Glad there was no damage done at least!

That’s the ticket. Might try putting it in the weed whacker.
I set the bucket outside. As of this morning, half of it evaporated. _________________ 1800 Type 4 Berrien 295

Dang, that's a well-sealed engine that it didn't evaporate before! _________________ Two Bugs-

Leaks are a pet peeve of mine, to the point that it was irritating to see gas weeping from the cylinder head to exhaust joint. _________________ 1800 Type 4 Berrien 295

Minimal leaks, better efficiency, right? _________________ Two Bugs-

Biggest thing for me is having a dry engine. I can’t stand an engine that doesn’t stay dry. There is no reason a fresh engine shouldn’t go 10 years before seeing any sign of oil weeping from the case.
At any rate, seeing as how this was just a big of gas from the exhaust due to operator error, I am not too concerned… not enough to pull the exhaust off and anneal the copper gaskets. _________________ 1800 Type 4 Berrien 295

I should also say, 5W-20 seems to be more reasonable than 10W-30 oil I was previously running. Better oil pressure when “hot.” Not so high any more. I always build my engines on the tight side of the spec. The 10w-30 was over 40 psi at idle when cold, and 20 when hot. The thinner 5w-20 brought that down to 30 psi cold at 15 hot at idle. I also don’t push 60 psi while cruising anymore. I am down to about 40 when just driving down the road normally.
Too much oil pressure does no good. The oil cooler bypass opens, and the oil filter internal bypass opens…so basically no filtration accept at idle. Now more of the oil gets filtered while driving around. The filter should only bypass with my foot into it now. _________________ 1800 Type 4 Berrien 295

The filter bypass is a differential pressure bypass and should not activate unless the filter element itself is restricting flow. This should only happen in very cold weather with thick oil or when the filter is plugged with dirt. It should never ever happen under any normal conditions regardless of engine rpm. Even if your oil pressure hits 100 psi, as long as it is 100 psi both sides of the filter the bypass valve in the filter will stay closed. _________________ We had the stone age, the bronze age, the industrial age and now we are in the age of mass deception and mind control for corporate profit.

Yes, it is a differential valve, but it is pretty low pressure. Most oil filters bypass at 10-25 psi depending on the model. The oil filter I am running is 12-15 psi differential, which with a short filter, is pretty easy to hit. It is pretty normal for a good chunk of the oil to not go through the filter while cruising. It pretty much all gets filtered at hot idle, but the more rpm you give it the more the filter allows to bypass. _________________ 1800 Type 4 Berrien 295

If that is actually the case then "full flow" oil filtering does not really exist. It also means that an oil filter is just a dirt accumulator that dumps it's load of dirt into the engine at will.
Step us through the discovery process that has led you to this understanding please. _________________ We had the stone age, the bronze age, the industrial age and now we are in the age of mass deception and mind control for corporate profit. (The mass media age) |

1) The oil filter manufacturers list the bypass opening pressure specifications.
2) Cut nearly any automotive oil filter apart, and you will find the bypass.
3) you are correct, “full flow” is a bit of a misnomer… 100% of the oil goes through the oil filter canister, but not all of it gets filtered through the element under all circumstances. This is also why you can find all kinds of crap embedded in the bearings after an engine wipes a cam, cracks a piston/ring, rod lets go, etc… especially at high rpm, a lot of oil can go right around the filter element. It isn’t a 100% filtration all the time deal.
4) True full flow systems exist, but usually in the industrial or stationary diesel market. They are also more common in hydraulic systems. Pretty rare to see in any passenger car. I am unaware of any current passenger car on the market that does not have an oil filter with an internal bypass built in.
5) It doesn’t really act as an accumulator and dump dirt from the element when the bypass opens. Remember, when running there is always pressure on the filter element holding particles to it, and it doesn’t ever back flow to flush dirt out.

Last ride of the year. Pretty soaked by the time I got home. Poured cats and dogs about 10 minutes after the second picture. 20 minutes home in the pouring rain. What a way to end the year.

Richard, that they are. I’m really happy with them. They seem to get the front end around the corner better than most heavy 7.00x15 tires, or trailer tires. Tracks really nice. _________________ 1800 Type 4 Berrien 295
