 |
|
I told you guys it wouldn't take me long to come up with another stupid question so here goes...
Type 1 engine, full flowed and using an external filter. Can the original oil strainer (screen) be eliminated? Would the oil pick-up tube still function properly?
From the gallery

| You can get rid of it but it does no harm in place. |

| My 1600 is full flowed with external oil filter and I'm keeping the strainer. |

I can't in 1000 years imagine why you would want LESS protection in filtering the oil. Why would you want to remove the screen?

It seems redundant. What's the screen going to catch that the filter misses?

You never know. It's also redundant in the T4 which came from the factory with a screen and a filter, and the screen still catches stuff and should be cleaned with every oil change. With oil filtration, I'll take as much redundancy as I can get.

That's a good point

| My 3rd stupid question this week |
You're on a roll Gary  
If nuts, bolts, bearings, or anything else falls to the bottom of the case it will prevent them from going thru the pump. And if you don't have it you'll probably never pull the drain plate to inspect for any particles, sludge or whatever. Also the sump plate studs then might be too long and the acorn nuts bottom out instead of sealing.

Much better points and all well taken.

Even I would leave the screen in place, who knows what lurks in the depths on your engine. Pulled one engine I had previously assembled apart to find a fir code in the sump thanks to some squirrel looking for a place to store his winter feast. I have certainly found a bunch of other weird crap hiding in pans and sumps over the years.
I have heard of people leaving the screens off to increase oil flow, but I have never heard of anyone actually having a starvation problem with them in place.
I would leave it there and then just not clean it more than once every 50K or so after the initial break in period. |

Just want to reiterate the point made here, with some pictures of modern oil pick-up tubes. Seems like a good plan to keep the screen with filter, since that engineering is still used. I clean these when replacing oil pans, so with a filter, they don't need regular cleaning, but also not forgotten.

Old German engineers also didn't bother to use a filter on an engine sold well into the 1970's. Inexcusable oversight if you ask me. |

aeromech;
You only asked what many of us have wondered about. I changed my oil, filter, and cleaned the sump screen just this past weekend, and wondered that very thing.
I too anticipate your next silly question. And it's OK for you to ask them, 'cause you're not a noobie!
