Changed spark plugs on a 2004 mazda found oil in the pistons #4#3#2#1 was no oil in it


You didn't find oil in the pistons, you found oil in the spark plug tubes. This is fairly common on older engines. Over time the seals in the valve cover begin to leak around the spark plug tubes. Oil then works it's way into the tube and settles in the bottom.

There is an easy fix. Simply replace the valve cover gasket.

Wipers stopped working, car screeching, oil issues


the smell could be oil leaking on to the exhaust from the rocker covers.(common problem in Subaru because of the side mounted pistons. Engine stop oil leak might fix other wise will have to get tappet cover seals replaced as they crack over time from the heat) easy enough fix. a tell tale sign is signs of engine oil stains or signs of oil dripping on to the exhaust(can locate by looking under the front of the car at the bottom of the engine itself) and this is probably the cause of the engine knock due to low oil.it will continue to leak till the problem is fixed

SMELLED OIL IN CAR VENTS. LOOKED AT COOLANT RESEVOIR AND IT HAD OIL IN IT. OIL DIPSTICK AND OIL CAP LOOKED CLEAN, SO I SUSPECTED UPPER INTAKE MANIFOLD LEAK. WHEN MECHANIC CHANGED MY VALVE COVER GASKETS...


If the leaking gasket was a long term problem, the bearings may have been ready to fail. A standard procedure when replacing any gasket that has possibly been leaking anything into the engine is to do an oil change. If I read your question right, sounds like this wasn't done, if it was, then it would be hard to fault the shop. Any coolant or fuel that leaks into the oil will degrade the lubrication properties of the oil possibly to the point of metal to metal contact causing the bearings to fail.

My engine is smoking and smells like burnt oil? maybe. there is a gear symbol with an ! next to my park/drive on the dash board


Perhaps oil has leaked onto the exhaust manifold.
Check the oil pressure also.

Oil LeakOil leak, probably valve cover gaskets need replacing or just tightening. Also if it started suddenly after an oil change, the filter may be leaking, or you spilled oil on the manifold.
This MY & others had problems with both the cranshaft oil seal. The rear one leaks onto the exhaust and can make a horrible burning oil smell, notably when you stop after a long drive.
Head Gasket
Outbacks up to 2001 have issues with head gaskets, its a widespread problem. If the smoke is white and smells sweet it is coolant leaking into the pistons via a head gasket. Replace the head gasket before it fails. If you blow the head gasket it will ruin the engine.
Cam Seals
It is most likely the cam seals dripping small amounts of oil onto to the bottom of the engine block. When the engine warms up, it will burn the oil off.

Smell smoke


There is most likely an engine oil leak that is leaking on the exhast that runs accross the bottom of most toyota engines. Valve cover is common

Burnt Oil Smell


Check carefully around the valve covers, this is the area that leaks most frequently occur, and being located next to the exhaust manifold can easily cause the burning smell. There is a very easy to replace gasket under the cover. Other possibilities, shop or you when changed or added oil spilled a bit and that has worked down to the exhaust manifold and is causing the burnt oil smell. Last possibility is that you do have a slow leak on the underside of the engine that is blowing back onto the exhaust system causing the smell.

My engine is smoking when i start engine on mornings


sounds like valve guids are wearing out.. drying out and cracking. only fix is to replace them. or try a heavier oil. sometimes that will help depending on the severity of the problem.

The complete loss of oil suggests that you might have a piston problem!

First, check the compression on all cylinders; all values should be within a range of 10% from highest to lowest. Typical value about 140 psi.

One cause could be a blown piston or rings, allowing pressure into the crankcase, and blowing oil out of the filler pipe - very fine and barely visible, not spouting. You might feel the pressure pulses from the damaged or leaking cylinder.

If one cylinder has zero pressure, it's more than likely the cause of the problem. Do a wet compression test (pour a little oil into the cylinder immediately before connecting the compression tester - it usually seals any leaking rings for a little while) and if it holds pressure, that points to the rings; if no pressure again, that points to the piston.

Let us know the compression test results.
