Very wise decision to disassemble the external t-stat. If the engine to which it was previously attached experienced a bearing failure, that bearing debris can reside in the t-stat housing and damage the next engine Great job by Tom once again in sharing his fabrication skills and how-to process!

Thanks and I agree about erroring on the safe side. The thermostat oil does at least get filtered before it goes through the engine again. You know what is worse is the oil tank. Because dirt or debris in there goes direct to the engine.

the rare and wonderful people like you offer at least a glimmer of hope for this depraved species !

Thanks! Mac will be running again soon!

Those large cover screws are “ Hi Torque fasteners heads “ just like the oil temp and pressure relief on a 356. They are available in 12 sizes (HTS-xx) They were designed to keep the applied torque at 90 degrees to the threads even if the applied angle is off. The thermostat is a wax motor, very reliable and has a variable flow rate, bases on the temp. Nice job on the explanation. Rule 31 “ NEVER put a regular screwdriver into a high torque slot”

I've seen many damaged oil relief plugs on 356/912 engines! Rule #32 is don't use a pipe wrench on these things either! I've seen replacement covers with a hex nut on them for easier removal. I like your explanation of the torque not being square to the threads. These don't seem like generic covers because they have features on the inside to hold the spring, etc.

Another great video from my favorite Porsch restorer.,

Nicely done. Doesn't get old, at least not for me. I enjoyed the chilled organ tunes too 🙂

Will do! Mac 2.0 coming soon!

FWIW save yourself lots of time.. buy coin slot bits in 3/8 drive and bob’s your uncle on getting the plugs out! Aircraft spruce is a great resource for them.

Great video thanks for sharing. Headed on to the shop to work on my 911. -Spanky

Tom. That a hi torque slotted screw like the oil bypass on your 356

Clever!

At this point, it feels like you are an archaeologist, taking apart “ancient” artifacts and preserving their original state.

Ha ha. You know how expensive and rare this stuff is now.

Another top job! Do you need to put extra oil in the engine to compensate for oil lines that run to the front of the car versus a model without oil lines

Thanks. Yes more oil is needed and this is why the oil level is always checked with the engine running and warm.

wait, I got lost in the sequence of events. the 3.2 engine hasn't been installed in the MAC, right? so as you say you will be installing thermostat, there was none when it had the 912 engine? or it had it different or is this for preventive maintenance?

Easy to get lost as I've been skipping around a lot with various projects. I'm almost ready to put the 3.2L in MAC so I'm renewing the oil system. Mac's previous 912 engine doesn't utilize the front oil cooler or thermostat at all. The 912 is a wet sump oil system and the 911 is a dry sump with an external oil thermostat. Since this thermostat was used, I wanted to check it before it goes on Mac.
