    Mystery milkshake after pan gasket change

    Well, I pulled the motor and she's dirrrty. Greasy carbon build up throughout the intake manifold into the heads and overall just covered in oil residue. Looks like the oil pressure switch was leaking for awhile. I had to change valve. Cover gaskets when I got the rig, cause the PO had let it...

    Mystery milkshake after pan gasket change

    No worries! These threads can get pretty long. I am hoping to have the engine pulled by midday tomorrow. And then we'll tear down and we'll see what we see.! I appreciate everyone's help and suggestions!

    Mystery milkshake after pan gasket change

    Looks like I found the problem.Driver side water pump connection was leaking.You can see in the picture how it's cleaned the front of the timing chain cover. I must not have got the pan gasket on correctly And coolant leaked into whatever gap there might be. Still seems odd.There was no sign...

    Mystery milkshake after pan gasket change

    It crossed my mind, but it is too coincidental to The timing of the repair. The engine still runs absolutely perfect.No misfires no check engine lights, idles completely smooth. As I pull it apart, I'll be checking in take manifold gasket. And I might be left with no choice but to change the...
