You can see if you look carefully at the lower pix that the GM (black gasket in the front) is shorter under the timing cover than the VR. Not only that but the GM gasket material that runs under the timing cover itself is actually thinner by about 1/8". When I put the VR gasket on for a dry fit the pan sat about 1/2" above the block where it should touch the rails of the block, I could stick my finger in there. When I tightened the pan down with the VR gasket the gasket bulged out in the front right under the timing cover, it was very obvious it did not seal right. That told me something was wrong and I didn't want to have to crawl under my vett after getting the motor back in to try and install another pan gasket, it is a job that will have you speaking lots of Chinese! Also I went to the local auto parts store and looked at the Fel-pro #OS34500R and it is the same as the VR and different from the GM. and it was grey. The physical differences between the two gaskets is undeniable and obvious. I have had two of the VR gaskets now that did not fit, they came from Rock Auto. I can say that they were very good about returning the newest one that I did not install, even paying for return shipping! This could be a fluke, but I really would not want to crawl under my car EVER again to replace that pan gasket  ! I have done it twice!! |
