BTW, you did sit in the shop all night and wait until morning when the engine was stone cold to adjust the valves... right?

Cheers!
Are tappets set hot or cold? That depends on engine
These are shit engines and badly made tappets as there's a weird angle between the adjuster and valve
Won't make much if any difference as you can't truely make up for poor design
Hot or cold both will be better then twat mechanics here
If hot do a slightly smaller gap - the old design won't make any real difference

Just use a good reliable method not the twat method
