If somebody changed oil on a 1997 Honda accord coupe is there a possiblity they can damage the oil pan gasket?

i own a 97 honda accord make sure right oil filter clean all around oil pan clean around oil filter if you got it up on floor jacks start it up look for leaks and check valve cover gasket i don,t think it would be head gasket.

Yes there is. if it leaks, find out where. You may have engine damage from running the car out of oil. You say it leaks from the oil pump, same as before? was the oil pump replaced? Sounds like a pressure fed leak, so it should be easy to find.

Get under the car and locate the oil pan near the front of the vehicle . Put a drain pan within easy reach. Use a socket wrench to remove the nut that holds the oil pan to the car. Hold the pan with your other hand so it won't drop when the nut is removed.

Slide the drain pan quickly under the oil pan to catch the old oil. Drain as much as possible.

Remove the old oil pan gasket very carefully with a thin paint scraper, and then wipe the surface with engine cleaner or solvent.

Rub a bit of oil on the sealing surface to promote adhesion, and attach the new gasket securely. Reattach the oil pan to the car with the bolt.

Pour fresh oil into the crankcase. Honda Accord cars will require between 5 and 6 qt., so fill it until the crankcase looks full, and then check it with the dipstick to be sure, adding more if necessary. Back the car off the ramps.

Put the old oil in a used milk carton and attach the lid securely. Take the oil to a hazardous materials disposal facility, or to a garage.

Not too hard, just need to drop the front exhaust pipe first.

you need a new intakemanifold gasket, and oil pan gasket, and the filler neck for the gas. all easy repairs. but the grinding noise? make sure you replaced the rear brakes if equiped or drums if not.

have car jacked up and blocked for safety,drain oil from engine and remove the oil pan bolts,remove pan.

Worn gasket seal around pan, worn or loose oil plug, pin hole in pan, someone forgot to put back the oil cap are some suggestions that come to mind.

Replace oil pan gasket, make sure not coming from behind timing belt cover first.

loosen all bolts. the pan should drop if not tap it a little. place the gasket sealant on new pan and then right away put the pan on the block before dries, and tighten all bolts in a scarterred pattern

When you say fluid ... I assume you talking about the oil and oil filter.
If you changing oil here are the steps :
1> Jack up the car, make sure you do not put the jack on the oil pan as it is most likely it will damage the oil pan.. rather put it on the frame which is little bit to the left of the oil pan. Trace the bolt to the rear of the oil pan.. I believe it is a 17mm bolt. Place the oil pan under the bolt and take the bolt off. Almost all your oil will drain out here. Make sure the oil cap on top of the valve cover is taken off.
2> About 10 inches to the top of the oil pan bolt .. you will find the oil filter. Usually you should be able to remove it with your hand, rotating it in an anticlockwise direction. The rest of the oil will drain out here.. so adjust the oil catcher pan accordingly.
3> Take the new oil filter and apply some of the old oil on the rubber gasket of the oil filter and tighten it back up in clock wise direction.
4>Tighten the bolt to the oil pan and lower the car from the jack or jack stand for easier access.
5> Put in 4 quarts of 5W30 or 10 W 40 through the oil cap on the valve cover.
6> Wait a few minutes and pull the car back a few feet. Check for leaks and you should be good to go.
