I purchased some 10k Boost from Halfords yesterday. Instructions say to spray directly in to air intake after MAF sensor. Spray for 1 minute with engine at 2500rpm then let idle for 10 mins.

I sprayed for 1 min. Took my thumb off the cap and the cap came off and flew into the air intake!!! :(

The turbo did sound like it was spining up louder than normal between the time it took me to turn the engine off.

I can't find the cap, but there are tiny bits of white plastic swarf in the pipe that goes from the intercooler to the EGR.

So, what the hell have I done? Will I have killed my turbo and will bits of plastic inside the engine in turn kill it? What do I need to do now?

Other than commit suicide as I haven't even finished paying for the car yet! :(

Help. Please...

tnx

Nik
 
Most of the debris SHOULD be trapped int he intercooler rather than having got to the engine. The turbo is the worry, you need to get the air intake pipe off to it so you can see the vanes on the compressor side and carefully inspect them for damage. If they are damaged then turbo is ostensibly scrap. Intercooler needs removing and blowing out with compressed air to try and shift the swarf. Minute bits of plastic are unlikely to harm anything in the engine.
 
Jeez .. I'd strip the intake system down to the head and just try to clean it as best I could .. and maybe pray!
 
dont know about rangies , but if it were my disco i would clean out all i could find then give it some stick to blow it through (get it bit hot to melt any plastic bits off) . shouldnt think it will do any damage,but thats just my opinion

It's not the engine that is the problem, a bit of plastic in there would be atomised PDQ it's the turbo that maybe the problem. Let's hope not.
 
I'd also be composing a rather snotty email to the customer services department of the manufacturers of the product about the quality of their spraycans and who is going to pay for the damage.
 
Agree with the above - engine will burn it out fine....but the intercooler could be blocked....strip the iinduction system and clean like crazy....

Turbos while fairly delicate can withstand a bit of abuse....take it out and check the impeller for dinks.....doubt it would do anything to the oil delivery to the turbo bearings, but check the impeller blades for damage, they can be carefully filed to remove dinks, but depending on how bad the dinks are, you could take it out of balance....
 
Is it a DIY job? I've looked in RAVE and removing the turbo sounds simple, but I can't even see it. Not sure if you get it from above or below and no idea how to get the intercooler off...

I'm glad about the bits of plastic in the engine at least. Just the turbo.

Halfords are considering footing the bill but I have to get it sorted first. Any mobile mechanics in Wigan that could come out and sort it this weekend otherwise I'm stuck till monday. or do it myself if I can...

Given the speed at which the turbo spins I would have thought removing any material from the vanes would put it out of balance and lead to expensive self destruction. Remember we are not all aero engine designers Ant:)

I was watching a video about how they build turbos a few years ago, they balance the turbo by grinding off very slight amounts of material. The smallest amount is the difference between failure or not.

How a turbocharger is made - YouTube

About 4 minutes in they get to balancing. You can see how little material is removed. I imagine if the plastic cap has taken off any material or left residue it will be enough to throw things off.
 
****ing ring Halfords up tell them they have to fix it, there was no warning on the tin that the cap would come flying off, at least rip in to the bastards, and ask them for some ££££ everyone else duz now days

Granted - I did say carefully!!

Maybe I should have said if the dinks are minute, they can be carefully filed so as to remove as little material as possible to not ruin the balance of the impeller disc...

Centrifugal Gas Turbines are old hat, I work with Axial Flow - so any blade imbalance is easier to correct....
 
Found the offending bit in the turbo intake pipe. See pic. It has clearly met with the turbo blades! I couldn't get the turbo out (just couldn't suss it). But I did feel each blade with my fingers and they all felt fine with no dings or rough edges.

Intercooler has been off and cleaned and all hoses so all bits have been removed.

Put it all back together but not started it yet.

So, the only questions is: Do I run it, or do I take it to a specialist and get the turbo checked/replaced?

should have got a mirror and had a look inside the turbo. they may all feel the same but could be burred over.
 
Run it, if the turbo sounds OK no unusual whistles or screeches should be OK. If it disintegrates like the one on my Xtrail, the intercooler will collect the bits before they get to the engine.

Does the spray nozzle still work? Try it again and let us know. Run it, it will be fine. :D:D:D
 
Some progress: Halfords have "verbally" agreed to foot the bill. "Get the work done and then claim it back off us" what the way the put it over the phone.

So, would you bother with all the hassle of getting it in to a garage? Insist on a new turbo? Have this one inspected? Or just leave it...

Your advice would be appreciated. What would you do...?
