I have a major leak on an air pipe & just wondering if anyone knows which pipes usually break or split?

I've taken intercoolers out & checked pipes too & from engine but they're OK. Could be a pipe going from turbo to filter box though but I can't get to the bugger!

I was overtaken by a Rover metro today, wasn't impressed with me Z at all!!!!

You mean which pipes ?

 

If you are drastically underpowered then chances are it could be the Wastegate pipe - It goes to the Actuator of each turbo from the underneath the inlet hard pipe to the IC ( the big black one next to the Throttle body hardpipe )

 

Check the Hose clamps at either end for splits or faults. Failing that give them a dusting with talk or summiunt and generate a bit of boost with the hand break on while gettin someone to watch for white showers !

 

These lines are quiet long and partly hidden so it wont be a walk in the park - failing that it could be the BCSV lines which are very small and can get brittle - they are T sectioned off from the above mention lines a short way after the actuator on each turbo.

 

Best of luck

That reminds me to ask something I've always wondered about.

Why is boost only produced under load and not when the engine is just free revving?

Never got my head round that one for some reason and I'm prepared to look like an arse for asking!

 

I swear, I never hit post twice..

Because - put simply - the engine needs to ingest less air/fuel mix to reach a certain RPM when there is no load on the engine (because it's not working *against* anything)..

 

The less air & fuel it ingests, the less exhaust it produces to spin the turbine blades in the turbo..

 

Simplification, but you get the drift?

 

Shaun - there are hoses from the plastic turbo inlet pipes to the crankcase, are these split?

There's also the whole whole air bypass valve system on the passenger side - if any of these hoses are split, it would be quite a big leak..
