Is this easy to fix? Is there an additive that can help plug the leak...it seems to be the gasket. It only happens when it is cold. I drove to Florida and there was no leak down there but in Ohio before I left and after I came back the cover leaked.

Re: Toyota Camey oil leaks around timing chain cover
Addatives don't fix the problem. They only make the problem a bigger deal when they stop masking the problem. You have a main seal leak. if you don't know what that is go get it fixed. It is not a simple fix.

Did you check around the upper timing chain cover gaskets? I found that these should be replaced along with the valve cover gaskets, otherwise there will still be leaks. They are easy to replace if you have been able to replace the valve cover gaskets.
Dear Sir, Here is the oil leaking Problem Identifying Technique
Engine oil leaks from the valve cover gasket are common.
The intake manifold plenum gasket may leak and cause increased oil consumption/burning and a spark knock during acceleration; the gasket should be replaced.
External oil leaks from valve cover gaskets, intake gaskets (front or rear), and the rear crankshaft (rear main) seal area are common. The rear main seal is an unlikely source. Normally, the bearing cap mating surfaces (as well as the sealing surface between the oil pan and bearing cap) are the source for the leaks.
If the oil filter casing shows signs of distortion from excessive oil pressure, theoil pump should be replaced.
Often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.
Carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.
Your spark plug tubes are leaking. The spark plug tubes are set in the valve cover, where the plugs set. It's an easy fix, I recommend a set of spark plug tubes that come with a valve cover gasket. Pull the valve cover and swap the gasket and spark plug tubes, problem solved. Take you maybe 30 minutes to finish the job. I recommend at least replacing the plug that was getting oil all over it. At least wipe it down real well and let it dry good. Common problem, easy fix.
If you have any comments please feel free to leave them here.
The timing cover itself does not seal any oil from leaking. It is just a cover to prevent debris from getting into the timing belt and ruining it.
To find the oil leak you will need to remove the timing cover and inspect the seals behind the cam gear, crank gear, and oil pump drive gear, and the oil pump to block seal. The most common leaks on these are the cam gear.
CHECK FOR LEAKING WATER PUMP WEEP HOLE OR GASKET.ALSO CHECK WATER PUMP HOSE FOR LEAKS.IF ALL LOOKS GOOD.YOU COULD HAVE PINHOLE LEAKS IN RADIATOR CORE LEAKING ON FRONT OF ENGINE OR INTAKE MANIFOLD GASKET LEAKING COOLANT.
Hi Toyota Ed
The silver plate seems to be a blank as there are no oil pipes running into.
The leak seems to be weeping along a secondary sump if that makes sense.
If looking from the bottom you have a black sump that bolts onto a silver alloy cast that then seems to be bolted to the lower engine block this seems to have a flexi seal of sealant ( can feel it where it has seeped out) this is were i think the leak is comming from.
Especially when you stop the motor you can see it seeping out around here, but as you know oil sometimes can travel in weird ways and i will check again around the blank plate that you mentioned.
Would i be able to repair it if it is the main sump/ gasket and do you have to remove the motor?
