Best oil filter with sandwich adapter and plugged bypass?
 

While all of the fun is going on on the oil pump thread, I thought I would try to start up some trouble with my own thread. ;)

I am running a Gen VI block with the oil bypass plugged. I'm also running a thermostatic sandwich adapter with #10 lines going to/from my oil cooler, with the filter mounted to the adapter. I set it up this way in an effort to eliminate the extra hoses and fittings needed for a remote filter adapter, but the down side is that it makes it tough to fit a large filter in there.

I had a smaller filter on there for space purposes that became flow restricted and resulted in a drop of about 20 PSI oil pressure. I am going to try a larger WIX or NAPA filter on there, but someone mentioned in my other post that I should consider an oil filter with a bypass built into it in case the filter became clogged. Now I realize that if my filter gets clogged with metal, that will be the least of my problems, but I have also read that the cellulose filter media used by many filter makers can swell and become clogged water going through it. I'm not sure how much moisture would cause this, but it is not unexpected to see some condensation, so I guess it's a possibility.

My two questions boil down to this:

1. Should I find a filter with a built in bypass, and if so, can someone recommend one?

2. Should I look for something with synthetic media?

Thanks in advance!

Well crap, I guess I need to start an oil pump thread so I can make some new friends. :p

Amsoil Ea oil filters.

i like and use the wix racing filters.you answered your own question about a filter with a built in bypass.btw,i never heard of that before.if you plug up the oil filter the show is already over.

if you do that plan on a total train wreck,lol.

Wish I had an answer for you. Eddie is going to plug my bypass so this may be an issue I'll be dealing with. Need to remember to ask Eddie about the issue

I generally run a baldwin b1335 (iirc) which has a bypass build in. I specifically got a filter with a bypass because I have a plug in the block bypass. I also liked this filter because it had a higher burst pressure than most.

Baldwin are very good filters as well. I am dealer for them plus sell their fuel water sep filters. Hastings filters is also owned by the same as Baldwin.

If you don't want to spend the $$$ on say; System One Billet filter with a 35 micron element and non bypass. Use a Wix racing filter by all means. I always use a Napa Gold, so to catch all the small particles at initial start-up in the boat to catch everything after coming off the dyno, with all the coolers and hoses in place. Water coming into the picture affecting the filter, is a problem to start with, unless I misunderstood you.

This is a good subject for thought .I think a lot of filters now seem to be more about price point and effectiveness in the light truck market than us marine folks with other oil filter needs like slow oil temp rise and plugged bypass ect .have been wanting to dig some out of the drum and cut open to compare for a while .the best set up I seen so far was factory marine power remote dual oil filter ,502 gen 6 , still had 30lb bypass ,still flowed all through the filters on cold start verified with dist housing and a stout air drill

I been using this exact filter as a dual filter setup for over 20 years with no regrets.

there's no way in hell I would try to use the filter on a block mount..what a royal pain in the a$$ in every boat set up...I used a Eddie marine block adapter, #10 lines, a moroso oil filter mount w/a napa gold/wix tall filter and a Eddie marine large oil cooler...

ez, getting to the filter is not too terrible, just wish I had a little more room for something taller. Spinning it off is no problem - the trick is manuevering it out of there. If I had it to do over again, probably would have gone with a remote filter, but having the stat built into the adapter, along with eliminating a pair of 90's and about 3-4 feet of hose sounded like a good idea.

Now it would definitely be a "no-go" in a twin engine application.

till sounds complicated ,so the 2 front cooler ports are capped ,and its all goin down off the filter pad ? The extra lines and clutter won't win any awards for the least clutter but you get some extra oil capacity bonus .and you can still rightfully pull the thermostatic oil control card

It has two ports that go to the cooler, regulated by a built in stat. Oil flows through the filter full time.

Who's product is this, Earle by chance?

That's not an Earl's. Earl's is a billet piece.

It looks like the one I got from Jegs. I did the same thing. The block ports are to small at only 3/8" and the adapter is 1/2" threads with the built in stat. Last year when using the block ports to -10 lines then my cooler which is 3/4"( or -12) I would raise temp to 240 with a 1 to 2 minute wide open run. It would cool right back 200 in 5 minutes at 3200rpm. The sandwich adaptor in my donzi I can still run the bigger filter and my oil temp doesn't go above 210 and regularly is at 180 when running easy/ normal. I do like the adaptor I think it works well for my application. Also I can go up on that and line size if needed since the cooler could take more flow. In short I think this will work for you as well.

Now on your filter question. I think you guys are making it to complicated. I run the Purolator pure one filters on everything I own. 25 years on a 350 Mag. For the last 12 have been mobile 1 oil with pure one filter. I took the heads off this year to check it and it's perfect inside. 25 years at an average of 50hrs per year. That's a motor with no oil cooler and temp sensor on the oil. Yes it's a black motor. However thats one oil change per year and my father and I running it like we stole it. Just run a good filter, block the bypass and run good oil. If you keep it pinned everytime your out change your oil more often. If it's put together correctly it will stay together. Just my .02.

take a look at kandpengineering.com I'm running one. reusable, filters to 35micron and they look good.


And I just realized how old this thread was...
