CS-452VL leaking bar oil into combustion chamber?

After it sits for quite awhile, it won't crank. I find oil in the combustion chamber. If I flush it out and dry out, it will start and run. Fix?

Taking that the equipment is a chain saw (cs-452vl means nothing) from the bar oil statement, the only possible connection between the bar oil container and the combustion chamber is by way of a vent tube to the inlet manifold or air filter
possible fixes
clean out the passage under the bar and chain that is blocked by the saw dust residue
drain the oil out after use

SOURCE: 2005 F350 DIESEL,WAS RUNNING,SHUT IT SHUT OFF,WON,T START

first check the oil and see if it is full. the injectors are fired by oil pressure so check those things first.

SOURCE: quits while driving replaced many suspected parts

try this, the next time it quits leave the key in on position and get a broom stick and go to the passenger side of the car. About straight in at the back of the door ,reach under with the broom stick and tap the plastic gas tank a few times, have someone try to start it or go start it yourself. Mine did this even after the garage checked it out and cleaned the tank. Come to find out dirt settles around the fuel pump and clogs it. They just blame the pump but in my case the pump was fine. I was told Alero used a very small fine mesh in the sock that goes in the fuel pump and they clog up. But most of the dirt was around the plastic guard around the fuel pump. See if this works and let us know. Good luck

SOURCE: 1997 jeep grand cherokee cranks long time before starting

generally your problem can be traced to a faulty anti-drainback valve in the fuel pump. After sitting for an extended time fuel must be re-filled and pressurized before engine will start. Second primary cause is a leaking fuel injector which does the exact same thing from the other end of the system but, this is also accompanied by a puff of smoke after starting.
Other causes can be low comrression from engine wear, or, a weak ignition coil but these are far less common.

SOURCE: i have an oil leak in a spark plug chamber how do is fix it

depends where the oil came from.of it has leaked down from a valve cover gasket,that is not hard to fix.if it a leaking valve seal that is expensive and if the head gasket is leaking,expensive.look at the outside edge of the valve cover,and check the edge for oil.if there is alot of oil,by the time the plug is unscrewed oil can go inside.the oil would burn off,so if there is oil inside it is dripping down probably from a valve seal.take off the valve cover and inspect the seals they are probably no good.there are 2 seal sets,one is in the valve cover,and that results in oil on the outside of the plug,and the actual valve seal which results in oil in the inside of the engine.

Have 2005 pt crusier 2.4 turbo

Its oil. Oil is leaking past the valve seals, letting oil seep into the combustion chambers when sitting. This is a pretty small leak that shows its ugly head when starting it up after it sits a bit. Keep driving it, not a major problem. Just keep an eye on your oil level.

Have to put coolant in all the time , no leaks visible, now would not crank

Run a compression test, sounds like a blown head gasket, warpped/cracked cylinder head. Coolant is going through the combustion chamber out the exhaust and into the crankcase/ oil.

Would a defective fuel pump cause white smoke from exhaust?

probably not. White smoke in the exhaust is a sign of either coolant or oil entering the cumbustion chambers (cylinders). Faulty fuel pumps usualy stop delivering fuel to the engine and it won't run at all.

My 1984 corvette crossfire v8 smokes wnen stated a puf of white smoke sometimes just a little sometimes a lot but runs great

it could be a lite blue colour that looks white,if so then the car is burning a little oil,the valve seals are probably dried out and allowing small amounts of oil to be drawn into the combustion chamber past the seal and valve guides when the car sits and when started up the oil gets burned in the combustion chamber.if its white smoke then it could be a small head gasket coolant leak.

Have excessive blue or white smoke from exhaust when truck is started after sitting for a few hours 2005 f250 6.0 ehgine

Hi,
is it a diesel or gas engine?
Usually excessive blue smoke on start up indicates oil is getting into the combustion chamber. It could be piston rings or valve seals.
Quick check, drive it within operating range and speed. Either use the rear view mirror or get someone to drive it and you follow in another vehicle. Accelerate, then take your foot of the accelerator. Blue smoke under acceleration indicates piston rings / pistons. Blue smoke on deceleration or the "over-run" indicates worn valve guides / seals.

