I replaced the water pump and intake manifold gasket on my 96 blazer and it ran good, i drove it for about 30 miles then i decided to change the oil and now there is greyish whitish bluish smoke coming out of the ehaust pipe. ( i cant really tell if its oil or coolant or fuel?) Also it doesnt smoke right at start up, after about 30 seconds of running it starts smoking. Im worried it is head gasket, but i dont think it is.. (going to check if its losing coolant) Seems like it is burning Oil. The PCV valve is good i just checked it and it has the correct amount of oil. Im currently checking to see if its loosing any coolant or oil. could it be burning to much fuel or something? injector problem? im just confused as to why this happened after i changed the oil. Also there is a Cylindar 5 misfire problem, it has been on there for a while though, way before it started smoking. Could it be from old spark plugs? any help would be awesome, im tired of putting money and time into this car. I also read that maybe its transmission fluid sucked into the intake? how would i test something like this?
also currently it has just water and no antifreeze in it, not sure if this has anything to do with it. It is not over heating.Smoke out of the exhaust after i changed the oil.?
Chances are you used too thin of oil. You may want to use a 20-50 rather than 5-30 or 10-30. As for trans fluid, unplug the vacuum hose at the transmission and it should be dry. No fluid in it at all. If the modulator is leaking it's easy to replace. There will be stripes painted on the base for identification. I'd check the misfire too. Is it the plug, injector, the wire, or compression? All except the compression are usually easy fixes.Smoke out of the exhaust after i changed the oil.?
if the transmission has a vacuum modulator then pull the hose off and check it. if it has transmission fluid coming out the hose then your motor is sucking the fluid up into your intake and that,s where you see the smoke. also make sure the oil is,nt laying under the valve pan. if it is then the drain holes are clogged up and running down on the valves.
