Isn't that what your doing already?  |
Removing the spark plug and adding a good a squirt or 2 of engine oil before a compression test should tell you if it's a valve or not:
The oil temporarily seals the ring area, but not a leaking valve...
I don't know what it says about a blown gasket or warped head.
There one generally looks at (oil added) flow from the crankcase vent and white oil etc.
This is a very old thread in the Unicorn corral.
"Looking for old smokey (car engine) for some scientific experiments"
Might find someone, besides me, willing to try BA before they strip down an old engine to rebuild it.
It seems that the top thought is:
"if BA is so great; why aren't all the car makers putting it in their engines/oils???"
Lets say you sell Anti Dandruff shampoo.
you have 1 000 000 loyal customers buying a bottle a month.
You make $1 per bottle for a cool $ 1 000 000 a month.
I come along and say: "Add this too your shampoo and Dandruff is permanently cured after 4 or 5 washes!" (cough-Colloidal Silver-cough)
Poof! There goes your $ 1 000 000 a month!
Car/engine manufacturers are in the game to SELL a lot of engines/cars, same as anti-dandruff shampoo makers...
Anything that makes engines, gearboxes, diffs, wheel bearings, etc last indefinitely is akin to Satan himself setting fire to their whole business.
ie: They are very likely to 'kill the messenger' rather than embrace him.
Where are the electric oil pressure before start systems?
Where are the coolant level alarms? (no water = no temperature measurement sent to the dashboard temperature gauge. I NB that some cars do now have coolant level warnings?)
A little oil pressure light is often missed too.
Race engines always have a very loud buzzer or similar on the same circuit as the warning light, built in.
Often the little warning light is also replaced with something more akin to the sun!
Only VW cars has a 'soft' buzzer as far as I know.
"Oh it's my fault because I never noticed the dim little warning light..." is a crafty scam to sell more engines/cars!
