  • White smoke
  • I bought a ford 4000 with a blown head gasket. It barely ran to get it in the shop. Replaced the head gasket and it runs smoother than ever. The only problem is that it blows white smoke for about the first five minutes it cold, then clears up. Any thoughts?

  • Re: White smoke- Update
  • I retorqued the head bolts tonight and fired it up again. It smoked less than before I retorqued, but still quite a bit. Like before the smoke cleared up after about 10 minute of running.

    After I initially did the head gasket I fired it up and ran it for about five minutes. All seemed good (NO smoke) so the next day I topped off the radiator, checked the oil and fired it up. This time I had LOTS of white smoke. Ran it for about 15 minutes and it cleared up. Once it cools off and I restart it smokes. Once up to temps it stops.I put the gasket in dry before. Should I get a new gasket and try copper coat this time?

  • Nice that you resurected another deciple.
    White smoke means that we have a new pope.
    Also can mean yo are burning a little antifreeze.
    Retorque head to specs and watch your oil and coolant.
    It could be burning old residue but yo probably cleaned that out.
    I got smoke from one of mine when I used gas with stabil in it.
    How long have you run it already?

  • You Gona have to monitor the water and oil levels. May not be a head gasket problem. Sounds like you follow the procedure for torque.

  • There may be damage left behind from the previous gasket problem. Or, something might be cracked. Here's hoping a re-torque will stop the smoking though.

  • How many ft. lbs. should I retorque to? Thanks!

  • Re: White smoke
  • That makes me wonder if you torqued at all.I dont have a manual beyond 600 series.

  • Re: White smoke
  • You didn't say if it's a diesel. DId you check compression before R&R'ing the head gasket? If it's a diesel the smoking could be caused by a lazy injector that doesn't provide a proper spray pattern until warmed. Same for a higher time engine that is worn and doesn't smooth out until the combustion chambers warm enough for complete combustion. Cold weather, cold fuel and a little wear equals white smoke on initial start.

    If you don't know the head torque (gas or diesel) and tightening sequence get them. THe information is on line or simply call a Ford tractor dealer. It's been my experience they are willing to share the information.

  • Re: White smoke
  • I torqued to 70 lbs per the manual and went in the specified order. I asked the question because I see in the archives other people recommended higher torque ratings.

  • The manual is fine, No need to reinvent something.

    Just do it in 3 steps: 25-25-20
