I have vapour / steam coming out of my oil dipstick tube on my 1.8 diesel Ford Galaxy, is this to do with a faulty / worn pcv unit. Would this also contribute to poor starting if the valve is faulty?


The PCV allows one way flow and vents pressure (gases) from the engine and sends them to the intake side of the air breather for re-introduction into the air intake system of the engine.
A non-working or stopped up PCV can cause a build up of pressure, which must vent somewhere. The oil dip stick is often the choice, especially if there is not a tight seal at the top of the tube.
White smoke or steam/ vapor usually means water is entering the internal workings of the engine. Head gasket leaks, cracked heads, and cracked blocks are the common source of such entry. Also water leaking into a cylinder will cause hard or poor starting as the piston is working against the volume displacement of the water. Upon cranking any water so leaking will be exited through the exhaust system and leave the vehicle as a white vapor out of the tailpipe.
Considering that most diesel engines have some "blow by", some water may be expelled out the PCV circuit.

Engin overheats , but it doesn't leak so why have to keep filling up with water and seen steam comin from like underneath the thermostat


Check your exhaust pipe when running. Do you see a lot of white smoke? If so, you most likely have a blown head gasket and are losing the water into the cylinders. This will cause overheating with no apparent leaking. If there is no white smoke, then you could be losing water from the "weep hole" under the water pump. This water often hits the engine block and evaporates (causing steam). Once you turn off the engine, the leaking often stops. Look carefully at the underside of the water pump for a small hole where the pulley shaft enters the pump. If you see traces of coolant (or signs that coolant ran down from the hole), you need to replace your water pump.

Well first off 2002 chevy blazer with 4.3 liter is losing water but no leaks. Then when it gets around 210 temp it begins to whine real loud and takes longer to shift from first to second. Engine light...


the check light means to SCAN it. (all cars, 1987 to now)
All posts are USA,

the water, coolant does lose coolant in 6 months of driving
but does not fast. so i presume you mean fast loss. like 1 day.

there are on 3 ways, (but inside leaks or outside are the 2)
so if no green AF on the ground nor on passengers toes (foot well)
then its internal.
way 3 is out exhaust tip. (seen as steam on a hot engine and said steam , smells sweat (glycol stench)
way 3 is just one more external leak , as steam>.....

that leaves, milky engine oil or the A/T (AUTO? TRANNY) the dip stick shows milky. (not pink/red. and clear but muddY)
the engine is first.
transmission is useless to any blown engine.
some newer cars the trans, has overtemp sensor that can force it to limphome, mode. 210 is not hot. some cars run 200f thermostats.

first off stop using the side expansion tank for diagnoses.
some lie. (eg. dip tube in tank bad,)
use the RAD cap test method., look into the RAD cap filler well.
is it REALLY full , dead cold ?
if not , bingo. huh? (my guess is you did this already) methods?
fiddle the side tank later, find out if you have air in the system.
first.

the tests for lost water are (no signs stated above)
are,
1: RAD leak down tester
2: RAD green /blue die tester

a new rad cap is cheap, me i just inspect the gasket, like this guy.
http://www.fixkick.com/Cooling-engine/capguts.JPG
see 17 signs of coolant lost there. and 24 causes.

http://www.fixkick.com/overheating.html

some cars have 2 failures. a partial clogged rad.
then one more failure, breaks the camels back (heat load)

One other way to lose coolant is that it only loses it driving
and you missed that?
are you checking the ground at each trip, end? and after coming back.?

i bet the 17 ways to leak finds its.
but the system holds about 12psi hot. if not , fix that first.
we just grab the top hose on rad,and go to self, yah got full pressure.
and temp.
if it does hold pressure, and there is a breach idling hot.
its easy to see, it will leak now at 12psi , so look/
if its not leaking externally then its inside the engine or out the exhaust tips.
LOOK NOW>
and if it overheats idling, all cars do of the fan is dead.
if it overheats, the fan must be active. if not fix that now.
the FSM book covers most the tests.

napa sells this ( finds cracked heads. or gaskets in head) or worse.
http://www.fixkick.com/overheating.html

same with this too

Steam coming from radiator but not losing water while driving


Doesn't seem to do something, will get you into
a not so good situation

Why are you using it vs: finding out the cause of the steam?

You either have a bad radiator or hose or some type
of leak being burned off on hot parts

Get involved & look it over

STEAM COMING OFF ENGINE


check top radiator hose goes to thermostat housing sound like its leaking if your engine leaking from left driver side on top of engine it has to be top radiator thermostat hose leaking.wait until engine cool down replace top radiator hose see if coolant leaking still occur if so you could have radiator leak.

I have unseen coolant loss with no overheating unless coolant gets to low. Can the coolant loss be through the intake manifold gaskets? My vehicle is a 2002 Chrysler 3.8 in a Town and County van (No rear...


it is unlikely that it would be leaking through the intake manifold gasket as such, but loss of water is usually caused by leakage, but they are not always easy to find, depending how much water you are losing as to where it is leaking,sometimes if it is a leaking water hose at the clamp it will only leak when you first start the engine & stop when the engine warms up ( very hard to detect) it could be the head gasket is starting to blow check the exhaust pipe when the engine gets up to normal running temperature to see if there is any steam coming out if so that may well be the problem......hope this helps......cheers.

The temp gauge reads correctly for a while then it starts going from cool to hot faster the water can change temp. I have changed the sensor


try the thermostat, located on the top radiator hose. top side of engine. also does it steam?? does it lose water but no leak, does the heat blow hot? if your heat isnt hot and it steams and loses water you may have a cracked head or head gasket. if you have heat, doesnt lose water and doesnt steam it may also be your water pump. most pumps will leak visibly from the weep hole when running

My son's 1997 honda accord starting smelling hot, like something burning. He saw the temperature gauge was getting hot, so he pulled into a parking lot and opened the hood, there was steam coming out from...


I have had a similar problem with my son's Accord. You are lucky that your son knew to stop immediately, this happened to my son and we ended up having the head rebuilt.

A leak may exist but not show up until there is adequate pressure or, you may have a blockage that caused excessive pressure.

We once had the radiator leak which was nearly undetectable in his Accord, check for moisture in the trough where the radiator sits by looking down the inboard side of the radiator with the hood up. You may need a flashlight. Radiators are available at auto parts stores for about $100 and easy to replace. Replace the thermostat, cap and as many hoses as you can at the same time.

Another problem we had was the radiator cap had come apart and leaked periodically.

If the thermostat stuck, this could have caused a temperature and pressure surge explaining the now-you-see-it-now-you-don't leak. A faulty fan, or fan switch could also cause a periodic temperature surge.

The leak could be coming from the thermostat housing which is on the passenger side of a 4 cyl engine, or from the upper or lower radiator hoses or the two heater hoses. The water pump is on the drivers side and connects to the thermostat housing through a metal pipe with O-ring seals.

Lose of water


Hi,

One possible explanation is that the leak is small and the water escapes as steam. This then would lead to no immediately visible water leak under the vehicle and being small, the coolant system is still capable of preventing an overheat. Most likely spots would be the junction of the radiator hoses either to the radiator or to the engine side. One possible way to check is use your Toyota as you normally would but before shutting down the engine after a long drive, pop open the hood and check where steam or water might be leaking.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
