I have a 62 f-100 with a 223 inline. yesterday I had one of the speedy oil changes done. They told me I had some water in the oil and it drained off first. I am thinking that I will keep a closer eye on it for a week and then "I" will drain the oil again into a very clean pan and do an inspection of the oil. I know my way around my engine but this one has me wondering on what is going on.
Any suggestions on what is causing it?
I will answer some questions first:
Not missing any water and no oil in the water.
runs ok, does not over heat
some carbon in the exhaust pipe.
No indication of any problems.
I have been using w30
I use about a quart of oil every 1500 to 2000 miles.
I only have speedy do it cause I don't have to get rid of the oil and I don't have a garage.
If I had a head gasket leak would that not blow all the water out of the radiatior first before water would get into the crankcase.
No. If any of your plugs are perfectly clean, that cyl is "normally" where your problem is, as it steam cleans them. But head gasket could be leaking to the oil passage and not combustion chamber. Another possibility is if you only run short trips, condensation could be built up in the engine. Trips over about 25 miles normally burns this off. Hope that is your problem, but check it out further.
I have a 20 mile one way run to work and then back at speeds at 50mph.
That should keep the condensate down. I will check the plugs this afternoon. and let you know how it is.
If I do change out the head gasket, what else should I do while I have it off. I do not know how many miles is on the old girl. the odometer says 65K but at 50 years old I don't know. I have had her only 2 years.
I think you answered your own question with your # 1 answer, if your not down any coolant then there isn't a head gasket/cracked block issue, my opinion. Besides didn't speedy say it was "water" and not antifreeze ? Like you said driving 20 miles each way would burn off any condensation. Reading the plugs is a very good way to identify the problem area.
If the oil looks milky, truck could have a blown head gasket that is only seeping a small amount of water.
There is no coolant recovery reservoir on these trucks (unless someone installed an aftermarket from an autoparts store).
When water gets hot, it expands, flows out the radiator overflow tube, so you're going to be adding water every so often.
What lb. radiator cap does the truck have? The radiator cap was 13 lb. originally. Peeps install 4 lb. caps on old rolling piles of misery to reduce the water pressure.
