Remove the spark plugs. Using a screw in compression tester, screw the tester into a plug hole and tighten it slightly. Open the throttle and crank the engine about six full revolutions. Record the reading and proceed to the next plug. Do the same on all the plugs, recording the readings and cylinder number each time. That is all there is to it. If you can only obtain a press in type compression tester it becomes a two man job as one person has to hold the tester while the other holds the throttle open and cranks the engine.

Low compression in all cylinders on a 98 toyota corolla


all 4 cylinders are at 50 psi?did you remove all of the spark plugs to do a compression test?do you have a quality compression gauge ?do you have the right fitting installed in the spark plug hole, and is it tight?
if so. your next step is to preform a cylinder leak down test. you will need an air compressor to so so.one of the best things about your toyota is that it is a non interference engine. which means if the timing belt jumped, you wont damage any valves. be sure to check you timing marks before you decide to just junk the car.you could have some bad valves, or just need new rings!definetly keep searching before you junk the car!start by checking the timing, and then do the leak down test.

I HAVE A 1994 YAMAHA VIRAGO 1100 MY PROBLEM IS I HAVE NO COMPRESSION ON REAR CYLINDER.


No compression can be a few different things, from a bad valve, a broken valve, or bad piston rings. You are going to need to preform a leak down test to figure out what is going on and what is causing the loss of compression in the cylinder.

2.If that don't work switch your coils. (remove one of your other coils and switch it with the #3 coil. If the misfire moves to the other cylinder then you know you have a bad coil and it need to be replaced.

4 Also check your fuel pressure.

Run a compression test, alot of times the engine overheats and blows the headgasket, once the spark plugs are removed watch the holes and see if antifreeze shoots out of them while preforming the compression test. More than likey this is the problem. The head can be removed and pressure checked to ensure it has no cracks and then it will need to be resurfaced prior to reinstallation. Hope this helps, let me know.

It lacks power and pops out the intake after it is warmed up. it has all new tune up except the coil. i just replaced the fuel pump, fuel filter, fuel lines and all exhaust leaks. it is a 318 magnum


If it is backfiring up through the intake manifold then you have one of two problems, either your ignition timing is to far advanced ot you have a burned or damaged intake valve not seating at point of combustion. you say it lacks power it could be for several reasons, to diagnose and not guess is the best policy, preform a wet and dry compression test and or a cylinder pressure leak down test, this will tell you the internal mechanical condition of your engine, it will tell you the condition of the Rings, and Valves in each cylinder and a leak down test will tell you the percentage of leakage in each cylinder as well. I would look first to your Ignition timing and also check if you removed you distributor that it was put back in it's proper location then after that preform the above mentioned diagnostic tests...
