Internal Slave Cylinder Leak

[stevn94]

Hey Guys, Iam a newbie, Names Steve.. 1994 Cavalier Z24 5 spd 3400 swap
Long story Short i Replaced the Internal Slave cylinder 3 times Now!!!!! Dorman brand, Warrenty. the last time i replaced the master Cylinder,,, Everytime it leaks within 50 kms of driving. Now I had the flywheel resufaced when i did the Engine swap thats when this all started... Should i have added a Shim between the crankshaft and flywheel after resufacing??? Also the 3400 came with a dounut washer installed infront of the flexplate for the auto trans ,Should i install this in front of the manual flywheel or lose it?? Somethings Has to be causing this????? I can't see getting three bad parts in a row???? This time the part store gave me my money back on told me to take a hike?? So this time i ordered a wagner brand Slave!!!

I too had a brand new one start leaking (I forget the brand). I replaced it with a GM one with over 100k on it and all seems well so far.

As for shims, I use a small shim (.020 maybe?) and my flywheel has been ground at least twice. Shims are not very important for internal slave cars. You would need to have a crap load of meat shaved off your flywheel to allow the slave to over extend and leak.

I understand that you are probably really pissed, I was when I had to pull my tranny for a part that I bought new, just so I wouldn't have to replace it.

Dorman is not the greatest.

Hey, So Got it all together Last night,,Sure enough Just after Bleeding, It started Leaking and lost all pedel pressure .Figures Didnt even get to drive it this time.. But anyways, I am planning to swap to a HM-282 (Getrag/Muncie) Used with the external slave Setup, Do i have to use the Flywheel off the car i Get the 282 From or can i use the one i have now off my NVG T550 from the 94. I Know it's a Different Clutch, Already ordered it. Just not to sure about the flywheel... Thanks
