cylinder head trouble
I just bought a 1974 360 4x4 f100 and i have been geting it road worthly well when i when to give its first oil change the oil pan was full of water and some oil abouta quart of water came out and then maybe about 4 quarts of oil and the oil filter was full of water with a little rust in it but i have driven it around the block a few times and never saw any sighns of milky oil so could the problume be somthing other than the cylinder heads?
if not are there other engines that have compatable heads with a 360 if i cant find any I an in helena Mt and some time used parts and new are hard to find. andy ideas would be great because this is a relay fun truck to drive!!

Well, water could be coming from a number of things really, heads, intake or block. any one of them could be cracked or something may not be seated right or there could be a bad gasket somewhere. the 360 comes from the FE family and im not 100% sure but i think any heads from the same family will fit(352, 360, 390, 428). You might have to replace the springs and stuff but i think they all will work.

So, are we talking coolant or actual water from outside? because really, if its water from outside, i wouldnt see how that could get in at all unless you drive it through water and its somehow getting in around the oil pan area (gasket, drain plug, dipstick) or around the timing chain cover. I wouldnt think it could get in around the exhaust either.

I was told that is had been in the drive way a year but he has driven it around the block here and there it started right up and did not look like it hadent been in and auto cacoon but looks can always be deceiving the water that was in the oil pan did not have coolant mixed with it eather is it posable that the oil pump was bad and did not pump water through the engine causing milky oil?

I believe you're jumping to a cylinder head problem with no proof, just speculation. Drive the truck with the fresh oil, monitor it closely and see what happens. Perhaps some kids decided the truck 'needed servicing'. It has happened. No coolant with the oil pan water is a good sign. I am assuming it gets cold enough there that the cooling system would have had antifreeze in it. The oil pump does not pump water through the block. That is the job of the water pump. If the oil pump was bad you would be hearing bad noises and have little or no oil pressure.

Yeah, i agree with ray, just put fresh oil back in it, drive it and watch it. Its really strange that you would have that much water in there and it probably had assistance getting there so i think you should be alright.

Sorry about the sentence structure but I have bee crazy busy at work and just wanted to past back quick. You guys have been great. As for the oil pump thing I totally understand that the water pump sends water through the engine and the oil pump is for oil. But what I was unable to convey in my first post was I was wondering if the water got in to oil pan some how and the oil pump is busted so water in the oil pan never got pumped through the engine. But I think I will do some more looking and if every thing looks good I am going to take both of your ad vice and put oil back in it and just watch it. Thanks

Ok guys I pulled the oil pan tonight and looks like there is a long spindle (or it used to be hex head shape ) from the engine in to the oil pump and this rod has been twisted in two with some good torque. Which I am assuming makes the oil pump inoperable if the rod is busted? So this could be the reason the oil was never milky. But I am still left with the question of where this water came from? Tomorrow I will be pulling the valve covers to examine the heads and intake manifold. Just a side note is there anything I should replace besides the oil pump while I have the oil pan off? Thanks for all your help

If the drive to the oil pump was 'busted' you probably have bearing damage if the engine was run that way very much. An engine without oil pressure is short lived. Possibly the water in the pan froze and locked the pump. Yes, pull some bearing caps and see what you have. I would be more concern with the lower end condition than with the heads at this point.
The water intrusion is of course, still a big question. Was there antifreeze in the truck? Or is the block or heads cracked.
Wishing you the best in what you find.

As far as i know they are the same heads. The only differance between a 360 and a 390 (that im aware of) is the stroke. Maybe different valve springs?
