    Do you also have water in the engine oil (oil will have brownish color) ?

    Either way, oil in water, water in oil, the first suspect is a leaking head gasket.

    You are probably losing coolant which is causing the overheating.

    More info, let me know.

Oil in the antifreeze means the head gasket is in need of replacement due to leaking between oil and antifreeze passages at the head.

The engine may need to be flushed out as well (antifreeze).

Check the fan to see if it operates properly.

My 2003 Ford focus blew a head gasket a while back. I got fixed that, changed out the water pump, thermostate, water resevoir, and a few hoses. It started to overheat again, but the thermostate wasn&#


If you got a blown head gasket, water is getting mixed with your oil, pretty much ruining it, and your oil's viscosity will be affected, causing oil pressure to drop and your light turns on.

How do you know your car is overheating if it's not showing in your gauge?

When replacing blown gaskets there are a few things that is best to do, like sandblasting the heads, clean, scrape block and use proper torque an sequence, only removing old gasket and placing new ones won't fix the issue, those gaskets go through extreme conditions, expansion, temp changes, etc, they need to be put mindfully. I mention this because it seems you changed a lot and ended up with the original issue...

If your gasket is blown you need to fix that asap, then identify where is your coolant leak/blockage that causes alleged overheating, doing a coolant flush might help. Good luck.

Porsche boxster 1998 overheats very easily


it could be the thermostat has gone bad-does top hose get hot if no then likely bad thermostat, water pump is bad if pulley is wobbly it is bad, radiator is clogged with corrosion, look in rad when cold and if it is dirty or milky it needs flush and refill with new antifreeze
