2015 Mazda 6
Just did an oil change and while I had the plastic cover off the motor, I sprayed the engine bay off since it had a lot of sand/dirt, (which I do with all my carS) didn't spray any connections directly, just short burst in the areas which has the build up of dirt. once done, wipe it dry and put the cover back on. Never had any issues with this with any car in the past.
What I found odd was once everything was buttoned up, I did a final check on my oil level since the car was sitting while I cleaned it up, went to add a touch more oil and under the filler cap I noticed a bit of water around the lip and what seemed to be under it? which is really odd, inside the filler hole I could see a drip of water which most likely came off the filler cap as I removed it and water dripped from the bottom side. I simply touched the cam with a towel and removed it. I highly doubt much of any water got in but it does seem like a tiny bit got in. oil level didn't change so that's a good sign lol.
Over all I'm not worried about it but it got me thinking, I know condensation builds up inside the motor and that gets burned off when the engine gets up to normal temps. I'm assuming minor amounts of water would do the same, as long as the oil doesn't turn brown or clearly show signs of water being in it, which in my case it doesn't.
Anyone have thoughts on it? Figured It couldn't hurt to ask here.
P.S the water under the cap could have very well been brand new 0w20 oil since it's friggin hard to tell the difference since its almost clear form being new and about the viscosity of water. The fact it was under the cap makes no sense to me making be believe it was oil. but clearly water from around the bottom edge of the cap did drip in the motor but very minor amounts.
Cliff notes, minor drops of water in oil from the filler cap, easily boiled/evaporated off?
