Wow no year, GC.
the side coolant water expansion tank.
that means 1 of 3 things.
1: if oil is red/or pink the a/T cooler is ruputured.
2: brown oil is engine, bad head gasket or far worse.
3: Jiffyboobs put oil in the rad. (common there)

I have water in my oil cap but not on the dipstick. What could be wrong?


If your oil looks normal and you're only seeing this oil in the filler cap when the engine is cold or barely warm then it is probably just condensation from humidity in the atmosphere. Normally that steams off when the engine is at operating temperature for 10-15 minutes. If you have dropping coolant levels, milky oil or other signs of water actually in the oil that would be more serious.

Tip

Oil Sludge In Rocker Box and Pipes


Oil sludge found in Air Cleaner, replaced PCV and filter and cleaned and had to replace filter in 6 months due to yellow oil sludge

Yellow sludge found in system, cleaned hoses replaced filter and PCV and six months later had to repeat process
Posted by xxxx on
Oil sludge can be caused by a few different things including a clogged pcv valve, which you say you have changed. I don't think you have head gasket/head problems as you say you've been using the vehicle for 6 months.

However, do check your oil dipstick and see if the same sludge (also known as 'mayonnaise') is on it. Mayonnaise on a dipstick is a symptom of a defective head gasket that is allowing coolant into the oil system.

If your vehicle looses/uses coolant this may be a sign of a faulty head gasket/head.

Very short- repeated - journeys can allow sludge to form , simply because on short journeys the engine does not reach its normal operating temperature. The engine is 'cool'.

It can also be caused by a faulty thermostat. If the thermostat is jammed in the open position it can take a long time for the engine to reach normal operating temperature. Other than changing the thermostat (maybe for one that opens at a higher temperature - a ' winter' thermostat) there's no practical way of checking it. Replacement is the easiest and cheapest option. It's not a difficult job.

It's not unknown for a thermostat to have been removed by a previous owner (for various reasons..). If you're going to check if there's a thermostat there - replace it anyway.

If you're not losing/using coolant and there's no mayonnaise on the dipstick it may well be due to repeated short journeys where the engine doesn't reach normal operating temperature - or the thermostat.

The reason that sludge - or 'mayonnaise' forms is because of water content/moisture. For every gallon of fuel your vehicle uses in the combustion process, it produces 1 gallon of water. The water vapour will condense in the coolest place - and in the engine this is the rocker box and pipes. If the engine is at normal operating temperature the sludge should not form in modern engines (it happened commonly on engines in the 70s and 80s..).

Another cause of sludge - though it is black sludge - as opposed to a creamy colour, is an egr valve that needs cleaning.

How to rid water from engine


That would depend on where the water is ... in with the oil or in the gas tank, etc. If in the gas tank, use 'dry gas' which can be found at any auto supply store and most hardware stores. Follow directions on the bottle and that should do it. If the water is in the oil, the best thing to do is take it in for an oil change and mention that you think there might be water in the oil, although the oil "should" get hot enough when your engine reaches it's normal operating temperature to vaporize the water and the water should vent.

Overheating indicator flashes, but has oil, water.


Hi. The contacts in the Coolant bottle get contaminated and then don't pick up the water level. Brige the contacts at the water botlle and start the car, if the coolant/temp light behaves for 5 min or so after starting the car, then change the coolant bottle/resevoir.

Oil in the radiator


old post



  1. if you do the service on car, then that is bad. (oil in AF)


  2. if done at JIPHPYboobs. it can be just oil put there.




it will get worse if #1

if #2, go to any real auto shop, ASE shop and get a full flush and fill

to get that gunk out of your engine.

or ask them to do the rad leak down test or exhaust fumes in RAD test.

if all tests pass , its a long distance runner... if not , not.

Oil in the radiator


That is likely coolant that has broken down and appears to be oil but it is not. Remove the tank and flush it out and then flush the entire cooling system.

How do i prime the oil pump in a 99 e250 5.4L


Oil pump is self priming. You do not need to prime it. If not showing oil pressure, the sensor is probably defective. Make sure oil level is not low. If the vehicles water temperature gauge shows normal when running then oil pump is working fine. If it goes to the overheat mark then you may have defective oil pump, which is rare. Most temperature gauges go past the middle when you first start up but then drop back to normal once the engine thermostat opens up. Hope this helps.

What is the check gauges light


CHECK GAGES light (1) indicates a potential engine failure(low oil pressure, low coolant, coolant overheating) has occurred.
· Check gages and shut down engine. Gages should read as follows: Oil pressure 5 to 10 psi (34 to 69 kPa) at idle; Water Temp gage below 230 degrees (110 C).
· Check engine oil level (Para 2-11) if OIL PRESS gage indicates low reading. Check coolant level (Para 2-11) if Water Temp gage indicates high reading. Notify Unit Maintenance if levels are low.

If CHECK ENGINE light (2) is on, check engine oil pressure gage (3) and water temperature gage (4). If both indicate normal, proceed with mission and then notify Unit Maintenance. If either one does not indicate normal, stop engine immediately and notify Unit Maintenance
