Question about 1994 Geo Metro
Occasionaly smokes a lot and blows oil on engine. seems to be to much pressure in valve cover
Posted by Anonymous on
Smokes where? and what color, ?
ill guess tail. pipe end? if not, nows the time to say where.
black is fuel (tail)
white is oil or steam, oil smoke lingers and smells like burning oil
steam goes a way fast like moms tea pot. and sames nasty sweet in fact smells like AF, antifreeze (got that, if not you cracked the block)
suzuki has huge oil returns, no need for this unless engine is packed in sludge. never changing oil
the PCV valve is clogged, or far worse.
a bad engine can overwhelm any PCV. easy.
the engine is leaking
that can be PCV packed or bad seals and gaskets or both.
why not get the engines serviced?
do the 60,000 mile list of service points and win.
if the piston rings are bad, there will be huge blow by
and no PCV can handle that..... so check PCV first.
then if that dont fix it check for excessive ring blow by,
do a cylinder leakdown test. (by the book)\

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.
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).

The only way I can think of that raw gasoline could get into the oil is at the thottle body. So, the fuel injector or fuel line in the throttle body would be the first place to look if you're sure that it's gas in the oil and not another fluid.

You might also check the single injector, had a friend's that the fuel pressure regulator had been messed with and was over-pressurizing the injector, that weakened the injector allowing it to flood at idle and also when cut off (the injector was leaking)
