Blowing blue smoke

I recently got an oil change. Truck was running fine but over due for the oil, after it had been changed I noticed that as I would take off the exhaust didnt seem to flow as smooth , you can hear it putter or bog, and it seemed the psi on the boost was going higher than before the change (10-20 psi after) and also found some oil leaking on the cross member not sure were it is coming from.Had no leaks proir to oil change.....

SOURCE: 1998 mustang gt coolant leak

I just had the same problem. Ford design the intake manifold with plastic water crossover which cracks. The coolant will leak onto the top of the block and and then down the back of the engine. This intake design is a known defect and was ocvered under by Ford for 7 years past the date of mfg. The crack either is in the crossover or the thermostat housing. I happed on this when I found the same leak and traced it back to the thermostat housing. I changed the thermostat, but it leaked worse. You can pickup a aftermarket for $200 and it's about 4-6 hr job to replace.

SOURCE: 1984 ford f150 running erratic.

Check and adjust your choke accordingly, also since you have given it a tune up you should adjust your timing if it needs adjustment. Also check for any vacuum leaks. As for the exhaust leak I would look along the exhaust manifold and then along the exhaust pipe under the cab, check where the exhaust manifold and the exhaust pipe connect as there should be a donut or flange in there and it could be deteriorating. Good luck and remember to rate all the solutions you get, thanx.

Third season, fresh gas, oil changed, starts fine, runs fine, throws fine, but every once in a while belches blue smoke. Should I be concerned?

Would this be a mower by any chance rather than a Car or Truck?

Mowers do that, because they are high revving and periodically oil shoots past the oil ring if it is a 4 stroke, or on a two stroke oil builds up in the bottom of the crankcase and gets thrown up into the combustion chamber every now and then. Try not to rev it too hard.

Blue smoke is burning oil.

Why would oil and water leak out of my Lincoln navigator 5.4l engine

Worse case this could be due to a blown head gasket - however let not jump to conclusions. Where is the oil coming from and did you have it changed recently? Water is common from the A/C condenser and or over fill of the wiper fluid or possibly rain / bad oil change place that "rinses the engine" with water to get excess oil off. If you did have your oil changed / car serviced, take it back and have them check it. Maybe it's a loose oil filter or loose oil drain plug / bad washer on the drain plug. If you haven't have the oil changed recently, did you hit anything or did the car over heat recently? To see if you blew a gasket, check your overflow tank coming off the radiator. Pop the cap and look inside to see if you see oil (not dirty water / coolant). Also check if the car is blowing blueish smoke or excessive white smoke when you drive / rev the motor. If not, hopefully your fine. Post more details and you'll get a better answer. Good luck!

Truck shakes when started, smokes blue, lots of blow by

Blue smoke on starting is a sign of oil in the engine cylinders. .
Excessive fuel would be black smoke on starting. I am concerned that it happens when starting. This is an indication of a valve issue. Bent, broken, bad spring, wallowed guides. This repair is not going to be cheap. Only way to know for sure is either a compression test or leak down test.

I have a 5L-E toyota hilux that runs fine at idle yhen when you rev it to about 2000 rpm it starts to blow alot of white smoke. I have cut injectors out while the smoke is blowing with no noticable...

i believe the engine is running too lean as if it was running too rich it would blow black smoke If it was blue smoke it is oil related eg valve stem seals,valve guides and or piston rings all of these things will create blue smoke if one of the above is worn out

2008 6.4 f350. blowing tons of blue smoke for the last 12 months

Blue smoke means burning oil. Black smoke means running too rich (too much fuel in the air/fuel mix). If it is blue smoke:
If it blows blue smoke only shortly after starting, it means oil is leaking into the cylinders from above, through the valves. This us typical of older engines, and can be repaired without removing the engine from the truck (although it is still expensive). A 2008 should not have this kind of problem.
If it blows blue smoke all the time, it is bad piston rings or scored cylinder walls. Oil is leaking from below up into the cylinders. This is bad news - any solution will require removing the engine from the truck and complete disassembly (i.e. a rebuild). No engine oil treatment will make it go away, regardless of what the label says.
It is very, very rare in modern engines for a well maintained vehicle with less than 100K miles to need a rebuild. Damage such as this usually comes from not changing oil AND the oil filter often enough. 3-4000 miles for conventional oil or 6-8000 miles for synthetics. If using synthetic, be sure to get a high quality filter designed to be effective for the synthetic oil change interval.

Engines idle goes up and down after warming up and blows blue smoke

If the engine idles for a while then blows blue smoke this is an indication of oil passing the valve stem seals and being burnt in the combustion process. ( When you are at lights and they change and you accelerate away leacing a cloud of blue smoke this is worn valve guides and failed valve stem seals) As for the idle it could be the oxygen sensor is coated with oil and soot and is malfunctioning henace the cpu cannot regulate the fuel setting correctly. Have the valve seals replaced and clean the Oxygen sensor and check for other fault codes

1999 pontiac firebird blowing gray smoke drives fine short distance but will not restart after parked was low on oil and had just had recent oil change and no noticeable oil puddles....master air flow...

Sounds to me like a cracked head and/or a blown head gasket. Is the car low on water in the radiator and if you live in an area that is cold do you have enough antifreeze in the car.

Engine oil

It is not unusual for an older truck to be burning a little oil. It is burning very little so you will not smell burnt oil or see blue smoke in the exhaust. But the oil burn does add up and you may notice a drop on the oil dipstick after a few weeks. On a 9 year old truck under normal working conditions will burn a little oil. If you are having to add 1 liter between oil changes, that is ok, just shows normal engine ware. 2 Liters is acceptable between oil changes if the truck does a lot of heavy pulling or work. 3 or more liters indecates a problem, but at that rate, you should be able to smell oil and see blue smoke.
