I have read Amsoil makes a swivel fitting for this. The only one I find on the Amsoil website is a BK-11. Is this the one? Also, what other parts will I need to use this with my plastic cap?

Can we assume that you're using this with an Amsoil setup??
IIRC, the part number is BP-89. It has a 1/8 NPT female fitting for the inlet. On my plastic cap, I tapped a threaded hole for it, but you can just drill through and secure it with the provided locknut.

Dave L,
OK, I see that part on the Amsoil parts list. Can I buy a 90 degree elbow for it at a hardware store? Thanks much.
Gary,
After much research and consideration, I decided to try one of Ralph's Motorgards. Called him and ordered it this morning. Still undecided if I'm going to T it off the oil pressure sender or use a sandwich adapter, but either way I would like to return it to the filler cap if that will work. Ralph says some vehicles don't like that. Only one way to find out.

Diesels are what you really need to be careful with. If the oil gets sucked into the intake stream the engine will just runaway. Otherwise it's all a matter of the PCV system and how it's setup. If it's an OHC setup ..then no worries. Lots of oil slinging around anyway. With most engines it's no worries ..but some will have issues.
You can get a 90 degree elbow at a hardware store if you don't need a swivel female fitting (i.e., if your hose has the swivel connections). I bought my fittings at the hydraulics supply shop where I bought my hose. If you can't get what you need at the hardware store, it might make sense to just buy the fittings from Amsoil when you get the BP-89. Adding them to the order shouldn't change the shipping cost.
On my application (Subaru Forester), the PCV valve is well separated from the oil filler tube - and so far no problems.

It has always been easier to tell people not to return the oil to the valve cover than explain the danger of returning the oil on a leaky intake valve seal or where the crankcase ventilation system can pull the oil up into the intake manifold or air cleaner. On a Ford V6 I teed off at the oil pressure switch and put a self tapping hollow bolt in the valve cover next to the fill cap. On a Chevy 305 I returned the oil to the exact middle of the valve cover opposite the PCV valve. At work I returned the oil to the valley cover with a self tapping hollow bolt on a Detroit 8.2 engine. Its heavy sheet metal under the intake manifold. On a 8.3 Cummins I used a self tapping hollow bolt in the fill neck down on the side of the engine. There is also a fill cap on the valve cover. My 55 Studebaker had the factory installed bypass filter returning the oil to the oil fill neck. The fill neck dumped into the valley under the intake manifold. Back in the 60's Frantz and Motor Guard would sell you a 3/8" hollow bolt to replace an intake manifold bolt on most GM and Chrysler V8 engines. They also had hollow bolts for other engines such as the VW Beetle. You just have to look it over.

Just called Amsoil- the BP-89s are on back order. Is there any other source for the oil cap swivel fitting?
I think OilGuard offers one, but it is not ofered separately on their web site. You could call them.
I haven't seen it, so don't know how it compares to the BP-89

Oil Guard and Amsoil have the same type of fitting for the oil filler cap. It's a 90 degree brass elbow with a line that goes to the filter element. I do not know if you can buy this separate or if you have to buy the entire sustem. I have the oilguard. It's a pretty nice system. Check out www.oilguard.com

Just spoke with Oilguard last night. They do NOT sell the oil cap swivel fitting separately. They sell only the machined aluminum oil caps with the fitting already installed. Also, did some extensive internet searching, and the Amsoil oil cap swivel fitting is the only one I could find. Looks like they have the market cornered on that part. I sure would like to be proven wrong on this.

Received my Amsoil oil cap swivel fitting today. Need just a few more 90 degree elbow fittings and hope to get the Motorguard hooked up tomorrow.
Because the Motor Guard is a compressing type filter you don't need a tight roll. Unroll enough paper so that you can slide the roll in with a couple of fingers. The core will crush so it doesn't hurt to make a few cuts in the core on the top. That way the core will crush at the top. You can also save your empty cores, split them and slide them inside the core. Shop around and find the tightest wound roll you can find such as Scott 1000 sheet. I use Scott Kimberly Clark 2 ply. I have a lot of filters and buy it by the case from Office Depot. Don't cut corners on TP quality. Some Scott 1000 sheet has 1 1/2" core.

Ralph,
What would be the purpose of this?

I don't worry about it but some like for the TP core to fit tightly on the center tube. The core size isn't always the same. The important seal in a Motor Guard is at the bottom half of the MG-30 and the top half of the MG-60. The core normally won't crush at the sealing end unless the TP core is much too large. It is ideal for the TP core to suck up against the filter core and seal at the aluminum seal and 2" up into the core. TP filters back in the 60s were designed to take the common 1 1/2" core TP. Now days the filters have to deal with mostly 1 5/8", 1 1/2" and some in between and that can change.
Motor Gaurd Sells There caps To Amsoil, Just a Heads Up ! Rumor Has It That Motor Guard Will Stop Selling There Caps To
Amsoil !
