    It’s not the head. It’s the timing cover gasket. The timing cover has coolant running through it. Replace the gasket and you should be solid. I own a 88 Z24 cavalier with a 2.8l V6. That’s the 3.4 sfi same set up on that. So timing cover.

    Had an 03 Oldsmobile with this same exact engine, 217,000 miles, but it had an intake manifold leak and a head gasket issue, used some green fiber stop leak in both coolant and oil, was able to put over another 50,000 before it just wouldn’t compress any longer and she was too far gone. One of the best vehicles I ever had.

    • @unclemarksdiyauto
      @unclemarksdiyauto  8 หลายเดือนก่อน +2

    First pulleys I ever seen on the side of the block no radiator or cooling fans? No weep hole to let that pressure out? And with nothing but water coming out that should be coolant yes use all the pressure to get it out. You don’t wanna wait till the problems happen like the dealerships like. I’m just a diy far from a mechanic but Dust,moisture on sensors and connectors is what I think causes most problems. But my diagnosis is this engine was installed sideways lol

    • @unclemarksdiyauto

    Dude what a smart idea . I was driving last night (99 Sentra GXE B14) & I smelled coolant & my engine was overheating fast. I parked it & opened the hood to hear a loud hissing. Also from under the intake manifold coolant leaking onto the exhaust causing it to burn & create steam. Shit looked like my car was smoking. I jus ran her home since I wasn’t too far & left her to park. I don’t know if I wanna tear the motor apart to fix the issue or just get a new motor altogether.

    • @unclemarksdiyauto
      @unclemarksdiyauto  10 หลายเดือนก่อน

      I tore this one apart, did head gaskets etc, but must have had a warped or cracked head so leak continued. (No shops near us to test either) This stuff worked for about 6 months. Here is the video on it: th-cam.com/video/yhFQiejnwDA/w-d-xo.html
