Just as described
Have a 86 Cutlass Supreme with a 3.8v6. Had a stock oil filler neck on valve cover. Not the same ones as the GN/T Type, but gasket was the same measurments as my old one that was shot. Couldn’t find any oil caps that fit my valve cover. Ordered this to give a try and it was a perfect fit.

Great product, better than OEM seal.
The quality of this oil filler tube seal in my opinion is far superior than the factory OEM seal. I can see this seal lasting for a very long time. Fits perfectly and no more oil seapage between the filler tube and the rocker cover assemble. Very happy and would highly recommend the purchase to anyone.
