My cousin informed me that her car had been leaking oil through the oil filter. In two separate occasions the oil filter was replaced, but the oil leak continued. She had also mentioned that on a recent trip, the spark plug wires had lifted but I didn't really give it much thought.
I proceeded to check the spark plugs to see if it was burning any oil. As I started taking the sparkplug wires from the sparkplugs I noticed that oil had seeped into all the chambers, enough that clean the top of the spark plugs and the plugs. Next, I removed the spark plugs but these were all dry. Big sigh of relief; so I thought. I then installed new valve cover kit which included valve cover gasket and gasket around the sparkplugs to resolve that problem. Then, I moved on to change the oil and oil filter; the oil filter was firmly tightened. The engine was started and I immediately noticed oil leaking from the oil filter. Next, I proceeded to remove the oil cap and noticed that lots of air was coming out of the oil filler hole - this didn't look good. At this time I was perplexed as to what could be causing this problem, bad piston ring or PVC valve; I turned the engine off. By this time all auto parts were closed, so as a temporary measure I decided to remove the oil filter and put a bead of red (hi-temp) silicone gasket maker around the oil filter base and placed the filter back. I turned the engine on and leaking continued.
Do you have any suggestions? Compression test perhaps?

Hi f1ebru,

It is not the oil filter that is causing the leakage. The base of the oil filter is the oil cooler and behind it, there is an O ring which would leak when it goes bad over the years.

Remove the oil filter, loosen the central nut (27 or 30 mm) pull out the shaft and you can pry the base out slightly to replace the O ring. Do not pull too hard or you would damage the coolant hoses. If the oil cooler hoses are bad, it would be good to replace them.

Blowby escaping from the oil filler cap is normal for engines of the age and mileage clocked.

Thank you for the reply, I will try your suggestion.

A have one more question, if the blowby preasure builds up, would it be possble that oil can seep through the rubber grommets around the Spark plugs?

Sincerely,
AC

If the plug seals are good, they should not but if the seals are worn, they would allow oil to leak through. If after replacing the plug seals and the problem persists, you would need to replace the O rings under the cam carriers, they are prone to leaks.

I have a 1997 Accord I-4 with 180k miles (manual transmission). When attempting to get out of a snow covered driveway, the vehicle spun out a few time. After removing the vehicle, observed two small oil slicks on the driveway where it had been sitting. Looked underneath the car and observed some fresh oil underneath the transmission housing. The car recently had its 180k service. Any thoughts as to what is causing the leak? Thanks

By the symptoms you describe there's a good possibility the leak could be either the rear main seal or more than likely the oil pan gasket at the back of the motor. Get under the vehicle and look to see the exact area. The cheaper way is replacing the oil pan gasket. If it still leaks look into the rear main. Hope the info helps

I am wondering if the movement of the wheels being stuck and forced in to extreme pressure may possibly have let out some tranny grease where the CV axles enter the tranny. The oil of the engine and the oil of the tranny have two seperate distinctive odors and the oil for the tranny is much thicker. Watch the vehicle and see if the location manifests itself or goes away.

We have looked everywhere for an oil leak on this car and also changed the oil pan gasket and the valve cover gasket. The oil seems to be pouring out of the side of the timing belt cover behind the mounting brackets of the alternator. It starts coming out when the engine is running. I dont think that the oil should be coming out of the cover but it does have a crack in it and it is the only thing we can see. Is there a freeze plug or something behind that bracket that could have gone bad? Before I start tearing the brackets off I wanted to see if anyone has had the same issue. The car didnt leak any oil prior to this happening. Any advise would be great.

Hi there,

It sounds like the oil is coming from the cam seals, if it is as bad as you say, it should be easy to see, also the timing belt should be replaced if it is contaminated with oil.

Thanks for advice. I just went ahead and got a whole kit to do the water pump, cam seals, crank seals and new pulley assembly for the timing belt. And also a new timing belt. Not very expensive but time consuming. ( Both the cranks and the cam seals were bad.) Thanks again

I took my car in for my usual oil change & the mechanic said I only had 1 quart of oil left in the engine & I had a severe oil leak. He said that it would cost over $700 to fix because he had to reseal x, y, & z, install a new oil pan, etc. What exactly must be done to stop an oil leak & Why is it so costly & is there any other cheaper solutions to repair this oil leak?

If he is saying that the oil pan is leaking, then it could be removed and new gasket or sealer installed.

Depends on what else is leaking, front seal, valve cover gasket etc.

Key is that if you only had one quart of oil, then you are at risk for major engine damage.

Get a second opinion and ask for specific parts/gaskets that need to be changed.

I noticed my car temp was running hot and then my oil light came on. When I turned the car off the engine was smoking a bit. I put 4 quarts of oil in, then two days later my oil light came back on and my engine was smoking again with a smell of over heated metal. How should I got about finding the oil leak, should I use a tracer dye. Or does it sound like something else is wrong. Thanks for any help!

Hi there,

If you have a bad oil leak, you should only need to give the engine a good all over wash down and go for a drive, you should soon see the oil starting to leak, do this first.

What does it mean if a mechanic says there's oil leaking inside the engine?

It means you are internally burning oil in your combustion chamber. Oil is seeping past either your piston rings or your valve seals and burning burnt in the combustion stroke.

My 96 honda accord has been leaking oil for about 6 months. I have just been adding oil til I saved up some money for repair. A friend finally cleaned the entire engine to better see where it was leaking oil. When I took it to the shop the mechanic said I needed a pcv valve because it was clogged and he said I needed a "variable timing pressure valve" that cost $225 (part only). You could see oil shooting up on the inside hood of car. He quoted me a final price of roughly $380. Plus he had to add several quarts of oil. I have been trying to research that part & price but I cant find it anywhere. He showed me the part and everything.I just don't want to get taken advantage of because I'm a woman. Have you ever heard of a variable timing pressure valve & is that repair price about right?

Are you sure he didn't mention the "Variable Timing Solenoid" b/c that part IS indeed $250, roughly.

EDIT> One frustration of the auto industry is everyone wants to call a part by a different name. Case in point: Check Engine Light. GM calls it an SES (Service Engine Soon light) and some call the "idiot lights", and I'm sure there's more names for it.

Did he meant VTEC solenoid valve? There's no variable timing pressure valve on the 96 Accords. Got a picture of the leaking oil?
