- 2014 CX-5 Touring
Well this is not what I wanted to see. 137K miles on our CX5 Touring that we've owned since 2016 with about 54k miles. Last oil analysis report last July showed a trace of coolant present in the oil, and this oil change end of last month showed more coolant. I have noticed a *very small* loss of coolant over recent months, not a huge amount. The coolant itself still looks clean, and the oil looks clean. I did see a small amount of oily residue on the joint between the water pipe and water pump, up above the oil filter, but haven't seen any signs of anything dripping onto the ground or onto the lower engine cover.
I've read the other posts on here about 2014's with blown head gaskets. On those cars the engine apparently overheated at some point. I haven't had any overheating issues, or any engine codes of any kind. Is there any other way for coolant to mix with oil besides a blown head gasket, or worse, a cracked head? Surely the head wouldn't be cracked if the engine hasn't overheated.
I still need to check compression and test the coolant for any combustion gasses, but if there's no breach between the coolant and cylinders, I don't think those tests will show anything. We can't really afford another vehicle, but I'm highly experienced in doing major engine work (head-off work, head gaskets, engine out work, etc), so I'll just have to try to fix it, assuming it's a head gasket or maybe oil cooler issue.
We're scheduled to head out on our family vacation beach trip in just 2 weeks. There's no way I can work on the car before then. Hopefully we won't have any issues. Sure wish the car had a darn coolant temp gauge....
