the pipe from the intercooler to the turbo, i got my old one of cracked, so replacing it and i cant for love nor money with out breaking it get the bugger back on first time i ever touch my engine so might sound dense, please someone help ideas??? if there is another way??

 

Are you fitting another plastic one or a Samco (or similar) silicone replacement?

If the former, warm the mouth of the pipe prior to refitting, use something like a hot air gun or a hairdryer.

If you're fitting a silicone hose, degrease both the inside of the pipe and the turbo outlet, then spray hair lacquer inside the pipe before quickly refitting.

 

does the jubilee clip go around it also just onto the plastic pipe??

 

Eh? The jubilee clip goes round the Y-pipe and secures it to the turbo spigot.

 

i put it all back together and it doesnt solve my problem. i still have no boost. when is start the engine i get my usual negative boost - green part of dial. when i press the accelerater it goes to 0 and stays there not picking up, what the hell is wrong i got now cel and no other lights any ideas??

although i did unplug the maf sensor it stalled checked the dash and there was two lights on cel and the one next to it which looks like a pipe going into a tank with heat vapour coming of it???

 

I thought you said it wouldn't go past 0.5 bar in a previous post?
0.5 bar is the safe mode for the ECU. The symbol you get on the dash is for an overheated CAT.
If you can't get past 0 bar then the turbo isn't compressing or you have a major (total) leak between turbo to engine.

If you're saying that there was no jubilee clip on there as well as there being a crack in the pipe, hell yes. The boost will be coming out of the broken pipe rather than going through the engine, while the ECU will be fuelling according to the air it's metered on the way in. Cue loads of coughing and spluttering...

I'm not remotely surprised. Don't unplug the MAF sensor when the engine is running, there's a chance that you'll screw your ECU up. As stated above, this "test" won't help you determine a broken MAF sensor from a good one, I don't know where you got that idea.

I know you're new to all this, but, frankly, you've wasted all our time with this one by failing to give us the correct information. If you'd told us about the broken pipe (and, by the sound of things, missing clip) at the start, we'd have been able to give you much more specific help.

Sort your broken Y-pipe out and make sure all three branches are firmly jubilee clipped on before you post again.

 

i only found out the pipe was cracked when subaru said they didnt know what was wrong with the car and then i decided to try and look myself.
i had no idea it was missing til then did i or the crack in the pipe, as i didnt look into the engine, knowing s**t all about them.

and i got the idea from another post i read somewhere, where i cant remember.

sorry to waste peoples time!!

 

You are unlikely to get positive boost without driving the car.. revving it will do nothing but bad for the engine and with no load on the engine it doesn't produce boost.

i did drive it subaru and back, took it there today and left it there. it is now only firing on 3 cylinders.

they said the coil is fecked, would this cause that??

what damage can happen driving it on three cylinders, again sorry if wasting peoples time but i dont know anything about these!!
