SOURCE: have oil in my radiator fluid reservoir tank (1996 v6 3.8)

Twice in two years now my Saab 9-5 has had a pin-hole in the oil cooler, which has caused oil to flow into the reservoir. A way to tell is if coolant/oil is coming out of the reservoir cap. The reservoir cap is rated for the pressure of the coolant system, which is significantly lower than the oil pressure. When there is a hole in the oil cooler, oil will be forced out at relatively high pressures, causing the reservoir to fill and then over pressurize and spill out of the cap.

SOURCE: 95 chevy blazer tank removal

Park the vehicle in a place where you’ll have plenty of room to work. If you have access to a lift, that would be great.
Relieve any fuel pressure by removing the fuel cap. Disconnect the negative battery terminal. Pre soaking any required bolts/nuts with WD-40 prior to the job will help also. There are 3 lines and 2 electrical connectors to be removed from the fuel pump, and the filler and vent hoses that need to be removed from the back of the tank. There was also a small hose on the front part of the tank that needs to be removed, but we didn’t see it until we actually started lowering the tank. Just remember where everything hooks back up. Label the lines, if needed take picture with your cell phone.

Start by removing the skid plate, Once the skid plate is off, you’ll have access to the straps that hold the fuel tank on. The forward ******** the Blazer will pretty be rusted and not very stout. It's basically formed as a strap that ended in a threaded bolt and in most will end up breaking trying to remove it. Supported the tank with a floor jack with a transmission removal assembly on it.

You easily fixed the broken strap problem by welding a bolt to the strap. Once all the straps were loose, lower the tank just enough to get better access to the lines and connectors leading to the fuel pump. There is not much room to get in there on a Blazer. 
Once the tank is off, it’s a good time to look around in that area to see if there are any other problems that may need to be addressed.

If you are going to replace the fuel pump here's how to do it. Before removing the fuel pump, be sure to clean off all the junk that has collected around it. 
Replacing the float and sending unit is fairly simple. Just pay attention to how the old parts are removed, and install the new parts in reverse order. Be sure to get the wiring routed correctly and install the new seal that comes with the kit. The sock filter on the bottom of the pump was just a little bit clogged, so we made a trip to the auto parts store to get a new one. Luckily they had one that would match up. 
While we had the tank off, siphoned what fuel was in there and cleaned out the tank really well. 

The installation is basically just a reverse of the removal. Be prepared to take quite a bit of time for this project. It took much longer that I expected. Somewhere around 6-7 hours, but that’s including several little problems, getting propane for BBQ lunch, and making a trip to the parts store for a new sock filter for the bottom of the pump. And Mom and dad showing up.

Good luck and hope this help

SOURCE: water in crankcase

Most likely a blown head gasket. Don't run the motor until you get it fixed. Can also indicated cracked head or block. Hopefully just a gasket.

What causes my truck to lose water, and what makes water get into my engine oil?

the water can get into the sump oil from pin holes in the timing case behind the water pump impeller
if you have water in the sump oil it will be a dirty grey color and the filler cap will have water droplets under it
If the oil is normal color then the loss could be from rusted welsh plugs
pressure test the cooling system to check for leaks

Why water going out from the reserve tank in my batfinder

Your coolant system is leaking water.
Look under the vehicle for signs of the coolant whatever color it may be leaking down the engine.
If you have an automatic transmission, look at the fluid to make sure water is not leaking into the transmission via the cooler in the bottom of the radiator.
Check the tightness of all hose clamps on every rubber hose. Check the condition of the radiator cap and if it is older than 5 years, replace it with a new one anyway.
Take the overflow hose off the radiator and try blowing through it into the reservoir..if the system is dirty sometimes coolant is blocked from going into the reservoir when the engine heats up and therefore is dumped on the ground.
Check the reservoir for cracks.
Check it's cap if this is separate on your vehicle.
Please get back to us with your solution to this problem as it may help someone else in the future.

I have what looks like oil in my coolent and if you touch it and then take your dip stick and whip your dip stick on another finger the stuf coming from the coolent reservoir and what comes off the dip...

Some factory installed so called lifetime coolants when they break down from age and heat form what looks like an oily sludge, but it is not oil. Drain and power flush the entire cooling system, clean the coolant tank with a pressure washer and refill with any of the new coolants out there. If after the system is flushed and refilled this occurs again you have a leaking head gasket.

I changed the turbo now white smoke coming out of my exhaust

This seems to be a symptom of a blown head gasket.
White exhaust smoke is an indication of water / coolant in the exhaust. The car running sluggish and using lots of fuel can be caused by compression loss.

Look at the coolant level color and smell (with cold engine - don't open the high pressure reservoir with engine hot as hot coolant may spray you in the face). If you have a blown gasket, the coolant color may become brownish and it may smell bad or the level will get lower even if you have just refilled the cooling system.

What you can also check for is bubbles in the reservoir. With engine cold, remove the reservoir cap. Start the engine. Try to rev the engine (or have someone do it) and observe if there are bubbles in the reservoir tank. If you see lots of bubbles, you have a blown gasket.

My boyfriend has a 91 Toyota 4runner v6 SR5. He has replaced the radiator and thermostat. Also he has bled the coolant system several times. The truck is still losing coolant. If he drives the truck...

When engine completely cools remove coolant from overflow reservoir to the cold mark on the reservoir which is the lowest mark on reservoir. If you continue to loose coolant you may have busted block.

Found oil in my water reservoir its like milky thick and creamcolored kinda brownish

Sounds like oil. 1.9 SOHC engins have a head defect so most likely you need to replace the head 99% of the time. 1%of the time you need a new head gasket. The good news is that heads for these engins are not to expensive. Just check out ebay and see what I mean.

Radiator flushing , brownish coolant in reservoir

That brownish color is caused by oxidation(rust) of the waterways in the engine block. Dont worry, your engine wont rust through. This is normal on any car. Just flush it out until the water runs clear. Refill with water and use a good antifreeze as well as it contains rust inhibitors.

1999 chevy lumina has water in the oil

This is typical of a bad head gasket. The gasket is shot, allowing the coolant to mix in w/ the oil.
