Well, my little drip turned in to aunt flow after installing the header. I'm sure I must have moved a tube or two by my careful installation (IMG:style_emoticons/default/smash.gif) .
looks pretty easy to change these. Any gotchas ? And what sealant if any is the preferred. |

Look for lateral grooves, scores, scratches, or gouges in the PRT bores. If you have deep ugly gouges or grooves you may have a permanent leaker.
Jake Raby uses and recommends coating the push rod tube seals with a Locktite sealant that also acts like a lubricant when installing. I've used it on one engine with no leaks. Can't remember off the top of my head what the locktite product number is, sorry. |

I have found that removing and seating the tubes is best done by wrapping a hose clamp, screw down, then tighten it around the tube. Grab the screw with vice grips and use your hand or a hammer on the vice grips. Breaks loose the old tubes and seats the new.
