True, squirrels are incredibly mischievous and seem to be getting ever fatter in britain (don't get me started on the pigeons).

Unless I call in the forensic examiners i'd settle on scuff marks from teeth, or filing - swaying towards the latter as the Jaguar was previously owned by quite a well-known english actor, then a wealthy doctor.

Thanks again Steve, new part is on the way. We're considering digging deeper and removing manifold - being the victim of either a bent mechanic, or a lone squirrel begs the question - what else has been partially digested?

 

You're welcome. You will do well to dig a little deeper while you are at it. Especially check the two breather elbows circled in the attached illustration.

Good luck!

 

Great stuff Steve,

Well I noticed earlier this week - the upper hose elbow in diagram is completely collapsed, under a vacuum. Would this signify problems with the lower hose?

 

If collapsed needs replacing. Will cause running problems otherwise. Common fault...

 

Yep! The lower one is likely in the same state. If you go down there, change 'em out anyway. You won't regret it.

Cheers,

 

OK Guys,

Got the manifold off, and loosened plenum to investigate lower-elbow which feels warped but not cracked.

How do I safely d/c fuel line to life plenum clear of lower-elbow area? Where does it d/c, we see the bleed valve.

Thanks

 

I just moved everything around with caution to have access to the elbow.

 

Hi Gus,

Well there really is very little space, and following steps from this thread...mentions d/c fuel-line, barely get me hand down there.

(He is also tech-registered on this forum)

I wonder if the US model is providing you more space?

Regards,

 

I am unable to say your engine setup is different than mine but when I did mine I was able to access the hose and get photos of it in place. I know at this it is a little awkward but moving the fuel rail without removing fuel lines worked for me.

 

Me to Gus, but then again I must not know what I am typing about.

I know the picture below is from a MY 2003 (US) but there was plenty of room to gain access to where the elbow in question is located.

 

Gus,

I took note of what you said and played around with plastic spaghetti...sure enough i got the plenum clear without d/c fuel-line. My worry was knocking the infamous hose nipple which is currently wrapped in cotton wool...


Thanks Rick, exactly how mine is, those inlets could do with a polish.

Before I attempt to fit new elbow I came across this diagram which shows both breather hoses attached via a bracket...see single nut hole on back.

Has anyone attempted to loosen this bracket to help fit new elbow?

Regards,

 

For what it's worth, when I change that lower elbow, I carefully cut it so it can be removed from the nipple and the pipe. Then I lubricate the new elbow and pinch it together into the space between the pipes, I can then massage it on to the pipes as it opens up. That way I don't have to worry about the hard to get at bolt for the bracket. The new elbow is pliable enough to get it on that way.

I'm not necessarily telling you to do that, but that's what I do.

Good luck!

 

Put a very small amount of grease on either end and hose slipped on very easily.
I figured putting new hose on connection closest to firewall initially gives us more space to finish other connection. 2 minutes tops.

I wiped the throttle-body clean with some WD40 - looks like something has eaten away at the special coating in places. Will this need replacing eventually?

 

Maybe, but maybe not in the life of the car. I suppose it'll depend on whether the PCM can successfully control fuelling well enough to avoid such as cylinder & cat conv damage. And keep emissions OK for MoT.

I wouldn't rush to replace it...

 

The weekend is here so it's time to rebuild.

The question is...intake gaskets reuse or replace?
Comparing my originals with the new genuine the lower gaskets have definitely warped slightly over 12 years but upper gaskets appear sound.

blue rubber material - is this a special sealant coating?

 

I would replace all the gaskets. It is a small price to pay to get the job done correctly.

As you mentioned Leonard, 12 year old vehicle.

 

Thanks for the advice guys,

Everything going back together nicely...

Quickly checked spark plugs - they're an absolute mess showing erosion and 2 - 2.3 mm gaps.

They're Motorcraft Platinums FS22 's - RH Bank plugs have "07" engraved on the shank, LH Bank have "09" - very poor condition for newish plugs - can you recommend replacements?

I see Motorcrafts are very cheap from States.

Thanks,

 

I'd use the kind suitable for the engine as they last at least 70K miles (my engine type uses iridium and they're 100K).

 

I installed Bosch plus 2 in my 2000 S-Type 3.0 and have not had any problems at all.
