It vents blow by cases from the crankcase back into the engine its part of the PCV (positive crankcase ventilation system). If it is split not a big deal hardware stores carry lots of hoses like that there about 50 cents per foot.

My super bronco CRT /w reverce does not have oil cap dip stick ?


Some people have tried several methods to see the oil when it seems nearly invisible.
One is to drill really tiny holes in the dipstick , and the oil will fill the holes where it is at that level.
Check with your local Troy-bilt dealer to see if a dipstick-cap is available,
God bless your efforts.

Ford 5.4L 3 valve motor has vacuum in the oil pan and will not run with the fill cap off.


The only vacuum being pulled, is the hose from the valve
cover (PVC) hose ,I believe, to the throttle body area

The reason you have a crankcase vacuum so high on the other
valve cover & oil fill cap, is that air can't get in to replace the air
drawn in behind the throttle body

eg: you have no air coming in,find out why

I think the air in comes from the ducting around the MAF Sensor
area in a 1" plastic or rubber tubing to the cover where your fill cap is

My Lincoln is like that

I have been around 5.4 fords I just haven't googled a picture of yours,you can do that or look over your truck

The vacuum amount or flow rate is controlled by the PCV valve
hoses & system design,so you have no air coming in the other
cover or little,thus high crank case vacuum

That said-- what your doing is NOT a test & in some motors will set
a MIL Lamp & OBD Codes

Once the oil cap if off, you have an open hole for air to rush in & back to the pcv & intake,so leave it on when the motor is running

Opposite your theory

It dies because with the oil cap off, your letting in unmetered air
that goes into the intake,cylinders & out the exhaust & you loose
fuel trim control,as the oxygen sensors & pcm are confused

Im trying to empty some oil from my 1996 nissan sentra gxe, i accendently overfilled it. where do i empty it from and how?


This will be a 2 person operation so be ready for this. It works great!!!!
If you have a shop vacuum, turn it on, remove the oil cap and cover the oil cap hole. Have some one under the vehicle and take out the drain plug using a 14mm wrench or suitible tool. Have a drain pan under the hole (oil pan). When ready have the person holding the vacuum remove the hose briefly to drain the oil. When you fill enough has drained then reinstall the plug and check you oil level. If more needs to be drained then repeat above steps till you achive you correct oil level.
besure to always replace drain plug washer/ gasket so you do not create an oil leak.
Hope this helps solve your concern.

I can not find my oil cap in my 1971 Ford mustang Mach 1 where would it be at?


Look on the drivers side front of the valve cover and you will see the oil fill cap. It is the large cap with a hose connected to it. Here is a photo of the oil fill cap located, lower part of photo dead center. clay58_51.png

I want to check the engine oil level for previa 2.4 petrol 1995



OIL LEVEL CHECK Every time you stop for fuel, check the engine oil as follows:
  1. Park the vehicle on level ground.
  2. When checking the oil level it is best for the engine to be at operating temperature, although checking the oil immediately after a stopping will lead to a false reading. Wait a few minutes after turning off the engine to allow the oil to drain back into the crankcase.
  3. Open the hood and inspect the level of the engine oil tank. The fluid level on the tank should read between FULL or F and LOW or L.
  4. If the level is below the LOW or L line, remove the cap and add enough engine oil to reach the FULL or F line. Fig. 1: Fill the engine oil tank located under the hood first 90911p07.jpg
  5. Install the oil cap and hand tighten.
  6. After filling the oil tank, remove the engine access hole cover on the drivers side. Fig. 2: Make sure the oil tank is to the F mark 90911p15.jpg Fig. 3: The oil dipstick is located under the driver's side engine access hole cover 90911p83.jpg Fig. 4: Place your finger through the hole and pull straight up to remove 90911p84.jpg
  7. Remove the engine oil dipstick and wipe it clean.
  8. Reinsert the dipstick, push it in as far as it will go, the pull it out and look at the level on the end.
  9. If necessary, insert more oil through the oil filler cap next to the dipstick, this will completely top off the system. Fig. 5: The oil dipstick has two markings for level check 90911p85.jpg Fig. 6: To fill the crankcase, remove the engine oil filler cap 90911p86.jpg prev.gif next.gif

I have a 1985 s10 blazer .. i drained the oil and replaced the plug, and replaced the oil filter .. however, i am unable to remove the oil fill cap. it does not pull out nor unscrew .. it does hand...


If you have any other fittings on the valve cover (pcv valve, breather tube etc) you can put a hose into the valve cover through that hole and fill it. (slowly...most have baffles inside). I have seen engines filled through the dipstick tube also (takes forever though).
Once you get oil in there, bring it to a shop and have someone show you how to get the fill cap off so it is easier next time.

What is the little hose called that runs into just below oil fill


If it is a 3/4" hose similar to a heater hose, it goes to your air pump system. it can be replaced with standard heater hose.
