my shaft is too long. take a look at it

-
went down to the parts place this morning for some parts. Picked up a Wix 51515. come home and put it on. works fine and looks good on there. guess I will go with that this time. don't think I could do the yellow one on here.

The drain back valve is irrelevant here. The filter is upside down. If the tube is eliminated, then the oil will drain back through the galleries and ultimately into the pan. What's the big problem with running the correct filter?

Ok,that's what I thought. So, without the standpipe the pump needs to fill the filter before anything goes to the engine?
Now part 2 of my question. On a '75, I am 'assuming' I have the shorter standpipe. Is there any issue having the shorter pipe with the longer filter? Is it still waiting for half of the filter to fill with oil on start-up? Or will it start to push out what's there immediately?
 
zkx14, how long does it take your oil pressure light to go off? That light is on the outlet side of the filter so the filter has to be filled before that light can go off. If you have the long filter and short standpipe, then I woudl imagine that the pump does take a bit longer to fill the space. A good condtion pump will fill that extra space pretty qucikly; my nicely rebuilt pump and newly rebuilt engine with the long standpipe and filter takes <2 seconds from a 30F cold start for the light to go out. Before the rebuild, it would take 5 more more seconds with the same filter type; the oil pump was just not up to it and the pickup screen was pretty clogged.

The filter in this engine can be drained in 2 ways:
- Via the oil galleries as they leak down through the cam bearings and crank main bearings; these are all BELOW the filter and only the standpipe keeps oil in the filter in this case. How much and how long this drain-down path takes, I can't answer; I would think that is pretty slow as air has to work its way back up through the bearings and oil gallery.
- Via the oil pump and pick up tube if there is no anti-drainback valve; the anti-drainback (flapper) valve is relevant regardless of the filter's orientation. The anti-drain back flapper in the filter inlet (the outer set of holes in the filter base) is the only thing to prevent this. How tight the antidrainback is over a very long term, I can't say. (And there needs to be air drawn back past the oil gallery to allow the filter to drain in this way.)

Never timed it, not long- maybe a few seconds. I'm not thinking its a big deal or anything to lose sleep over... When I got the car it had the long filter on. That's what I put back on. I knew it was supposed to have a standpipe,which it does. I never realized there were diff lengths. I'm just guessing by year that I most likely have the short one based on what I am reading. Just wondering if it's any issue to mismatch them. Obviously it does not work the other way around, as found out by the OP. i will check the time on oil light and see for sure how long the pipe is at some point. If I can save it a couple seconds dry run each start, I would at least keep an eye out for a longer piece.

It will only drain until the top of the tube is exposed, then it will stop. I don't see a problem with it.
 
What is the big deal about using a Mopar filter anyway?
They aren't built by them, and the Wix is a good filter, why over think this?
Just for a name on the side of a filter?
Sometimes people worry about too much stupid crap that doesn't really matter......
 
Nobody is making a big deal about anything. I don't know how you guys do it in Canada, but here in America, it is the home of the free. That means I can put anything on my car that I want. I wanted a Mopar filter. It isn't stupid crap. If you wanted to paint your car pink, would you like someone telling you their opinion about painting it pink. ACTUALLY.........my wife wanted a Mopar filter on her car. This is her car. and you don't want her to tell you what she thinks about your post. So I wont show her this. BTW. I put a Wix 51515 on it. Is that ok with you.

I'm sorry trudyduster I didn't mean to get you worked up. I just thought you mist the post that had the correct Mopar part number for the tall oil filter. I personally like to use the Mopar filters as well.
 
You have to be tired before you can be re-tired.....
