2018 4.6L Oil Filter Housing Leak?

I'm in the process of purchasing a one owner 2018 SR5 2WD 4.6L with 82,000 mi. which CarFax says was serviced regularly. I noticed a drop of oil on the filter housing and questioned the seller since they told me they made an oil change. After a couple of days, they said that this type of oil leak is common for these engines and will put on a Toyota recommended fix. I Googled and couldn't find any oil housing issue. I would appreciate any guidance!

 

I have never heard of that. Is it the black plastic housing? Many of us switch to the aluminum.

 

As I am new to the gen 2.5, all I can say is that the drop I observed was on the aluminum(?) plug in the bottom of the black (material?) housing.

 

Make sure it’s torqued correctly. It could be over torqued which will also cause it to leak. The o-rings come with the filter cartridge so maybe replace it for peace of mind.

 

Any leaks from the timing cover? Those are the most common.

 

I don't know how to respond individually, but Dalandshark : yes I don't know what they did.
Rocko9999 I didn't look specifically but the front of the engine looked clean.

 

Yep that is the filter drain. As mentioned, replace the o-ring on it and don't overtorque it. You will only get a few drops of oil when you remove that plug.

 

To respond individually (called a tag) , you just put the @ symbol in front of the username that you are directing your reply to. For example I'll tag you @Torgo

 

Thanks for the guidance. On my first oil change I'll inspect the housing and drain plug and replace/upgrade as necessary.

 

Make sure to install the large o-ring on the correct spot (seen it before) and use oil to lube both o-rings before installing as they can catch and tear causing it to leak and can make the next removal difficult if not done.

 

I also have a 2017 tundra 4.6l v8 that I purchased used and it was leaking on plug at bottom of black plastic housing... I replaced with the Toyota aluminum oil filter housing with part #
