Blow By Solution ????
I found this while doing a search on blow by. All you mechanical engineers, will this device work on a diesel? Please let me know.

I would tend to be sceptical about those claims..............and anyway I don't think it would work as there is no vacume source on a diesel this would work with like a gasser
But I could be wrong.

Mensa ???
I knew a genius would offer a solution!! How many Mensa members frequent this forum? Thanx for the reply Doc, I was kinda figuring with no natural vacuum in a diesel, this would not work....

I tend to be sceptical of anything that offers a miracle cure, And that one seemed to be geared to the people with worn out engines and seemed to promise a bolt on fix for what really is need for a rebuild.

based on my experience as both a Mechanical engineer and Physicist, no. That's not to say that this is specific to a diesel. Sure, a diesel has much higher compression and thus harbors a greater potential for performance degradation via blowby than a gasser. But fundamentally, evacuation of any IC crankcase requires power. This power comes from the operation of pistons and valves which pull gases from the crankcase. Unless this device has a big pump in it, it doesn't do what it claims. The oil companies don't really buy the rights to every engine invented to run on water. The principle violated here is conservation of energy. In non-nuclear reactions, energy in equals energy out. Energy may certainly be converted into forms that we differentiate between, but energy is conserved. Period.

Just a thought
Whew..... But, if you have excessive blow by, would it not entail having excessive smoke coming from the tail pipe? I just can't see blow by being a silent killer.

The rubber tube ontop of the valve cover next to the oil filler cap is where crankcase fumes (blowby) are pulled into the intake from. Excessive blowby is when exhaust gases leak into the crankcase (usually past worn rings/cylinders/pistons) enough to cause problems. Some blowby is normal

That clear line on the Vacume pump isn't vacume, its the pressure vent from the output of the vacume pump. Think about it, it sucks on one end creating the vacume this is what it dumps out. Think a minture shop vac. If you DID hook up to the vacume pump on the vacume end with the crank case vapors and suspended oil youwould kill the diaphrams and check valves in the vacume pump post haste.
Besides it doesn't have the capacity to suck the crankcase to a negative pressure level with the motor off much less running, and then it would be a huge vacume leak and none of your accessories would work even if it wouldn't self destruct (the vacume pump)
