Changed pushrod tube seals to fix a slight leak. In the process, I must have bent the rod retainer, Part # 021109339, slightly which caused a bigger leak. While trying to bend that hoaky springlike contraption, it broke. Has anyone designed a better one that puts more pressure on the tubes and seals? The original design seems not very effective. So far I have not been able to find a replacement.

The wire retainer just prevents the tubes from sliding away from the block and out of the bore. In addition to dirt, a few other things can affect sealing...like the seal getting hung up on a sharp edge and being damaged on installation (easy to do)...or the pushrod tube being out of round. If all is as it should be, the o-rings should seal well without any additional help. I'd use new tubes and Viton seals. Clean the bores till they're spotless, spread a little motor oil around the seals on assembly and make sure all are fully seated in the block. There's usually a satisfying little bump / pop when they hit home. Good luck! |
