i have had a similar problem with my friends teg its a 93 LS non-vtec, i called the dealer and asked how to take it off. depending on where you are located the acura dealer loaned out the tool for a refundable $75. it backs up the crank pulley to the ground, then you use a breaker bar to turn the bolt. the head of the tool was hexagonal and went in the pulley and a long handle on it went to brace the motor from turning.
