A compression test is the only sure way. Remove the spark plugs. open the throttle or have some one depress the gas pedal to the floor, fit a compression gauge to number one cylinder , spin the motor over till the gauge no longer riser any higher, make a note of the pressure , repeat for the rest of the cylinders , now put 5ml of oil into number one cylinder and take and record the pressure .repeat for all cylinders . On the first test all cylinders should be within 10% of each other, If one cylinder is very low it may be a valve problem , if on the second test the low cylinder tests ok it is a ring problem. find the compression for the type of engine being worked on in the workshop manual. check against the recorded pressures if lower than 15% recondition for best results.

You know when the rings are gone because its hard to start /loss of oil on dipstick/ black smoke when starting up and running /fumes from under the bonnet and loss of power.
Also could be your converter blocked.

Cylinder 3 misses and has carbon biuld up on plug also looks to have oil on the plug, smell like oil is burning , smokes alot out of tail pipe,oil consumtion is a qt, per 300 miles and it looks like oil is...


Geez!

U got a bad piston rings! U have to pull down the PiSTON to replace the PiSTON RiNGS, oil is getting in ur combustion!

Or

Check also the valve guide oil seal, hope that is the faulty one! 'Cause replacing PiSTON RiNGS will cost a LOT!


Check on that first, Oil in ur air filter means a BLOW BACK gas from ur combustion is pushing the oil into the air filter!

BLOW BACK is a residual combustion air that should have been burned or gone thru the exhaust, but w/ poor seal of ur piston ring, it goes into ur CRANK CASE and into ur EGR system w/ excess oil!

Hope that explains everything!

No compression on #4 cylinder on a 84 Mazda 2.0L Where is the exhaust going? What part do I need to fix it? Thank You!


If there is a COMPRESSiON leak in ur cylinder, either ur intake valve or exhaust valve is open during compression! First check ur gap settings of push rod or valve CLEARANCE using FEELER GAUGE. Check also ur BLOW BACK gas by opening ur OiL CAP, and run the engine, too much air from that oil inlet means ur PiSTON RiNGS are busted. Finally, sometimes SPARK PLUG are LOOSE or threads are gone and gas scapes thru that area! Hope that might help u out!

Squeaky belt and battery light on now


+++ been told to fix blue smoke...piston rings gone .

Piston rings, valve seals are a good guess for cause of blue smoke. Engin oil additives for high-mileage engines can help the blue smoke problem... Pep Boys and the like -- many different products -- just make sure it's for stopping smoke, not cleaning engines...

+++ squealin....fan belt gone.

Has the alternator belt been tightened? If not, this could be causing both symptoms: dead battery & squealing

+++ battery light on...alternator gone.

Again, this could just be a loose belt, and most likely is the problem...

How do you know if a piston ring has gone on a Ford Puma?


You cannot see a broken piston ring without taking the engine apart. If there is a broken piston ring you may or may not hear or see any evidence of it. If the piston itself is broken you will hear, see and maybe smell it with burning oil.

Water leaking from spark plugh


Hello;
Water / coolant coming from a spark plug hole is not good. However since you have a rotary engine, the probale cause is an o-ring that has gone bad. The older rotary engines were notorious for the o-rings going out. The o-rings seal the combustion, oil and coolant passages. The engine will need to be resealed. Hope this helps.
Thanks;
