WATER STILL IN THE OIL!!!!!!!!

[Kerny]

AFTER CHAGING THE HEAD GASKET, NEW HEADS, MANIFOLD GASKET (NOT VALLEY PAN GASKET), TIMING COVER, TIMING COVER GASKET, AND A SHIT LOAD OF RTV SILICONE I STILL HAVE WATER IN THE OIL. IS THERE ANYTHING ELSE I COULD BE MISSING OTHER THAN IT BEING A CRACKED BLOCK??? I AM RUNNING THE 460. WHEN I STARTED THIS PROJECT IT STARTED OUT WITH A CRACKED HEAD, I REPLACED THAT NOW HERE I AM.

How much water in the oil,is it milky or actually adding volume to the oil pan?

[Kerny]

IT LOOKS LIKE A CHOCLATE SHAKE.

[hoolign]

yeah,but are you gaining alot in volume

[Kerny]

not to sure i got dicouraged and went to bed before i checked how much volume was in the engine.

[hoolign]

If your wondering about a cracked block run the water for a while without starting the motor,see if the level in your pan comes up.

[Kerny]

it seems to me that it only does it under the pressure when the engine is running

Kerny:

[Kerny]

can i do a leak down test????? :confused:

[hoolign]

You can buy a leakage tester at most auto parts stores.

I would be very suspicious of the block. If one of your heads cracked more than likely the engine was overheated at one time. It may not leak when engine is off and cool. The heat from the engine tends to open up a crack as the metal expands. sounds like you covered almost all the other possiblities. I sure hope it isn't you're block but it sounds like you may have a crack between water jacket and cylinder. When you had the heads off did you take the opportunity to check the cylinder walls for cracks. They are not always visible to naked eye. If you find it is the block and want to limp it through this season. K&W block seal works charms. I know it isn't the right way to fix it but like I said it may allow you to make through the season and tear down in winter. Sorry to hear the bad news and we'll keep our fingers crossed for you.

How would you use KW-Block seal in a open system...such as a Jet Boat?

[Kerny]

bilge pump only $8.99

[126driver]

If you haven't already, change out the oil and fire the engine back up. You won't like what you find on a teardown if you leave that milkshake in there for any amount of time.

[Snowboat]

You did not mention the head bolts or studs. Plenty of sealant on those? Have you run it without water to the headers?

[eliminator777]

Permetex Hi tack,Loctite teflon,Plain old Teflon pipe dope to seal head bolts.Problem is if you didn't pressure check any thing You went to a lot of work for nothing.For your own sake don't run it with water in oil.The bearings tend to gall.460 fords tend to crack heads.The Blocks don't. :D :D :D :p :p

[Kerny]

nope i did not put anything on the head bolts cry

[Snowboat]

You need a Ford guy to step in. Many Chevys need sealant on the head bolts, because they go into the water galleys. Don't know jack about Fords.

[Thunderbutt]

Did you change the old oil before or after you put in new gaskets. A lot of time when you pull the heads you night get water in the block. So preasure test with water or air if you increase with water or, here air leaking out you have a problem. Vary little water makes the oil look shitty after you run the motor.

[TahitiSteve]

The lower head bolts on my Ford 302 go into the water jackets, no idea about any other fords though.

Like Riodog says ,429/460 head bolts don't go through waterjackets,you just oil them at installation.You didn't mention what type exhaust manifolds you're using.If you run the log type,when the gasket between the manifold and riser goes south, water can enter through the exhaust valves at # 4 and # 8 cylinders.To remedy this problem it's a good idea to replace the standard type gaskets with aluminum ones and rtv silicone.

So I guess my three rusty wet head bolts would explain why I have water in my oil! :confused:

[396_Z]

Did you check your new heads and/or block to see how true the sufaces are?
Not a likely situation but you could be far enough out of flat that the water (under pressure at speed) is leaking past the gasket into an oil galley or passage.

[Rock-it man]

I had the same problem was too much water pressure was leaking under the head gaskets try a relief valve ROCK-IT MAN

[waterloged]

This KW-seal stuff, Can you use it on a alcohol motor?

[OMEGA_BUBBLE_JET]

I'm sure you could. I have personally only used it on diesels and gas engines but I see know reason why it couldn't limp an alcohol engine by. Just remember it is not a permanent fix. But it might get you through the rest of the season.

Like HammerDown said, How do you use K&W Block seal in an open line jet boat..?

[HOSS]

Are you using the same Intake? Is it an old aluminum one? Maybe the water has rotted through it? Do you have insurance? Do you have matches?

[wfodude]

To use K&W get a bilge pump and set up a recirculating system in a bucket of water. It will get warm fast but circulate the sealer just fine.I personally use ceramic seal and it does work wonders.

Kerny, The info aboutpossible heat damage to the block when the head cracked has merit. another area that often gets overlooked is the fastners. Head bolts/ studs don't last forever. The torque that is applied is actually "strech". When the head cracked, these bolts were streched to the limit, and then over heated along with the rest of the engine. Once they lose Tensile strenght they will no longer apply enough pressure to seal the heat gasket. On BBC motors I usually "circle" the water ports with a small bead of sealer, to prevent leakage. At this point, a VERY close inspection of the head surface, block surface, and the gaskets themselves(including intake) at teardown MAY make the problem obvious. Did you replace both heads? or only one?... Moneypitt

[dego red]

For what it's worth, I had the same problem with my 351. After chasing the intake and head gaskets, I found a cracked exhaust elbow that was putting water into the back two cylinders. red

[1FastHallett]

i had the same probem with my big block chevy. did all the things you have done including a new water press valve. turned out to be a warped intake manifold. i put the new manifold on and i havnt had the problem since.
