Oil filter...
 

I cut open the standard Merc filter on my boat to look for any issues as I've heard that a little reversion can fubar a filter. Does this look as it should?

You will need to post a cross section view with the media removed from the steel filter housing. So you are currently having reversion is what you are saying? Yes, moisture can damage a filter, however bearings, valves and such would concerm me much more. Also, there are many filters that perform many times better vs the brand you are using.

I noticed a little drop in oil pressure and read that when the pleates stick together rom moisture it can cause a drop in pressure. Less than 20 hours on a new Eagle 502. Never ran it hard yet.

I can get better pics tomorrow.

The oil itself looks and smells like it just came out of the bottle.

That's why I made my own housing for these. The hp6 on the dyno started to do that.

That is a very cheap filter. What kind of oil are you using? It looks cheap also.

Brad Penn oil. The filter was put on by a mechanic that I'm no longer using.

It reminds me of the old group one poor non detergent motor oils that would sludge up and varnish up the complete internals of the engine. I would like to know also what motor oil you are you using ? I would drain your motor oil from the bottom of the oil pan to see what in the world that looks like.

Also open up the pleats of your oil filter and run a magnet thru them to see what it picks uo. I understand not all internal engine pats are magnetized but you would be surprised what the magnet might pick up if you have accelerated a lot of internal engine wear. Also after you completely drain your motor oil - I would run your magnet thru that as well.

I say this because your pic of the cut open oil filter looks like possible metal trapped (slight metallic color) as well but it could be the pic to. Also besides the oil you are running as to what is it - it looks like you have some water intrusion and or heavy condensation built up and fuel dilution. Also would wonder what are your engine and oil temps running at ? Possible a very cold & rich running engine.

I know you said standard merc oil filter but was it a fram oil filter - I see orange in the pic

What was used to cut the filter open ?

Will do. There's kitty litter on it and I cut it open with a metal sawzall blade.

180* water temp

Brad Penn oil

And that's why I asked. The metal appears 'ripped' and the top of pleates the same (ie:'ripped' too), making them look horrible. That skews the picture we see. IE; if it was cut by by an oil filter cutter or similar it would not look the same.....and that's the difference that makes it impossible, IMHO, to judge anything by looking at that pic. Probably just as hard in person.

You need to use an oil filter cutter tool so you do not get all those very fine metal shavings (metallic color) all over the pleats and down in the filter from cutting open with a sawzall or cut off tools. We use oil filter cutters all the time and to cut open all fuel filters to.

Plus the oil filter cutter tool cuts off just above the base, Not jagged cuts into the pleats

Good pic of more properly cut open filters:
1st, a typical filter cutter, although many other styles....pretty much all styles use rolling cutting wheels like a can opener:

Ah yea, in light of that the sawzall hack isn't going to help much. ��

Why does it look like a cheep filter? Looks like a GM or Mercruiser Plastic insert? How to check for cheep oil?

By looks.

LOL !

Sorry Black Baja. That part was funny !

This is the oil in it now.

Your problems I don't think are oil related. The oil filter is collapsed. Look for brass if none run it again and check oil filter.

Kinda tough to tell if it is actually collapsed after murdering it with a sawzall, but I suspect it was as I have a ZZ502 cam with OEM manifolds so it was definitely sucking water. It was a mercruiser filter though.

The bummer is I have a tubing cutter good for that size. Bummer.

No doubt that its pushed together. Just look at the rest of the filter. Are you salt water or fresh?

I will say in pic 13 - the Fram with carboard end caps and then in the bottom pic - the 3 middle oil filters with cardboard end caps are surely the cheapest junk filters you can buy. I can see that one a mile away. Also uneven of pleat distance counts as a sub par& below oil filter. The same goes for your spin on fuel water sep filters.

Good eye by SB on the pleats being cut because at first I thought some it was oil that was thicken, in the pic it sure made it look that way.

Fresh with about an hour in some brackish stuff.

brad penn oil is some great stuff, just switching to it myself, how long was it run on this oil/filter ? like said before going to need a filter cutter to really tell much...are you running a oil temp gauge ?

They look like CAT fuel filters for the big diesels. What did you use for the housing?

