993 Oil leak panic!!!

[dsmith968]

My 993 engine bay and underneath the engine itself has always been completely dry with no evidence of any oil leaks whatsoever. However, after a local run in the car over the weekend I have noticed several spots of oil on the floor in relatively close proximity to each other. (In line with rear wheels slightly to the right).

I checked under the car and seem to have located it to the oil filter itself or maybe a pipe from/to the oil filter. I have heard that this is fairly common on the 993.... 100% sure the leak has only just started and after some playing about seem to have temporarily cured it. Anyone else had any experience of this problem ? Is it serious ?

Very common problem - has the car been serviced recently?

There are two oil filters, a large one by the dry sump tank in the right hand rear wheel arch, and a small one tucked up on the side of the engine casing, just to the right of the centre line of the car.

If the small filter is not done up REALLY tight then it has a tendency to leak like this - when i sold my C4S the guy had it serviced at his local indie and a month later had an oil leak. He happened to be coming past my house so dropped in, and i fixed the leak there and then.

I think sometimes the small one doesn't get changed and there have been instances where it has rusted through (!!) leading to leaks.

i had the same awful feeling , when my 'dry' 2s suddenly started leaking in the way you describe yours...common fault, its the engine filter that actually corrodes, if its not been changed for a while. the result is oil, leaks through the crack, down the outside of the filter, onto the tray and eventually on to the floor...result, awful feeling!!!!

change the filter, and problem solved, the moral being change the filters at every oil change, not every two years, as advised by porsche.

Hope this helps..

Happened to mine, and mine ended up leaking quite a bit due to the hole in the filter!!! It's a simple service item change so as you can guess I was very relieved

Alex, did you see my suspension response on the other thread? Call me if there's anything else you need to know, i have just done all the legwork myself!

This is a very common ocurance and can easily be rectified as mentioned above replace both filters.

The 1 behind the wheel arch liner can do the same thing just corrode through like a pin hole and it gushes everywhere....never had this problem with the ferraris that run the filters on the floor ie: 550 maranello or a 456...even a testarossa doesent do it ? Just cheap filters perhaps...ive had some out of a box (porsche) and the paint had been flaking off in chunks....well they can go staright back mr van driver...is what i t old the chap who delivered them to me.

thanks
