So...everyone here knows that I am NOT very mechanical. Some one asked me a question yesterday about my MGB and I have no answer. The car was built August 1970 and S/N is GHN5UB220017 G which makes it a 1971 model. Question is: does the engine have hydraulic or mechanical lifters? I don't even know the difference or what a lifter looks like :frown:. Any help here? Thanks

Gary

Lifters are part of what connects the camshaft to the rocker assembly - in other words, it is part of what makes the intake and exhaust valves open and close at the right time.
 
Thanks guys. I appreciate it.
 
And if original your lifters look like the ones in the drawing and not the ones with the pic. 1972 was the first year for the short lighter lifters and longer push rods. Bob
 
The reason you need to adjust your valves every 6,000 miles is that you don't have hydraulic lifters. You are adjusting your valves, right?
 
Uhhh...not yet. :frown: I don't know how but a friend who does is coming over this week to help. Thanks guys...I need all of the help I can get.
 
If ya got someone who knows how to set 'em, NO PROB!!!
 
Thanks Mark
 
My personal goal is to be able to adjust the valves as fast as John Twist does it in that video. On a good day I think I'm up to about three times as long.
 
I suspect I'll at least double you Davester !! :smile:
