    THANK YOU! This has been the basis for replacing the head gasket on my son's 2004 saturn ion 2.2 . Your video made the job SOOOO much easier. Thank you.

    Was this an LSJ??? I just realized after watching for the 1000th time. I’m about to do my timing and putting it all back together and it’s impossible to find a video that’s not a 2.2. Thank you so much

    Hey, I’m starting this tomorrow and I had a question about the timing chain. I’m not sure if the car will even crank yet, what would you do in this case? I noticed you drained the oil first, if the car does crank shouldn’t I wait to drain the oil until after the timing chain is positioned correctly? I don’t know anything about this, it just seems like it would be bad to turn the engine on without oil or coolant, mainly oil. Love the video, thank you!

      Good question. The oil needs to be drained otherwise it will spill out of the side when you pull the timing cover off. There is enough oil between the bearings to allow you to turn the engine manually. But never start the car or use the key to turn the car over without oil in it 👍

      So by turning the engine manually, would I just do that by forcing the chain/sprockets to the right until the indicated exhaust and intake labels are at 45° ?

      @@user-uf7zv8le1w Before you take the old chain off put the crankshaft bolt back in and turn the engine with a ratchet on the crank bolt. It's easiest to turn the engine with the spark plugs out but it's doable with them in 👍

    Just got mine together, the initial problem was coolant/oil leaking out of where the seam was. Like you said in the video. I put the 2 layer gasket on and its leaking still. Can i get the link to the headgasket you used?

      Found a crack in the head. Replaced it with that felpro head gasket and no more leaks.

    Do you know how to test this head before you in stall it??????

    • @ValleyMobileAutomotive
      @ValleyMobileAutomotive  Рік тому +2

      The only diy method I know is the water method, where you fill the intake or exhaust with water with the valves closed to make sure the valves are sealing. Usually when I do a head gasket the head goes to the machine shop and they work their magic.

      @@ValleyMobileAutomotive ya get the head off and you get just a little mower fuel pour just little were the valves are with the head level facing up if the fuel stays it's a good head but any small cracks the fuel will run out on the ground it means it's junk it works I hope it helps. Thanks

    Hello, I just replaced the head gasket on this same engine and I had to take the head back off due to leaking valves. Have you ever reused these head bolts? I used new head bolts and I havent driving the car more 6 miles I would say. Would you use them?

    • @ValleyMobileAutomotive
      @ValleyMobileAutomotive  6 місяців тому +1

      Because these are torque to yield bolts once they are tightened they should not be reused. The bolts stretch some during the tightening sequence, the second time you use them they may not torque correctly and you could end up with an improperly tightened head.

    Do you absolutely have to remove the intake? And if you do, is the intake gasket reusable? Thanks

    • @ValleyMobileAutomotive
      @ValleyMobileAutomotive  11 місяців тому +1

      You might be able to get away with leaving it on. But it will be cramped and awkward pulling the head off with it still on. The gaskets can be reusable but when you get a head gasket set it comes with a new intake gasket. If you are going as far as replacing the head gasket just go the extra mile and pull the intake and replace the gasket 👍

      He pulled the engine to show how to install the timing sets. One for the balance shafts and the other for the timing chain setup. If he didn't pull the engine. It's very hard to show all of the marks .

    What if the cam sprockets are not set at 10 and 2 if your changing the head?

    • @2nickles647
      @2nickles647 3 місяці тому

      Take a long screw driver.
      1. Insert in #1 piston.
      2. Turn the engine in the counterclock wise direction about 80 degrees. You will see #1 piston drop about 2 to 3 inches
      Note: In that position, all of the pistons are about mid travel
      Do not try to go any further
      3. Align the cams to their assign marks.
      As you turn the engine, the cams will snap to the neutral positions.
      Use a long wrench to slowly turn each cam.
      4. Set the cam sprockets
      5. Reinstalled the long screw driver and turn the engine in the clockwise direction very slow. If you feel a bind. STOP.
      6. Now and line up the crank timing mark.
      Note: Both cams are in the neutral positions. So all the valves are closed on the head.
      7. Install the main timing chain as per the instructions.
