What was the first thing that went wrong? Sounds to me like a valve stem is letting oil by it. When you say full of oil you dont mean clear full do you? Easiest way to test this is with a cylinder leak down test

Your valves in the cylinder head are not seating all the way or your piston rings are bad does the car smoke when it's running?

Are you getting spark from coil wire when cranking? If so, check the cap & rotor. If not, the most common failure is the crank sensor. If you have a 4,0, you can find it on the drivers side of the bellhousing, in line with the flywheel, just where it's annoying to work on. There is a test you can make, but I don't have the specific test values or the correct terminals to check. (you can find that info in any half decent manual.
Good luck

If it ran good prior to spark plug replacement, then yes, I'd be looking real close at the plug wire to that particular spark plug. Perhaps it pulled apart inside boot upon removal. It may even be an indication that they are all getting weak, and time to think about a new set if it's originals.

With a service engine light blinking...don't drive it.

When replacing the spark plugs, double check that the boots on the coils are installed correctly. Check these again, and make sure to either listen for or feel a little click which tells you it's properly seated on the top of the spark plug. This is a common thing, happens all the time to people with TB's and Envoys. I've even done this myself.

In case you didn't know, # 1 cylinder is up front near the fan, then it runs in order to #6 at the firewall. Possibility....(don't take this as doubting you), maybe the wrong coil was replaced and one or more coil boots weren't set properly? Some things to check anyway.

I have 1987 oldsmobil engine 6 , the rings are stock cuz it was siting for long time what the best way fix it


Pull the spark plugs out and pour cutting oil in like "Marvel Mystery Oil" or WD40 (about 4 ounces) into each cylinder, let it set for a few days and try to crank it over with the spark plugs out, if it cranks blow all the oil out of the cylinders, install fresh spark plugs and pray.

I need to know if you did'nt oil the pistons and piston rings or prime the motor do i need to pull it out and do it


Pete, did you do a complete engine reassembly with out lubricant.
If you did, you could have real problems, especially with crank and rod bearings.
Pistons and rings could be oiled through spark plug holes, 1/2 oz. in each cylinder, take cylinder to bottom of stroke, then give a blast of compressed air to help distribute oil in each cylinder and then rotate engine a few times to complete oil distribution.
To pre oil crank and cam and bearings, you could over fill engine with new oil until you feel it is flooding(above) cam then let soak over night, then rotate crank shaft 20-30 times to distribute oil.
Drain oil, and refill to correct spec's.

Rad hose blew gauge went to red pulled over spuddered then stalled tried to start cranks kinda slow


Engine may be tight because oil has fried and deposits are on cylinder walls. Might have even broken some rings, but try changing oil, pull all plugs and add 1 teaspoon new oil to each cylinder. Crank with plugs still out for a few seconds, reinstall plugs and try to start. Good luck.

Have 95 tracker. Front cylinder has spark injector clicks when turn to on. pull injector wire runs same, pull plug wire runs same? what should i do next?


spark injector? no such An-i-mule.

the G16B (KV) engine, is it? has 4 spark plugs
and 4 fuel injectors.??
so you pulled what?
you have a dead cylinder, if you check the heat on the front
exhaust header tube, it will be cold or way colder ,using any pyro gun.
which engine,
http://www.fixkick.com/sensors/8v16v.JPG
see them here, ?
http://www.fixkick.com/sensors/16v-engine93w.jpg

whats next that is easy its called a compression gauge.
i must guess engine, do the top valve cover on the engine shout
16 valves?
if yes, make sure the spark wells (deep pits) are not full of oil
or water. if full of oil, the last owner never check valve lash
at 60k miles and replace the valve cover gasket (set)
or if water someone used pressure washer on the engine (bad)

the full compression test is here.

Piston hitting valve


The procedure is ti fit the timing belt properly. Did you start the process with the engine at TopDeadCenter on the compression stroke of number 1 cylinder? Something is terribly wrong, congratulations on testing the configuration by hand. I've seen what damage has been done by people that just hooked up the battery and wind it over. They had a smashing good time.

Pull all your spark plugs, put your finger over the number 1 spark plug hole and wind the engine over by until you find the compression stroke on number 1 cylinder. Keep turning slowly until you bring you crank timing mark to the timing indicator. You should be at TDC compression number 1 cylinder, you can check with a screw driver or piece of wire that the piston is at the top. Make sure you are winding the engine in its working direction. Now look at your camshaft timing marks and indicators, they should all line up. If the marks are out of line, correct them, do not move the crank.

Once you have everything lined up again and tensioned correctly. Turn over the engine by hand 2 FULL revolutions. Should be all good then.

