G'day all,
Looking for some insight as how to go with addressing an issue on my car. I have a mild oil leak that appears to be coming from my sump plug but I am unsure now. Below are the investigations I have done.
- First noticed bottom of sump wet and dripping oil (maybe 2 drips overnight)
- Cleaned area, appeared to be coming from sump plug area.
- Changed oil/filter. It took a breaker bar to undo the plug and I noticed there was no washer on the plug (won't be going back to that mechanic)
- Torqued plug to 42nm (minimum number my wrench will do, I know 35 is recommended)
- 1 week later I checked my work and the bottom of the sump is wet with oil again. No drips though.
- Felt around the edge of the sump and was dirty, but not wet at all.
- The rear of the sump where all the heads of the 10mm bolts are was sticky, but not wet at all. Appeared to come from the U joint on the tailshaft that flicks grease everywhere, it also looked very old.
- Re-torqued sump plug and got a 1/4 turn out of it before the wrench 'clicked'
- While under car I noticed a small wet area on bottom of turbo, area below turbo had no oil on it.
My questions are.
1. I have read that long-term over tightened plugs can cause the sump itself to crack. Has anyone heard of that with the 150?
2. Is it possible for the sump plug to un-do itself? Hence the ability to turn the wrench further.
3. Any other clues as to what it could be?
