Defective part for seal

I bought 2 sets of rear main gaskets and installed one on a new engine mounted motor and the rear main motor is leaking badly now I have to pull out the 4x4 transmission to replace it! And I can't contact the seller

Pros
  • seal
Cons
  • The list is getting long.

Leak Costs Hundreds of Dollars

This product leaked after installation and I had to remove the transmission again which cost me hundreds of dollars to repair again with a GM OEM part after this installation had no leaks. The gasket and gasket didn't fit the lid perfectly, but the gasket didn't leak.

Pros
  • Automotive
Cons
  • Available in Black Only

GARBAGE, DO NOT BUY, BEWARE!

Used on 2009, 6.0 Avalanche 4x4. Started watering 10 minutes after launch. I've been working with cars for 25 years. I've never had a rear seal leak like this before. When I assembled the engine, it was lying on the table. Not a hack job. Professionally with torque wrench and seal alignment tool. this is a joke I'm angry 😑. I have not read any reviews before. But apparently everyone had the same problem. Very bad quality. You get zero!

Pros
  • Parts
Cons
  • Communication with Seller

Don't buy everything - gaskets

I paid a mechanic to install this in my suburb and the gasket was damaged right away. I only had one drop before I bought this product after I installed a gasket kit at a mechanical shop, installed a gearbox and the exhaust was put back into the new gasket kit and oil poured out of my engine like there was no gasket at all or seal. Well guess my returns window is closed and I had to pay double work for a defective part, I wouldn't recommend this gasket set and if I could give a zero rating I…

Pros
  • bearings and gaskets
Cons
  • wrinkled
