My 1985 mazda rx 7 1.1 gets glowing hot where exhust comes out of the motor , replaced exhust pipe and muffler but didn't help have any suggestions

Check the ignition timing.
Make sure the fuel you are using is specified for engine use.
Last one will be to check the catalytic converter if it still open.

Hope that helps!

Have 1995 olds cutlas with v6 3100 engine. engine runs great at idle and lots of power when cold. after driving for 150 miles car starts cutting out and loosing power under load. still idling great at that...

could be a fault with the fuel pump. it may be wearing out. check the fuel pressure at delivery. a blocked filter can also do this as its being surged for more fuel not the normal filter this one is on the pump it has larger holes and if you have sludge in the tank this can stop the fuel delivery. . for vacuum leaks spray some carb cleaner around the air lines any change in the engine usually indicates an air leak. also the fuel pressure valve these can all lower or stop fuel pressure.

How do i rebuit my motor

You'll need to remove the motor, disassemble the engine, take the engine parts to a machine shop and have them check the heads, block, pistons and rods, crankshaft, camshaft and lifters. They should be able to give you a parts list of what you need to replace.

Rebuilt my motor and installed itin the car but wont run

Check for Gas...Check your Timing...You say you rebuit it..was it just the top end, or the whole motor ? I asked, because there is more things to list, but i wont go into too much detail because you might have done most of them anyway..And also check your compression....Goodluck...

Engine rebuit. Idle has Heavy putt-putting,

You may have the mechanical timing (ie, timing belt) off by a tooth. The engine will run that way, but not all that efficiently. That'd be my first suspicion. To fix it, it'll have to be torn down to where the timing belt is visible, as are the cam and crank sprockets and oil pump housing. Then the timing marks can be aligned to see if they all line up as they should.

1985 Ford Crown Vic engine when hot outside last 2 years would take time to start as I waited to re-try until it did. Lately has to have a jump and starts right away. Shop replaced: battery, serpentine...

It sounds like you have the wrong thermostat installed in your car. You need to get the water to the block quicker then what it's doing now. Always check oil every time before driving. This is a must on older cars. Some Mechanics differ, but in the long run it will pay off. An oil spot beneith the car might be bolts that need to be tighten on the oil pan, of you may have a bad oil sending unit. Also ehck power steering pump fluid level and make sure there is not a leak there.

Noise in motor

The 360 has a timing chain not belt, dont believe thats ur problem. Could be piston slap or wrist pin bearings. Before going to all that trouble I would check the flywheel if it has a small fracture it will cause a similar noise, often misdiagnosed as being low end engine problems.
