Hi Jacob.
I just remembered of an 4 cylinder 22RE engine on a 4Runner that I once owned that required the valves to be adjusted hot. You had to idle it up to operating temp, open the valve cover, adjust two cylinders, close the cover, idle it to temp again, open again, adjust the two remaining...
That said, you got me curious if the TB was something like that and I found on the manual that the clearance you used cold is actually meant to be for hot scenario. In a cold scenario they should be a bit tighter. The manual doesn't mention that thing of doing two, heating again, doing some more two, etc, but it kinds of make sense to me. I am by no means an expert on the subject, so please, take your own conclusions. I just meant to add to the discussion.
Cheers!

Thanks for this - the info I have sort of confused me as it stated the ame for hot and cold setting. Your info makes a lot more sense.
Will do that and see how it goes.
Unfortunately it looks like the whole rebuild was lost time - the first trials point to coolant loss again.
I was hoping to avoid a new head ....
At least got some training now
But who knows .... maybe maybe I am wrong and the engine behaves better with proper tappets settings.
thanks again - I will let you know:
J.

.........
BillyJ Legend has got me thinking that Ambient Temperature/Hot Hauling Usage regional conditions might alter settings when needed versus old school set in concrete Nissan manual bible specifications Australia wide?
All I nuffy know is that whilst flogging our old TD42 towing up in our Northern Territory last year full tilt sun up to down it would clack away at idle each night whilst easing down for a snooze.
Back home in Victoria with less than 4hrs colder north to a border they’re back as tight as free needed I believe now?
