This is my 2nd rover which is having the same exhaust leak from the same spot. Its coming from the pass. side exhaust manifold. So a few questions:

1. Is it smart for me to try to take it off and get it welded risking that a bolt might snap off and than i am screwed or have a muffler shop do it since they have a torch?

2. Anyone try to take one off and snap the bolt?

3. If I snap the bolt, than I have to take the whole head apart?

I've yet to have a bolt snap off on a Rover head and I've done loads but there's always a 1st.

To remove bolts do it on a cold engine, not even start and move attempt, aluminum and steel do odd things to each other when warm/hot.

So I would remove for repair

If work has been done on the exhaust system in the past shops often don't fit gaskets. On a steel head with a steel exhaust this is usually acceptable, but with the aluminium head there needs to be a tiny amount of give. Make sure you have gaskets in there, if not whip the bots out, slot them in and tighten it back up, its not a massive job, but can be difficult to reach etc.

no problem, the biggest thing im worried about is while im loosening the bolt out, is not to snap the bolt. Our exhaust manifolds are aluminum or are you talking about your 03+ range?

For easier access to the exhaust and heat shields remove the fender wells. You will definately want the extra room for the lower heat shield bolts that are usually rusted in place.

Exhaust manifolds on P38's are definitely stainless. I have never heard of any car having aluminium as an exhaust manifold, they are either cast iron or stainless tubular.

Hi guys, My car has a leak on the R/hand bank (from the driver's seat), and it has gotten louder recently, more noticeable under load than when revved at idle. My questions are,

1. Could it be a gasket or a cracked exhaust?

2. Is the fix a simple DIY or specialist only?

Any help much appreciated.

if it sounds like a tractor, then its probably a head gasket. :(

I had one. Passenger side (Right side of LHD). The hole was in the accordion section of the manifold in an inner crease rather than outer one . I was told by the tech that he sees a lot of these, and that they usually can't weld it up successfully because it's in a flexible spot of tubing. Could have been BS, but made sense to me. I let them buy a new one and put it in during the head gasket job.

There was a recall for cracked exhaust manifolds on P38A Range Rovers. When I bought my 2001 model in 2005, I couldn't register it until I had this recall checked out. There was some record with the DMV. I was told that I had the proper manifolds in place already, and there was no work to be done.

Wow! how can I get tubes like that?

Went out and around London Yesterday, and got on the A12 from the Blackwall tunnel, after pressing the sport button, and opening up a bit, got stuck in a tail back. The noise had gone from a loud ticking to the sound of a low flying helicopter! So, have I blown a gasket or cracked the exhaust and how easy is this to fix.

Thanks for any help.

ps. The noise gets a lot louder under load.
