Recommended Posts

Posted

ok, ive had my z for over a year, took it off the road and bought a 2000 GTP. now that winter is coming around, i dont wanna run my GTP Sooo i have to fix this Oil leaking o-ring that has leaked since day one when i bought the car. I've been putting this repair on hold due to the amount of work involved...i've finally grown enough cahoons to dig in. So, plenum is off, lower intake is off and fuel rail is off.....leaving one sad lookin dummy shaft with oil all around.... i tried following Jar's procedure listed on the Lumina Z34 message board. Heres what i did. I started out by taking my dremel and filing the cap down. I filed it down about a 1/4" on one side and rounded that side off. I filed just over 1/4" off on the bottom of the plank where the lower intake bolts to the head covering the shaft...what am i doing wrong here? i got the shaft to slide up a lil over an inch, but its still in there....i dont wanna take anymore off the head because i dont wanna affect the clamping on the head for the lower intake.....what do i do? PLEASE SOMEONE HELP ME OUT OF THIS MISERY!!!!

Do you have the dist. drive lifted up high enough to see the old o-ring? You might just have to sneak the old one out and the new one in there with the shaft still in there.

clean it real well and do what every other lazy ass with a 3.4 does...high temp silicone sealant. or...be smart...do it right...and pull the head. its not that big of a deal.

a while ago someone posted how they fixed it sayin' you can trim the head a little bit right there, and trim the oil pump drive a little bit right there, and squeeze it out ...

 

might be worth it to try the search function, I know it's been posted before with pictures ...

nope. 93GTP or whatever the name is showed pics of pulling the heads off.

Pull it up and clean the area with break clean. After it dries(break clean dries really fast), get an o-ring off a mag light. streach it over the cap and get it between the block and the shaft. Then hi-temp silocone the hell out of the top. clamp it back down and let it dry overnight.

 

I did it this way, and havn't had a leek since.
