Question about 2001 Saab 9-3

1 Answer

Two valves connected to my engine are broke. Blowing out smoke when my car is idling. One looks like a rod and the other something like rubber. Oil burns when I run it. And when I accelerate it makes a loud ticking sound.

Why is my car blowing white/blue smoke after standing in idle for extended period. no smoke present while driving.


Hello Barry, Two causes for your problem comes to mind. Smoke after initial start up and/ or extended idle could mean bad valve seals. Some time ago I had a car with a leaking vacuum modulator on the transmission. Intake vacuum was sucking the trans fluid into the intake manifold. Your car may or may not have a transmission modulator. White smoke usually means it is burning engine coolant.

Why is my 2000 kia sephia blowing blue smoke from the tailpipe. it has 86,000 miles. the check oil warning light is on even though the dipstick reads full.


The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. This is most frequently seen in older or high mileage cars with worn seals and gaskets. It only requires a very small amount of oil leaking into the cylinders to cause excessive blue exhaust smoke.

Blue exhaust smoke only at start-up can indicate worn piston seals or damaged or worn valve guides which may also cause a rattling noise. An external engine oil leak can drip onto hot engine and exhaust parts causing what appears to be blue exhaust smoke. Other possible causes of blue exhaust smoke include: piston wear, worn valve seals, a dirty or non-functioning PCV valve, worn piston rings, an intake manifold gasket leak, worn engine oil seals and possibly even head gasket failure.

Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. In addition, a reduction in power and oil loss can be indicators that the blue exhaust smoke is caused by an internal engine oil leak. Internal engine oil leaks can also allow fuel to mix with the oil in the crankcase which will degrade the oil and prevent it from adequately protecting the engine.

Operating a car with a severely dirty oil filter, air filter or improperly functioning PCV valve can also sometimes result in engine oil blow-by, oil loss and blue exhaust smoke. Periodically checking the engine oil level with the oil dip stick will indicate if there is excessive oil consumption. Higher viscosity engine oil can sometimes temporarily reduce the amount of blow-by; however, this is not generally recommended. Excessive blue exhaust smoke indicates a possible internal engine oil leak that should be inspected by an ASE certified mechanic.

Any advice on why my saab 93 smokes when hot and stationary


If it is smoking in the engine bay, check the PCV nipple. Stand in front of the car with bonnet open, and with the (rougly) trangular cover that is placed around the motor oil cap removed, look at the Valve cover - the black metallic engine part that says SAAB on it. On the left side of the farthest edge of the valve cover, there is a rubber piece that allows venting through a rubber hose. 46c4478f-2089-4631-9485-738202997749.jpg
If this is cracked or missing, you will see and smell smoke. This nipple/grommet needs to be replaced. What is called a PCV update should be performed - yo can DIY it through a web search. The parts all together cost about $70 or so.

Good luck!

1995 Oldsmobile 88 LSS 3.8 smokes at idle


Valve stem seals. Oil is thicker when cold (hence no smoke when cold) Vlave stem symptoms are when engine at idle (high vacume) oil is pulled through the guide seals, when you take off from lights get bit of smoke until oil is burnt. Ring symtoms is it would be blowing smoke all the time especially at higher rpm for extended time ie: driveing. Have you thought of trying a thicker oil? what oil grade do you currently run?

I havea daewoo nubira and we replaced the valve cover gasket yesterday , did an oik change and now the engine is smoking white smoke. Try to check to hoses, could not see a leak. Where is the cylinder...


Hello and welcome to FixYa!

The cylinder head is located on the center of the engine. Yes it can be a worn out head gasket or piston rings. If the piston rings are worn out the oil is burnt that's why it emits white smoke. You will need to replace the head gasket and piston rings.

Hope this helps and thank you for using FixYa! Have a good one!

1997 ford explorer V6. Engine was idling to warm up, went in house for 10 minutes. Came out engine smoking knocking like crazy. Shut off engine and opened hood, oil was sprayed all over engine oil...


this sounds like the engine oil cooler hose was leaking.

DO NOT run the engine again until you fill with oil.

start the engine and look for the hose that is leaking.

Overhaul of the top in of 2003 jeep 4.7. It had jumped time, broke a valve spring and bent a valve. After the overhaul oil pressure at idle drops to 0 after the engine warms up. No engine noise what so...


First thing you need to do is put a mechanical gauge in place of oil sender and read actual oil pressure. If mechanical gauge shows same condition, take a look at the connecting rod bearing serving the cylinder where the valve bent. If the piston hit the valve hard enough it may have created a flat spot on the bearing that is permitting oil to bypass the bearing, That won't knock right away because the bearing is still supporting the rod, unlike when the bearing bore has worn all the way around, and is loose. Bearings are made from soft metal, so that they can absorb a certain amount of dirt without damaging the crank. Being soft, they can easily be deformed.
If mechanical gauge shows no problems, just replace the original sending unit with a new one..

00 ford focus wagon a/c & engine smoke problem


Engine smoke problem-- Automatic, chk transmodulator. If oil in vacuum line, modulator is defective. Engine sucking up trans fluid. 10.00 fix . good indicator is smoking at cruising speed or deceleration.
Bad rings smoke under acceleration and bad valve guides smoke on deceleration. poor crankcase ventilation (pcv valve) will cause engine leaks and oil blowing out of dipstick. Good Luck

1992 gmc sierra turbo diesel starts and idles fine until warm up


It's time for a Italian tune up!

The blue smoke can be one of two thing.

oil drop from the valve stem (from engine head to cyclinders)
or
diesel soot collect inside the exhaust system.

===
I will take a 5-10 minutes high rpm (not redline) ran on the highway.
Pay close attention to the rear view mirror and look for black diesel soot.
=== I will use Diesel Cleen or similar product to condition the fuel. (keep moisture down)
Use the recommended amount of SEAFOAM oil additive to condition the valve stem seal/rubber parts.

I can not rule out excessive blown by.
Can you get a diesel compression tester?
When was the last valve adjustment?

Please post the actual odometer on the engine and I will follow up on it.
