OK, new to the forum need some advice.
2006 S Type R 82K miles Stock
had a coolant leak yesterday, coolant reservoir had a broken nipple. I was able to reinstall the hose on the shortened nipple, and refilled the coolant.
On the way in to work this morning realized I had air trapped in the system, heater would not work. Got almost to work and the car started clattering and power was diminished. Took a look under the hood and the hose had come loose.
At lunch, went out and reattached the hose, added coolant and turned heat on and got circulation but now have a Restricted Performance error. Car will barely run.
Headed home this evening, stopped and had codes scanned, misfire cyl 1, cyl 2, cyl 3...All 8 cylinders showed misfire.

what has happened to my StypeR?
Help please?

 

Sounds like you over heated the engine and destroyed it.

Take it to a dealer to get an estimate of the damage.

Perhaps, but it didn't show to be too hot (I know temp gage may not have been reading correctly if fluid was low) but it never smelled like it got very hot.
Will the car go into restricted performance mode as a protection mode?

 

No, especially as in the sort of situation you described it likely won't know it's too hot.

If you're lucky, coolant has sprayed somewhere and causing this but it sounds like the engine may well be seriously damaged.

 

Never trust a coolant expansion tank that has failed in any way. The plastic is incredibly cheap and fragile. Always replace the failed tank with a new one so you do not put your entire engine at risk....

 

If you had a air bubble it might have been around your temperature sensor. So the gauge would not show how hot the engine actually got.

We have seen this before.

Good question about high temperatures shutting the engine down. I know the Lincoln LS has a fail safe cooling system which is suppose to act just as you say. It's pretty neat because it shuts down alternating cylinders off and on so the combustion heat is spread all over the engine.

But you can imagine that does not give you a car that drive's very well! But it's only intended to get the car home anyway.

Does the Jaguar S Type have a fail safe cooling system? I have never read that it does.

I read that the 3.0 with CHT sensors can take evasive action but the STR doesn't have them so can't.

 

OK been working alot since this happened so just now getting back to this problem.
I borrowed an OBD scan tool and will see if there is anything else I can find. Mechanic friend told me that there were some jag engines that had very sensitive cylinder linings.
IF I did kill it, (been driving for 40 years and have never done this, quite embarrassing actually). Is an engine swap a good (less expensive than a rebuild) solution? I have just seen engines (complete) for around $4K. I will surely have it checked to see what the damage is but what is typical failure mode in this overheat situation? Cylinder wall damage?
Any help and suggestions are greatly appreciated. I suppose i will have to sell the motorcycle to pay for this dumb a$$ mistake. What makes it even more embarrassing is that I got a new coolant tank but just hadnt installed it yet.
Have had trouble with multiple plastic parts on this car (air cleaner box..)
Thanks in advance for your feedback.

 

The nikasil issue did not affect your year of production.

Do a compression test to see if there's head/cylinder damage.

 

Let us know what you find because we are guessing at this point. Maybe some basics? Is the oil level OK? Any water in it? Pull some plugs and take a look? Can you look in the cylinders?

Like Mikey said what is the compression?

We are just Shade tree mechanics and don't have the car to look at.

As far as engines I would look for a used one. Not too many people rebuild this V-8 and parts are difficult to get. I have heard Jasper was offering rebuilt short/long blocks.

There are usually several STR engines on EBay too. Here is one with 64K miles for about $2000.

Found this on Sunday 9-27. Have to check if a 2004 engine is compatible. I would think it is.

The interchange for a direct fit 4.2 engine is S type r and xf from 06 to 09 but before you get too far ahead of yourself you need to dry out your coils that have most likely been drenched by your coolant leak and yes I want you to pull them all out and blow the spark plugs dry too then clear codes and warm the engine up while keeping an eye on it.

 

I will have a compression gage tomorrow and will check compression. Oil is OK, have a knock/clatter seems to be in top of the engine and not down low. Found a shop that will check it Forza Tuning in Greenville Indiana. They indicate that they have equipment that will alllow them to diagnose.
I pulled one plug, didnt see any moisture on the coil, couldnt see into the cylinder.
I did see some engines on ebay, figure that could be best bet. Truly disappointing to have this happen. I will get back to the post when i know more.

 

I wonder if anyone ever looked into putting a Ford Coyote engine or and older 4.2 litre Mustang GT engine in an STR

 

Yes. Do some searches.

It's a non-starter.

Lots of additional bad things can happen in this situation, but dropped valve seats from the aluminum head is common.

+1 on replacing with a good used engine as the economical choice once the problem is confirmed as overheating damage.

 

Sorry I posted the wrong engine!
You need the STR engine that has VVT. So 2006-2008 STR only. I don't know about the XF but it should work.
