It did take gall to show up with a lawnmower blade for you to sharpen... He's mechanically inclined but he can't sharpen a lawnmower blade?? The easiest way to get rid of him is to put him to work when he shows up. Seriously - have him clean parts and do other crappy jobs that you would rather not do... He will either help once or make up some excuse and then leave and probably won't show up until you're done with the car. As far as the coolant pipes go, it looks like surface rust - nothing serious. Did you buy new ones? If not, just wire brush them and use some rust converter and paint the areas with some high temp. paint and reinstall them. The oil level sensor end is probably laying in the bottom of the oil pan. Not sure how it would have happened unless someone at one point removed it and caught the end on the hole in the pan.

BodybyFisher Posted June 3, 2007 Author Report Share Posted June 3, 2007 Kevin, Hmmm, you bring up a good point with the oil level sensor. Since it wasn't working and I was getting a code, I assumed that it happened on its own. I don't remember putting a lot of pressure on it removing it myself. There are two parts, the cylinder and a disk the size of a dime, do you think either can be ingested or is there a screen on the oil intake? Good idea, with giving my neighbor a job, believe it or not, I think he would enjoy being put to work, it might make things worse. And you are right he has no mal intent, its not often someone does what I am doing I am sure, so its a novelty to him What did you think of my crossover gaskets?, think they were the source of my coolant smell and leak?. You think the brown stuff is the supplement? I bought new coolant pipes after I looked up last week and saw the rust.., I think you are right, its surface rust and it probably wasn't leaking there...

KHE Posted June 3, 2007 Report Share Posted June 3, 2007 Is there supposed to be some kind of a float on the oil level sensor? Just curious how it senses the level unless it is at a point two quarts low in the pan. Was the original sensor metal at the hex fitting end? It looks like it in the photo. The crossover gaskets definitely look like they were the source of the leak. Mine were a blue silicone and your old ones were orange. When I pulled mine apart, they were still like new but I replaced them anyway. What is the condition of the "freeze plug" that is in the block behind the waterpump crossover? If it looks rusted, it might be an excellent time to replace it. Mine was in good shape so I didn't mess with it and as long as the coolant has been properly maintained, your's is probably OK.

stefank Posted June 3, 2007 Report Share Posted June 3, 2007 Mike, when my oil level sensor went bad, it looked the same as yours, the "loose" cylinder was missing. I think the end cap came loose and fell into the oil pan, followed by the cylinder, which in turn brought on the "check oil level" message on start up. I did not think too much about these parts in the oil pan, and I'm driving my car like this for 70,000 mls now. There usually is an intake screen on the oil pump, no problem with items that size.

Ranger Posted June 3, 2007 Report Share Posted June 3, 2007 I don't know if all GM oil level sensors are alike or not but I would think so. When I dropped the pan on my wifes Bonneville 3800, the sensor was a glass tube with some electrical circuitry inside. No floats. Never could figure out how it worked.

I need to order the inner throttle body gasket, gmotors sent the wrong gasket. I might as well order a new dog bone, new injector o-rings, and a new positive battery bolt while I am at it.. The oil level sensor must be positioned at a level that is 1-1/2 quarts down from full. When you install the new sensor, I would tighten it to "mechanic's feel" unless the instructions had a torque spec. as any torque spec in the shop manual is likely for the metal sensor. You don't want to break the new one. If you are going to replace your dogbone mounts, just buy them from Napa, Carquest or other reputable local chain. I replaced mine when I had the engine out because they were totally shot. GM wanted $80+ each for them and they included some sort of mounting bracket. I bought both at Napa for $25 or $30 for the pair. A year later, they are still fine. The freeze plug on your car is most likely fine considering the frequent coolant changes the car had plus it is a DexCool car. My boss' son has a '95 Olds Aurora and the freeze plug rusted through. I helped hin change the water pump a few years ago. It took an impact wrench to remove the pump and the hose connection stampings had portions that were rotted away... The green coolant had a grey color - that was the most poorly maintained cooling system that I have EVER seen. It is a wonder the head gaskets haven't let go.

I wasn't talking about adjusting the sensor - I was speculating that its location in the pan was designed at a point 1-1/2 quarts from full. Just trying to figure out how it works. I was also concerned if there was a torque spec. for the original sensor, it would be too large for the plastic sensor and if torqued to the metal spec, it would be damagd. I wouldn't use any Nylog on the o-ring as it is not a high pressure connection like in an air conditioning system. Just apply a light film of engine oil to it when you install it. I bought the aftermarket dogbones because I thought the OEM dogbones were such a ripoff. The aftermarket dogbones look exactly line the OEM versions and are reasonably priced. The rubber in the original dogbones fell apart when I removed them so I had to replace them.

Logan Posted June 4, 2007 Report Share Posted June 4, 2007 Engine Oil Low message The oil level switch is a magnetic reed float style switch which is closed with oil level full and open when oil level is low. The PCM monitors the oil level switch to determine if the oil is LOW or OK. When the test conditions have been met the PCM will monitor the oil level switch input. If a low oil level is indicated the PCM will send a serial data message to the IPC. The IPC will then indicate the oil level is low. If the test conditions have not been met then the PCM ignores the oil level switch input and oil level OK is indicated to the IPC. The test conditions include a timer and a coolant temeperature value. The test conditions are needed to ensure the engine has been OFF long enough for oil to drain back into the oil pan.

BodybyFisher Posted June 4, 2007 Author Report Share Posted June 4, 2007 Kevin, I understand what you are saying now, good thinking about the steel sensor vs. the fiber plastic sensor and the required torque, I will just snug it up, good thinking. I will buy the aftermarket dog bones, I think I get a thump when I press the gas at highway speed because mine are loose. I am off this job till Friday. I need to move the AC Compressor and ABS unit off the carriage, disconnect the steering shaft and cut the heat shield on the aft cat O2 sensor. Then break the RF control arm and remove the strut assembly from the LF. Once that is done, I should be able to drop the carriage and get to the reason why I started all of this.... UGH.... I think I am going to have my alternator rebuilt while its out, it will cost about $155 if its the 140 watt unit. At 96,000 miles, since its out, its probably a smart thing to do..

epricedright Posted June 4, 2007 Report Share Posted June 4, 2007 Wow Mike! Looks like you're having fun! Glad to see you're getting it fixed though...I'm sure that's been really heavy on your mind. I wish I could be there to give you a hand. You'll find out who your true friends are...kind of like moving, if you know what I mean. If you need any tools, please ask if I have it before you run out and buy it. Just curious, before tearing into it, did you ever test your electrical connector to your tranny after cleaning it up with contact cleaner? Was it not the connector causing your ISS Speed Sensor problem? I read that you deducted that your crossover was leaking on that connection. Looks like you're doing it RIGHT though! Wouldn't expect YOU to do it any other way. You da man! Ok all you east coasters, get over there and give Mike a hand this weekend! Link to comment Share on other sites More sharing options...
