    Default Cleaning Turbo

    How do you clean the turbo?

    My car seems to be lacking power and i heard that cleaning the turbo and boost hoses can make a difference.

    Is that a load of sh*te or can it be done?

    Removing the pipes, and cleaning any large accumulations of crud out will probably be a good idea, before it comes unstuck and either gets blown into the engine, after cooler or sucked into the turbine.

    As to power increases, only if the pipes are very restricted would you notice anything huge.

    Cleaning the turbo shouldn't really be necessary. BUT, if you feel you must do it, a lint free cloth with a dab of petrol would be OK to wipe around the parts. DO NOT dismantle your turbo.

    Cleaning the turbo?!! The only way it would make a difference is if say the turbo was a variable vane type and the vanes had got coked up and were sticking in the open position, therefore giving greatly reduced boost. Giving the turbo a clean up/de-coke would resolve that.

    Unless you're confident in that area, you wouldn't want to be taking a turbo out on a whim, and you certainly don't want to be poking around the impeller area if you don't know what you're doing.

    Thought it sounded a load of sh*te. I put a fuel cleaner in the tank last month and noticed a slight difference but the car feels very sluggish

    Thoroughly check the boost hoses then, make sure they aren't split or perishing, or loose even.

    Sorry guys.. gotta ask..

    now we all know that you should not dismantle your turbo unit unless you have the correct rebalancing equipment ( very highly unlikely).. so , given that the impellers run so close to the casings ( to generate pressure they need to run tight) how do you propose that TAM pushing a petrol'd rag into the turbo to 'clean' it is A) a good idea as pieces could come off into the turbo.. b) the petrol will have a degenerative effect on the oil seals on the turbine shaft c) if you loosen any carbon how do you propose to make sure it's come out?..

    Tam, a turbo isn't a cleanable or serviceable unit unless it's in the hands of trained professionals.. DO NOT attempt anything on a DIY basis..any minor carbonising of the exhaust impeller chanber is fine, and you will find little to clean on the air compressor wheel housing side...99.9% of whats in there is just air with very very minor amounts of oil mist on the pipes walls...

    Hey, I wasn't suggesting Tam went anywhere near his impellers (unlike Ste! )

    When I said "...and you certainly don't want to be poking around the impeller area if you don't know what you're doing."...I maybe wasn't clear enough. What I meant by that was he doesn't want to be poking around the impeller area if he doesn't know what he's doing i.e. the people who do are the turbo specialists who would take the turbo apart to properly decoke it.
