Air filter is saturated w/oil

[meatloaf]

My 83 FJ60 2F was running rough...I pulled the air filter and it is saturated with oil, what's up with this? I changed it and put a little over 1000 miles while on vacation a couple of weeks ago. Also, the engine smokes when shifting gears. MOst of the oil on the filter seems to be coming from the hose that splits from the pcv valve (~6 months old) and connects to the bottom of the the air filter housing. also, the engine seems to 'knock' more than usual.

Another question: I am considering swapping the engine/tranny with a Chevy, what kind of $$$money (not including eng/trans) am I looking at? How difficult is it to do? I'm no mechanic, but I swapped a couple of Toyota engines,clutches, etc. on my truck.

Thanks in advance for all the help.

My S-10 had these exact symptoms (almost 10 yrs ago). Turned out to be a cracked block allowing coolent to mix with the oil...too much pressure...spits out the controlled ventilation valve. Check the color of your oil. Could also be a bad head gasket. Or blow-by. HTH.

what is blow-by???

 

[TwoThirtyDirty]

Blow-by refers to the escape of compression and exhaust gasses past the rings thus increasing pressure in the crankcase. In moderation, excess crankcase pressure is vented via the Positive Controlled Ventilation valve into the air cleaner where it mixes with incoming air and is burned. Too much pressure (ie. blow-by) and the oily vapor leaves deposits in your air cleaner....could be a little...could be alot depending on the severity of the problem. Get a compression test done...should shed some light on the situation. If the oil in your air cleaner is milky colored then the increased case pressure is due to coolent/water in your oil (cracked block, bad head gasket).

Thanks guys,

the oil in the filter is not milky...can someone explain the correct procedure for checking compression. I bought a comp. gauge and I would like to do it myself. The extent of my knowledge is that you pull all the spark-plugs, insert the gauge and crank the engine.

Again, thanks for all your help.

Well, the No. 4 cylinder seems to be dead...can't get even 20 psi, even with 10 crankovers.

time for a rebuild

You might check the valve adjustment before declaring the engine dead. If the blowby is excessive, you can sometimes feel pressure at the oil filler hole. With the engine idling, if it will idle, put your hand over the open oil fill hole. A tight engine won't have pressure there.

I'll check it tonight when I get home. Last week with the filler cap off, I could see plently of smoke coming out (looked like a steam pot).

Oh, well in that case, "time for a rebuild" or you could try the 2 case test. It involves 2 cases.....

A case of beer for you, and a case of MOTOR MEDIC for you engine.

Seriously, You might as well try one or more of the additives that are supposed to free up stuck rings - you've got nothing to loose.
