i think your main problem would be pumping the pressure into the crank case... you would have to upreage the seals so they don't blow out... this would be a job and a half as you would have to make them all yourself...
well lets just say that if you want to be discreat about it... make sure your suspenssion actually has some grease in it kinda puts a damper on things...
i will soon part with my first car (B310 sedan) after it was rear-ended. Not heaps of damage but enough to write it off. But $1000 and the wreaked car is a fair deal i think. Will all go through in a week or so
