smoke for poke?

[Toms306]

Sooty arse has a lot to do with the exhaust imo. Straight through flush with bumper - yes, literally first time after it was washed there'd be soot specs! Cant even drive dry the car or the drying towel got sooty after. Standard system with tip slightly out of bumper - not so much, similar level of smoke, but that extra bit seems to help it avoid the car. Takes a lot longer for a noticeable coal buildup.

Its a pain to clean as well, its kinda sticky after mixing with rain and road grime! So glad I don't have to clean veg of the arse end of an XUD lol.

It should be easy to spot the a boost leak due to the breather oil that sprays everywhere. There's so many on HDi's despite only having one boost pipe lol. Small siilcone from turbo usually leaks. Small silicon to inlet usually leaks. Inlet elbow usually leaks. EGR pipe or blank occasionally leaks. But bare in mind my experience is on high milers that haven't been well looked after. If you genuinely cant find a leak and still have the EGR, its possible that that's stuck open a bit.

The problem with fixing one boost leak is you just push it to the next weak point.

This is about 200 miles of abuse, plenty of coaled cyclists and cut-uppers in that time and it's still clean... I'll try and get a vid through the rear window tomorrow.

Cloth/wire brush and carb cleaner should do it mate. I just got In there with a rag and wiped clean All the black gunk but it's up to you as long as it's clean

How? I just made a mess and ended up spreading oily, EGR shite literally everywhere, all over the garage, tools, patio, door handles, car, etc etc.
