I want to replace my push rod tube seals without removing the heads. Do I twist and pull the tubes with pliers? Also, my engine is out of the car and I'm reinstalling the injection, re-sealing and doing a engine clean up...My compression was good at 130 psi with no smoking. I don't really want to pull the heads and cylinders but do you see any real advantage to doing this, (ie. honing the cylinders and removing carbon).
Thanks for your response |

I don't use v-grips or pliers. I find a socket the same diameter as the PR tube and use it to push the tube into the head and case.
And to take them out, if they are leaking, they are loose and lubed up so I can usally pull them out by hand. |

I use the handle end of a screwdriver. It fits the end of the tube nicely! Big problem: No room for it when the engine is installed. So you have to push them in with your fingers or with vise-grips. I've done both, both work. Vise-grips are nice in that you can set the maximum amount that they will squeeze the tube, so it is not as likely that you'll crush them. If you pull the tubes out by hand, wear sturdy work gloves! I took a good chunk of skin off my hand one day when I caught my hand on the edge of the cylinder head when the tube popped out. --DD |