White smoke can indicate coolant in the combustion chambers / leaking cyl head gskt, or incorrect fueling. If brake fluid gets into the combustion chamber it will generate a lot of white smoke from the exhaust. However, that would entail a leaking brake master cyl and a leaking brake booster.

Good luck.

There is oil on top of the pistons

Valve Seals are bad, you need the head rebuilt, new seals and valves. You could try a stop leak product to espand the seals if it has been sitting for awhile. I would not buy anything expensive, but it would be worth a shot, before you have to tear off the top of the engine. Mechanics refer to it as a "Head Job" Well old school mechs. Ask around. I know it is not the PC term, but it is definately Valve Seals oil is leaking past these seals and into the combustion chamber.

Oil blow back from out of the dip stick, what may be causing this and how to resolve the problem.

Time has come to retire this vehicle to the recycle plant and get yourself a nice new SMALL car thats fuel efficient.Most obvious cause is worn pistons and rings

Jiffy lupe said i need engine flush for my 2002 Jeep Liberty

No, this is not normal. if you have coolant or water leaking into the engine piston chambers, you will need a head gasket not an engine flush. if you open the oil cap to add oil to the engine and you see a lot of gunk under the cap, then its time for that flush. I would be concern about the more serious issue and that is that there is coolant or water leaking into the combustion chambers. this is a sign of a bad head gasket.

please rate and god bless..

I can tell about a couple of odors from oils that are quite indicative of the places where they oil is leaking into the exhaust though.

You've got a few internal places where oil can get into the engine and even some can get into the combustion chambers. They have distinctive odors and can really help diagnose the cause or reason for the oil consumption.

First let's start with the "sweet-smells".

This means that the oil have gone through the combustion process along with the engine's fuel (gasoline or diesels too!). It is about the same smell you get whiffing the exhaust on a 2-cycle engine with gas-oil premix.

Places where this CAN happen:

1) Cylinder walls ie; piston rings, worn or broken.
2) PCV system where the oil is sucked into the manifold under vacuum and is entrained into the combustion chamber in the normal air-flow to the engine for combustion.
3) Intake runner-to-head surface gasket(s) where the intake can actually **** oil from the cam tray area or the inner valley between the heads and the intake manifold.
4) Occasionally from changing spark plugs in "well" type plug chambers that let the plug get very close to the head through the head casting. Taking a plug out and letting the collected oil fall into the cylinder is usually a temporary situation, but can scare you when it happens.
5) Cracked head or blown head gasket: this usually has to happen where the head has a high pressure passageway for the oil to travel through the head to get to a cam tower on top of the head.
6) Now - here's something that's gonna get debated, fer sure! ONLY the intake valves can leak past their stem seals and allow oil to travel down the stem onto the combustion process. Remember that I am speaking or "sweet" oil smell here.


Now some of the "not sweet" or bitter oil smell:

1) Exhaust guides or stem seals on the EXHAUST valves ONLY can cause a very acrid smell of nasty, eye watering and cough-inducing stink.
2) CVCC or pre-combustion chambers can also cause this problem. The Honda CVCC engines were notorious for this! The auxiliary valve can leak oil into the pre-chamber and then it opens the valve and dumps the burning mess into the main cylinder head area and the results are a bad BAD stink and lots of white/blue smoke.
3) RARELY...very rarely the exhaust port AFTER the exhaust valve seat can become perforated and allow oil to get into the exhaust stream. It does NOT burn here - rather it just cooks-off with a very bad smell.

So-o-o-o

Acrid oil smell
- the oil has NOT gone through the combustion process in the cylinder head but is rather "cooked" into a stinky odor. It may or may not smoke too much too.

Sweet oil-burning smell - oil that has been burned as part of the combustion process in the combustion chamber on one or more or even all cylinders.
