Delvac1 was available long before Rotella T 5-40. It was a fantastic oil then. We tested it the Bradley Fighting Vehicle transmission in a test cell environment in the 90’s with extended drain times of 8 times normal with minimal shear.
I’m sure it’s still ranked in the top 3 brands.

The motor oil Geek responded to the GM RECALL recommending that 0w40 be used rather than 0w20.
0w40 protects crankshaft bearings much better than 0w20 because of thicker film thickness.
The sole reason for GM recommending 0w20 was to raise their corporate average fuel economy which raises...
Check the thermostat for proper operation it very important that the engine gets up to temperature.
If the radiator gets warm as soon as the engine is started the thermostat may be bad.
Top of radiator should be hotter than bottom by a significant amount.

Dry rusty fasteners can be very difficult to install & remove. A dry fastener will often not torque up smoothly often resisting torque then snapping loose as more torque is applied which can be painful and break tools.
I always clean & lubricate my lug nuts or screws before assembly.
I always...

With today’s political environment I briefly started thinking is this the big one??😬
Stop, relax & think logically.
Start at the power source, no dc power to inverter so I check...
I knew better, I really did!
I did a major no-no & I’m lucky it wasn’t worse.
Was boring 1-1/8 holes in a 2x4 to make a table for mounting my pipe clamps for a glue up station & my hand was pulled into the bit.
The photos tell the story no explanation needed.
No nerve or tendon damage...
I’ve always known it’s a big no-no but I’ve never seen/heard of the specific damage, could you elaborate.
Injection pump, piston cylinder damage?

Building a load bank is relatively easy and affordable. I use portable space heaters for my testing.
They are typically 1400 watts and inexpensive when you consider the consequences of not loading a generator properly.
I have 3 similar to this and 1 with three heat elements of 2.5kw each...
What was the exercise cycle?
A proper exercise load would be 50% for 30 minutes minimum which may not be possible unless there is a load bank in the system.

I found a 3/4-10 bolt & nut in my catch all pile and put it up to the acme the thread and it is a perfect match at 10 threads per inch and NO the nut does not turn on the acme rod.
