It was only recently that I posted saying I have an XK engine with no oil leaks in reply to another thread.
Well, I rode past the front of my XJ6 this morning on way out to work, only to see a huge oily pool under my car. Tuesday I was hunting down a rattle in the engine bay and didn't notice any leak. The rattle turned out to the top mounting bolt for the trans dipstick tube I had not replaced when I removed the trans pan a couple of weeks ago,easy fix.(wondered why I had a spare nut and bolt)
When I arrived at work there was nothing to do so I've taken a day off to come home and investigate further.I'll post my findings later.

 

Update asap please! Everyone on here has an deep interest in Jag leaks. Oil filter shot?

 

I still have an XK engine that doesn't leak oil,maybe weeps a little around the valve covers. But not enough to have to clean up or wipe away,no runs. Just a film right on gaskets with dust stuck to it.

It turns out that the said oil was only fuel and dissolved bitumen. But sticking a finger in it at 5am when half asleep, it sure did feel like oil between the finger tips. In hindsight I should have known it wasn't oil as mine is clean,not black.
I went into a state of semi panic with losing that amount of oil in 8 hours. Thinking the worst, I was imagining rolling up to the All British Day on my Triumph with my Union Jack helmet instead of the XJ6.
Traced fuel leak back to the front carby overflow, the float needle had stuck open. Removed the needle gave the bore of the seat a hone with 1000 grit wet & dry. All seems good so far, I hung 1/2 litre of fuel above the carby to gravity feed and removed the jet tube to drain and refill the float bowl 5 or 6 times. I split the jet tube(bloody new it was too) so had to go to the mower shop to buy 150mm of mower fuel line ($2.40)as the auto places don't stock one with the right ID an OD for the jet tube. I know this because when I first played with carbys one of my jet tubes broke(brittle) and I stole the fuel line off the lawn mower to get me going.
It has now been for a 25 mile drive and been parked on the same slope for 3 hours without leaking.

Here is a shot of the oil filter,not the original set up. I think some kind of adapter has been fitted,it takes the same spin on filter as the V12 now. list of filters that fit below. If I Had seen your post earlier I would have removed the front carby to get better pics for you. These were the best I could do between the carbys.

Clarke,

If the car was facing forwards up your drive it would have to be a very serious leak to drop anything at the front!

I never found my straight six Series I or Series II engines to be completely oil tight the way the later AJ and current V8's are. In particular, the cam cover seals were carried over from the 1960's design and would leak intermittently.

That oil filter setup looks a lot better than the OE.

The oil filter and twin thermo fan set up is about the only thing the PO got right.(if he actually did fit them). Everything else he said he had done either had stripped threads or was put back wrong.


I gave up trying to park on the drive. Facing uphill it was dropping trans fluid from the converter,facing down the oil pump is too weak and it knocked for a minute or so when I started it so it's the garage or the road now. I really would prefer parking on the drive but a knocking engine isn't worth it.

 

That Z133 filter cost me $45 at repco...

 

Hi Richard, the ryco one is a bit of a rip off.
The HiFi one is from Jagdaim in Melbourne, $15+ postage. You would probably get it delivered to your door for $20 all up.

Any chance your series II is registered now and you making it to the All British Day. Less than 1 hour from you(Caboolture ?)

Good quick fix.

That oil filter "adaptor" is S3 6 cylinder from memory.

Hunt down a Wesfil stockist, and they also have an equivilant Z133.

 

Hello Clark, its a series 3 and its not finished yet[basically needs tyres for rwc], work is very slow[no work tomorrow so will be rubbing it back with 1500grit and buffing]

 

Sorry Richard, I had it in my mind you had a series II for some reason. There always seems to be just one more thing for that roadworthy. you could always come without your car for a look around and meet a few local members,that would make 5 for us.
Have fun buffing, I'm going to work to read the paper for the day. Slow week but I got to be there to get paid.

 

>WHEW!<
Clarke, I am So glad it turned out to me nothing so serious as a massive oil leak!
I can see how that sort of puddle would give you a start!

Clarke, sigh of relief from me, too. Though in a purely selfish sense I'd have enjoyed reading how you dealt with it.
