As Roddin1 mentioned it could be a coolant leak, or it could be and hopefully is something less serious. Any chance you live somewhere cold and you don't let your car warm up before driving off? Because if not condensation will build up and cause that yellow/white goo.

You have antifreeze getting in somewhere as it's the only thing that will make oil foam up and get a gooy greyish white color....you might check to see where it shows up strongest and check that part of the engine closely for a leak...

First stepwould typically be to replace the PCV valve. It's located behind the valve cover at the bottom of the rubber tube that connects to the back of the valve cover and branches off to the air filter housing.

Alternate possibility:

If the head gasket has been replaced, it's likely one of the oil returns is blocked (replacement head gaskets, for whatever reason, don't usually align with the head correctly). The solution is to open the secondary oil return. I used a one foot piece of 4 gauge bare copper wire (more of a 1/4" copper rod). Remove the valve cover. Taper the end of the copper wire to a blunt point and drive it about 6 inches down the oil return on the backside of the head near the rear of the head (directly behind where the oil filler cap was).

Missfire after filling oil


if you poured the oil in to fast oil might have passed threw the pcv system and flooded out a cylinder with oil or its a engine with the spark plugs in the center of the valve cover and the seals in the center leak oil and when the oil was added it drained oil into the spark plug wells and shorted out the spark plug

MY SUZUKI GET TOO MUCH WHITE SMOKE,BUT I HAVE PUT ENGIN FLUSH, CHANGE THE OIL AND THE OIL FILTER,ADD ANTISMOKE TO FUEL BUT NO CHANGES PLEASE!!!


There has been an issue of Suzuki engines smoking due to the PCV. valve or the baffles under the valve cover. One method of curing this is to place an oil separator between the vacuum line from the intake and the PCV. This will make for the need to keep an eye on it as it will fill up with oil eventually thus negating the purpose of placing it there in the first place. I think the big fix would be to remove the valve cover and check the oil baffles and filter therein. The problem is that oil builds up at the location of the PCV and is getting sucked into the intake via the vacuum hose to the intake. The quick fix? unplug the PCV and plug up the vacuum hose to the intake. This will get you by until you can get it to a mechanic. Anyway, That what I know. hope it helps

Oil filter is tight and seated properly, drain plug is secure and no leakage- have had some oil smell while driving the past week or so- pulled into home and oil smoke pouring out of engine compartment and...


Check Front main seal, rear main seal, or one of the EGR hoses. Check oil fill cap. Also check filter if seal was crushed too hard it may be spraying oil out of it. Where is the largest amount of oil? May tell where its starting from.

Engine smokes blue white right side only


I'm going to guess it's a blocked oil return in the head under the valve cover. If it fills up the rocker cover, the valve seals can't handle that much oil and it gets into the combustion system. Try looking through an opening, oil cap, PCV valve opening to see if a lot of oil is pooling up.

Otherwise, it could be the PCV valve if causing pressure in the rocker cover. Or valve stem seals if it's worse on acceleration after coasting down. Good luck

the pcv valve is behind the alternator between the alternator and oil filter. when you remove the oil filter you can see the pcv in the intake manifold. best way to get to it is through the pass side fender under the rubber mud flap thats between the wheel and engine.

Smokine exhaust.


Take the pcv valve out of the hose and check it...Shake it,if it rattles it probably is good..But a new one would not hurt.Make sure any other ventilation hoses are routed right.If it only smokes while the hose is connected,then it is pulling oil from the valve cover into the intake and burning in the combustion chambers...Check your oil level as well...Good Luck!!!
