SOURCE: how do i fix the oil leak at the round block on

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.

My pickup has developed a leak between the block and the oil filter housing unit, not the filter. Is there a gasket that needs to be replaced?


I do believe that there is actually a gasket that is between the oil filter housing assembly and the engine block. If it is anything like the Nissans, they do have a tendancy to start leaking over time.

Hope this helps..

Need to know how to remove oil pan with engine still in vehicle on 96 Ford Wind Star 3.8 engine. What will I have to remove to get access to it.


3.8L Engine Fig. 2: Oil pan assembly - 3.8L engine 89693g43.gif

NOTE: When using silicone rubber sealer, assembly must occur within 15 minutes after sealer application. After this time, the sealer may start to harden and its sealing effectiveness may be reduced.

Oil leak above oil filter . Ther is a adapter. on a 1995 chvey 5.7 motor


There is a rubber o-ring between the oil filter adaptor and the engine block that needs replacement.
Disconnect the two oil cooler lines from the adaptor. remove oil filter. Two torx head bolts mount the adaptor to the block. rmove these and replace o-ring. Assemble in the reverse order of removal.

Oil and Coolant leak of about 11/2 quarts coolant - 1/2 quart oil per night Leak 1 (Coolant) Appears to be coming from the radiator bottom right corner. Leak 2 (oil) Appears to be coming from the engine...


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.

OIL LEAK COMING CLOSE TO THE OIL FILTER


if you had recently done or had an oil change done sometimes the gasket from the old oil filter sticks to the block. when you install the new oil filter it ends up with 2 gaskets and leaks around the base where filter meets oil cooler. another posability is the oil pressure sending unit is mounted just above the filter.

Oil leak near the oil filter and sending unit.


I am an "x" mechanic and had the same problem with my 94 jeep grand.

This is an adapter block that connects to you engine. The chrysler designer didn't leave enough room to put on an oil filter so the put a 90 deg bracket on to miss the frame.

At the end of this adapter you will see a ,large looking bolt with a star insert. This is called a torx.
I will have to look tonight but my memory is saying it is a 20x torx. The problem is the std torx socket is to long. 2-3" you only have 1-1/2" to get torx and ratchet between frame and adapter. I modified a std torx to be shorter. You insert into a 3/8 ratchet and put a small pipe on ratchet. This give more leverage. This torx bolt is very tight.

It is easer to remove from the bottom of car. Once it is loose you can remove oil filter first before doing or just leave oilf filter on the bracket. be shore to dump out oil before remounting bracket. There are two o'rings between engine and bracket. From the heat crack making the oil filter look like it is leaking. My engine starter was always wet with oil. After I replaced the o'rings it has never leaked again. I also saw oil leaking from my oil switch. I replaced it also. The chrysler dealer had the o'rings apprx $3.00. 1 large and one small for bolt I bought the oil sensor from Salvo's $15.00

Or you need to take to dealer.

Yes you are not crazy!. It is really leaking there.
