I just bought a new camry and changed the oil around 800 miles, along with the filter. It uses the cartridge type filter. I am using OEM filter and gaskets.
The filter housing is leaking, even after replaced the filter housing gasket with two new OEM gaskets. I am certain it's the housing, not the drain plug.
The gasket is in the right spot, and I am not picking it off so to gouge the metal housing. It drips very little, I can barely see a drop accumulate - maybe a drop every few minutes. Will it just stop in time? I am at a loss here. Does anyone have experience with this?
Are you sure its not the residual oil left below the o-ring leaking down after you install the housing?
Because this sounds just like the first time I changed our Sienna's oil (same engine as your Camry). Changing the oil filter creates such a mess that, after you install the new filter and run the engine, all of the residual oil from the filter change (below the o-ring) drains out of the housing. I thought it was leaking and changed the filter/O-ring AGAIN. Same thing happened again so I went for a 15 minute drive, came back and there was no leak or residual oil anywhere. You just need to heat the engine up so the residual oil will drain out/burn off.
Just a complicated design thats frustrating before you realize whats going on.
Since then I now run Fram Ultras for 20,000 miles to avoid the filter change headache. Its still a pita because even though I know whats going on, I still have to drive around for 15 minutes to get rid of the residual oil to be sure there isn't really a leak with the filter housing.
Well, after a new OEM oil filter housing came in to my dealer, I removed the original (~880 miles on the factory housing) and discovered a small U shaped scratch on the large O-ring seating surface for the filter side. Also discovered a burr on the engine side, but it doesn't seem to affect o-ring sealing. Not sure if I put the scratch there, but I will assume supplier/Toyota isn't metal tools for o-ring install/rework...
After cleaning both the new oil filter housing and the block side repeatedly with a clean rag, I used conventional oil for lubrication of the seals this go around. I had zero o-ring 'chatter' on install, unlike my last two attempts.
After about 10 miles of accelerator heavy errand running, no leak. Root cause: Scratched oil housing. Thank God it wasn't the engine side; it looks like it requires engine removal to do that one right.
I am looking to buy a plastic pick or maybe keeping a spare filter housing around after this. I was EXTREMELY careful and found this was still an easy job to mess up. The filter housing was $33 after tax.
Not a fan of this design. More environmentally friendly, but after burning through 3 filters/seals/drain tubes, not sure how much sense it makes
