The oil is most likely leaking from the oil cooler seal. The oil cooler is the square aluminum piece that the oil filter screws onto. To replace the seal, remove the filter, remove both coolant hoses that attach to the cooler, remove the nut that secures the cooler to the block and slide the cooler off the tube. Replace the rubber o-ring seal which is available at the VW dealer. It's inexpensive. Replace everything in reverse order. Good luck

Massive oil leak suddenly on 2000 vw beetle looks as though came above oil filter and awhinning pumpsound present


That's the oil filter cooler seal. My car did the same thing; poured a quart of oil out on the ground in about a minute while I was looking for the source of the leak.

There's a box with radiator fluid going through it mounted between the oil filter and the block to cool the oil. It's got a large o-ring to seal it, and when that seal goes, it just *pours* oil out. Take the oil filter off and you'll see a large nut. take off the nut and the cooler will slide off - you can do that without removing the fluid lines.

The seal is between the block and the cooler and will be very obvious when it's bad; mine was missing a big chunk out of one side. Popped a new seal in, put it back together and haven't had a problem with it since.

It seems that you have a bad oil filter adapter seal. You can usually pick one up at your local parts store, if not, they may have to order it. To change the seal you must first remove the lines close to block and the you shoul be able to unscrew the oil cooler adapter from the block, may require an allen wrench to loosen. Then you should replace the seal or gasket inbetween the block and the cooler adapter and then reinstall the adapter, reconnect the lines. Be sure to catch the oil in a clean container so you can reuse it to pour back into the block, check the oil level and if at a safe range start the vehicle and check for leaks. If no leaks you should be ready to drive at will.

What causes the oil filter housing to leak - it is above the filter - we replaced the filter but this is on seam about 1/2 inch above the top of the filter


If there is a spacer between the oil filter and the engine block then you would could have a bad seal on it. If its similar to a Honda there will be to hoses going to the spacer. This spacer is called the oil cooler adapter. If this is it. Take oil filter off and the remove the oil cooler nut if there is enough room you won't need to disconnect cooling lines. Pry the Adapter away from the block with screw driver. remove old seal clean surface with clean rag install new seal. Wipe a little oil around the seal just like you would the oil filter. 'Tighten snug, but don't over tighten. Not sure the correct torque for this. Hope this helps you. This similar problem occurred on my 1995 Honda Odyssey.

Win i start the car and look under the hood, there is oil coming out of a box that is, on the side of the block. But above the oil filter ?? . How do i fix that, is it a gasket or what ??


That is the engine oil cooler. There is a 'O' ring between it and the oil filter mount. They harden and crack.

Ask your dealer for the large Oil Cooler 'O' Ring.

Remove oil filter. Remove exposed pipe nut holding oil cooler to housing. If nessacary, drain coolant so you can disconnect coolant hoses from cooler or catch coolant as hoses disconnected. Swing oil cooler away and remove old 'O' ring.

Place new 'O' ring with grease on oil cooler it to hold it in place and reassemble. Tighten oil filter pipe nut to around 18 ft lbs .

Refit oil filter. Refit coolant hoses and top of oil and coolant.
Run engine to check for leaks and allow to cool. Top of coolant to COLD level if required.

You will need hose clamp pliers and wrench for oil cooler pipe nut. Pliers can be obtained from most parts stores.

The Gasket between the Oil Cooler and the block has ruptured. This is right above the oil filter and can be gotten to by removing the filter, then removing the 30mm nut holding the cooler to the block. this is a special gasket so use the correct one.

The passenger right side of the car doesn't have any flanges for cooling system, if that's correct then your radiator has a leak or puncture.

The driver side of vehicle has both the in and out flanges for the radiator. Very common to see leak at the drain valve leaking (not closed tightly). In the same area would be bottom flange of radiator which the composite flange is degrading and causing the leak.

The middle part of the bottom engine compartment is where your oil/coolant cooler assembly just above the oil filter. A loose oil filter could be the cause 95% of the time and 5% would be a bad o-ring from the oil cooler to the oil filter flange.
