I saw this term in the book, Zen and the Art of Motorcycle Maintenance, and looked into it because it was an engine part I had never heard of. It seems this is an older term for the hydraulic lifters in an engine. These are the parts that ride on the camshaft and push the intake and exhaust valves open.
yes you do have to set the tappets
Is it a big problem to have noisy tappets in your engine?
adjust tappets on saxo 1.1 and gaps
no unless you change the size of the rods
Yes, to access the tappets(lifters) you have to remove the cylinder head.
There are two tappets per cylinder in that Dodge 4.7 engine, so the answer is 16.
Cars with 4 stroke internal combustion engines usually have tappets. These are metal caps on the valve stems that are pushed by the camshaft to open the valves. Two stroke, rotary and turbine engines do not have tappets. Electrical cars do not have tappets.
