Hey I have a 2002 coupe I had some modifiactions done. I had a new cam and new heads new intake. I also had a hi volume oil pump installed
besides other mods.
My problem is I have a oil leak on the passenger side of the engine. It only starts leaking at around 3000 RPM. It's in the lower part of the engine. The whole bottom half of the motor is covered in oil. I was wondering if anyone out there has had this problem. I'm thinking it might be the oil pan gasket but would it leak all the time even sitting still in the garage. I want to remind all of you it only leaks at high RPM 3000 OR MORE.
I doubt its the pan, the oil is probably leaking elsewhere and ending up on the pan. For cam and heads, I would suspect the front seal or possibly the timing cover. Like VinnyT asked, what is your pressure? You may also be pushing too much to the top of the motor. My first suspicion would be front seal though, look under the car near the crankshaft pulley, see if the area is wet.
I have looked at the front seal and timing cover gasket and it's bone dry.
The oil pressure if I remember correctly at 3000 rpm is around 45 to 50 psi. I will have to pay attention to this the next time I start the car. I never gave it a thought to be honest.
The leak seems to be towards the bottom end on the passenger side
towards the back of motor.
This has me stumped I looked to see if there is a sensor on that side of engine. I didn't see one on this side.
Hey once I get this problem fixed doe anyone including yourself have a sugesstion what to use to clean this oil off my under side. My stainless steel long tube headers have taken a beating and my hi flow cats. including my s/s magniflow exhaust. I have oil alll over the underside.

Two other suggestions. I believe the oil level sensor is in this location, is that dry? Also, sometimes the oil pressure sensor will leak and run down the motor along the back.
I want to update all of you on my oil leak it was the o ring on my dip stick. I can't believe the mess I have to clean up under neath from this little o ring. Hey any sugesstions as to a good solent that would especially clean my Stainless long tube headers they are a mess. My floor boards got a good oiling bath also and needless to say the tranny and the rest of the under carriage.
Once again I can always count on my friend here at the forum for help.
I've had very good luck cleaning oil from engines & tranny's using brake cleaning fluid with a straw extender. It sprays on precisely and drips to the newspaper pile underneath -- no wiping required.
This technique is especially useful when trying to ID a new leak. Once the area is cleaned, a short test drive will show the origin of the oil.

A large spray bottle of Simple Green works well and is easy to hose off after without damaging anything. Just don't let it sit too long before you remove.

Be careful using the simple green on aluminum..........good advice about not letting it set too long............personally, I'd go the spray brake clean route with lots of old newspapers on the floor below, to catch the mess. I've used brake clean with success to clean fender well areas as well, once wheels are removed........spray liberally, and then use old throw away rags to wipe clean. Repeat process if necessary to remove excess road tar etc.

One thing I like about Simple Green and some of the citrus-based products is that they are non-toxic and biodegradable.
