im losing coolant, i cant find a leak anywhere and my oil gauge sometimes twitches
 

so falling down the P0132 bottom-less pit i end up getting asked by many if my headsets cracked. truth of the matter is that i do not know hot to diagnose that myself (other then compression test but im waiting on my compression tester)

below i have attached some images and a video. doesn't seem like there's any coolant in the oil tank but i honestly wouldn't be able to notice that much unless it was pretty freaking obvious which in this case its not.

Compression check, test coolant for exhaust gasses, and do a pressure test on the cooling system. You can get test strips at the parts store, and pick up the rental tools at the same time.

For rental you'll need:
1) https://www.autozone.com/loan-a-tool...tor/391378_0_0 (This will tell you if your head gasket is shot or not, make sure to get the fluid for it as well)
2) https://www.autozone.com/loan-a-tool...set/424906_0_0 (to test compression)
3) https://www.autozone.com/loan-a-tool...ece/449951_0_0 (to test if the coolant is leaking out somwhere in the system, be careful not to over pressurize the system when testing the system)
