Mk3 Ibiza Cupra Blown Engine Advice - With Pictures

[Damo-R]

is going back into your ibiza ??? same as before or a higher output version..??

[wazo]

well its not an AQX engine for sure there like rocking horse $h!t

[wazo]

had the prognosis on the engine now and the most likely cause of the engine blowing is the oil pipe which comes from the backside of the sump (the flexy metal pipe) had a kink in it not sure how this has happened probably been hit with something at some time but the pipe was 1/4 the size it should of been i was told that this pipe is the return oilpipe not the main oil feed pipe to the turbo when i get the chance ill post up a pic of it
cheers
nick

so get checking those pipes

[Damo-R]

whats the news so far wens the return date ...what are you doing to the engne b4 you put it back into the motor ..???

[badger5]

got a mk4 golf in at the mo for IHI conversion..
looks like it has previously been smacked on the sump (weld repaired) and its turbo return drain pipe is kinked/dented.

[wazo]

i have the pipe now off the car i will put up a pic asap of the pipe on question
looks like this was the probable cause of the engine failure

[wazo]

this is what we thought was the most likely problem of my engine blowing up the oil return pipe from the back of the sump looks like it had taken a hit from something at some point

[Old Webmaster]

Blimey thats not good at all Nick ...

[wazo]

it doesnt look good mate
im told that these type of braided hoses shouldnt kink or break at all, but this doesnt seem to be the case now does it, so dont take these pipes for granted people get checking those hoses

[PaPaSmurf]

if only i had a turbo ........ lol

Blimey.. is that about where it lines up with the driveshaft.. and rear engine mount bolt head.. Mines very close these.. extreme suspension travel, lowered car, worn wishbone bushes can allow more movement..
maybe check ya wishbone bushes for wear too in case its possible to happen again.

[wazo]

ok mate i will thanks for the advice tho

So... The initial prognosis about a 'common defect' in the engine is actually an incorrect statement and the root cause is a case of accidental damage to an ancillary part and not to do with the engine or turbo.

Just thought I would clear that up.

If I had a pound for all the times I've heard people say "It's a common problem" I wouldn't be at work today. It is often stated purely because some mechanics often use the term when they don't have a genuine 'root cause'. It appeases (and concerns) some customers and redirects the focus of the failure to the manufacturer rather than the mechanic themselves.

The moral of this 'story' is to check (or get someone to check) the condition of your pipework under the car, making sure it isn't dented, bent or kinked.
An unfortunate situation for you Wazo and I'll certainly be getting the mechanic to check my pipework on Tuesday when the car is in for servicing.
I hope you get the issue resolved swiftly.

Scoobster - From wazo's original description is does relate to a 'common problem'

The long (apparently) service interval on the 1.8t and high oil temps from the turbo casue carbon deposits to form in the oil. These then get sucked up into the strainer causing a reduced oil flow into the pump and around the engine.

In the US, Seat offer an unlimited milage warranty in the event of an engine failure cause by oil starvation after a blocked pick-up pipe.

I suffered the same problem last week. I cleaned everything out and flushed all the dirty oil from the engine. It now starts fine, but i get a nasty knocking over about 2000 rpm. Either big end bearings or hydraulic tappets. It goes into Seat on wednesday to get looked at but I dont think it's going to be cheap!

Any Turbo charged car should have regular oil changes (with a quality oil) and be allowed 10mins(ish) to warm up before any, how can I put it, spirited driving. And also after heavy driving either be driven off boost or left to idle for a few minutes to allow the oil to be drained or whatever from the turbo & linking pipework. Failure to do this will allow the oil to bake itself to the inside of the hot pipework and will eventually restrict flow etc. This is what has caused the failure here.

Even though the car has done only 30,000miles it makes no difference as the way it has been treated is key.
My friend has a Ibiza Cupra currently sitting at 112,000miles and has had no problems due to following the above practise.
