Engine and Transmission Tech

James,

As long as the timing cover has the oil pump in it, any oil filter base should fit. We know that the 87 Range Rover 3.5L has the oil pump still in the timing cover and that filter base takes a 3/4” -16 thread filter so the Ford adapter works. Not sure if I am understanding your question so sorry if I am being daft.

James, The older Buick and pre-76 Rover cover had 13/16" threads. The Buick V6 with Metric cover had 18mm threads. 76 and later Rover had 3/4" like the Ford. Think it was mentioned above.

This adapter nipple for pre-87 AMC/Jeep 3/4"-16 to 13/16"-16 would work with the Ford 90 degree adapter on early Buick (pre-metric) and Rover 13/16"-16 oil pump filter base. The Metric one would have to be tapped for 91-11 Jeep 3/4"-16 for straight fitting that size both ends.

Thanks for the responses. I know that the oil filter cover will fit the early front BOP Rover front covers that have an oil pump in the cover. I also know that the 3.9 oil pump cover that positions the filter straight (or almost straight) forward has 3/4 16 threads. I know that the Ford 90 adapter will physically fit on this oil pump cover. What i don't know is if when the 90 degree Ford adapter is is attached and the engine is installed in an MGB, will the the filter on this adapter clear all obstrutions, i.e. pulleys, sway bar, steering rack. lower radiator hose, etc. It is hard to tell from the posted pictures that this may be true in an MGB. It is not clear to me that the pictures are of an MGB, perhaps a Land Rover. Anyway, comments and observations are always welcome. Thanks to everyone.
BTW, I had everything solved on my MGB conversion as everything was factory right down to the overdrive and SU's on the Clawfoot.
But then I decided to go with power steering and the FI and everything is morphing. Now the car still looks very traditional but will have EPAS, AC, FI, T5, etc. Oh well, life is short.

James, Hard to tell if Bryan's pictures are in a MGB. I know he has a very nice MGB race car and that is what he intends. PM him on the fit. EDIT: Mark has the MGB race car, Bryan has a Blown drag car. I was trying to help others with the Buick/Rover motors fit the Ford adapter as the GM one is no longer available. There is a tab sticking out I would cut off to allow it to swivel further. The earlier motors had 13/16" fittings. The Metric V6 has 18mm fittings. The adapter I show and tapping the Metric one enables the 90 degree adapter to work with those. It should work as easily as the GM one.

Jim, Thank you for the information. I have PMd Brian.

To Jim Nichols: Might you know the part no. for the Jeep 13/16 to 3/4 adapter? My web searches come up empty.

James, I don't know the part# but it was on 76-86 AMC Jeep. They used the 13/16" GM style oil filter and block threads were 3/4". You would turn it around for what you want. The later one that is 3/4" both sides is all over the web. They were called oil filter connectors. I'm still looking but you may have to go to a Jeep dealer or find it in a wrecking yard.

Found it on Ebay. This is for straight six but v8 in those years had same part#. Enginequest OFA304 oil filter adapter insert.

Thank you all for the information. On the Metric filter adapter/oil pump cover the nipple is cast or pressed into the aluminum housing which means a retap of that part no matter. So retap it or 3/4 and use the Ford right angle adapter. Or use the right angle adapter that D&D used. I talked to Mark at D&D and he said that the right angle adapter came from a Chevy S10. Not sure of that but a Camaro V6 right angle adapter looks just like the picture Graham posted. Mark seemed to be willing to make some of the swivel adapters again but would need the parts. The Metric base is not the problem, but the right angle adapter is. I am going to investigate using a Gems Rover right angle base from circa 78 if I can find one. It has a 3/4-16 nipple and points the filter forward. Question will be at to whether this clears the sway bar. From some pictures of Jim Stuarts installation it appears that this base (Jim used a late Gems from cover with a crank driven pump, but the base points the same direction) will just clear the sway bar if a short filter is used. I will post my findings as I receive them.

Good news one more oil filter base/pump cover that will fit a variety of timing covers and allow an oil filter to mount without any swivel adapter.

The picture shows a rover 3500 front cover circa 87-88 (perhaps other years. This shows the pump cover I speak of attached to I believe is an early Fuel Injection front cover (GEMS) This same pump cover may be available on other years. I do not know the part no. but I am researching that. They are very scarce and probably somewhat expensive.
Notice that the filter is pointed forward and slanted down. I believe it will clear the sway bar and certainly will clear the steering rack. The filter stub is 3/4-16 and a Standard Unipart GFE148 or equivalent which is a short filter of about 3 inches in diameter and about 3.25 inches in length.
I will post more information when availble.

Part no for the above oil filter/oil pump cover etc4276. This is listed as no longer available at Rimmer Bros and some others. Looks like used is the only option. I can confirm that this fits and clears the steering rack and swaybar with the engine in the standard position and using the v8/rubber bumper cross member. It is a good option, without using the D&D swivel adapter or the Ford Racing right angle adapter, if you can find the part.

James, Thanks!

Here is a pic of the cover with a ruler. I had a spare cover and measured the base + filter dimensions. The oil pump cover has a part number ERC0568 cast in, you need to remove the filter to find it. Like mentioned above, the part number you need is ETC4276. With the filter ( a Rover Mini from circa 1976 to ,mid 90´s) fitted the front bottom corner of the filter is 6 cm down from the block oil pan flange and 15 cm front measured from the block front. Or 2 1/4" and 6" if you dislike metric units.

The cover in the previous post is actually a 4x4 cover, easily identified with the protection plate at the crank seal. Also different waterpump that sits higher than those on passenger cars.





And here is a similar cover fitted on the engine. The car is a Morris, not MG.

Hi all,
I can today confirm that the Ford Swivel Adaptor is still available locally, but the OFA304 shows in the EngineQuest Catalog as having been superceded by pn OFA258 and is now listed on eBay as covering 1981-86. It doesn't list the thread pitches but has some application information. Perhaps someone more versed in these engines can confirm it's actually equivalent and can help me use the Ford adaptor on my '66 iron cover Buick 300. If so that's great news as I can solve this problem with a few mouseclicks rather than scour for used parts for months. Here's the OFA258 eBay link:

David, a lot more info here:

Thanks Jim, that's helpful.
How is the stock nipple held in the filter base? Is it pressed into the casting or threaded? And does the adaptor above thread in its place, or does the base need machining to fit?

The nipple is cast or pressed in. It needs to be cutoff and threaded. I think Paul used 3/4-16" both ends.

Thanks Jim, so in that case the OFA258 adaptor won't work for me as I need it to be 3/4"-16 for the filter and would have to find a 3/4" -16 double nipple if I want to use a 3/4" tap to thread the base, is that right?

I mention a later Jeep nipple in that thread that is 3/4" on both ends.
