how do i fix this problem and how much would it cost? its a 1990 t2

You need a rebuild.

In the nabourhood of 2-4k.

4k = got owned,

i dont know any shops around here that charge that much.

I have charged over 4 k for alot of motors.

How much do you think you would spend to have a fully ported, new housings, all nes sensors, wax pelets, gaskets, dowled, 3mm seals, ect ect.
hey dont come cheap. You can get a factory rebuild for dirt cheap.

ah i was talking about a factory rebuild because all he wants to do is fix his apex seal.

your rebuild is nuts, you are actually building the motor.

i had no idea you pinned, used 3m seals etc
