Lifters , the bit that follows the cam profile to move the push rod to lift the rocker up and down to open and close the valve
Buckets thats the bit over the top of the valve that holds in the springs and valve
Tappets or rockers are the bits that lift up and down via the pushrod as the lifter moves up and down via the cam profile
Do a google surely there would be a pic or two of a conbustion 4 stroke engine
Overhead cam engines well there different again .....
Yep, and the older engines also have "collets" to retain the valve spring, the modern engine has changed a fair bit, but the basic idea is unchanged.
I'm hard to trick with the old pushrod engines, but I'm still learning about the modern OHC motors, this forum and others has been a great source of information.
YO, the internet..
Now the rotary engine is another story!!

Reading this brings back memories. Was cleaning out my shed a couple of months ago and found a bottle of valve lap grinding past (still wet), the dowel with the rubber suction cup, home made valve spring compressor. Even the old MK1 Cortina service manual, well used and lots of finger grease. Still have the timing lights and other diagnostic equipment, just nothing to use them on. Those days are long gone.
We've come a long way, now I open the Patrol bonnet and go WOW what's that for.
Cheers
Ha ha, I open the bonnet, have a quick look and shut it again, if it aint got a dizzy and plugs, I don't go there lol
Cheers, the ferret.
Haha. You open the bonnet and go "OUCH" when it lands on your finger lol.Originally Posted by the ferret
I learnt the hard way what little I know by building (then rebuilding) and old Holden 202. A good engine to learn on as you can see how everything works and it's quite simple. Did all the stupid stuff like dizzy 180 out lol
Tap, crackle, pop
Hello from Under Down Under!
I was lucky started on bmw's audi's and porsches etc at a young age they were always 20 years ahead of the game and things haven't advanced that much since.
But diesels are a whole new world and quite simple in comparison gotta luv em.
