Hello,

I recently ordered (for my 2000 Jaguar S-Type 4.0L):
-New spark plugs (NGK Iridium with a gap of .050, because I couldn't find a definite decision on which ones we should buy)
-New coils and boots(from DependableAutoparts on eBay)
-Valve cover gasket set(made by Victor Reinz)

I am about to order the timing chain kit for $450 from Welsh Enterprises.

I will not be doing any of the installation myself (sorry!), but I'm wondering if there are any other parts I should get for my mechanic to replace while he's working in that general area (parts that are prone to go bad eventually).

Thanks!

-Chase

 

I recall a write-up on Jag-lovers - the most visited Jaguar enthusiast site on the Planet! but sorry can't recall anything about parts.

I think the guides may be C2A1456

I think these are relevant articles, but am not 100% (you'll be on 3 or 4 gen, metal bodied)

 

The kit comes with the following:

2 - EAZ1269 - Primary timing chain
2 - EAZ1286 - Secondary timing chain
1 - NCA2017AF - RH timing chain tensioner
1 - NCA2017BE - LH timing chain tensioner
2 - NCA1995AF - Timing chain tensioner
2 - NCA1998AB - Timing chain guide
2 - NCA2025AB - Timing chain blade tensioner

Is $450 overpaying for all of that or not? If it's a good price, I'll buy it. Will there be anything else that I should replace?

 

Have you read the two articles JagV8 posted?
They have a wealth of information in them.

Do you have the JTIS? Might be useful to whoever is going to do the repairs as it's a big job.

I don't have the JTIS. I should get that soon. I did glance through the articles. I'll read more thoroughly when I have some time later.

I discussed what I wanted done with my mechanic, and he's down for it. He has been working on Jags for 20 years, so he'll be fine for this job. He did say it's an 8 hour job, so I see that it must be a big one. Does 8 hours seem appropriate to you?

 

Read this thread before doing the job - https://www.jaguarforums.com/forum/s...ld-i-do-35211/

 

I'm not sure how it applies to a 4.0

 

I'd be willing to get the IMT O-Rings, if that's applicable to the 2000 4.0L, but the manifold gaskets are just another expense I can't afford right now. I'll keep them in mind for next summer (Again, if it's applicable for the 4.0).

 

The general idea is the same, isn't it? Upper / lower manifold; imt o-rings, coils, plugs etc. Why do we always split hairs on this forum?? Just giving the OP a place to start. If there's a more comprehensive list of components he should replace on the 4.0, I could not find it for him on the forum. Could you?

 

You don't take manifold off for plugs & coils on the 4.0 only the 3.0

No IMT o-rings need changing either.

Don't see how it's splitting hairs when things do not apply.

 

If something in the thread to which I referred the OP did not apply, then by all means you could have said specifically which parts of it did not apply to his specific engine and thereby enlightened both him and me.

To simply say "I'm not sure how it applies to a 4.0", without saying why, sounded like one more case of splitting hairs on this forum, of which I am growing tired.

Meant no disrespect to you, JagV8. I respect your knowledge and really enjoy your posts when they contain some useful info - your advice always seems to be spot on - but it does none of us any good when you post a mild smackdown without citing any reasons why. Had I not prodded you, you might never have posted the above response, which actually includes your reasons why you thought the link I posted might not apply to the OP. I apologize if I offended you. It was not my intention.

I'm simply doing my best to help another forum member out by pointing him at some more info on the forum that might be useful to him.

OP has a 2000 S-type, most likely with considerable mileage on it (he doesn't specify). He's changing timing chain, plugs, coils, boots, valve cover gaskets and was also looking for recommendation of other parts that might be ready or necessary to change "while he's working in that general area (parts that are prone to go bad eventually)."

I pointed him to the only thread on the entire S-type forum I could find that had any useful info on a comprehensive component replacement, albeit on a 3.0L not a 4.0L. I assumed his parts supplier would be able to tell him which components did not apply to his engine. If his car has no IMT O-rings, lucky him. Everything I've read on this forum suggested to me that every S-type had them. Shame on me.

NOTE TO MODS: If there is nothing useful or relevant to the OP's 2000 4.0L S-Type in the thread linked in Post #6, please delete post #6 in its entirety.

 

I wasn't offended, but concerned that anyone with a 4.0 might think the 3.0-specific stuff applies when it doesn't, with much wasted time.
