Rebuilding a cylinder head requires an insane amount of precision, and these tiny parts are a mechanic's worst nightmare! 🛠️ In this video, we are watching the installation of valve keepers (also known as collets) on a rusty engine head. The mechanic compresses the heavy valve spring and carefully places the two small, wedge-shaped keepers into the machined groove on the valve stem. Because the inside of the retainer is tapered, releasing the spring tension wedges the keepers tightly against the stem, locking the whole assembly together. If you accidentally drop one of these into an oil return hole during reassembly, it can require tearing the entire engine back apart to retrieve it! #mechanic #enginebuild #carrepair #valvesprings #enginehead #automotive #diyautorepair #carmaintenance #educational #cartok

Did you season the valve train with paprika?
Make sure to wear the clumsies gloves that you got! Sheesh! And what's up with that rusty valve spring? Sheesh again!
Oil! that engine hasn't seen oil for years
we afraid of magnets now? 😭
Brother, oil to that engine is like the faint smell you get that takes you back to your childhood but it's gone before you can remember what it was.
Looks like you will get to rebuild it again anyway
They made this look so much harder than it needed to be

Thats a nice spring your rust has.....
And that is why we build heads on a bench. No mess - no loses.
Legend has it that this engine is still for sale on marketplace to this day
it's good you equipped the Gloves of Minimum Dexterity
grease is your friend in that instance.
TAKE YOUR DAM GLOVES OFFFFL!!
Nice patina on that setup
Fun fact, I dropped one once in 2001... me and my boss spent an hour with magnets/bore scope... wasn't able to find it... he said replace it a d let's see what happens. Ran great, they came back in the fall for a new oil pan gasket, I did tge job, the keeper was in the pan. I still have it today
Its a miracle butter fingers over here didn't drop it all
😂 the more I watch the more questions I have
This is EXACTLY why that cylinder head comes off and goes directly to the machine shop.
I don't think I've ever assembled a head on the engine....
