it means the model number , which is mentioned on the name tag on the motor top or on the side , depending on where the manufacturer puts it.
on top the intake on the case
Take the top cover off. standing at the back of the motor. Look inside the motor housing at the upper left top part of the motor housing. Not the cover. Just look around the top edge inside where the top cover mounts. You will see it right there at the top back left side inside the housing. Hope this helps.
The solenoids on are located on top of the motor on a Mazda 3000 Truck. They open a number of different valves as needed depending on overall driving conditions.
Take number 1 plug out, put your finger in the plug hole turn motor over manually preferably, when piston is at top dead center it will blow air out of number 1 hole.
I am assuming that the number being refered to is the casting number. The casting number is located on the driver side bell housing flange on the top. This part of the engine is very close to the firewall and will likely be close to under the power brake booster.
connect a 12v power supply to top motor to see if motor works sounds like motor is bad
the convert top motor is in the trunk behind the vinyl top collector or the vinyl top shoot. you cant miss it.
11:00 o'clock as viewed from the top of the engine.
on pajero block its on back of the alternator and on the colt its on top of starter motor behind fuel pump
With it out, rotate the motor over until the number one piston is at top dead center, on the compression stroke. The piston should be at top, with the timing tab and balancer on th 0 degree mark. Then drop it in where the rotor is pointing at the number one cylinder. This is also number on on the cap. The timing will be close enough to start the motor and set with a timing light. You can pull out the number one spark plug and feed a coat hanger wire in the hole to "feel" the piston move up and down as someone manual rotates the motor over.

More than likely it is the bushing in your motor mount. Just have a mechanic change out your top motor mount...
