Hey all,

So was doing a full oil change today and apon taking off the oil cap i found the white creamy milk stuff i've read about when you have a blown head gasket. Then when i drained all the oil at the very end there was very small streaks of the white milky color in the oil which from what i have read is what happens when the coolent or whatever leaks into the block with the oil. So i got ahold of a friend that works alot on trucks and hes going to help replace the head gasket if indeed it is blown which im 99% sure it is, ( white creamy milky color on oil cap plus white smoke form tail pipe, not clouds and clouds but constant ) which are both signs of blown head gasket. My question for anyone that can answer is maybe you can tell me everything im going to need to get to replace this. I plan on ordering everything at once so we can do it all the same day with as little trips as possible. If someone wanted to go a step more and gives links that would be amazing but i can do that

Specs are 1995 F150 302 5.0L V8 RWD

Thanks for any help

 

That white milk stuff you talk about isn't pointing necessarily at a blown head gasket. My wife has same problem with the 2000 expedition only because she drives a few miles each day. Usually its just condensation that hasn't been heated up enough to dissipate.

Do the oil change as you have and drive it. Check for codes. Use a leak test kit before tearing into the unknown.

 

If thats the case, what would be causing the white smoke from the tailpipe constantly? its not alot of smoke like clouds or anything but its very light and steady. I will be getting a leak down test that goes on the radiator with the blue test fluid and pump i see everyone use from auto zone within a day or two and see how that turns out. If its not the HG i have no clue what would be causing the smoke

 

What color is the smoke you see?
Blue Is oil
White is coolant
Black is too rich a fuel mixture
Grey can be to lean fuel mixture and/or build up of carbon and other deposits.

Are you losing coolant?
Have you checked plugs for really clean ones? A really clean plug that has several thousand miles on it is usually due to coolant/water intrusion.

The teardown sounds easy until breaking rusted lower manifold bolts, exhaust bolts, and the best of all, timing cover bolts.

 

I dont think im losing coolant, if i am its very very little, but again i do not drive the truck a whole lot, very little use right now( had to fix brakes / wheel cylinder and air injection valve / tube ) when i do start it up though most the time is a cross from white and blue, its hard to tell but its very faint blue tint to it, sometimes i cant see any hint of blue at all. I have not checked the plugs, probably should though, I will go ahead and do that tomorrow when i get home from work. Ordered a block leak tester with the blue test fluid i hear people have good results with that if it infact is a blown gasket or something completely different. as for teardown i know, im really dreading that if i have to, this truck was not taken care of by the P.O and all the bolts and such are rusted especially the manifold bolts, its rusted so bad that the bolts are deteriorating which i know isnt good, just dont want to deal with it right now(will have to replace if hg is bad)

If you dont mind, could you list the causes on how its actually smoking, like how oil is getting in there, or how coolant is getting in there ect

(Still learning about all this stuff, prior to buying this truck i had no exp. at all, so learning as i go)

 

as i said in your other post, it very well could be there is nothing wrong with the engine and it is just condensation from the engine sitting.
my falcon, galaxy, and 79 trucks get the same thing because they do not get run very much.
if you were to use it every day, the heat from running the engine would boil off the condensation in the oil and you would not see it.

 

Yeah, i have no idea why the thread was posted twice, i only did it once. But what would explain the smoke steam whatever you want to call it coming out the tailpipe constantly? I did just replace the air injection check valve and crossover pipe that was broken for who knows how long, because that was broken theres what looks like carbon or soot or something along that lines all where the valve was broken on the firewall and the same subsance in the tailpipe( a very thin layer) so maybe the engine is just trying to burn off all that junk in the pipe and the stuff on the oil cap is condensation and it was just bad timing that it was on the oil cap when i did the change. I bought a combustion leak tester that will be here next week, ill give that a go and hopefully i test negitive for fumes and what you said is right, would be a huge relief, then i can focus on some of the other issues and get the truck running how it should. Love the older truck and would like to bring it back to how it originally was at some point, i will also be checking the plugs today when i get off work and hope those are good, anything i should be looking for specifically other then fouling

Thanks for all your help, makes a beginners job alot easier

 

Tjc and myself concur its just been sitting to much.

You have fixed the mistakes made by the P.O. and now have run into paranoia. Its ok.

When I redid my engine after cleaning the block, heads and exhaust, when it first started, the neighborhood was full of smoke. All the oil that made its way into the exhaust and catalytic converters took forever it seems, to burn off. Once it did, I was relieved cuz I thought I had completely screwed something up.

Throw some seafoam or Techron in the fuel tank, and do some hearty, well deserved driving after all the hard work you have put into it, and breath a huge sigh of relief!!!

Then after a few days, check the oil filler cap. Another check for a reason you have that creamy, milky stuff could be a disconnected or non-functioning PCV valve.

But...drive the beast and let us know what you find out!

 

Yep i will, Still got quite a bit of things to fix from the p.o but nothing to big.Yes a bit of paranoia is to play, would hate to see 2500 bucks blown for nothing, it does have a slow idle on cold startup which im a bit worried about but thats for another day. Ill throw some cleaner in the tank and after a few days ill report back unless anything else has come up between then, and results of the leak tester since its already bought and shipped.
Thanks for the help

 

the steam/water out of the exhaust is just condensation that collected in the exhaust and pooled up in the muffler.
just like police cars that sit idling do. my crown vic will leave a stream of water out of the exhaust for 3 blocks when i take off.

 

the guys are right make sure you do the tests to make sure you actually need to replace the head gaskets . It's not a hard job but is a pain in the but .. Especially when things start breaking . Your gonna need to check the heads and block for trueness and may need to have the heads milled if warped . You will need new exhaust gaskets , probably bolts , intake gaskets , valve cover gaskets,thermostat gasket . You will need to remove almost everything on top and in front of the engine . Retime the distributor , plus likely many more small things that you break or find questionable along the way ... Soooo make sure it really has to be done because it's not fun on this era of vehicle !!

 

Amazon decided to be very nice and overnighted my combustion leak tester free of charge so i just finished the test when the truck was nice and warmed up and im glad to say the test past, no HG issues or cylinder leaks, my guess is when the PO did the oil and filled it 2 inches past the FULL line the oil was gettin places it shouldn't be and the smoke out the tailpipe is from the air injection that was broken that i fixed, trying to burn all the carbon and soot out that gathered up. Both issues are fixed! Thanks for all the help

 

2" of overfill on the dip stick could cause the counter weights of the crankshaft to splash oil up on the bottom of the cylinder walls. Excessive oil on cylinder walls may have ended up in your exhaust pipes and be slowly burning off.

 

If thats true, that would really explain why sometimes with the smoke it had the faint blue tint to it, I knew when it was blue it was oil burning off just wasn't sure the exact cause where it came from, so a mix between oil burning and carbon. Smoke is just about fully gone now after the oil and filter change
