Roadman 09-25-2012 05:17:38 199.38.59.2 Report to Moderator	I've had this tractor for 3 years and haven't had a bit of trouble. I change the oil before I start the season and it has never used a drop. Yesterday while grading the driveway, the engine started rattling and white smoke came from the exhaust. I shut it down, checked the radiator and no steam. Checked the oil and it was at the full mark. Where do I start to figure out the problem or do I just plan on a rebuild. Thanks Clay [Reply]   [No Email]

The numbers are as follows: cyl Dry Wet #1 90 120 #2 70 40 #3 90 100 #4 93 100 When I spin the engine with plugs removed, water squits out of cly. no 2 Cyl. No. 2 plug is wet with water. All other plugs are as blackish brown. What do ya"ll think is the problem. Thanks: Clay [Reply]  [No Email]

Thats good news and a fairly simple fix. Which head gasket do ya'll recommend. Also, I read in one of the archives that Fel-co makes a rubberized cork gasket for the valve cover. I don't want to uses a sealant with the gasket but I don't want it to leak. Any help with the gaskets will be appreciated. Thanks: Clay [Reply]  [No Email]

I was looking on this site at the gasket sets and they have different ones for 1/2" and 7/16" head bolts. Do you happen to know which bolts the 1957 850 has? I'm 30 miles from the tractor. Of even better do you happen to have the part no. for the Felpro gasket set? Thanks again for your help. Clay [Reply]  [No Email]

I checked the bolts last night and they are 7/16". The Part No. for the gasket set is a great piece of information. I will put that in my files. Now that we have diagnosed the problem, I will probably start a new Post on replacing head gasket. Even though I haven't had to ask a lot of questions in the past simply because I haven't had any problems with my 850, I read this forum every day. Ya'll are the greatest.

It will add a little more info as to the condition of your engine, i.e. rings and valves [Reply]  [No Email]

I don't know what spark knock sounds like. It seem like if it was a broke ring or piston, it wouldn't start and run like it does. I'm going to start with the simple stuff and proceed from there. Changing the gas and doing a compression test are the simple things. Any other advice on things to check will be appreciated. Clay [Reply]  [No Email]

Take a look at the spark plugs. By "rattling" do you mean spark knock? If so, I suspect a head gasket problem. Dean [Reply]  [No Email]

Got it piped with a fuel filter. Hope thats the problem. If I had to pull the engine it won't be near as bad as removing the loader. I think you can pull the head without pulling the engine. The tractor was running great and this happened all of a sudden. It will still crank and run but will rattle and blow white smoke. Clay [Reply]  [No Email]

Next look at all the plugs. They should look a little brown on the ends but if any are real clean then you have or may have a coolant leak. You can also pull all the plugs and with them out spin it over and watch for water to spray out of the plug holes. As for the knock that could also be caused by water in one of the cylinders. Many years ago my 841 did about the same thing and I have blown a head gasket and I to have a loader on and did the repair with the loader still on. [Reply]  [No Email]

I sure hope its a head gasket. I sure don't want to have to pull the loader to get to the engine. The engine has been strong and did not burn any oil. Can't beleive it just went bad all of a sudden.

Drove it to the shop and parked it and let it cool off. Pulled the hood, gas tank, then the head and had it back up and running in 24 hours. [Reply]  [No Email]

Early in the days of my Ford rebuilding, I bought a non-running 4000 (800 later series) and noticed a crack in the head. I went to a Ford restoration shop/dealer and had a conversation with a machinist while I was buying a rebuilt head. The guy said that that engine had cracked head problems and it was good business for him. He would drill holes in the crack and drive in lead sticks, about the size of regular spaghetti adjacent to one another and fix it. I bought one of his heads and had no further problems. So, white is water/condensation/running cool and I'd just assume you had a cracked head. If you pull the radiator cap and rev it up you would normally see bubbles in the tank if it were.

I would drain the tank and carb bowl and put some good new gas in it to see if that helps first. [Reply]  [No Email]
