I have a 2001 mazda b3000 with a 3.0 liter engine. Head gasket were replaced because of overheating. Heads were checked for warpage, and for possible valve damage and cracks. Heads were checked out fine. Installed using new head bolts, torque the heads in sequence and in three steps to factory specs. Also the rocker arms were also torqued down in two steps with using the factory specs. Never did the timing was touched and it also has a distributorless ignition. Coil pack, spark plugs, ignition wires, crank sensor, thermostat and gasket are all new. The engine turns over a little then binds, like if though something is jambed, then it will spin a little quicker, then again turns slowly as if something is jambed again. I'm at a lost at this point on what to do. Please help!

Were head gaskets installed correctly? Check for water in one of the cylinders sounds like it may be hydrauliced.

That was one of the first thing I looked for, but no water in none of the cylinders as I spun the engine over with all the spark plugs out, also I've done a cylinder compression check, each cylinders are at 150 psi. Also the head gasket has the left and right side with the markings that says UP for installation. With all the I've checked this engine should start up. Any other advise would be appreciated.

Try resetting security system that may be the problem. I don't know how on a Mazda or whether its' a key type security system. I really can't think of anything else other than a valve being to tight. Rocker arm bolts are only torqued to 24 ft. Lbs. Though try spraying choke cleaner into throttle if it starts then its' a fuelproblem.

Will try that as soon as I get home from work today. And will go over the rocker arms again just to make sure, I know they have to be torque down on the compression stroke at top dead center. Thank you for your advice, time, and patients, have a bless day.

Hi again.I failed to mention during installation of the lifter I did not put them in a bucket with oil. Would that make a difference. Also if the valves are too tight would it cause these symptoms. I was going by what the manual says during tightening specs for the rocker arm adjustments. Also would I have to take the lifters by out then put them in oil or just get a new set. Thanks again for your help.

That is why isent the specs for torque, if the valves are to tight it would casue it as well as not putting lifters in doil to pump them up althought the oil would take cre of it self once it was started. Check the rocker arms for being to tight.

Thanks again for the info.I will pull the lifters out inspect them good and if so.I'll just replace them if I have to. The rocker arms where tightened 132 inch pound for the first step then 26 for the second step. Sounds too much. Let me know.I'll just redo that whole process. Thanks!

Why don't you just torque the rockers to 24 ft lbs and see if the thing will start. I can offer no other suggestions.
