lower oil sump drain plug thread repair
 

Drain plug thread on my lower oil sump got damaged by my idiot mechanics. I don't trust them to do this repair. So, I bought the timesert kit and repair it myself. I know that I can just repair it without taking the lower oil pan off but I want a clean repair and don't want the risk of having some debris left inside the pan.

Timesert seems to be better than heli-coil and perma-coil. It's like a solid thread bushing not just a coil. I bought the whole drain plug repair kit. Even though it's quite expensive but it's worth every penny. After the repair is done, no more dripping now.

Once the pan is off. Just drill out the damaged thread. Counterbore it to create a place that thread bushing collar will sit on. Then install the thread.

I like TimeSert better than Helicoil... but it may just be personal preference. Both are good stuff!

Good job there.

How can a "mechanic" strip a simple, large threaded drain plug?!

I think they just torqued it too much. He even tried to get away from what he did. He said it was damaged by the prior shop. But I was sure the oil change was done well in my prior shop and I had not seen any dripping oil on my garage floor. And he told me that after he finished the oil change. If it's really done by prior shop, he would tell me before he went ahead to perform the oil change, right?

Then he said he will repair it in the next oil change and just put some silicone around the plug. I will never send my cars to them again. That is not the jiffy lube quick oil change shop. They specialize and work only BMW. :dunno:

what the heck? looks like someone is using program to hack our forum.
