well ernie...
the part that goes into the case is not the problem..actually the push rod tube should go in..about 1/8 to 1/4 inch..past the seal and the two washers... the way it is made up ... is...
the first washer.. naturly its cont engine part... and it goes against the case recess... then you have this big squishie rubber donut kinda thing.. then another washer and then a spring which pushes aganst the push rod tube and the top washer...
The way it works.... is that the push rod tube bead presses against the spring.. which then presses against the first washer...which then causes the rubber donut to expand which pushes against the first washer... now while the donut expands.. it seals against the inside recess of the case lip... sealing the oil from coming out...
the other end of the push rod tube then goes against the cyc head and a rubber O ring and seals the head oil which comes from the rocker arms and goes back down the push rod tube... inside and dumps into the crankcase...
So when he says the hole is bigger ... does he mean the washer or the case itself...????
1200 hrs on a turbo is getting on in time.. about 1400 is all they will go... GMAs
