Oil change mechanic said he couldn't get the oil plug back in and would have to replace the oil pan

Many States have laws against auto repair shops doing work prior to obtaining written authorization. You should check with your states dept of motor vehicles. You may be right that the mechanic, and I'm using the term loosely, stripped the oil plug. However, sometimes the plug get stripped by it being removed and replaced many times because of oil changes. Be that as it may, there are repair systems far less expensive than changing the oil pan. You are being SCAMMED! I've worked as an auto technician for 35 years and I'll tell you that there is not nut that broke in the oil pan other than the one that holds the oil plug in. They broke it forcing the cross threaded plug. Don't pay them, if you do, report them to DMV. It is better than taking them to court. What state do you live in?

Chevy cavalier 1998 2.2l Engines shake and when change to speed, it goes off

Carlos it sounds to me like your running with a dead cylinder. I want you to test for spark on all four of your plugs one at a time. You can buy a spark tester at most auto parts stores or just use a small diameter but long screw driver. With the engine off key off pull a plug wire off and insert the plug end of tester into the wire boot or stick the end of the screw driver in and attach the clip on tester to engine block or hold the shaft of the screw driver an 8th of an inch from the block an have a helper crank the motor ( be sure to keep all lose clothing and items away from moving parts) if you see spark jump the gap it's good. You can also remove the spark plug stick it back in the wire boot and holding the boot hold the threaded end of plug against the block. And watch the electrode for blue spark. I'm thinking you have a bad coil.

Engine light on. #2 cylinder misfire. runs rough

If its a dead skip its probably the coil..But first inspect the plug and the wire,,and make sure nothings burnt..DONT remove the plug while the engine is hot,,you can remove the threads..You can go to advance and buy a 3 dollar spark tester and take a sparkplug wire ,,hook it to #2 on the coil pack,,Ground the spark plug tester,,and see if the tester fires..If it does it will be something else..#2 cylinder is on the hard side against the firewall,,if you check the plug and wire

How to change spark plugs and wires

Joe s anwers is good and I can add a step to give greater access . Place car in nuetral with wheels at rear of car loosely blocked { 1 - 2 inches before tire hits front block } . Then acquire 2 ton Logistic strap { used by trucking / moving vans to strap items in place - hooks on each end with ractheting device to tighten up } Place car in Nuetral and Hook one end to front of motor eye / bracket for engine removal - Now hook other end to Radiator crossmember support { near washer bottle works } . Tighten rachet mechanism handle and watch engine get pulled forward allowing you 2 inches more of firewall access to get plugs out . Car must be in Nuetral for above -Then Caution Fully Block Wheels in case Strap lets go while working against firewall .

I paid yesterday for my question i recieved about the 1987 dodge aries 2.2 motor k series didt recieve an answer? the car cranks up but dost start

Check to see if it's fire or fuel. Take one spark plug wire off and put on spare new plug, Place spark plug on engine where the tip is grounded against block and while someone trys to start car check to see if there is spark arcking between tip and insulator on plug. it,s best to do this in the dark. if it sparks, try putting a little gas in intake then try to start if it starts or trys to start, yo know it's a fuel problem. Change fuel filter first, f no change check fuel pump. If no spark check ballast resister on firewall or fender

Where are the spark plugs in a 1999 Toyota Carolla and how do I replace them?

  • 1. Remove the two 10 mm cap nuts on the top plastic housing over the engine
  • 2. Remove the two fasteners on the back of the housing and remove the plastic cover
  • 3. You will see four plastic blocks with four wire clips on each block. These blocks are individual coils for each spark plug.
  • 4. Use the small flat bladed screwdriver to carefully lift up on the tab that holds the electrical connector onto the block and slide the wire clip off the block.
  • 5. Remove the 10 mm bolt that holds the plastic block onto the engine. Use the needle pliers to firmly grasp the plastic screw and pull straight up to remove it 
  • 6. Loosen the 10 mm nut on end of the plastic rail that holds the wiring harness for the blocks so that the round plastic washer on the bottom of the block will not break when you pull off the block
  • 7. Carefully pull the plastic block out of the engine. There is a 4 inch tube attached to the block that extends into the engine to the spark plug. It will take some twisting and pulling but you must be careful not to catch the back part of the round plastic washer that you cannot see, on the bottom of the plastic wiring harness.
  • 8. The spark plug is at the bottom of the 4 inch hole.
  • 9. Use a 5/8 spark plug socket with a rubber collar on the 3/8" extension to remove the spark plug. The rubber collar will hold onto the spark plug as it is removed.
  • 10. The NGK website recommends making sure the spark plugs have the correct gap .044 but the spark plug box says not to adjust the gap because you might damage the needle point iridium tip. The new spark plug has a protective cardboard tube that is removed.
  • 11. Spark plugs can stick inside aluminum heads and break off when you try remove them, leaving only the threads of the plug inside the engine which will necessitate removing the head to remove broken spark plug. Putting antisiez on the threads of the new spark plug will prevent that in future spark plug changes
  • 12. Now comes an interesting choice. You can use the rubber tube over the neck of the spark plug to slowly drop it down the hole and hand tighten it or you can use the spark plug socket with the rubber collar. If you use the spark plug socket, the rubber collar will stick to the plug and you will pull off the extension, leaving the socket in the hole. A pair of long needle nose pliers will reach into the hole and remove the socket, but the rubber collar may remain on the plug and you will have to bend a piece of coat hanger with a short 90 degree tip to reach into the hole and pull out the rubber collar. The rubber collar is there to prevent you from cocking a regular 5/8" deep socket at an angle which will break off the neck of the spark plug, necessitating another 10 dollars and another trip to the auto parts store.
  • 13. After the spark plug is hand tight, give it 1/2 turn more.
  • 14. Replace the square block, being sure that the black silicone gasket on the bottom of the round plastic washer does not get bound up on the engine post where the 10 mm bolt goes. Tighten the bolt
  • 15. replace the electrical clip.
  • 16. Go to the next spark plug and repeat the procedure.
  • 17. After the last spark plug is done, be sure to re-tighten the 10 mm nut on the wiring harness rail
  • 18. Replace the plastic cover over the engine and you are done.
Good luck and hope this helps.

Loosing spark plug

Very, very difficult re-threading an engine block. Not impossible, but very difficult and not usually performed by the DIY. That said take one of your spark plugs down to your nearest hardware store, one that sells loose nuts & bolts. Try screwing the spark plug into nuts of the proper size until you "match" the thread pattern. Do be afraid to ask for assistance from one of the experienced clerks (its free). The matching thread pattern on the nut will tell you the proper thread size. There are at least a couple different thread sizes and patterns. You may or may not be able to get th tool to clean the threads at the same location. My guess is that they will have the smaller sizes, and you may need to find a more specialized store to find the larger size tools.

Spark plug nut broke off and ceramic came completly out leaving threads and ring stuck in block plugs sets roughly 8 in into head. its is a 98 breeze 2.4 any ideas on getting it out

Yes.....use a good spiral extractor and lots of patience. DO NOT spray penetrating oil into spark plug hole. And don't run the engine to "get it hot" hoping the heat will help loosen it. It will NOT work. A quality reverse spiral extractor and a breaker bar WILL do the trick if patience is used.
