Oil leak? pan or valve cover? placed cardboard template under oil pan-shows oil all over area template?

1 a simple compression test will tell you if the rings and valves are bad. thats where you start.. 2 it could be an oil leak under the vehicle , you will see a black spot. do this first it only takes a look whee you park it on dry clean pavement or place a clean piece of cardboard under it.

Mike: Oil leaks are pretty common on the Odyssey...Place a piece of cardboard under the vehicle to locate the leak...Oil pan and,valve cover gaskets are common points on your vehicle...If the leak is Brownish in color it's probably the side motor mount...send a comment...Guru...saailer

oil leaks can come from many things.like front timing cover crankshaft seal, rear main oil seal,with engine running look under car around oil pan area check see if you see heavy oil leak which will come from loose or damage oil filter and seal or check oil pressure sending unit at bottom right rear engine block or right rear corner of the oil pump.if oil leak small leak the front crankshaft seal and rear main seal leaking .

the best way to locate the oil leak, if you can't see where it is coming from is to park the car overnight , and put a large piece of cardboard under the engine, so where the oil leak is, it will drop onto the cardboard, then the next day, look under the car, and see where the oil is on the cardborad, the leak should be in the area of where it is on the cardboard. also, the leaks could be anything from the oil pan gasket, oil sending unit, valve covers, intake manifold gasket. or the rear main seal. hope that this information was very helpful to you.

You cannot repair the leak until you determine where it is leaking. More than likely it is leaking from the oil filter, oil pressure sending unit, or valve cover gasket. Check around the oil filter for a leaks and if you see oil on the filter then replace it. Check the oil pressure sending unit and if it is leaking replace it. Wipe all the oil off the bottom of the engine and any other place you see oil. Now place newspapers on the floor under the car and then start the engine and let it run for about 10 minutes and then shut down. Wait overnight and you can see where the leak is coming from.

To locate the leak , place a piece of cardboard or newspaper under the car over night and check in the morning and it should show an approx area where the leak is coming from, check / top up your oil level then take the car and the cardboard to a mechanic it will help them see where the leak is..

Clean all the area and check again; maybe the seal need one new adjust or the oil pan cap too.

Hello Mark.
The next most common thing I would look into here is the oil pressure sensor. They sometimes pull apart and leak at the seam.
Your 2 liter engine has it's sensor on the top left side of the cylinder head.
If the concentration of oil seems to be on the top side of the engine a valve cover gasket may have cracked.
A severe leak will often wash dirt off of an engine so look for an oil washed area. If nothing apparent it may be a good idea to give your engine a quick cleanup to help you find the leak as oil can travel a long way on an engine.
Hope you find the source OK.
Thank you for using FixYa!

Northstar engine, that's about right. They do take about 8 quarts.
The most common place they leak at is at the oil filter housing that attaches to the block of the engine.

first thing first... have you seen an actual oil spot/leak on the ground after the car has sat overnight. have you checked the seal around the oil filter.
If you have done those things and both are no... there is a chance it is burning the oil... what does the exhaust smoke look like ?
