I did an oil and air filter change today and replaced the oil. Undertray came off easily, oil filter and sumpplug likewise. Filled it up with oil and thoughtr that was quick. Turned the engine on and it soundd like a diesel!!!
Turned it off to see 5 lites of oil on the ground!!
On investigation, the old oil filter ruibber seal had stayed on the engine and when I put the new filter on it must have created a hole for the oil to leak ouit of!!!
Re did the job and another 5 lit-res of oil, car going OK
Phew!!!!

Blimey that could of been so much worse

It's bad enough; now he's got to clean up five litres of 10-40 before the missus gets home!

I thenhad to buy another 5litres.Still tomorrow is another day

You only do it once matey.
Every who works in the trade will have had that happen to them some time

Yep, lol

Did it years ago with an Alfa V6, I think it was a 166.

Left the seal on, didn't realise and then loads of oil pouring out from underneath.

The oil filter was a right horrible, awkward one to get to as well.

Only took me the once to learn my lesson

Haha I didn't put an oil filter back on a car once, turned her on, reveresed and OH DEAR!! Lol

i've forgotten to put the sump plug back in before refilling before... wondered what was lapping at my feet...

Never had any of these issues but I did once sell a newly reconditioned engine to a friend and stressed, several times, that the oil pressure sensor wasn't fitted.......you can guess what's coming next can't you?

To make matters worse, he was fitting the engine into his newly resprayed show car

Hmmm, interestingly he hasn't been in touch for years now!

Been there too when me and my mate changed the oil on my Uno Turbo - they were cracking little cars, anyone had the joy of owning one?? (the owner of the driveway wasn't too chuffed at the time )

Ive had 2 mate

Me too - both mk2's. Loved them. Had two Punto GT's after that - not impressed at all. Got rid quick and moved on to the coop.
