Car Forum / Volvo Cars / February 2007RE: 1985 245 Oil Leak
OK, I degreased my engine today at the carwash and am currently down to 2 problems: 1- Even covering the rotor, something got wet inside and I had to unlock the top and dry the rotor twice. After it dried it starts easily. Should I replace the whole unit? 2- I uploaded a YouTube video of my oil leak and will post the link as soon as the video processes. Until then, I am stuck. Here goes: Front of car, under engine, passenger side front of oil pan - just up a hair in the corner is a bolt that mounts I think the alternator. At one bolt, just below the oil sender sensor is a drip. It looks above the oil pan gasket. I don't see anything coming down from the sensor and I tried to tighten the bolts. It is kind of a tight corner and hard to really see. Any idea what could be dripping in this corner section of the oil pan/engine? -- OK, video processed, here is a link - not sure of the quality. That is grease on my face - I don't have a Cindy Crawford beauty mark LOL. http://www.youtube.com/watch?v=Z0sRM4djcbo > OK, I degreased my engine today at the carwash and am currently down > to 2 problems: > > 1- Even covering the rotor, something got wet inside and I had to > unlock the top and dry the rotor twice.

It CAN be dripping from the sensor, where the wire connector comes out of the plastic housing. I have experienced that several times. Try looking when the engine runs and there's oilpressure. > -- OK, video processed, here is a link - not sure of the quality.

Couple notes on the sensor. 1- Where the wire connects to the sensor in the cap - it is deteriorated. Bare wire. I duct taped it covered to protect the wire, but I did remove the sensor connector and it is wet with oil inside the sensor. 2- My oil pressure light on the dash does not come on under any circumstance - turning the key, starting the motor, stopping - nada - no light. So, you are saying it is actually possible for oil to leak out of the sensor? If so, perhaps the broken connector has stopped sealing oil inside - if it does such a thing. > > OK, I degreased my engine today at the carwash and am currently down > > to 2 problems: [quoted text clipped - 31 lines] > TT600-83 TT600-84 HD-68 > TEA20-56 121-67 121-69 122S-69 245-84 245-87(TD) 245-92 > Thanks. > So, you are saying it is actually possible for oil to leak out of the > sensor?

Replace it with a new one, they don't cost fortunes, and you will have the oil pressure light working again also.

I unplugged the connector and did not notice any oil coming out of the sensor, or out from around the sensor. It has to be something under the alternator that I can't see from above or below. > I just checked the sensor - it does not seem to be leaking.

Well, it's been a long time since I was wrong in something when the subject is Volvo 240, but then I haven't seen your car IRL... You must loosen and take out the alternator and see behind it. It _can_ be the gasket on the timing cover in front of the engine, or the camshaft seal, letting oil out behind the timing belt cover and down the engine. Let's hear what you find out, this have me puzzled! Want to see how a Volvo _can_ be used?

I will replace the sensor and will be VERY happy if that is the cause. Jamie > The engine wall is wet behind the sensor, I just can't see anything > coming out.

Ola, For the moment, in the words of Edgar Alan Poe, "Thou art the man!" I saw at FCPgroton.com that the oil sensor has an o-ring. So, I pulled my sensor and used some form-a-gasket in a tube to seal the sensor. Voila! The leak stopped! O-Ring was gone. So, now I have a 1985 245 Wagon with 230,000 miles for $700 and NO LEAKS! Cross my fingers, that is NICE. Thank you. James, as always thanks. I am sure I will have more to come. Jamie > Ola, > For the moment, in the words of Edgar Alan Poe, "Thou art the man!"

Only other thing under the alternator is the oil pan, unless the block is cracked, but that's rare. Regarding the light on the dash, unplug the wire from the sensor and ground it, if the light still doesn't come on replace the bulb. Personally I would add a guage, you can get one from any GL or Turbo, along with the sender. It was an option on DLs. > Thanks. > So, you are saying it is actually possible for oil to leak out of the > sensor?

Now the video worked, and even if it's hard to see anything at all underneath there, it's the right location and amount of oil when the sensor is leaking. Change it, and it will be okay, I would be very surprised if it's another fault.

Yeah that happens sometimes, it's dried out, it sounds like things are fine, why would you replace it? > 2- I uploaded a YouTube video of my oil leak and will post the link as > soon as the video processes.

It's likely the pan gasket has a chunk out of it and replacing the gasket is the only way to fix it. Do make sure it's not coming from the sender though, that gets high pressure oil so a leak there, while rare, can really spew a lot of oil. Regarding rotor, I couldn't start the car for 15 minutes after washing engine. Don't know how I knew, but I pulled the rotor cap, dried the rotor with my shirt and it started. Then it wouldn't drive and it stalled. Couldn't start the car for 10 minutes. Dried the rotor again and it started. I am wondering if it could get wet in rain, humidity - etc and I need to replace it before trouble happens. thx. JB > Regarding rotor, I couldn't start the car for 15 minutes after washing > engine.

If the cap is cracked or any bits are missing then yeah, replace it, but otherwise just be more careful. A squirt of WD-40 works pretty well to dry out the cap and rotor. Agreed. I'll leave it be for now. Thanks. |
