And most still on the road have been converted to the lower pointing/facing outfit unless concours. There are only 1600 S Types left on the road in the UK or at least registered ~ some not on the road. Every South African built Mk2, S Type & 420 had the downward facing canister ~ We machined the blocks & heads accurately here on new state of the art equipment for the era paid for by the SA tax payers. That's over 2050 Mk2's & 850 S Types & 840 420's. So they sent the crap to the US. Our greatest problem is dust while the UK's major issue is rust. Hence our high survival rate. I wonder what the US survival rate is as a percentage of all cars shipped to them.

So today as rare as rocking horse droppings. We are talking here about Mk2's & S Types & the odd 420 ~ you are talking about ALL engines built & not into which models they are fitted ~ another distortion of the facts being discussed here.

Even Peter [who knows his Mk2's very well] agrees ~ Quote " We might need a definition of 'downward facing.' The type in CF's picture is happily uncommon and certainly requires a drain plug. Without it, opening the canister may lead to a good soaking with oil for an unsuspecting mechanic."

 

Problem is we like to be as factual as we can so that what is stated can be understood and used by others who might not be as knowledgeable.
Giving facts such as "was used on 4673 3.4L engines and 7448 3.8L engines so not so rare" does not really help as there were 24,993 S types made, 83,976 Mk2s made, 37,397 Mk1s Made, 10,009 Mk9s made, 6,227 Mk8s made, 30,969 Mk7s made, 24,282 MkXs, 16,060 420 Jaguars and Daimler Sovereigns, 72,515 E Types made which all used the XK engine and I haven't even looked at the C Type, D Type, XK 120, 140, 150 and all the XJ6 cars that ran the XK engine.
I would say your paltry 12,121 engines with the upward filter is very rare compared to the 306,431 calculated above. Less than 4% actually.
Your entry regarding the drain plug was inaccurate and confusing especially with your inverted diagrahm. It is not up to Admin to correct your mistakes so can I please ask that you correct your inaccurate statement, rotate the PDF to its correct orientation or remove it as it is not helpful. Thank you.

 

My 1957 MK1 2.4 has the dreaded "downward" facing oil filter.
It is a total pain in the rear end as a filter change involves an oil bath for the right-hand side of the motor and lashings of degreaser after the event. I can understand why a concours person would not like doing this
It is also compounded by my fitting SU HD6 carbies to replace the dreaded solex carbies so access is pretty tight.
I have now located an "upward" filter and housing and intend to fit it once this summer's 35C (95F) days start to ease back

 

Cass the J34 is of course the MK2 SPC only. When you bump total production numbers for the 2.4 and 3.4 Saloons with the MK2 and XK150 against the change in filter style you arrive at a significant number at about 75000. Of course as you say there were other models prior to this period and later. The MK VII-IX carried a different style yet and the E type and MK10 and of course the S were different. We were just addressing a question in this forum heading.

 

Thank you for the reply and I totally understand you were trying to address the question raised. It is just unfortunate that the information you gave was not correct or of any help to Schmitty as you were both referring to different filter orientations. If you could edit your previous entry and correct or remove the PDF it would be very helpful. We appreciate the wealth of information you hold regarding our Jaguars but there is also a responsibility to weald the information correctly. Thank you in anticipation.

 

Cass we will try to remove the PDF but at the same time> As far as Schmitty he may wish to declare what Jaguar he has and year. You are correct in the sense the word "downward" can be seen from both directions. As far as the PDF we assumed that most folks here know the page numbers are at the bottom of the SPCs. Why the program here turned it is a mystery but in the 3 attempts we made to load it it did it each time.

 

For future reference. Open with Microsoft Office by right clicking. Rotate file to desired position and save the document under a new name. Then delete old file and re-post under the new name & it will hold it's orientation. Snip page if necessary to achieve.

 

Just for future reference, here it is rotated:
