I'm going to install an oil bypass system on my 84 300 SD and want to know where do I tap into the oil system?

OE filter already has a bypass section installed.

If I was going to put one in, I'd tap into the pressure sender at the back of the block.

The stock filter must not be a low micron filtration because the oil gets dirty in only a couple of hundred miles. Does anyone know what micron a stock filter is?
Baldwin bypass filter is rated at below 2 micron. Cheap insurance.

It's called soot. It's in the nature of a Diesel motor.

Yes, I'm well aware of soot and the nature of diesel motors.A bypass filter filters the soot out of the system. Common knowledge.

Search for ForcedInduction's thread on this very topic. You will be pleased.

Don't think it's worth your time. It is still going to fill up.

Go over to www.dieselstop.com and do a search. Excellent add-on.

Standard Filters.....20-40 microns

Bypass or premium filters generally....... 5-20 microns

I'm well aware of their ability to filter further.

Baldwin is below 2 micron. Most are at or below this. This is cheap insurance for a longer engine life.

I wonder which would give more benefit -- a bypass filter or a filter housing that could be filled with oil during changes so that you don't have to wait what seems to be a long time for the darned stock one to fill up!

A bypass filter does not replace the engines original filter, so the answer is a bypass filter since you could do both. Over time a bypass filter will allow you to use less oil, as the frequency of oil changes drops. You'll do a favor to the environment, spend less money on oil and filters, and your oil will be cleaner. If you keep the filter on engine for over many years you come out well ahead on many fronts.

Thank you!

I understand all about filtering the oil, and so on and so forth. Now what about the fact that oil viscosity does break down due to heat and shearing pressures? How does leaving oil in for an extended amount of time equate to longer engine life? So it seems we can achieve clean oil that is used past it's prime. Am I missing something?
