The sun was out for a brief spell and the roads where dry so thought it was time to excercise the car
After the usual 10 minute warm up on the drive I set off with my co driver, my 10 year old daughter who is progressing well in becoming a petrol head
We had only got a mile from the house and had not exceeded 5000rpm at all when I heard a huge pop and an alarming cloud of smoke appeared, thankfully we where only doing 10 mph and had changed from 2 to 1st preparing to stop at a junction
The motor died and engine light came on, panic set in and she would fire up but not keep running so I assumed a hose had burst. On popping the hood I could see that the rubber air intake on the lh bank had come off, with some force as it has taken some of the paint off the painted red intake cover.
I pushed the hose back on, recovered the broken clip and thankfully had a zip tie for a temporary fix. She started straight up, no faults shown but there was a little smoke from the exhaust that cleared after 20 seconds. I carefully drove home and am now considering the cause and wether to take her for a check up at my local dealer

I can only assume some sort of backfire caused the pressure build upto blow the hose off,

should I be concerned, the car has been loved and pampered, covered 29k and had a cam belt and major service 600 miles ago!

any advice or comments appreciated
regards
Dave

Hi Dave , what happens all the time is that there is too much oil in the engine and you sucked the oil in to the intake system. If you slide of the intake boot and check inside intake manifold and see oil . You found your problem. You have to suck out the oil , install the boot and maybe reset some fault codes that are in system . After all that , you have to check the engine oil level to see if there is too much oil in the system.Idle the car for about 20 minutes , then hold the idle for two minutes at 2500 rpms and then check the oil level. you will
see that you are over the max level line.
If you are over , who ever changed the oil put too much oil in. You will have to drain out the oil.
GoodLuck

Thanks Alex
its slightly over on the oil level, the local dealer has seen this happen before and as the car is a few years old there could be many other reasons so its going in to have the hoses and clips checked, as well as a replacement ECU as getting false warnings to 'slow down' even before the engine if warmed up
I will post how I get on, unless she gets traded in as 3 red 458'S in the showroom!!

Dave- Oil may have fouled the Lambda (O2) sensor giving you the slow down warning because it thinks the cat is overheating.

+1, if the root cause of your issues is really overfilling of oil, you have a high chance to get a CEL. As Terry said, it can be fouled O2 sensors. But it's also highly probable that your MAF's are dirty with oil which gives wrong information in terms of airflow to the ECU who consequently will make wrong decisions in terms of A/F ratio and deliver a too rich mixture (not enough air). That will lead to cats overheating.

Before your change your ECU's (expensive and do fail very exceptionally), make sure that all sensors are in order.

Question: What are the steps in proper cleaning of oil infected items?

is that a worthy subject to continue or opening a can of worms.

[davesilcock]

All sorted now, car been to Graypaul in Solihull and pleased to find that the car is described as very clean and tidy with nothing wrong at all - apart from the sensors that are now repaired, oh front tyres down to 3mm tread depth but they will wait till the spring
She had been cleaned inside, had a few stonechips repaired and a deep scratch where I dropped my keys, a totally invisible repair so happy
only down side was it was raining when I collected her, a £1500 bill and the matt red paint on the manifold where the hose blew off needs touching up, now to find some paint for that
thanks for your replys, I will be more carefull with the oil next time!!

Funnily enough this just happened to me as well. Sounds almost exactly like what happened to me.

I just replaced the clips and had a look inside the manifold, there was a puddle of oil.

You'd think a trained mechanic would know how much oil to put in?

[RB9]

Btw Hi Stef and Taz!

[wetpet]

One of the most common problems. over filled with oil. find a mechanic that can at least do the most basic service!!!

I looks like it is the most common mistake I've heard of. But as Ed said, a trained mechanic who isn't able to fill to the right level should change job It is really not difficult to respect the procedure of filling oil with a dry sump and to top up the last 1.5l while the engine at operation temperature and is running.
