Hi, i'm new to list and have a new to me 993 Cabriolet 1997. I've been searching the forum to try and find detailed instructions on how to change the oil and filters. Couldn't find anything in the DIY section. I was hoping for some pics with step by step instructions. Does anybody know if this exists and where I can find it? Thanks.

Changing the engine oil on the Pcar workshop site.

Have fun with it. I know I did.

Got it. Didn't know about this p-car site. Lots of info there. After reading MTS's oil change I have second thoughts on doing it myself. So much easier on my old 968.

Thanks.

If the oil return line that you should remove to get to the engine oil filter hasn't been removed in ages, it can take a bit of time getting it to budge as the two O-rings on the line tend to stick very well within the bore.

It took me some twenty minutes to get it off since I chose not to use a screwdriver to pry it off.

Its really not that hard but there are more tasks than with most cars. You've got 2 plugs, 2 filters, rocker cover and perhaps an engine tray. You've also got a larger quantity of oil to deal with. Filling has to be done slowly or you'll make a big mess.

If you're mechanically inclined, try it yourself. Lifting the car is a criteria and things would be much easier if you have a lift or pit?

It's more involved than with "normal" vehicles.

If you have it done, go to a place with 993-experience even if it costs a little more.

its not hard.

I wouldn't remove the oil line, never needed to.

The turbo is even more annoying with 2 extra turbo sump plugs to remove.

The standard 993 is a bit tedious, but its not difficult.

Agree with Quad...no need to remove the oil line.

I would recommend picking up a "Form-A-Funnel" for when you drain the oil tank...it is in a tough spot to get a normal funnel and it will run out all over the side-skirts making a huge mess. The FormAFunnel made it much cleaner.

You don't absolutely have to.

The shops that changed the oil before I took possession never did. In the process, they bent the engine tin slightly...its just not the way I do things.

Another advantage to removing the line every time you change the oil is that I can pre-fill the oil filter with oil and it makes removing the line easier, when you have to.

Downside is I end up replacing the two O-rings each time. I know I don't have to...its just the way I do things.

Welcome, TARBENDER! Changing the oil and filters on a 993 is one of the "rites of passage" which will help you bond with your newly-acquired vehicle. It will also lead to the next phase of ownership, what we fondly refer to around here as "The Slippery Slope".

I can't see how that would bend the engine tin at all. The filter slips out pretty easily once you remove the orange heater tube.

pre-filling the filter is great, but I crank with DME out, so I'm not too concerned there.

I guess either way is fine, but those lines and fittings always make me nervous wrt rounding or stripping those fittings.

I removed the feed oil line every time - why? Because it gets more oil out of the bottom of the tank, and from the oil pump. Its easy and fast, clears a straight line to the secondary filter. Been doing it that way for 11 years now, never had an issue, and I have done quite a few different cars.....

There is a tab on the line that is designed to be pried - I used my trusty 3' long screwdriver which has a very large face and apply some pressure, while the other hand holds the line and wiggle it - usually the line just slides out.

I do not pre-fill the filters, fill with 7 liters oil, pull the DME, and then crank until I see oil pressure, maybe 1-2 bars. Put the DME back in and fire it up, run for a minute, shut it down, and then top up the oil. Usually 10 litres with both oil filter changed, tank and sump drained, and feed line drained works fine.

Cheers,

Mike

It's really not that hard and a great way to get acquainted to you new 993. I did it last weekend and it took just under 2hrs start to finish (w/ clean up) and I really wasn't trying very hard.

I don't remove the rear wheel or the oil tube and have no problem getting either filter out.
