I have a ford 850 I bought this year at an auction and I am fixing it up before I start using it. I was replacing the temp gauge the other day and noticed on the black where the sensor screws into the block some tiny bubbles when running that got a little more frequent when accelerated. I assume this is a bad head gasket. The water only stayed right there and didn't run down the head. There isn't any water in the oil and no oil in the water. It was running a little warmer than I thought it should but did not run hot. I was told to try just replacing the gasket first and not worry with having the head resurfaced. Can anyone shed any light on this. Thanks

I'm guessing that the head to block interface is where you saw the bubbles of fluid? If so, it does sound like you will need a head gasket.

By all means, if you go to the trouble of pulling the head, have it decked! Sometimes you have to spend a nickle to save a dollar. Take the head apart and see how much guide wear, valve wear and spring tension you have. Might as well have the valves ground too. Do it once, do it right. It does cost more up front, but a lot less down the road.

Man, is it fun to spend someone else's money!

Thats right. The fluid is showing on the right rear where the head and block meet. Thanks for your feedback.

Just a warning from some one that has been there done that. If you have the head done, as in decked and the valves you better also do the lower part of the engine or it will go because you have done the top. Engines wear all at the same time so it you do the head you also better do the bottom. Doing the head will up the compreassion and that will cause the rings to blow out the bottom fast. Ya you might get a year or 2 one it if your lucky

I have heard that a lot, too. It is true in cases where the lower end is already near shot. But I have also rebuilt many heads and not touched the lower end ---> and had the engine go thousands of more hours or 100k+ miles. It all depends!

If you pull the head and there is minimal cylinder bore wear (feel for a pronounced ridge at the top), then the lower end is usually fine. If you have a pronounced ridge (2-4+ thousandths) or see vertical scoring (stuck / broke rings) then, it needs some lov'n.

When you pop the head, snap a few pictures of the inside of cylinders.

I'e rebuilt engines off and on for the past 30 plus years and I have neverhad one last that all we did was a head, and I'll never just do a head again. I believe in doing it right or not at all. Now if this guy where to pull the head and it looks ok I'd say just replace the head gasket. I've seen a many Ford tractor engine blow a head gasket and that was all that was wrong with it. I'e got an 841 that blew a head gasket once, I was over working it when it did. I pulled the head and replaced the gasket and its been just fine since and that was more then 10 years ago

On the flip side to that.. I've seen cases where peopl ejust dropep dthe pan, did mains, rods, and rings.. and slapped back together.. thus not touching hte top end.

I'm quite sure there are many engines that are running on an upper or lower... I guess if you have an engine that has had a lower already.. the upper is all that left... 'course.. ya gotta drop the pan to check the lower with plastigauge.. and if you are that far.. might as well drop in new shells.. etc.

I appreciate the input. My dad was a firm believer also in not doing the head without the bottom end too on the old Chevies when he was a mechanic years ago. The guy who I deal with for parts at a used Ford tractor dealership told me what he does is just replace the head gasket to start with unless it is obviously bad. He said that usually takes care of it but I feel its never a bad idea to get second opion. Thanks for ya'lls help.

Ya I learned the hard way to never do just the bottom or just the top or it will come back and bite you on the butt most of the time
