Been there friend.

The original ford elbow joint that feeds the inlet manifold spilts, it's just a matter of time. It takes a decent pressure of air and though the ford part is reinforced, it does split due (in my opinion) to a weakness in their part. When mine went I phoned ford for a quote to replace the tube and was told £100+ so I quickly checked for a cheaper alternative.

I found a company on a certain online auction website that makes the elbow joint in silicone which can take way more than the pressure deilivered and it was about £7 inc p&p, 20 minute job and the elbow was in.

Anyhow, just giving background info in case others have the same problem.

The turbo will be fine, the lack of pressure won't have done any damage, (unless you were raking the car), the initial blow out won't have done damage either as the split starts small and gets bigger meaning it was probably split and you never knew. Sleep soundly chum.

By the by, I would check out the last issue, sounds like the egr or exhaust manifold was plugged up. When you say all the power went, do you mean the car turned right off? Or was it a slump in revs?
Focus' have a problem with their ecu that makes them completely shut off if they drop under 750 revs for some insane reason. Does that sound right?

God bless

hi phil the pipe you need is at the front right hand side under the EGR valve and goes to a steel pipe at the front bottom of the engine

hope this helps

kind regards Neil
