Hey fellas: I'm in the middle of swapping in a 16cm housing, have the turbo and housing out on the bench, and it's siezed where the two pieces meet, and I mean tight... .combo of 13 years of heat and good old Ontario rust and salt, she wont come free. Any Ideas or tricks ? I have it soaking in penetrating oil overnite. Should I just take a cutting wheel and split the old housing ? :--)
