Nice looking car. The dashpot can be checked by seeing if it's airtight: open the throttle and pinch the hose above the VTV. If the dashpot holds the VTV is bad. As you said the 51 can be checked by measuring the TPS per the TSRM. To check the wiring jumper the pins on the harness connector...

^ Cool story bro...

It's 1.25, at least an old shifter I still have is. Thread gauges are wonderful things...

No. That's why it's called the elastic region. And you'd need a lot more heat than that. My car went it's entire life with original head bolts. Ran a Greddy MHG using them for 15 years. Zero problems. No re-torque either. Installed and forgotten about.

You could RTFM...

Just recirculate it. The only reason you care is because you think others do when in truth they don't. It's the same with the fog light mod I've always been puzzled by. Do those who do it actually think anyone else on the road gives a shit? And since they don't who exactly is the owner trying to...

That's it. Makes the VTV into a check rather than the one way fixed orifice flow controller it was and uses the valve as an adjustment to restrict outflow. A flow control valve would serve both purposes. In fact the MBC alone might even do it. It's a God awful hack if I ever saw one but hey...

Doesn't need pictures. Just follow the description. It's a real hack though. Could be done a lot nicer using any off the shelf miniature flow control valve. Not that I would want anything holding my throttle at 2000 rpm for a few seconds...

I agree but that curve doesn't begin with doing the actual work. It begins with study. Learning the difference between heater core and evaporator would be a good start...

Ugh...

Why would you think a mhg and arps are needed on a normally aspirated engine at all? Odd stuff coming from a master tech...

You shouldn't be attempting AC work unless you know what you're doing and you clearly don't fall into that category.

It's not just a river in Egypt... Not that uncommon actually. Although I prefer the BTB test I've confirmed more than a few BHGs using an emissions analyzer on a bagged radiator neck. The long time to develop isn't that uncommon either, especially on these engines.

Not having an AFM input was a big factor and is what put the system in Fail Safe. As I've said before what good is a system that strands you when a sensor, even one as critical as the load, fails? While such protection is common today Toyota was on top of it a long time ago. Loss of load is...

There's several factors determining whether the engine will start and keep running with no airflow through the AFM. Starting isn't a big deal but whether it keeps running or not mostly depends on if the system is in Fail Safe. I once started and drove my car around town with the AFM and pretty...

^ Now there's something we can agree on...

It can't. As I said, user error. It's a DSO right? Try using it as one...

Lmao. I rest my case. User error and not just with the scope. Better towards the end though...
