Oh... that's what I worry too! Hopefully the worse is Gasket issue!
Oil Level just normal, no less at all, so far!
^this
to me, even a headgasket is bad.... this is something i personally dont wana have to deal with....
1)check if thats actually oil in your radiator... pics not clear but seems like it.... (alittlebit is fine, alot then not fine)
2)check if there is any water in the engine oil.... check dipstick, oil should be clear, no check the oil cap, if its really bad, you will see lots of water/condensation on the oil cap (or shove your finger into the hole and feel around it, take your finger out and check for signs of water, if theres water, confirm headgasket kaput.
**only check when car is cool, if you get burns dont blame us ya
3)sometimes if the coolant goes low for no reason, its actually leaking into the combustion chamber and gettting burnt. To check, look at the exhaust for white smoke which points to coolant or just water vapour (dont test in the rain, panic last week cause car was spewing loads of white smoke, turned out to be a puddle of water in my exhaust which pooled in the pipe due to my parking on a slope and rain....
)
**ppl do say burning coolant smells sweet, i duno, never smelt it b4
4)for the fun of it, you can take the radiator cap off, then start the car, let it run til the thermostat is open (you should see water swirling) sometimes bubbles pop out the neck.... if there are bubbles, well thats exhaust and its quite bad
good luck
**wana add that a headgasket is probably one of the worst things that can be happening to you anyway (short of a cracked block ofc), not sure whats the liquid's designated flow in your car, but
in my model, the automatic variants dlow atf into the radiator as well, in some cases, the radiator vracks or springs a leak internally mixing the 2 liquids... you should also check if the oil (if it is oil) is atf fluid.... if yes, best you check your atf fluid via the dipstick.
Op, the whitish and yellowish stuff at radiator fill hole neck looks like oil crud, indicating engine oil mixing with water.
Check with bare index fingers whether it's oily to touch/feel ?
Bros. appreciate your advices and suggestions! So far what I did is Touched and Feel the Brownish thingy & the water inside Radiator, don't feel like Oil !!