If he has water in oil wouldn't he be able to see it on the dipstick in the form of a milkshake color. You could always do a S.O.S (spectrum oil analyst) on a oil sample. That is what we do on all of our motors. It will tell you if you have a smaller quantities of water or metals in the oil that you can not see with the necked eye.

Machined up some aluminum to make them fit. They can handle big flow without a problem and easy to inspect. Plus no metal tube in the middle. Hydraulic 10-micron filter.

Mobil 1 Oil Filters use a synthetic filter media and will not swell up with moisture like filters that use a paper media.
I think K&N also uses a synthetic media

Mobil one and K& N oil filters internally are the exact same filters - the exact same - one costs a dollar less. If your are worried about your filter media - look into system one filters.

www.system1filters.com

I picked up this unit that has a solid fan club.

Still a paper media but Wix is a good filter. I like Amsoil EAO filters to. Baldwin is a good filter especially for the money compared to the wix internals.

Cool. I did ditch the manifolds for some CMI headers that dump 6" from the transom so my reversion issues should be done.

Yes, both made by Champ laboratories. I agree that the WIX racing filter is ok, however I think quite a few people forget it has a 60 micron rating which is pretty lousy. It flows more, however not much more than what the mobil 1, K&N and Royal Purple oil filters do. These three offerings(champ labs) are in the 18-20 micron filtration range, although they do have bypass valves built in.

The mobil one/K&N filter is a hybrid material comprised of cellulose and synthetic glass fibers. This gives it high flow and excellent dirt capturing ability. The Royal purple filter is a 100% synthetic glass media with a pleated metal reinforcment webbing. Essentially very much like the amsoil filters. These are some of the best oil filters you can buy.

Imo system one filters are for racing engines that see frequent tear down, not a marine engine you expect to get many hours of use out of. Their micron rating is even less than WIX racing filters if I recall. I would just pick one of the 3 above and be happy. Any further concerns with water in the oil maybe consider a used oil analysis.

How about donaldson oil filters? I know in the big truck world, donaldson is a respected name in filters. Heck, alot of light duty trucks had donaldson air filtration systems on them.

The part number for our typical "wix 51060" is Donaldson # P550964. In donaldsons catalog, they show it to be 99% efficient, at 35 microns of flow. Saw them online for about 5 bucks a piece.

Quote from amsoil's site

Increased engine emissions control and tighter tolerances within the engine require high efficiency filters.

Donaldson P-Series filters are typically constructed with cellulose or synthetic blend media for high efficiency. The media is embedded deeper into the sealing plastisol than conventional filters, allowing better sealing longevity. The lube filter can is constructed of heavy gauge steel, with many models having domed tops that provide superior pressure fatigue performance. The center tube allows more flow without compromising strength, and the louvered design eliminates tearing during pleat movement. The can and base plate are assembled using a fully tucked seam, roll-formed threads, a nitrile sealing gasket and a compression spring holding all the components in place within the filter.

Donaldson actually developed the technology that Amsoil is now using in their filter line. Donaldson did quite a bit of R&D with the United stated military when the M1 Abrams came into service. Turbines running in a sandy hot desert need specialized filtration.

Remember that most of the numbers are "nominal" not "absolute". I'm almost certain the wix racing filter is right around 60um. I will double check just for the sake of not leading anyone astray. Wix makes great filters, IMO the racing filter isn't one of them. With filter technology as it stands today, why anyone would opt for a cellulose filter that if effectively a rock catcher, is beyond me. In most cases, a synthetic glass media will outflow a cellulose one. Dirt catching capability wise, glass media always wins. Only downside is cost.

Devil's advocate with a note that I like all the information given:

Anybody ever lose a boat motor because the oil filter didn't filter fine enough ?

Oil pan after 300 hrs of use using the Wix Racing filter . Looks pretty clean and all bearings were in great shape .

With the cost of a rebuild, why would anyone ever skimp on oil or filter! I personally want
the best there is and consider it money well spent.

Oil filters are about the only engine related part we didn't fight about yet this winter so hurry up guys , time's running out . :pacifier:

AMEN.

I doubt you'll receive any argument to that.

Boogie Woogie is not here.
