Tbh it could have been a faulty oil seal on the filter rather than the filter not fitted properly, had that happen on a friends 100hp at the beginning of the year and it dropped all it's oil after he booted it away from the lights, was fine for the first 5 mile previous.
Hi ,
I'm intrigued by this..( as an engineer),
as that's whats alleged to have happened to my Panda,
how did the seal "fail",
split in half ?, break-up ?,
as far as I 'm aware most "cannister" oil filters have a retaining groove that the Square section oil seal sits in, once it is screwed onto the stub and lightly tensioned - the oil-seal is then captive on FOUR sides.. ,
quite how a seal can then fail is quite a feat..!!,
Imagine if you pulled-over to find a piston sat on the ground under the car.. , that too should be constrained by FOUR faces,
I'm fascinated to find out, as mine was remedied under warranty so I never got to see it.., however there was such a HUGE loss of oil , I thought I'd blown a crank seal.. another cannister oil-filter was certainly the cheap option...,
