This is a for a Jaguar Valve cover oil fill cover. There is a tall thread and short thread version. At this time, I only one short and two talls.  If your opening is tapered, then you probably need the tall version. Flat openings use the short.  The script might not be horizontal. This can be worked with by changing the size of the o-ring or gasket.  The are for the larger hole openings of about 2" so will not fit the later XJ6 cars.   These are genuine Jaguar that have been cleaned, bead blasted, polished and threads checked.  I do combine shipping.  Click "Buy it Now" and request shipping amount if buying more than one item from my store and I will send an invoice.  Shipping is for the lower 48 USA.
