This normally happens in vehicles that are driven in town  making short trips the  problem is the engine never gets enough time to evaporate the moisture from in side the engine after time this shows on the bottom of your oil cap and in side the block the best thing to prevent this is occasional  highway  driving  30 minutes or more at operating temp  i would not recommend  a engine flush

Don't get your system flushed .........do you frequently pull in and out of a garage? you might consider spending a little more cents to the gallon and buy chevron gas. their gas is more expensive because they have techron in it. it is a fuel additive that helps keep valves and rings clean. or you can buy techron . heat also removes any condensation build up in the gas tank and gas

    aaangie220 had it on the t. except its PCV valve . positive crankcase ventilation valve. you can also check it by unplugging it while the vehicle is running(located on the valve cover) putting your thumb over the hole and if no suction replace. probably about $4.00

Yeah dont worry about it. when you change your oil, as long as the oils hot, most condensation gets drained. the rest evaporates.

Yes the condesation is normal with that particular motor. there is an easier alternative. change the Positive Crankcase Valve (PCV). and buy a 5-minute motor flush quart from a parts store. then change the oil again. or take these parts to a different auto shop and start a fresh new relationship. a new auto shop will take your business and be reasonable about their prices too.

No oil pressure showing on guage.changed sending unit.removed oil filler cap and found I have good oil pressure


removing the oil cap does not tell you what the oil pressure is, as the oil you see is not under pressure. you need to connect an oil pressure gage and check the pressure separate from the car system to check pressure and compare to spec.

Why would oil and water leak out of my Lincoln navigator 5.4l engine


Worse case this could be due to a blown head gasket - however let not jump to conclusions. Where is the oil coming from and did you have it changed recently? Water is common from the A/C condenser and or over fill of the wiper fluid or possibly rain / bad oil change place that "rinses the engine" with water to get excess oil off. If you did have your oil changed / car serviced, take it back and have them check it. Maybe it's a loose oil filter or loose oil drain plug / bad washer on the drain plug. If you haven't have the oil changed recently, did you hit anything or did the car over heat recently? To see if you blew a gasket, check your overflow tank coming off the radiator. Pop the cap and look inside to see if you see oil (not dirty water / coolant). Also check if the car is blowing blueish smoke or excessive white smoke when you drive / rev the motor. If not, hopefully your fine. Post more details and you'll get a better answer. Good luck!

How to do a oil change


Pull the drain plug, change the oil filter, replace the drain plug. Add oil until the dipstick reads full. Start the engine and make sure the oil light goes out. Check for leaks around the oil filter with the car running. Recheck the oil level, add as necessary. Let me know if you have any questions and I'll do my best to answer them.

I have a 1999 oldsmobile Intrigue I have replaced the water pump and the thermostat, and coolant. the car is still over heating. Would air in the system cause this. What could cause this to happen?


Hi,
Check the coolant if there is oil in it and the oil cap if there is a whitish brown substance under the oil cap, means you have a blown head gasket and needs a replacement!
The radiator fins is already blocked, cause by dirt and years of using deep well water, needs to be clean, replace or overhauled the radiator.
The fan is not working and needs to be check thoroughly its motor or electrical system( relay, motor, rad fan switch sensor).
check all of that and tell us what happened.

Oil cooler under the intake plenum at rear top of engine is either bad or the gasket is gone. If you take oil filler cap off, you will see the paste on the cap. Are you going through coolant every so often?


Same as on my wife's 01.

it is normal to have that paste stuff on the underside of your oil cap and some on the tube the cap goes on. this is condensation it goes to the highest points in the engine alot of short trips makes this worse
if the oil thats drained out looks like regular dirty old oil then dont worry about it
if it looks pastie white then you got trouble

Water in the oil


If you check the oil dipstick and the oil is clean, not milky , then the problem is simple. Condensation under the oil cap is normal on vehicle that are not driven often or do not get up to temperature. If the engine is not used then the moisture in the air collects at the high point of the engine. You can leave the oil cap loose if the vehicle is to be stores for a long period of time,This should help .
