Observation on Filter Placement

[TheLoneRanger]

Every time I change oil, I think about this: The wife's Explorer 4.0 has the oil filter mounted straight up, with no chance of drain-back; the filter stays full of oil at all times. My Cherokee 4.0 has the filter mounted at an angle of about 225 degrees, with the filter opening pointed down. This is an optimum position for possible drain-back, it seems to me.

If we agree that most wear happens at start-up, would the Explorer engine last longer than the Cherokee? (Everything else being equal)

It seems like the older engine designs (Chevy V-8, etc) have the filters mounted straight up, while the later designs have them pointed anywhere. Maybe this is a factor of better designed oil filters....or maybe it just dosen't matter?

Vertical mounting still needs an ADBV

I do know that on my girlfriend's ex-Plorer , the oil light goes out a lot faster than on my Civic del Sol, which has a sideways filter.

It was especially true right after an oil change, since I could fill the Explorer filter completely. I think the filter held more oil than my car's oil pan.

The full flow filter on my Camry is almost upside down. It drains completely at shut down. I haven't heard any rods knocking yet. It doesn't use oil. It runs like new still at 162,000 miles.
I don't know who came up with the idea that when you start your engine there is no oil on the parts.

ur saying that filter light goes out u mean after an oil change right...my moms car does that. i think the differnce with ur wifes explorer and then the civic is that it is import and domestic. domestics run on lower oil pressures than imports. thats why it takes longer..i notice this between my moms mercury villager and my accord. my light goes out quick on my accord, but the villager takes about 10 seconds right after the oil change. i think its that since the oil pressures are differnt in domestic and import that it takes longer to fill up the oil filter.

This characterization is a little outdated. GM is the only domestic car maker that is still producing a significant number of OHV engines. Ford and Chrysler engines (with a few exceptions) are OHC or DOHC.

Yes I know, and even the Explorers have been using OHC for a while now... I just notice at work that cars with OHC make a lot of noise after starting it up after an oil change compared to OHV cars.

My 300M doesn't make any unusual noises on start up after an oil change.

OHV=overhead valves operated by pushrods, with the cam down in the block.

OHC=overhead cam (i.e., the cam is mounted on the top of the head(s), directly under the valve cover). The valves are operated either by bucket tappets or roller followers. No pushrods.
