Hi,
Long time lurker, first time poster. I recently purchased a '99 4Runner. I believe I did pretty good diligence on the inspection prior to purchasing (no milky stuff under the oil cap) but now after changing the oil I'm concerned I might have a blown head gasket. I was considering trying out Bars Leak. The guy I purchased it from did all of his own maintenance, had old school painter's tape with the mileage on the windshield... I noticed a Fram Extra Guard filter - so leads me to believe he did stuff by the cheapest cost. Is this what dino oil looks like on a 160K engine or does it look like there's coolant in the oil? I just filled with Mobil 5W-30 EP High Mileage, a full quart of Marvel Mystery Oil, and a Fram Ultra filter. I hope this guy didn't screw me as he did not mention any problems mechanically or with the oil. To add to the mystery, car also had a CEL a few days after I drove it for an EVAP leak (despite me checking with my own scanner, none current or pending) - but where I bought it from doesn't test for emissions so I let that go. No bubbles under the radiator, no noticeable leaks anywhere, and no white smoke out of the tailpipe. I did a block test (chemical test with liquid that changes colors if exhaust is detected in coolant) and it came back negative. The pictures have me flashing my light on the oil, was doing it later at night so not natural lighting, not sure if that distorts them. I just fear it looks like the dreaded chocolate milkshake.
