Hey everyone,

I noticed some small amounts of oil on the floor today.
I put her on a ramp and noticed oil dripping from the dipstick area.

Cleaned the area, drove abit and made these pictures.
On the pictures you can clearly see that oil is dripping from the designated area.
I read something about clogged crankcase ventilation, some early models have a breather hose attached to the dipstick, mine has not.

Can anyone advice me how to approach this problem?
What do I do with this?

I really want to change the oil soon, but i can not do that with this issue.

The rubber sleeve at the bottom of the dipstick is available for pennies from Jaguar.

However, I would check carefully if that is actually where the leak is. A more likely source is near the the cooler bypass O rings near the filter. Just above and to the left of the dip stick. This is a common failure point and allows oil to pool on the sump flange and may be just dripping near the dip stick.

There is a good write up of changing the O rings somewhere on here. I think it was by alholbro1.


Found it!

That is some really nice information. Thanks for that! (also aholbro, always nice write ups!)
I ordered 4 new O-rings, I will try to do this job next week with the oil change job and let you know the aftermath ;-)

 

Today i had the chance to put the car on a bridge and had a much better peek where the oil is coming from.

I found the source to be the old style sender unit. I can get the new sender unit for a fair price, but the price for the new cable is giving me headache.

Does anyone have some good advice where to get these parts for a fair price? Or maybe another solution?
Part numbers : LNA5642ca , LMD3325BA



Also I found a piece of this seal laying on top of the marked spot on the photo




Is there a seal between the block and the sender unit?
In my JEPC its not clear its number: C22964

 

It surely looks like this ring from Aholbro's post.

Oil leak left side of engine

 

I believe the only seal is the brass washer shown in my picture you referenced.....but that was a Loooongg time ago....

Possibly a chunk of oil-filter-gasket?

If you are talking about the wiring-jumper of the oil pressure "fix kit" it is just an in-line resistor - you could probably fabricate your own fairly cheaply - I don't recall the resistance value but an extensive search will likely reveal it. Not absolutely certain you need it. My gauge runs just proud of the middle mark without inst panel reprogram, but with resistor fitted. Likely, without the resistor it would run elswhere....but if anywhere other than the high or low peg, you'd be fine.

 

I mean the black rubber seal in the sender unit, not the brass one on top.

I found a good old style sender unit for a bargain, I will try this one first.
Looking at your post its an easy job, except for the broken wrench part.

Can I re-use the brass washer?

 

try this: https://britishparts.co.uk/products/...ssure-JLM20791

 

Excellent prices! When the newly bought "old unit" doesnt hold or leaks, ill try that option. Thanks alot for showing me that link.

 

I received the new style sensor with part number LNA5642CA.
The parts guy took it from an engine and he told me there were no additional cables connected to it.

I found the data for the resistor in the cable, so I will probably make my own.
"The resistor in the link lead P/N LMD3325BA is 150 Ohms, 5% tolerance, one watt. Color bands for that resistance are Brown/Green/Brown and Gold tolerance band."

However, do I really need this cable since the part guy told me there were no extra cables from the engine he took it from. He even walked back to the engine to check it again.

Also i really want to know about this tsb I found, about updating the instrument pack.
Can someone tell me if this is necesary when im going to perform this fix?

 

If you update the IP, you cannot go back to the old-style pressure transducer.
I fit the fix kit linked above and referenced in the TSB, used the resistor, but did not update the IP. Oil pressure when running puts the needle just high of the mid-mark.

 

Allright! Then I'll try with a cable + resistor.
So what happens when I don't fit that cable? False readings?

For next tuesday :

1x Oil filter EBC9658
1x Washer for carter EBC9044
4x Rings for the oil bypass CAC5118
1x Oil sensor LNA5642CA with washer
1x Cable with resistor LMD3325BA

 

Self fabricated cable with resistor. LMD3325BA
Looks good and ready to go in!

 

So, the new sensor with selfmade cable is doing excellent work.
The engine is running nice and smooth with fresh new oil.

I cleaned up everything and no more oil leaks!

Excellent job done, I'm very happy with the result.
Thanks for the information about the fix kit!
