78 f150 motor problem
Hey guys I'm hoping you can help me I have a 78 f150 4.9l 300 straight 6 and the oil had water in it and it was a yellowish mustard type of look. So I put a new head gasket kit in it and changed the oil and filter yesterday and i drove it today and I check the oil and the dip stick is covered in the same yellowish mustard oil. Idk if its just still some left in the block or if anyone knows of anything else it could be. Any info will help thank you

That's what I was afraid of. I was hoping it might be something with the water pump seal or something but I don't no much about motors so I'm lost other than thinking it might be a cracked block. Thanks for the info.

Water in Oil.
Have you checked the tail pipe for fluids? How many miles on the motor? It takes alot to crack a block. Maybe a cracked head. Did you have them cleaned and checked out before reinstalling? Also your head(s) could be warped.
Much Luck!

no I changed it out myself I cleaned out the heads is good I could and wiped everything down as good as I could but I'm not a mechanic so as far as it goes is doing things by the book I don't know how to do it that way

Ok. I would recommend having your heads checked out from a machine shop. Cost me about $160 for both heads be boiled and checked for cracks And worse case, you buy a used head if that is your problem.

There should be a block plate on the valve cover for that purpose.To stop the oil from shooting through the breather cap hole. You should be able to see it by taking the cap off. Or you can feel it with a screwdriver. It is held on by 4 screws and you access it with the valve cover off. Should be one under each cover for the breather valve and pcv.Hope this helps.

You may have already fixed the problem and the oil is in the block, Take the t-stat out, by the plastic flush tee that goes in the heater hose, start it up and let it idle with the garden hose running in it enough for it to slowly flow out the open rad cap. And let it run until the water is spotless. Buy some beer cause it may take awhile.
Keep in mind the oil is lighter than the water, so what may look like alot of oil may not be much at all.
