I have a 2004 Saab 93 turbo. It leaks oil from the oil filter cap. I replaced the gasket when I changed the oil and oil filter, but it still leaks. What should I do? There are so many people out there with the same problem that have taken their saabs to so many garages but the mechanics out there don't know where the leak is from, I figured it out the minute I saw it. Please help. Thanks

While there are a variety of reasons your Saab 9-3 is overheating, the most common 3 are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.

You need to check for an engine vacuum leaks like at the intake gasket. Use a can of carburetor spray and spray it over the intake area, if the engine changes sound you have a leak.

Check the oil sender (for light or gauge) or the oil filter seal (replace the filter)

#1 Heat up engine to make oil flow better
#2 Put car up on jack stand or ramps
#3 Place pan under engine and remove filter being careful not to burn yourself
#4 Remove oil plug from bottom of oil pan carefuly because oil is hot.
#5 Oil rubber gasket on filter and install filter and oil plug
#6 fill with recommended type and amount of oil

dear friend- your turbo is not oil coold,but if you put a pressure tester on pump it ti 15psi and then let it stand for a while look for external leaks if nothing see if the pressure has dropped,if no external leaks were found and the pressure has dropped,it must be internal,if the pressure did not drop then i think the water cap is faulty.

Look in the narrow open space between the 12 volt batty and the black plastic valve cover (which says SAAB turbo. Look straight down. It is close to the oil filter cap if you already know where that is. But farther down on the engine body. The "Automatic Transmission Dip Stick" is the short green plastic thing next the to tranmission housing. It is held in place with a bolt. It is accessible only from below when the car is on a lift

as the turbo is cooled by water and if the bearings fail yes its possable if the car is auto the rad has a oil cooler built in to it or the auto box or at the worst head gasket

First, it ain't easy.

I finally found the oil filter with its screw off top. It is on the right front side of the engine (left of the Battery) and just visible (with a flashlight) about two inches below the black plastic cover. Removing the cover is unnecessary and doesn't help much even if you do.

I slipped a CFA size 6 filter remover cap over the plastic top - I think that you can also use a 32mm ratchet on the hexagonal molded piece on top. In either case, I suggest applying a bit of new oil by finger around the edge of the screw on cap prior to trying to ratchet it off - either with the CFA size 6 or the 32mm fitting.

It comes off counter-clockwise and you won't have much room to work - about 3 inches of play. Once you get it started, remove the ratchet and remove by hand. Have some paper towels to wrap around the assembly when you remove it.

Discard the old inner filter and install the new one. Remember to look at the old one before you remove it so you can install the new one correctly.

Finally, by hand reinstall the filter and cover. Twist the cover on clock-wise until it is hand tight. You can use your ratchet to tighten and extra quarter or eighth turn if you like but I don't feel it is necessary.

Hardly worth doing yourself but a change at a garage with 6.3 quarts of 0W30 fully synthetic oil cost a pretty penny.

Sounds like it's time for a compression check. The head or gasket could be blown, and this test will confirm or deny this fact. Your smoke/steam and the oily residue are pretty good clues...accordianman

Yes, filter is under plastic cover, and be sure to use SYNTHETIC OIL ONLY! Good luck!
