Hi All! My woes with my bravo continue and I'm now at the point where I started to poke around myself to see if I could see where the problem was. As soon as I took the cover off the engine I saw this:

It looks like one side of the engine has become significantly hotter or is letting hot gases escape whilst it's running. The garage have been able to put about a tenth of a turn on the injector pipe into cylinder 1 - so they told me when I took it in on Wednesday, so this may be old damage.

The backstory to this is that the car would be driving fine and then suddenly I'd lose power and go into limp mode, sometimes when I'm cruising along in 6th at around 70mph on a motorway and have been running for over an hour. When it does this it stops responding to me pressing the accelerator and I as pull over and slow down a message comes up "insufficient eng" and then it cuts out. Key off and then on again and it starts fine with a "check engine" warning. It sometimes, but not always, shows an oil pressure warning too.

When this started I was under guarantee from the garage I bought it from, I'm the second owner, ex fleet vehicle with 44,000 miles on the clock. Garage found the fault codes as p0091 and p0092 which are to do with fuel pressure being too high or too low. We've cleaned the fuel system, replaced the fuel pressure sensor and while this was happening every few days it was a manageable annoyance. Today it happened three times in less than 15 mins.

Any thoughts? It's a serious worry as when it happens on fast roads you're very vulnerable and the garage who are covering my warranty aren't a Fiat specialist so I'd like to go back to the seller with some ideas so I can justify their getting a proper Fiat dealer involved.
 
ive only ever had the insufficient oil pressure warning when ive stalled the car, not sure where the turbo is located on yours (mines a 1.4 16v) but it could be a split boost pipe allowing hot gases to escape?
