vw touran turbo pipe coming off

bomber2

since having a clutch and flywheel fitted i have a steering torque censor problem(previos thread) and now the turbo pipe at the front of the engine has blown off for the 3rd time in 2 days after the 2nd time the mechanic put some kind of sealer on it and guanateed me it would never come back off he actually said he hoped he was not going to be the one to remove it.is there another problem csausing this.

Sealant won't really stop it coming off.Whats securing it?Its usually a large jubilee clip and if you overtighten them it can damage them making them useless.An easy fix if thats all it is as you just get a new one or a Mikalor type clamp which are much more robust.

update,after getting towed to garage the problem is not the pipe it seems to be a diesel problem,the car has black smoke gushing out and moves about 2 mph mec says fuel filter dirty(done 8k) so not old and possible fuel problem maybe dirty.to be continued

My van does exactly that when the turbo pipe blows off, so I can see why they thought that.
A dirty fuel filter won't lead to overfuelling thought.

Turbo dynamics have a sale on atm with some VAG turbos at good prices, might be worth a look.

turbo's are expensive, would it be cheaper to recon it rather than replace it. how many miles has the car done overall? what type of oil has been used to top up or fill it at services? vags are pretty robust and turbo failure is not high on list of common faults. the ESP seem to be a high problem on these as well as clutches and even a review on honest john mentioned a gearbox shattering when something came loose end exited the box via the box's casing, also on the list is lambda sensors failing, abs pumps failing and the abs computer going down without reason.

AET turbos also have some special offers on vag turbos, not sure which is yours though.

Personally I wouldn't recon a turbo, heard too many stories of them failing prematurely albeit on different cars than this.

most turbo's you buy are recon its the same as if it were a alternator starter motor and stearing rack their stripped back to casings and tested for cracks etc and rebuilt with new parts.

agree a recon can be done in many ways for a turbo, sending it to a guy in a hut and asking him to find out whats wrong and replace the faulty part is false econemy, sending it off to the likes of turbo systems, BTN, AET to be done ensures the whole unit is reconned and tested and warranted.

Yes, but they just wheedle out of the warranty by claiming it was oil starvation or such like.I'm speaking from a modified car POV rather than your average one.
I have contacted both above companies and others regarding part exchanging a standard t28 turbo that needs a new compressor against a larger gt30 and none of them were interested in used turbos, saying they only sold new ones.Of course they will recon yours but just don't expect it to last as long.

The problem with turbos is the high heat they are subjected to-I have an exhaust gas temp gauge and see 600degrees c+ without trying, which cracks the exhaust housing over time so often beter to just get a new one IMO.

For the price of a rebuilt one you can nearly buy new, especially with the Garrett ball bearing cores.
