are members that have done this before.

 

Yes. please someone share some info. mainly where is the most optimal place to tap at... for the drain hose.

 

Well, it's like any other pans. Get a tap and dye set and tap it out. It's most recommend that you do not use a too big or a drain plug or else you might ending up cracking the the pan. In cases like this, it's a 50/50 chance, either you succeed without dripping oil or you just fail, in worse case buy a used oil pan.
