Still smoking after head change
I have a 4.0 OHV with 105000 miles that started pouring white smoke/steam out the tailpipe on startup in the morning and after sitting for a while duting the day. It would clear up after a few minutes of driving. Sometimes in the morning it would bog down and run rough until it cleared itself out.
I pulled the plugs and cranked it and coolant shot out the #4 cylinder, so i decided to replace the head gaskets.
Once I got it apart I found cracks between the valves on the heads at the #4 and #3 cylinder positions. They both looked like they were steam cleaned in those two areas.
So I ordered new heads and replaced them and the gaskets, put everything together, prayed, and started it up. It blew a crapload of white smoke for about 5 min(which i kind of expected for the first start) and then settled down.
The problem is that it is still blowing white smoke at start up, it is less than there was before but it still there and more than there should be for the temp outside. goes away after driving for a while.
I took the plugs out and cranked it after letting it sit overnight and no spray of coolant like before, so that is good.
Anyone have any ideas? Should I take everything off again and re-torque? How do you even check to re-torque with those bolts that you turn an extra 90 degrees? Can't just turn them another 90 can you?
I just want it to stop before my engine stops,
