M104.98x Stuck Coolant Drain Plug
Hello,
I made some progress with my M104.98x top end rebuild.
Today I took care of all the components from the bottom of the car. All went fine up to the point where I tried to drain the coolant from the block. Using a 19mm socket and a 13” long 3/8 ratchet I tried to loosen it but it is froozen, I sprayed some kroil and it started to move (very very hard) I worked it out 1/2 turn when it got completely froozen again, antifreeze drops came out.. I tightened agin as I didn’t want to risk it. I’ve done a few M104s overhauls but I never encountered a drain plug that stuck..
Did anyone experience something similar?
