Hey guys, just wanted some quick insight before taking my car to the mechanic. I have a 2012 991.1 S. I had an oil change done 6 months ago and also swapped the drain plug as i noticed it was stripped from the previous owner. Havent had an issues until now, I noticed an oil leak in the garage. Seemed like it was coming from the drain plug, so I tried to tighten it by hand with a small allen wrench but it seemed tight. I probably didnt have the right leverage. Im thinking maybe the oil pan is drain plug is stripped and the pan needs to be replaced. Weird that it started leaking now. Hopefully its not leaking from anywhere else. its leaking pretty good. attached are some pics. thanks!

 

Yeah thats certainly your problem. When you changed it did you have a new crush washer as well? I've done some without changing it and they were fine but others leaked after time. Always get a new drain plug when changing the oil as well. You can buy them for $6 each on eBay. Highly recommend.

 

It's probably the crush washer. If you reused it, they can leak eventually.

I echo Viper - a new crush washer every time is a must. Drain plugs, I do a new one every second oil change.

Also, if you don't have a torque wrench, invest in one. Even just a basic one. You want to make sure that drain plug is torqued to spec (37 ft lbs). And, since it's part of the same process, the torque spec for the plastic oil filter housing is 19 ft lbs.

 

really, even this much oil? I drove it alot the past 6 months and now its leaking haha I cant remember if I changed the crush washer. I cant remember if it came with the new drain plug but ill look into it thanks!

 

+1 on the new crush washer with each oil change. They cost 30 cents when purchased by the dozen.

 

Usually, the new washer comes with the new oil filter and rubber gasket for the oil filter housing

 

We defintely didnt use a torque wrench. I watched my mechanic do it. He works on plenty high end cars, not sure why he never uses one haha

 

I mean, a mechanic that does this all day can probably judge the torque by feeling pretty easy. But for me, I'd rather not take that chance

 

Im pretty sure we used the new crush washer. Im taking it to him tomorrow, hopefully it just needs to be tightened. alot cheaper than replacing the oil pain.

I tried using those small allen keys and it was really tight but thats probably because I have no leverage. He texted me asking to try to tighten it myself but its not budging

 

nice color 991 btw, whats it called?

 

Thanks! Just plain 'ol guards red.

Also, and I say this as someone who is not a mechanic - I would NOT tighten that plug anymore. I'd remove it and install a fresh washer and plug. Unfortunately, you're going to probably have to either fully drain your oil, or be very fast and keep track of how much comes out between the plug swap

 

Happened to me however 1 day after picking it up from service. They reused the crush washer. Similar sized leak. Got another oil change with a fresh crush washer and that was the end of it.

 

check the oil filter..it may be dripping from there

 

good idea, Ill check!

 

Something to consider.

The crush washer was stuck when the drain plug was removed during your oil change and the mechanic didn't realize it so now there are two washers in place.
