Can anyone please help. Finally got a break from the cold and I changed the oil in My 75 Lesabre. Crank her up and the oil pressure light comes on.:idea2: So I switch the car off and get out to see what the problem could be. I step into this massive oil spill. Long story short. It was pouring out of the oil filter. I realized my mistake might have been that it was a FRAM filter. So run down to the parts store and purchase more oil and new filter and put it on. Crank it up and BAM. Same thing again. Does anyone have any idea whats wrong. The filter was hand tighten and then half turn with oil filter wrench. 455 BBBray:
I got my '73 for cheap money because of this exact issue. It left a puddle the diameter of a basketball for every minute the car was running. The time it took to start it and drive it onto a flatbed left about a 2 foot puddle. In my case it was the oil pressure sensor. The plastic housing on the sensor was cracked and was spraying oil out and making a huge mess.The sensor is right behind the filter (towards the firewall) and if the wiring connector is covered in oil then I'd say you have the same problem I had.
I know for a fact that a stuck gasket will cause that very same issue. I have done some road side assistance for a couple of friends who have done oil changes and forgot to double check the gasket on the old filter to make sure it was still on.:Smarty:
Or the little valve relief in the oil pump is stock, then you will blow the oil filter loose over and over. Dont ask me how I know this:Smarty:
Thanks Brad. That was the exact problem. One small piece of the old filter about 1/4 of an inch long....SMHou:
spread a little oil around the rubber ring before u install the filter and that should resolve any future problems.
Well if I didnt have bad luck I wouldn't have any. Finally had a fairly warm day and decided to crank her up and I guess you know what happened next.:af: So since I will be sending her to the body Dr. next weekend I guess I will pull the engine and tranny and inspect the entire thing..
It is leaking somewhere around the filter. NOt exactly sure where but the filter is still tight and intact. o No:
In order to find exactly where the leak is, the area needs to be perfectly clean and dry. The trick is to spray the area with some brake cleaner, then hit it with some compressed air to dry it off. Once the area is clean of oil and dirt, it will be much easier to pinpoint where the leak is. Also keep in mind that oil leaks down, so it might be leaking further up from where its actually dripping from. So this all started right after changing the oil and filter? Check the oil filter mounting surface again. Take your finger and run it along the flange, make sure there is no gasket material that you might of overlooked. No offense, but its a little silly to pull the engine because of this. Thats like killing a fly with a Sherman tank.
The old gasket has to be stuck on the housing. Either that, or the new filters were the wrong size around the sealing surface. Doubling up the rubber gaskets from filters always results in a massive oil spill.
Well I have to pull to pull the engine any way to do some upgrades and getting the engine bay repainted. I have tried everything that you guys have suggested so far. What I am wondering is if the threads on the housing bolt are stripped out or not from the previous owner. Getting ready to start turning bolts now since the body shop will be here later today to get her. Will let you guys know how it turns out and will be posting pics of the work. Thanks for all of the feedback.
This summer I found a stripped bolt in my oil pump/filter cover and had to search my old oil pump kits for a slightly longer bolt to grab some threads. It worked.
o No: Ok. I am still kind of green but I have changed oil in many cars for years. On the bottom of the oil filter housing reads METRIC. I wasnt aware of GM using metric sizes in 75. Please someone enlighten me
