Guest rockabillybassman Posted September 5, 2007 Report Posted September 5, 2007 Does anyone know if it's possible to replace valve seats yourself? I'm just curious. Mebbe if they were kept in the deep-freeze for a while, and the area around the seat was warmed up with a torch? Quote
martybose Posted September 5, 2007 Report Posted September 5, 2007 Maybe if you used liquid nitrogen and a big torch. These aren't like wheel bearings where you need them to be snug; you really don't want these to be able to get loose. Marty Quote
grey beard Posted September 6, 2007 Report Posted September 6, 2007 Years ago, when I was a kid and just learning, I worked with a master mechanic who replaced some seats in a flathead ford. He drove them into place with a brass drift, after a good cleanup of the area, and then staked them with a cape chisel. Memory says it worked fine, but I have never seen anyone do this since then. I'm sure machinists can make an interfearance fit of .001-inch, and just press them into place. Come to think of it, I've never seen a MoPar flattie that needed valve seats. They're preetty bullet proof, from what I've seen. I've replaced valves that were burned and guides that were shot, but never had to do a valve seat on one of these. I know they are hardened - better than many other brands of engines on the market. Replaced the front exhaust valve guide on my pickup. Just drove the old done down and broke it off with a hammer - like our tech tips says to do, and it came out quite easily. New one drove right in and I reamed it to size - knurled the rest and they fit very nicely. JMHO Quote
