There is no head problems or intake problems with that vehicle.

What has happened is your head gasket went out on you and you need to replace it.

Why water mix with oil in my Honda odeyssy


If coolant is mixing with the engine oil it may be caused by a bad intake manifold gasket/bad head gasket/cracked cylinder head/ internal crack in engine block

Oil in radiator , but there is no oil and water mixing in sump


I am assuming its motor oil and not transmission fluid, right ?
You can have a leaking intake gasket or head gasket and get oil in the coolant without getting coolant in the crankcase.
Same thing opposite. The bigger the leak, the better the chance of getting both at the same time.

Can not be water pump, because that has a vent hole to the outside, and does not at all allow access to crankcase or cylinders. Oil cooler is also unlikely because oil is under more pressure than the water, and it would not get into the cylinder.
Water in the cylinder means up high.
That means head gasket or cracked head.
You can tell with a leak down test.
You borrow the gauge from a place like Autozone, and replace the water reservoir cap with it. Over pump it, about 30 psi. And watch for leaks. If same cylinder keeps filling, then you know where the bad gasket or head crack is. Diesels often crack heads. Not hard to do, but new head is not cheap. Probably $500 for part, $400 labor.

Car runs hot water going in the oil


These are symptoms of the following
1-Blown Head Gasket
2-Cracked head
3-Cracked cylinder wall

it could be one or all three.
This is serious business, and should not be driven untill you know for sure.
Water in the oil will damage engine bearings if allowed to leak into the crankcase

What's the difference between a blown head gasket and a blown intake gasket?


The head gasket goes between the block and the head, and seals the combustion process, and cooling water, and (if oil is pumped obove the heads to valve components) oil pressure.

Intake gaskets seal between the intake manifold and the head, and seal against intake vacuum, and in many cases, coolant.

A badly blown head gasket will so destroy compression in the cylinder that you can hear uneven cranking as that cylinder comes up on compression, kind of a “whir, whir, WHIR, whir, whir, WHIR, whir” with the capitalized whir being the engine spinning much faster due to no compression holding the starter back.

You will never be able to hear a problem with an intake manifold gasket until the engine actually starts to fire and/or run.

4.3L engines are notorious for blowing intake manifold gaskets, not head gakets. Usually the rear coolant ports on each head.

In some cases I have seen blown intake manifold gaskets cause a milkshake in the crankcase inspect the lower intake gaskets coolant passages at the end of the cylinder heads for damage. I would suggest a compression test and a cylinder leak down test befor further tear down.
