when you changed the seals did you hone out the cylinder? that could be one of your problems and you should change your oil it might have some crap floating in it and its going into the cylinders and killing your seals

dont just replace the seals..use good ones...get some poly pak seals for those cylinders unless they are scared up on the casing wall..but i have poly paks in my car and one set is 2 years old and the rears are over a year old and havent touched them since...i been using poly pak seals since 2005

use non detergent. the detergent dries out the o rings and causes them to deteriorate

i bought some locally and paid 10.00 a ring, and they are a bitch to put on, but worth it ;) make sure you put the skirt side of the seal facing inboard to each other...

They only work one direction. You have to put them like this \| |/ so that the pressure from the pump pushes the seal tighter against the wall of the cylinder. If you put them like this /| |\ Then the oil will just go past the seal.

I was doing my poly pak installs like ur bottom pic with the lower seal on both ends. Never had a issue with them like that. But I now do them like ur pic and I still get the same results. They work perfect.


Also I have a set of poly paks on my front cylinders and they are about 2 yrs old if not older and i hop on them. No leaks.

If u can't get poly paks then try to find quad seals. They are also a good O ring. I even use quad seals as pressure seals between the block & pumphead

Just make sure when u go to reinstall the shaft into the casing lube up the O rings and the casing so u don't turn the o rings over or tear them

This how I would see it working. I would assume that using two facing different directions means only 1 is working.

you shouldnt be using 2 'poly paks' in the first place, in my opinion. Only the bottom one.
then u have no back up O ring if the other fails