95 saturn gas on the spark plugs


It is normal for them to show gas-continued cranking of the engine keeps putting more gas in the cylinders.
Oil is getting in there from worn engine parts-piston rings or worn valve guides or valve stem seals. If enough oil gets on the plug, it will inhibit sparking- known as "oil fouling". Oil fouled plugs can be cleaned and reused. The near-prohibitive cost of repairing the worn engine parts with an engine rebuild may make you want to remove the plugs and clean them as often as necessary to keep them from misfiring. However, if it is just worn valve stem seals on those two cylinders, a shop could replace the seals without having to take the cylinder head off. The cost for that job would be some less. You might want an estimate on that. The seals are a rubber composite and quite cheap. A little tricky, but it can be done without pulling the head off.
Now that you have cleaned those two plugs and put them all back in, the gas will have evaporated. So if it does not want to start, you need to check for spark to verify the ignition system is working. The easiest way and to avoid a shock is to buy a cheap spark tester, pull off a plug wire from a plug and hook to tester. The tester is then clipped to a metal bracket or bolt as a ground. Then have someone crank the engine over, while you watch the tester for a spark-a strong blue spark, not yellow or orange, will verify ignition system is good. If no spark exists, test all cylinders. One or two with no spark could be a bad coil on the coil pack. But if no spark on any, the ignition system will have to be diagnosed. Good luck./

Lancer timing


-Try one more time. When pull out the plug, make sure ground it.
If there is spark shown. It could be the rotor point to the wrong cylinder plug wire.

Error code reads #4 cylinder misfire??? possible probs & fixes


I'm assuming your trouble code is P0304 and you have the 5 cylinder engine.
take out the spark plug, does it look normal? No foreign materials on it, like coolant or oil? If it has coolant on it, you have a blown head gasket.

If plug looks ok, put the wire back on the end of it, pull the wires off the other plugs, hold the #4 plug with wire up against the engine to ground the plug threads. Have someone crank the engine while you look for a spark. If no spark, try putting the plug into another wire. If still no spark, plug is bad. If it sparks in another wire, wire #4 or coil #4 is bad. In this last case, you can swap wires with another coil to determine if it's the wire or the coil that is bad.

If #4 plug sparked in wire #4, ignition is working and problem is with the cylinder. Run a compression test on all cylinders. You can borrow or rent the tester. Take all plugs out and screw the tester into each plug hole one at a time. Crank the engine a few revolutions and read the gage. Write down the pressure, release it from the gage and go on to the next cylinder. If #4 comes up short, you have a burned exhaust valve or blown head gasket.

Please let me know if you have any questions or need more instructions.

Whats the correct way 2 perform a compression test on a chevy v8 small block


FIRST OF ALL YOU NEED TO RUN ENGINE FEW MINUTES DONT GET IT TOO HOT. TURN OFF ENGINE. THEN PUT ON SAFETY GLASSES. USE COMPRESS AIR BLOW DEBRI AWAY FROM SPARKS PLUGS.TO KEEP FROM GETTING INTO CYLINDERS.DISABLE YOUR SPARK IGNITION.AND DISABLE FUEL PUMP.BY REMOVING FUSE.NUMBER AND TAG SPARK PLUG WIRES.REMOVE ALL PLUG WIRES AND SPARK PLUGS.BESURE YOU NUMBER THEM AND TAG THEM SO THEY GO BACK IN THE ORIGINAL PLACE.THEN GET COMPRESSION GAUGE TESTER SCREW IT IN SPARK PLUG HOLE TO CYLINDER 1 FIRST.TAKE YOUR FOOT PRESS ACCELERATOR PEDAL TO FLOOR.PUT KEY IN IGNITION SWITCH CRANK ENGINE AROUND A FIVE TURNS.THEN CHECK COMPRESSION ON GAUGE.IT SHOULD BE NO LOWER THAN 100 PSI.IF SO SQUIRT SOME OIL IN THAT CYLINDER. IF COMPRESSION INCREASES.THAT CYLINDER HAS BAD RINGS IF OIL SQUIRT DONT INCREASE COMPRESSION. VALVES IS LEAKING. YOU DO ALL CYLINDER THE SAME.SCREW COMPRESSION IN PLUG HOLES.TURN ENGINE OVER 5 ROUNDS. WRITE DOWN ALL READINGS.

1984 380SL MB, Car was inactive for at list 12 years in a controlled environment. I installed a new battery and crank engine; did not start... As I was cranking oil presure registered at normal presure....


Apollo, I would first pull all the plugs out and give a little squirt of something like seafoam or even just a bit of engine oil into each cylinder, you may have lost the seal between the rings and cylinder walls and this will help. You also need to confim for shure that you are not getting fuel before you worry about the pump. You can check this at the fuel rail, either by opening up the line, or in some cases you may even have a schrader vale(like a tire valve) on the line that you can press. I suspect that you do have fuel, but the injectors are not oppening due to the old fuel sitting in them for so long. These can be removed and taken to a shop that cleans injectors, and then reinstalled with new seals. And yes I do belive that there is a fuel pump relay in the fuse area, you need to do a search to find out wich one. These can be jumpered to activate, but untill you have done everything else i wouldn't worry about it. Oh, I asume that you have checked for spark? If not, you can pull a plug out and with the wire attached you can hold the base of the plug against the block, while wearing gloves, and see if you get a spark when some one cranks it over. Remember, you must have spark, compression and fuel at the right time in the proper ammount, and it will run.
