Some brake jobs can turn into headaches when small air bubbles get trapped within the caliper itself. To resolve the problem, you could pump the brakes over and over, or you could try this handy suggestion to free the air bubble and move on with the brake bleed process.

Recently, I was talking with Shop Press head honcho (Chief Bottle Washer—Ed.) Lemmy about something I wasn’t familiar with: dry sump oil systems. If you’re a newer tech who hasn’t worked on any high-end sports cars, you also might not be familiar with these systems....

Removing valves from a cylinder head should be done carefully if you have a notion to reuse the valves, springs, collars, and keepers. A spring compressor is the right tool for the job.
That said, in my salvage yard days, I learned a trick I still use today if I’m stripping a head for scrap. It’s the fastest method in the world, hands down. I’m not gonna say I’ve never pulled this trick on a customer car, but I will say I don’t use it often nowadays.
Pull the head and the cam(s) if it’s an overhead cam engine. Set the head on a non-marring surface with the valve stems pointed up.
Select a socket with an OD that’s a little smaller than the OD of one of the valve keepers.
Flip the socket’s open end onto the keeper and whack the end with a deadblow hammer.
Lift the socket up carefully, collect the keepers, collar, and spring. Lift the head and fish the valve out of the combustion chamber. (Keep ‘em together and labeled if you’re gonna put these parts back into the head or you’re lapping valves.)
If you’re quick and you’re not worried about retaining parts, you can strip down a four-valve four-cylinder head in under a minute. Watch your hands and peepers!
