Default Signs of a bad headgasket 99' 2.5RS

The motor was replaced with the timing belt, ect last summer. Has around 100k on motor. Did the timing belt, pulleys, ect.

I noticed the motor is starting to loose coolant, however my radiator was also replaced a few months ago along with a new coil pack. I added some coolant and noticed the motor heated up quickly but didn't over heat after 3 hours on the highway (yes lots of highway driving). My oil was low so I added some and now after driving it a few weeks the oil is wayyy up on the dipstick. I also noticed a small little puddle after parking it over snow.

The weird thing is that my motor isn't running rough and no check engine lights. Seems to me they are mixing, but the oil isn't milky at all, just full. And the coolant level goes down. Odd.

Are you checking oil while it's warm or cold?

Was it a puddle of coolant or oil?

Did you do the radiator? Or a shop?

When you get a moment, crawl up under your car and look for any signs of leakage. Be very meticulous, have a light handy. Look around where the block meets the heads for leaks "location of head gasket". Keep in mind you can also loose coolant from the radiator in other ways.

1.) A bad radiator cap will not hold pressure correctly and cause coolant to drain out into the reservoir then over flow out on to the ground.

2.) You can have a mild leak in the coolant lines "check your hose clamps" or a bad water pump, check the weep hole around the pump.

The oil going up and down on the stick thing isnt important, you want look in good light for discoloration "milky" on that oil dip stick thats the 100% sign the Head gasket isnt sealing properly. Feel free to post a pic on this site of the color of your oil "on the stick" and we can go from their.

Loosing coolant can happen in many ways doesn't always mean head gasket.
Also try warming up the engine, then running the engine with the oil cap off and looks for steam.

You can pull your spark plugs and see if any are white. If they are, you're burning coolant.

The radiator was done at a shop and Ill have to pull my plugs at some point when I can get home. Never pulled plugs before.

Like I said ive ran it for a few months and it would be low on oil, filled it once. I also filled up the radiator with a some coolant here and there.

Ill try to post a picture of my dipstick, like I said its the normal oil color, nothings looking milky. I just noticed I pulled it and noticed the oil seemed really high.

I did replace the thermostat because it was heating up and going to normal, I did that maybe December, the small leak I noticed one time was a cold start with heating up, maybe a few inches wide nothing like a puddle. I also notice my heat isn't perfect and could be from the coolant being low or airbound. Coolant color looks normal, nothing dark or black about it, maybe a little thicker but I used a generic brand.

Coolant might not have been "burped" after they changed it.

If you can't determine a definitive leak, have a compression test done.

Ill have to get that done at some point put it on a lift. I just don't think its worth replacing at this point might just get rid of it as is. I also smell coolant too after driving everything just seems strange to me.

Could be a leaking heater core, your heater core is part of your climate control inside the car, it is responsible for heating your car in the winter or when ever you need heat. Over time the heater core inside the dash in the HVAC box, will corrode and leak "antifreeze" this will cause a coolant smell after driving sometimes and coolant will be on the ground under the car as well. If its leaking inside the your cars HVAC box this means it could need to be replaced which means taking the dash apart to get to the HVAC box.

Its can be hard to replace depending on how buried it is. An easy check is to crawl under the car and look for the drain tube from your cars HVAC box

See this thread post #1 for what it looks like:
http://forums.nasioc.com/forums/show....php?t=1718109

Its just a simple tube that points down you can put your finger inside it and see if any green coolant is present in that tube. If there is then you need a new heater core.

Do you have a little nub with a small hose next to the radiator cap?

No, not the hose to the overflow reservoir, the other side.

Mine leaks from there -every few months, I have to put a new hose cap because it can't handle the pressure, tears, and starts leaking - slowly, then more as the tear gets worse.

Push on that after the car has been on for a bit to see if coolant leaks from there.
