Greeting from San Diego Y'al!

Recently purchased a 2005 S-type, 3.0L w/sport package and started to sniffed some oil burnt fume from inside the cabin and upon inspection found oil dripping at the corner of valve cover captive nut (note it is above the valve cover gasket level) onto the exhaust manifold and cause the fume to enter the cabin via the air filter; **** poor design and that is my opinion. Further investigation actually after the valve covers gaskets replaced and a few more hair pulling moments only to find the leak actually from the lower sensor located from the back of the air intake manifold. Consulted it with the local European Cars dealer Service Manager and the man cordially answered to "replace the sensor seal" like it is a VERY normal thing to do for this type of vehicle.

In all my breathing days thus far with several different types of vehicle overhauls under my belt and especially cleaning off the gunk from the air intake manifolds I have never seen such an animal. 1st) Never and ever seen oil leaking out of the air intake manifold or ever change the seal on any one of these sensors, point and case 1998 Maxima with a similar configuration with no such problem and do recalled last overhaul at 2008 intake manifold was dirty with carbon but DRY, mind you this was 10 years in service as compared to this newer car with only 6 years in service. 2nd) As first look I thought oil rings on the piston are shot and needed an overhaul but wanted to consult further with the experts before commit my voyage to the unknown as there isn't any service manual offer on any book cases anywhere. Da man said "it is normal," and I heard that but don't believe that so at this crossroaD I summoned your expertise to rise and enlighten us all.

Many thanks in advance and hope to hear from you very soon 'Da Cat' doesn't have any error code and runs normal, except for all electrical connectors became so brittle and most of them broke off the locking tab and that was a lot of times to chase a ghost codes but all cleared and right now no err code running for five trips thus far.

 

Yo mun, yer "S" leaking like a boomba-clot? I've got a ridiculous question: Can the leaking sensor be unscrewed and a new one screwed in its place? One of our moderators, Rick (JoycesJag), has the same vehicle and may be able to shed some light on this situation. Otherwise, stay cool mun.

It sounds like IMT o rings leaking take a look at these threads and make sure you get green ones when you buy them.

Beat me to it Rick!

 

In 1998 the emissions laws didn't require the things that are behind the problem. New laws = new problems. BTW, they've got worse since 2005 so expect further hassles with newer cars.

Very fixable. Quite cheap. It's 6-7yrs old, something minor like this can go wrong.

 

Damn Norri, 3 times this past week or so!

Faster fingers buddy .

 

Hey guys! Quick...two moderators dukeing it out.

 

I believe Norri and I would rather drink it out!

 

BFGross,

Here's the tip two bolts are 5/16, yes that is right part of Ford's legacy I supposed, while most are in metric there are some still in standard and the torque specs is about 88in lbs.

 

Are we talking about the 2-8mm bolts that hold the IMT (tuning valves) in?

And are they leaking as the suggestions stated?

 

Thanks you very much Norri and Sunny SC!

Hindsight, I should have titled this thread differently, but my biggest concern here is why should there be that much of oil inside the intake. Or is this part of normacy of a Ford Jaguar? Yes, two IMT sensors with the same part number and have FORD stamped on them.

Replacing the seals were not much of a deal so I ran a tiny bead of sealant and the leak is fixed and still am wondering at some point in time I might need a bucket bridgate to scoop out the oil.

If you guys say that is normal then I will believe you but probably button up everything and give this neutered cat to the pound. Much obliged!

 

I have used 8mm and it slipped so for ***** and gigglo I fitted with 5/16 and voila! I have helped my neighbor with his F150 and according to his research that Ford's effort to switch to 70% metric and remain 30% standardized nuts and bolts it is needless as this piece of info.

 

I had a complete set of Whitworth spanners (wrenches) for working on the old English cars that you would have enjoyed using on your Ford truck. Fortunately I sold them along with some other antiques over twenty years ago! Just like SAE sizes and most things the English do, they made no sense to me!

The English moved to metric many years ago. Not sure Ford (American), owners of Jaguar did

We still use mpg, mph, and so on. It's a muddle.

The Ford parts bin was both good & bad for Jaguar cars. They got a lot more reliable.

 

I just did my imt oil seals and found the only tricky bit was getting the wiper arms off to get the plastic panel off for access. In the end I put a heavy open ended spanner behind the arm to pull the arm outwards and tapped the spindle in with a small hammer. After a few blows it came loose. In the UK most s-types are diesel so they needed the part no to identify what I wanted.

 

And let us not forget about still driving on the left...

 

I've never understood why people adopted the other side, since I believe horse-drawn carts etc all were on the left. And that's back to the Romans and earlier. I know Napoleon didn't like doing as we did, but then France didn't invent the internal combustion engine.

 

Well, the English always want to do things differently from everyone else! It had nothing to do with being like the English. Napoleon wanted to make it more difficult for travelers approaching each other on the road to engage in sword fighting, and as most people are right handed, having them pass each other with the closest arm being on the left was one way to reduce this type of activity by making it more difficult to fight across one's body.

True, the IC engine was not invented in France, but France was the birthplace of the gasoline (petrol) engine.

 

You missed the point. We didn't do things differently. We kept on the same side that had been in use for at least 2000 years. And still do.

BTW, I forgot Napoleon has a reputation as a pacifist. Presumably only in the USA or something?
