1991 Honda Accord cyllinder

My mechaninc claims that my car thru a cyllinder thru the engine due to high rpms. Could this be a result of the origanal repairs he did.

I brought the car into the shop to have all seals and gaskests replaced specifically the rear main oil seal. After retrieving my car I noticed that the transmission would no longer "automatically shift" and it would not come out of "sport". I ALSO noticed that the car was "missing" real bad and was still leaking oil. I called the repair shop after breaking down, they came and got the car for a second time and again "repaired" it. After retrieving the car the second time, 1 day later and 40 miles from home the car broke down again. This time catching on fire. (Florida highway partol was able to extinghuish flames) the repair shop again retrieved the car and said that there was going to be more repairs needed that were not covered under his 2 year 24000 mile warrenty and the origanll repairs. (The timing was off by 1-2 teeth [the timing belt was replaced on the 1st trip to the shop] the timing was corrected on the second trip to the shop)
