Should be fine, if you can fit it. Just the other day I used a huge screwdriver in front of the connecting rods and away from the inside of the cylinder wall. In retrospect I should have wrapped in a rag, and used an "impact wrench" in the form of beating the snot out of a 1/2" breaker bar with a mini sledge. After 17 years of MA road salt, nothing less would work.

I also read about threading bolts through the pulley and wedging them against the timing cover. But all that got me was a new timing cover after breaking the webbing on it, and the ill temperament that led to the above measure. Good luck.
