I swore by the old school way to seat injector cups until a guy in the shop showed me something better
For years I'd freeze the new cup and heat the head with a torch, then tap it in with a brass drift. It worked, but I'd still get the occasional leak on a 6.0 Powerstroke and have to redo the whole job. This old timer, Frank, who works the night shift, saw me fighting one and said 'try this, kid.' He took a piece of 3/4 inch copper pipe, cut it to the exact length of the cup, and used it as a driver with a regular slide hammer. The copper is soft enough not to damage the cup but transfers the impact perfectly. I tried it on my next job, a 2005 F-250 that came in last Tuesday, and it seated flush on the first solid hit. No walking, no cocking, just a clean seat. I've done three sets since and haven't had a single comeback. Anyone else use a trick like this for stubborn press fits?

That copper pipe trick is brilliant (and cheap). I bet a piece of nylon rod would work the same way for softer aluminum heads.

Oh man, that reminds me of the time I used a wooden dowel to fix a dent in my old fridge door, worked like a charm.

Boy howdy, that delrin rod trick is a good one. I've used nylon before on aluminum and it works great because it won't scratch the surface up. You gotta love finding a simple fix that beats paying for some overpriced specialty tool. Got any other weird dent removal tricks that actually work?

Remember my dad using a chunk of delrin rod to tap out a dent in his old motorcycle's gas tank. He heated it with a heat gun first to make it soft, just pressed and wiggled it until the metal popped back. Stuff like that always works better than the "right" tool sometimes.
