MGB & GT Forum

Does anybody have experience with this type oil filter. It has an anti flow back valve inside, but does that prevent oil spillage on my garage floor when removing for an oil change? Ordinary filters always create an oil mess and I would gladly pay the extra $$ to get rid of that.

It's really no different in design(ADBV) than others so no...it will NOT prevent the mess by itself.

73 MGB. Tires: Round, black, hold air. Oil: Sometimes old, sometimes new...always slippery. Oil filter: Yellow, usually full of oil. Carbs: 2 SU HIF. Distributor: Yes. Headlights: Not that bright but bright enough. A bunch of other stuff most cars have but not really important enough to itemize. Oh, wait...it has a cool sounding exhaust with stickers on the chrome tips. Really slays the ladies...

Been using those filters on one of the Bs for over a decade. It prevents some of the mess, but not all of it.

Although I don't really worry about it(I lift the car slightly so that the oil from the filter drains without too much mess) my guess is that you can simply "crack" the filter before pulling the sump plug and that will evacuate the majority of the filter for a fairly clean removal. Maybe I'll give that a try next oil change to see if it works...

If a filter is holding oil by suction or other means, just stab a hole in it with a screwdriver before removing.

I've found stabbing a hole in the top helps a little but there is still enough oil in there to make a damn mess.

Someone here recommend I get a Form-A-Funnel. It's available at MOSS but cheaper elsewhere. After you figure out what placement works best for you it really does help to prevent a mess when changing the filter.

I'm not sure a filter with an "anti flow back valve" will produce the results you're looking for.

Just be wary of the K&N HP2004 in that some have a block off in them that came through a few years ago.

It was so effective it made it impossible to get the filter on in the first place.

I am not sure if this is the item you mean but I ordered my HP2004 just a couple of months ago and could not get it on. I ended up in communication with the Asia & South Pacific Area Manager who sent me out a replacement HP2004 plus a PS2004 (the black cheaper model) which did not have the block off valve.

There was some discussion on MGE a few years back about this issue I discovered. I take it K&N rectified the design fault but there must be a few still around that will not fit onto our cars.

You can see the spring loaded block off plates on the filters that don't fit just at the end of the thread . This plate will not allow the tube on the filter housing to go inside the filter.

Other than this I have had very good service from K&N and on this occasion they put it right at no cost to me, so still pleased.

The anti-drainback valve will hold oil in the filter, so if you tip the filter during removal it will spill over. Try to hold it vertical to minimize this, and get a rag under it before lifting over the paintwork. Those with LHD cars can use a hanging filter to avoid this issue of course.

I take some scrap cardboard and make a temporary funnel/guide to try and minimize the mess on the floor and block. It's not 100%, engine clean and a hose is still usually required post oil change.

Here's what I do. I like to drain the oil when its hot, so pull the plug as soon as I shut the engine off. Then let it drain for at least one half hour. This allows some oil to drain out of the filter (I think maybe down to the standpipe) and allows the filter and what oil remains in it to cool. Put funnel underneath and rags around filter, unscrew filter fast and flip it upside down, some oil will come out but will not create a big mess.

No matter what you do the filters seem to make a big mess. So I keep a couple of old t-shirts around or towels and wrap under the filter and then break it loose. Amazing how much oil they collect. Makes it easier and cleaner to change a filter. THEN....I purchased a tap with the same filter threads (old mind can't remember the size) and tap out each filter BEFORE putting it on. You would be amazed how poorly the threads are made. This really helps when installing a new one. Oh, I have the die also and run it down by hand once to be sure.

I used the K and N for the last two years. No issues with it and easy enough to fit etc. I have a spare on the shelf.
Last oil change I went with the Puralator just because others recommended it , and I wanted to see for myself , I did see a small increase in oil pressure with the Puralator .

I've used the K&N HP2004 for almost 10 yrs on my '74 since the oil pressure at idle drops below 10 with any other filter...still makes some mess

I use a K&N HP-1002, holds less oil to make a mess, pack around the base of the filter with rags, crack the filter and spin off quick to avoid spilling to much oil, clean up with the rags packed around base.

Works for me...!!!

I use this same filter on my 1974 MGB. I have experienced very little oil mess when changing the filter, and what little has shown is easily taken with a paper shop towel held at the base when removing the filter. I also let the car rest for 1-2 days before oil and filter change.
