    What you just asked is like calling the doctor and telling him "I'm bleeding...will I die?" You need to see where the leak is before you can determine what it will cost to repair! The burning smell is likely because some of the oil is going on the exhaust pipe and burning off.

It really depends on where the oil is leaking from. Most of the time, engine vibration and constant bumpy rides could loosen bolts and nuts here and there causing parts to brush against each other. In areas like the Gearbox and the engine itself, there is a thin material known as a Gasket that seats in between some these parts to prevent lubricants [i.e.oil] from leaking. If this gasket wears out, you have an oil leak. However friction is rarely the cause of oil leaks. When a gasket serves its time [after years of heating and cooling, contaction and expansion] it simply needs changing. So you could check to see if really you have worn out gaskets or loose joints.
As for the smell of burning oil, that is probably due to worn out engine rings. Around every Piston are a series of rings that prevent lubricating oil from going into the combustion chambers. when they are worn out, some oil becomes part of the combustion process reducing your cars overall power and causing smoke.
As for Cost, you wont spend much to have the oil leaks checked, as for the rings, you'll probably spend a little bit more. Where I live all that never goes past $170

When I first start the car a puff of blue smoke comes out the back after driveing for awhile a strange smell is in the car?

This sounds as if you have a rather High Mileage vehicle. (100,000+)
The puff of blue smoke is oil being burned in the cylinders. When the engine is cold, it will burn some oil, usually sucked in through the Valve Stem Guides.
Then after the motor warms up, and all the metal parts swell a little, it stops smoking as much. It is STILL smoking, but not enough for you to see it.

Obviously, you are losing engine oil, so check the oil level often, and refill/change as neccessary.

The 'strange smell' could be many different things. My best guess is that you have Oil Leaks on the engine, which is dripping on to the Exhaust Manifold, and getting burned there. Usually a Valve-Cover Gasket leak. When the car is all warmed up, open the hood, with the engine running, and see if there is any whitish smoke rising from the motor. if so, you have a leak on to the manifold. A very common problem, easily repaired. Or, you may have a leak in the heaters' Core, which will leak Anti-freeze into the cabin of the car. That would smell sort of sickly-sweet. This will be a much more expensive problem to repair.

Anyway, it sounds as if the car is in need of some maintenance.

Are ingition coils a known issue with the 2005 Avalon? Just reached 80,000 and have replace 2 already. Is expensive to do them individually, but repair cost at the dealership is way too hign for an all at...

They are fairly common especially the back three. Check your local NAPA. I have had no issue with there line of coils to date. They will run you about $90.

If the head has a slight leak which is getting into the motor, should I take out the motor or replace the head gasket?

If your head has a slight leak you're probably burning coolant and/or oil. With coolant burning the exhaust is a visible white color and smells 'sweet' too. Exhaust when oil is burning sometimes looks bluish. Smells like burning oil too.

Take out the motor? You mean fully replace the whole thing? No.

Why is the head gasket leaking? Did it overheat at some point? If so, then your problem is bigger than just a bad gasket. Milling (flattening) of the head is required and there might be other issues caused by the exhaust (oxygen sensors now might be fouled). Costs for milling and replacement might run around $1500, but this is just a guesstimate.

Good luck!

2005 avalon has ruptured oil cooling hose, with loss of all oil. Now has a rear main seal leak. Are the two related?

no they arent related, unless the engine crankshaft experienced extreme tempuratures from oil starvation. This mayhave caused the seal to expand and crack. Its possible but very rare!! Hopefully this helps!!

No oil in the crankcase, no leak from the plug

This is a very common problem and may be covered under warranty if you yell loud enough. There is an oil line that goes from the back of the engine and up toward the front. It fails and all the oil gets pumped out of the engine. Do not drive the car like this. It is a difficult job to repair because of its location.

I parkedmy car. smelled a smell looked under the hood and I saw smoke. I looked under my car and I see oil leaking out.

This answer will not solve your problem because your oil leak could be coming from any of a number of places. If you can Identify where the leak is and describe that area to me, perhaps I could further assist, otherwise, I would suggest you get a mechanic to check it out. Sorry.

Smells like burning oil, oil is running out under car with a small amount of smoke. There is no noise and no warning lights are on. Oil is under the hood on most of the stuff.

Most likely cause is a leak in the valve cover gasket. Under pressue, a good sized leak will spurt and burn off on the manifuld, causing the smell of burning oil you're getting. This also would cause the presence of oil throughout the engine compartment. Best of luck on your problem.
