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.

All GM cars from 1994 to on up the 3100/3400 engine is famous for bad intake gaskets. When the gasket goes you loose coolant by either externally outside the engine or internally inside the engine. Check the oil for overfull condition and it will look like bright orange or milkshake color. Also if you drove on it overheating or if its full and overheats right away you also blew a head gasket. A compression test will confirm this. If you replace with good gaskets with the metal and rubber type do not use the plastic cheaper version. Then the intake gasket leak will never happen again.
Keep in mind what I am going to say is via long distance. I would need to check it myself to make any solid judgements. The leak-down test would show a leaking head gasket IF the gasket is leaking all the time. But it is possible the gasket is only leaking when the engine is hot. A leaking head gasket is the most common way you get extra pressure (bubbles) in the cooling system. The head gasket can leak when the engine is hot and you would not always see oil in the coolant or coolant in the oil as you would if it leaked with the engine cold. Another problem could be the radiator cap. It may not be able to hold 15 or 17 psi of pressure when the engine is hot. If the coolant is not under pressure it can boil (bubbles) before it reaches 250 degrees. Another factor is the radiator and fan. If the fan is not running when the engine reaches 220 degrees, or the radiator is not able to dissipate the heat from the coolant, the engine can run ok until it gets to 220 degrees then keep getting hotter. If the water pump were failing, it should start overheating right after you start driving the car.
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.

that flat 2.5 four cylinder engine is prone to leaking head gaskets. i would rule that out as possibility as its symptoms are exactly as you describe. if you do it, there is a special subaru coolant additive sold at dealers to put in systems that are not leaking. it will prevent, not repair a leak.
White smoke is a sign of water/condensation (due to the coolant additive)......worst case scenario, you have a head gasket leak (minor at this stage), or you simply need a tune up......as white smoke on cold start up could be normal...has it just started happening, or have you only just started noticing it ???
When was the last time it has been serviced (plugs, oil etc)
Hello, The blue fluid will turn yellow, once you use the fluid throw it away. Do not mix it with the good fluid left over. I have never kept it long enough to see what happens later. It also sounds like you have a plugged radiator. Someone may have put stop leak to try and cover up a leaking head gasket.
When the coolant hose broke,did the engine overheat?If so,it seems through your description that the head gasket has blown.The most common cause of water/coolant in the cylinder is a blown head gasket.It will need to be replaced.Take the vehicle to your mechanic and explain to them what happened .This helps them to fix the problem, knowing what may need to be done and what to look for.Hope this helps.
