Check the base of the oil dip stick (ON THE BLOCK SIDE / under the car)

A crack at the base of the dipstick tube will care 2-3 quarts of oil spillage.

The only fix is to replace the oil tube on the bottom end,

all turbo engines have a oil line to the turbo. If it is not getting oil the turbo will burn up and have to be replaced. Change your oil and filter to start with.

SOURCE: Blue smoke out of tailpipe both at idle & acceleration

Gary,
The initial oil leak will most likely be attributed to a worn seal or gasket. I'm sure your aware of this anyway. My concern is that the additives, although advertising a sure fix, may have made your problem worse. I personally don't believe you can buy any product that will fix faulty seals and gaskets as you drive. Typically we as drivers do not pay attention to a fluid leak in it's early stages. There might be a chance that then would be the time that these "gasket in a can" fixes would treat or slow down the leak. What will ultimately happen is the gasket goes bad anyway. Most of us don't notice the drips until they're all over the driveway. You see, if you were adding these things and not actually putting in the proper viscosity oil during this time. The oil got diluted and internal engine component wear may have been accelerated.The internal oil passages can clog and bearing surfaces can lose they're critical tolerances. In many cases causing low oil pressure. Your engine's oil pump pickup screen may be partially clogged with sludge as well after the motor flush knocked all the gunk into the pan.
As for the smoking, the oil rings on one or more pistons probably have broken. Your engine's pistons will have a couple of "rings" that seal the piston in the cylinder. There'll be a set of compression rings and an oil ring. The bottom ring is the oil ring that keeps excess oil out of the cylinder. What happens is the oil ring breaks and allows the engine oil up into the combustion chamber. There it's burned producing your cool James Bond smoke screen. Unless you plan on rebuilding the engine, chances are you'd be better of replacing it with a used one. It's usually much less expensive that way.
*personal experience*
My vehicle at the time was a 1990 Acura integra w/200000 miles on the engine. One day as I was happily driving down the road....poof....James Bond!.. Car lost power and I couldn't see for blocks behind me. Didn't need GPS to find my house that day, just had to follow the cloud. This particular vehicle actually never smoked prior to that day. Anyway, I pulled the engine, and took it apart. Sure enough, as I had feared, the oil ring on #3 piston was broken. Ultimately I replaced the engine.
Good luck with yours, and I hope this helps.

SOURCE: engine blowing oil from oil filler cap

I had the same problem. I changed the pcv valve and checked the hose. It still did the same thing. Then I checked the metal tubing that the hose connects to and found it was full of hardened gunk. I sprayed PB Blaster into the tube let it soak for awhile. Then took an old choke cable, put it on a drill and ran it into the tube like a drain snake. It took a while of doing this over and over but eventually got it cleared out. Now, no more oil all over the engine and hood compartment.

Transmission dipstick keep popping up 2004 chevy trilblazer


Is it crankcase pressure that causes it to pop-up? If so, check crankcase ventilation system/pcv. It might be possible that you have so much crankcase pressure, that ventilation system can't handle it, then the pressure gets out anyway it can.

On a warm engine, at idle, if you remove oil fill cap, is there smoke coming out?

Why is it blowing off oil cap


Too much crankcase pressure for some reason? I've seen a melted piston cause so much crankcase pressure, it blew the pcv valve out of the valve cover and sprayed oil all over the engine compartment.

Is your oil cap threaded? If it is threaded, I don't think I've seen one of them blow off? Also, check crankcase ventilation system, pcv where applicable. Do you have a lot of blow-by from crankcase? I don't know your year--make--model or engine size?

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

Where is the oil filter on the 2010 gmc terrain 2.4


The oil filter on the 2010 GMC Terrain is located in the engine compartment. You'll need a short depth 1-1/4" socket wrench to loosen the cap. The cartridge is in the canister under the cap.

What this means is your engine has alot of what they call blow by which means alot of crankcase pressure about all you can do is you can try like engine restore as a cheap attempt to help reduce some blow by or rebuild/replace engine if you try the restore change oil and leave it about 1/4 to 1/2 quart low on oil and add your can of restore if that works you have to do it at every oil change.Restore helps rebuild compression by filling in minor scratches in the cylinders and gives the rings a better seal in the cylinders.It usually takes 300-500 miles to make a noticeable difference if you dont notice it by then rebuild/replace engine..
