I have a 1995 Montero SR 3.5L DOHC 139k miles. It has blue smoke when accelerating from idle. It's a puff of smoke then goes away.

On my 1992 Montero 3.0L the culprit was the valve stem seals. I replaced them and no more smoke. I also replaced them on a 1990 Montero and it fixed the blue smoke problem.

I'm not excited about replacing 24 valve stems. That's going to be a tedious project. <img src="/forums/images/graemlins/zombie.gif" alt="" />

Are the valve stem seals the likely issue? Or is there something else I should check for?
