loss of exhaust manifold area, only cold morning, suggestions, sorry lenguage

 

xkr 2001 , 17.000 milles ,


morning to start the car, listening to a loss in the exhaust manifold gasket. is eliminated by driving time is normal, the engine is something ....

 

sound can be heard below the throttle body, and feels a little smell of burning gas, my question is whether it is normal ..
sorry for the post, I try to understand

 

tanngo, are you saying that you are hearing a 'blowing' type of noise rear of the throttle body, maybe under it? A slight air noise is normal on mine, maybe even more pronounced on an XKR with the SC, I am not sure.

Now, a smell of exhaust, that is a different matter altogether. I've not heard of any exhaust manifold leaks with that range of 4.0L engines. If you're sitting still, engine running, you may be smelling the exhaust that is surrounding the car, it will be heavier than air until it becomes dispersed in time.

If the exhaust is leaking at the manifold, I am pretty sure the 02 sensor data would trigger some kind of fault, a check engine light, and perhaps the engine would not run smooth.

I am not totally confident in my statement, so If anyone else can chime in, that'd be great.

 

HELLO, THANK YOU. LISTEN IN THE CAR IN COLD ,NOISE SEEMS VALVES.... BUTTERFLY BODY ZONE COMES, exhaust manifold.
HOT GO AWAY, NO WARNING LIGHT.

 

Because I started my research, Began to hear a noise like valves, Which Are deleted after 10 minutes of driving.

A LOW SPEED IS NOT LISTENING.

 

noise-like rattling at cold startup could be indication of timing chain tensioner problem. I'd inspect them if you haven't already done so, just for peace of mind. Or it could just be circulating oil before the valves are fully lubricated?

 

zone is exhaust manifold, throttle body, I think it exhaust gasket ....

 

hose in my ears, walking area and feel leaking exhaust pipe exiting exhaust manifold throttle body area

 

well, if you can feel the exhaust gases, that's not good.

 

thanks h20boy. There is a pipe coming out of the exhaust manifold, where it is headed and what it does ... I think the loss
my jaguar xkr only 17.OOO MILLES .

 

I found ... This cracked the EGR valve pipe from exhaust manifold.
someone can help me remove the pipe ....please

 

That should be an easy replacement, but unfortunately, I haven't had to do mine or seen how to take one out. Do you have the jaguar technician information system CD? if not, it might have the procedure step-by-step.

 

It sounds like the EGR pipe is leaking.

 

Hi, I have the egr tube cracked, I will proceed to repair

 

 

perfecto , thanks , gracias , ....exelente .

 

was what I needed excellent -....
