On my 1999 kia sephia the spark plug has oil on it what does it mean i was told it could be a piston ring How much would it cost to fix?
Are You Speaking Of More Than One Plug ? Is The Cylinder It Came From Misfiring ? It Is True You Could Have Bad Oil Rings On The Piston, Also Bad Valve Steam Oil Seals Will Cause This. And A Dead Plug Will Show Oil On It. If You Have Installed a New Set And It Runs OK. I Would Let It Ride. If You Need To Know More Have A Compression Check Ran On Your Engine. This Will Provide Some More Information On The Rings. Resubmit Question With More Information If Need Be Good Luck Also could be a leaking valve cover leaking oil into the spark plug galley.
What else can I help you with?
Why would spark plugs have oil on them?
Piston rings shot.
What would cause a spark plug on a 4 wheeler to continue to go bad?
the rings could be bad on your piston which causes oil to go into the head and mix with your fuel and burn up your spark plug
What would cause the P0308 DTC code on a F150 truck?
A variety of reasons, most common is a bad spark plug wire or coil pack but possibly a bad crank sensor, but could be a bad piston ring, scored piston chamber wall. a hole in the piston, etc Check the spark plug pocket to see if it is full of water.
The piston is hitting spark plug on 4 cylinder can the 1.3 samurai engine jump time?
Since the samaurai uses a timing belt it can jump but not in this case. Jumping time would not make it hit the spark plug it would come very close to the valves and hit those before it hit the spark plug. You may have a problem either with the piston rist pin or with the piston rod cap coming loose. Hope this helps To rephrase the question: If a piston in a 4 cylinder 1.3 samurai engine hits a spark plug could it cause the timing belt to jump time? If the rotating mass of the cam and valves versus the crankshaft has enough kinetic energy to overrun the timing belt, then yes, it is possible. It does seem very unlikely fundamentally because the mass of the piston would either flatten the spark plug or the piston would dent and if forced too far by the spark plug it would fail catastrophically and would have metal failure such as holes or cracks. In other words, it depends on how many RPM's the engine was running at, when it hit the spark plug.
What is the misfiring problem with my car after it overheated?
could be as simple as burnt spark plugs i would think it would run worse with a burnt piston but if its not smoking or anything the pistons should be fine so i would start with the plugs
What would cause a 98 Oldsmobile intrigue from starting?
no gas entering piston chambers or no spark in the spark plugs. I assume the starter is spinning the engine?
What would make the number one piston missfire?
Year, make, model and engine size would help, but a bad spark plug, spark plug wire or fuel injector are a few possibilities.
Would the computer cause no spark?
It could.It could.
Why would your radio clock and overhead light stop working in your 2001 Kia Sephia?
It could be a blown fuse.
Why won't a 4 hp Briggs and stratton rotertillar start has good spark has compression has good gas starting fluid did not help in piston nor air intake?
I assume you checked for spark by removing the spark plug wire and tested for spark against ground. Although you may have spark through the plug wire, the spark plug could be bad and the spark is not being conducted to ignite the gasoline - change the spark plug. Another reason would be a sheared keyway on the flywheel that would cause it to be out of time. Another possibility is a shorted kill switch wire. Hope this info helps.
Why would the 8th cylinder in a 1995 camaro z28 not work?
Bad spark plug or wire? Bad Valve or piston? (do a compression test)
What would make your gap close up on the spark plug of your 1986 Nissan truck?
Arcing or carbon build up. At a real stretch, the piston could actually have hit the plug. Probably gapped incorrectly when first installed.
