Hi, my (10/71) FJ40 has a strong exhaust smell and white smoke coming from the exhaust. I changed the oil a couple of weeks and the oil had a strong gas smell to it. There was not a milkshake look to the oil. I performed 3 combustion leak tests and the liquid did not turn colors (it stayed blue). I just replaced the fuel pump and fuel filter. I adjusted the air/fuel screw a bit. I did a compression test and all 6 cylinders were good (140-150). It runs strong and steady at idle. The exhaust spews some nasty brown liquid (photos below) and when I give it more gas while idling it does more liquid, a little alarming how much comes out. I have not driven it a lot so it does sit but always starts. I took out all of the spark plugs and they looked dark at the top.
I’ve read all of the similar posts to get the ideas to do the various things above but don’t know what to do. Am I kidding myself and this is still a blown head gasket? Any other diagnostics I can try? I would appreciate any other advice anyone can offer. As far as I know this is the original 1.5F engine. I’ve owned it for almost 2 years so I’m not sure of history. Thanks
