I had a similar problem and the culprit was the front motor mount. I had a two o-ring exhaust manifold and I was replacing them all the time. I finally noticed damage to the front engine motor mount and I had to replace the damaged half of the case and put in aluminum shims to get a good tight fit. After that, I could get two or three practice session and a race out of set of o-rings.
