John

I am interested in a pair of your half-moon seals and, if you are still making it/it fits (didn’t notice an update to post 28), one chain tensioner plug. These are for my 1972 Series III E-Type V12 engine.

Please contact me to arrange payment and my shipping address: craigbalzer14735@gmail.com .

I’m going to throw away the ones I bought, buy these and permanently install my GoPro in the engine compartment and watch it on my phone.

Hi,
Yes they are available. I had few customers that fitted them to aj6. I’ll try to find pictures.
Try searching online parts catalogue https://parts.jaguarlandroverclassic.com/
If it has half-moon seals part number: C30431 then they will fit

Hi John,

I was reading the post on the half-moon seals. Are you still making them and selling them?

Thanks

Hi John, recently purchased a '91 XJS V12 and mechanic advised me to replace the valve cover gasket. I’m interested in a set of your aluminum half moon seals. Please let me know how to purchase, can be reached at mattyhilt87@gmail.com, or 480-332-6084.

Thanks,

And if you haven’t done so yet, this would be good time to replace the oil feed banjo bolts at the back of the engine. And the timing chain damper release hole cover at the front of the engine. If I remember correctly John John has machined all these pieces.

If he doesn’t answer here, he also has parts on ebay.

Hi - do you still do the half moon seals, chain tensioner plug, SS oil feed banjo bolts and radiator bleed pipe banjo bolts for the V12 - I have an 86 XJSC I and cleaning up.

Hi, yes I do. Here’s a link to my eBay shop:

Hi, yes I do. Here’s a link:

As @JimD_in_Alabama mentioned, it’s also a good time to R&R the banjo bolts.
The bolts are in the above-provided eBay link

John,
Do you still have the lower temp V12 cooling fan thermal switches? I didn’t see them on your ebay store.
