I am taking my heads off and the cam pulley bolts seem pretty tight. Any one have any good ideas on how to get the cam bolts loose? I do have a cam pulley holder.

 

1/2" breaker bar and plenty of muscle!

 

I have tried that. Put a cheater pipe on it too. The engine is still in the truck and it is hard to get position. I was wondering if they are a back ward thread.

 

Regular thread, but tight, especially if they haven't been off before. Use an impact if you can get one, or get a longer breaker bar.

 

I just got done with the same operation and I tired everything under the sun to get those darn things off and nothing worked....until I picked up the Schley SP 96800. worked like a charm. Expensive though. After shipping it's like 50 bucks. I got a hold of the Cornwell tools rep in my area and bought it from him since I was in a hurry. They're a bit spendy, cheaper than Snap-on, but more than the base cost online. Include shipping, you're about at the same price. After you get your bolts off, you've got a heavy one-trick pony tool.....best to stash behind your door to knock out the bad guys when they break into your house. Good luck!

 

I know on the '93 3.0 v6 I took the heads off of there is a machined hexagonal section in the center of the cam-shaft (under the valve cover). You can put one guy on a wrench holding the cam this way and have the other guy use a breaker bar on the bolt. Be careful when it breaks loose. Reverse procedure for installation, I recommend using a torque wrench. They are usually damn tight.

 

My neighbor had a $400 dollar air impact tool that we used and it barely did it.
