Hey

Went out last night and bought some cheapo ramps so I could track down this little oil leak I have. I'm now leaving a little 3" oil spot when I park overnight on a clean driveway...

Heres what I found.

It looks like the lower oil cooler line is seeping pretty bad on the engine side where the rubber meets the metal. The top one is seeping also, just not as bad. Just had the OPG done last year, so I was relieved to see a clean oil pan.

It looks like the lower radiator hose has to be removed, and maybe just the oil filter on the engine side??? This is my first "big" job so any help would be appretiated.

PS. I wiped the hoses down before I took the pic. They really do leak I promise

Thanks
Parker

Parker,

Just to give you a little info., there are 2 sealing rings Pt. #900.123.118.30(one for each screw socket (fitting)) which also could be a source for a leak. The fittings screw into the block and the hoses screw into the fittings. When you remove the oil lines you will have to hold the fitting/socket with another wrench to break the hose loose. If you don't the fitting may turn. Mine did.

In addition to the hoses and fittings just check your oil pump area and make sure all your leakage is just from the hoses. The oil pump has a shaft seal and a large "o" ring that can also be a source of leakage in that area.

Good luck

Order your oil hoses now. When they arrive then start taking things apart.

The easiest way to do the job is to remove the fan shroud, oil filter and alternator. The you have all the room you need.

Hey

Thanks for the tip.

After I wiped the hoses off, I started my car briefly to get some oil pressure and it looked like it was leaking right where the rubber/ metal meet.

It is hard to tell though, I guess it could be coming from above dripping down the lines as well.

Guess I'll find out

Hey

Thats cool, I thought for sure I would have to pop that lower hose off and drain the radiator.

I already buttoned her back up to take her home. The fan shroud looks easy to remove, but what about the alternator? Just a couple bolts, undo the wires, and vent hose and remove?

Again any help would be greatly appretiated

Thanks
Parker

Hey Parker....what model year ?

Just asking because I am in the process of adding the mother of all oil coolers to my 85 and will be making up new lines. (Mark Anderson is sending me a set of old lines so that I can canabilize the fittings and silver solder a -12 an fitting) I'm not sure how pricey the new lines are....but I may have a set of good used lines to offer you.

Just PM me if you have any interest.

Good Luck.

Fan shroud removal has been discussed a billion times. Search.

No need to completely remove it. Loosen and remove the belt and remove the bits that are used to tension the belt. Then you have one 13cm long bolt that hangs the alternator. Remove the vent hose and the big bolt and then just hang the alternator out of the way being careful not to put tension on the harness connections.

Hmmm... now that I think about it... scratch the alternator... you can get the wrenches in there with just the oil filter out of the way.

You will need to turn-out the fitting from the block for the lower hose in order to be able to get a wrench to the upper hose. You will need a new crush ring when you re-install the fitting and torque it to spec with a torque wrench.

I replaced those hoses on my 90' S4 without disturbing the block adapters. I didn't consider them expensive, but I bought them from the discount Porsche dealer.

Normal open-ended wrenches won't work on the adapters. I used one of these off-set wrenches for counter holding the adapter while using a normal wrench on the hose fitting ....

You'll still need to double up it with a closed-end wrench in order to get enough leverage.

I had the same problem but after new lines, it was the oil radiator that was leaking, stopped when I changed that one to.

Parker's 928 does not have a separate oil cooler.

Hey

Ken, my cars an 88', let me know if you think they'll fit.

Might go with new ones anyway, just to be safe...


Dave

So you think this can be done with the alternator still in? That would be great...
If I have to loosen it to make to make life easier, no big deal either sounds like.

I'll order the hoses, and block fittings next week, and go from there.

Boreland, thanks for the tip man, I"m always looking for an excuse to buy more tools. The worse part is Northern isn't but a 30 sec drive from my house

If you got anymore tips keep them coming, this is my first real DIY adventure...

Thanks again
Parker

Crush rings. Not block fittings.

If you get the funky wrenches (FW) then you will not need the crush rings as you'll be able to leave the lower fitting in place.

Make sure you get the right size FW. IIRC it is either a 24mm or 27mm. But you should check yourself.

Andre Hedrick

How about adding one, anyone done this lately?

David L. Lutz

Parker,

The crush ring Dave is talking about is the part number I gave you in my first post. 900.123.118.30 (you need 2)

What about having new lines made? With new ends? Who does this kind of work?
