Just got extreme well kept 2001 S type 4.0 with locked engine. Ex Owners mechanic says low oil. Last change was done by a quick lube service

What is involved to swap in a 3.0 Engine?

 

far too much trouble to make it worth while, stick with the v8

 

Yes I am finding it hard to find a excellent used 4.0. After I get full diagnosis of damage, then tear it down... I might rebuild the present engine myself. Where are best sources for parts?

 

i'm in uk so cant help but i'm sure someone will be along soon that can, the are also quite a few ford and Lincoln parts that are interchangeable so you might be able to save a few $ using those instead of jaguar branded parts.

 

I think you need to understand why you can't find a good 4.0L??

With the age and miles on all 4.0's by now the timing chain tensioners have all worn out and destroyed the engines. Even if you do find one be aware that you have several thousand dollars of repairs and updates to do.

The car is worth nothing at this point and even in perfect condition you will be WAY underwater on the car! Your best bet will be to move on.

If you want an S Type please use the combined wisdom of this list. We have the deepest experience and knowledge anywhere of the S Type.

Get a 2003-2008 S Type.

And yes I have not even started talking about Nikasil!! If you don't know what that is then again you are in over your head! But to be fair by 2001 that was pretty much over.

Opa! You sure are bundle of joy!
Worth nothing?
I recognize the problems, serious aggravations and disasters...but many drive these long way with min problems..I know of two went 175,000 with good care before trans lost...(not the norm) Others terrible, I suppose...and later models much better in many ways...
Lots of worthless early S types out there going every day. How many on this forum drive one?
I could well find out real hard way, but right now seem you are overly strong on spreading despair.
The car has over $600 of new tires on it and much new maintain spent. Lady driver loved the car..but couldn't live with $6800 estimate to fix. MY worst is, I could not get away to tow it and save couple hundred.
I could lose some, but not all.
Main regret is I have too much to do already before I took this job on.
Help I need is find one head and best source for quality gaskets.
I have a extra transmission and a good 4.0 missing one head I got real cheap.
That's all...

As a daily driver of a 2000 S Type with 4.0 engine with over 207,000K miles - hate to say it but clubairth1 is 100% right about his assessment of the 2000 - 2002 S Types - they are indeed worthless...

I personally lucked out as I changed out the tensioners, guides, etc before the common "death rattle" upon start up - not once but twice - most 4.0 V8 S Type owners wouldn't even think of shelling out $$$ ahead of time - only when the tenioner(s) failed wreaking havoc throughout the affected cylinder bank.

I love my car - I do but the only true value it has is currently is to me. I could never sell her for what I have put into her - hence the under water comment (BTW - I have much more than $600 worth of tires, etc in my car) - your new tires and "maintenance" is not going to do you any good with no viable drive train - and I'll be one to state - you DON'T take a Jaguar to Jiffy Lube or a "fly by night" quick lube service. NO ONE changes the oil BUT ME! Oil is super critical for these engines!

Again, if you do find a used 4.0 engine (for $2,200 and up) in order to ensure good operation - those tensioners (at the least) need to be changed - and if you come across a 4.0 with updated tensioners in place - expect to pay $3,500 + for it.

The wrecking yards know these engines are hard to come by in running condition.

Hate to say it but you make some $ by parting the car out as the parts are worth more than the vehicle itself!

PS - clubairth1 is a bundle of joy!

 

Well let me tone it down then???
The MARKET considers the 2000-2002 S Types to be worthless! Heck you can’t hardly sell an STR anymore!

You on the other hand may value it much higher but that will only be true for you.

Be ready and willing to do a lot of repairs. Just look at abonano post. He has replaced the timing chain tensioners twice!! I must say my hat is off to him for that because as far as shade tree mechanics go that is a SOB to do. But he did all that because he loves the car not because it was the most economical thing to do.

Did you ever find a place to buy a rebuild kit?
I'm playing hell trying to find a overhaul kit for the 4.0 engine!
can't seem to find one!

 

I saw a 4.0 about 6 months ago in a yard in Pell City , Alabama. The back end of the car was wrecked. The front was untouched. The engine was fine. No leaks, broken anything, or missing parts. In the mean time this number said they have a 4.0 engine (256) 458-0360 ext. 256 Give it a shot.

 

You might contact Jasper as they are a giant re-builder of engines. BUT I think you are going down a wrong and expensive road?

Think about what you said for a moment? You can't find parts. That is telling you something. What's it's telling you is there is little to NO demand for those parts as no one is rebuilding these engines.

Read the comments above from guys who have over 200K on the 4.0L V-8 and look at what he has been done to keep it running and on the road. It's not a small amount of work.

you can always swap loom and sensors over to a 4.2 and bolt that in , it wouldn't be the first time some one has done it .

 

thanks for the tip, I'll call asap!

 

this is true, but it's a matter of determination for me at this point! Lol, I can get the parts individually... I just wanted to get the whole kit at once... I realize that these engines are basically junk... I may try to find one of the 4.2 engines and try that.... haven't quitedecided yet... love the way that the S-type looks and feels... just wish they hadn't put such shitty engines in them!

 

In what way(s) do you think they are like that?

 

the research I've done shows that the timing chains almost always gives out and screws the engines up... but I like the car.
I bought mine as a project... the feller I bought it from saidthat the engine was locked up... I started tinkering with it and got it running again... but sounds like it has a screeching sound that turns into a knocking sound when the accelerator pedal it pushed down... my friend thinks it just needs a new flex plate... I'm not sure that's the case though.

 

Fooche.

Take a look at your project from a different perspective. 2001 to 2002 S-types with a 4.0 engine in great condition have asking prices of $5K to $7k. (50+ 4.0 S-types are for sale right now on Auto Trader.)

I you can put in a refresh engine and come out under $7K and are happy with the car, then drive it and get your money's worth out of it. But if you can't get the car running for a total investment of below whatever you think the car is worth, then part our your car and purchase one that is running.

 

You're way out on your research. It's just the 4.0 and all that needs doing is replace the parts (tensioners etc) for the more recent parts (available for over 10 years).

Or just buy a 4.2.

 

Why not get in touch with n2audio and buy his wife's car, it has been damaged at the back but you should be able to repair it.
It would probably cost you a lot less money and you would have a 2005 car

Glad to hear it!
Just wanted to let you know it won't be a normal or easy road.
But please post back so others might benefit from your efforts.
