Disappointing Gasket for Automotive Use

Based on my experience, this gasket did not meet my expectations. While it fit properly and seemed like it would work well, within a short time it began to deteriorate and leak. The one positive aspect was its ease of installation, but that was quickly overshadowed by the issues it caused. Unfortunately I cannot recommend this gasket for anyone looking for a reliable solution for their automotive needs. .

Pros
  • A high-quality and reliable replacement gasket for your vehicle.
Cons
  • May require professional installation to ensure proper fit and performance.

Impressive OE Gasket

The ACDelco Exhaust Gasket is A solid choice for any vehicle.Based on my observations, this product has exceeded my expectations. The OE design ensures that it would fit the car perfectly, creating a tight seal that reduces noise and emissions. The gasket is made using high-quality materials that offer excellent durability. Unfortunately, the ACDelco gasket is quite expensive compared to other options on the market. Nevertheless, it's a worthy investment that guarantees excellent performance..

Pros
  • Perfect fit, excellent durability, reduces noise and emissions.
Cons
  • Quite expensive compared to other options.

Worked perfectly!: Replacement parts

Replacing a faulty EGR valve with an OEM GM part from Revain solved a pulsation problem on my 2001 Saturn SC2. This would have been a 5 star rating except that no gasket was included even though the product description said a gasket was included. Oddly enough, there was a plastic wrap from the seal in the box. Someone removed the seal before shipping

Pros
  • EGR valve seals
Cons
  • poorly thought out
