Gillettealvin,
I have been following this thread all along, and am intrigued for several reasons – mainly because I have a 46 P-15 project I started years ago, and had overhauled the engine now about 30 years ago. The car has sat ever since. It has never been run after the over haul – I have just turned it over a couple of times (by hand, with a crow bar) every 3 years or so when I would be visiting my folks again. (Shortly after the over haul I met my wife, we married, and served as mission workers overseas until moving back 7 years ago, but “back” to a bit over 900 miles from my folks, where the car is. Expect to move it here sometime this summer, and revive the restoration.) It was a frame-off restoration, so I knew that the engine would not be run right away, and so we oiled the top liberally during assembly, and also poured ATF in on top of the pistons.
During that time I worked in a plating shop, and since we moved back to the US I worked for several years in a powder coating operation, so I can follow the changes in cleaning methods you talked about.
I’m wondering specifically about the type of acid used in the chemical strip you mention – I would guess it is phosphoric, not muriatic? Talk about steel rusting before your eyes – Muriatic acid is fast at stripping rust, but steel also begins rusting the minute you take it out. Phosphoric, on the other hand, is really slow, but it produces a coating which protects the steel from rust almost indefinitely. (I have an extra P-15 front engine mount which I had stripped and never painted. It has been like that for these 30 years, and it is not rusted at all.)
But my question is – could a person not just flush the engine, with say, ATF, before starting it, and then change the oil really often, or perhaps reflushing from time to time? I’ve got the blues to have to do so much of the work over w/o ever running it….
