ok i got my motor from some dudes in a farm that said its been sitting for like a year. when i got there it was laying on the side of the starter. so i put it in and it smokes real bad. i checked compresion test thinking it was bad rings but all cyclenders are good, no oil puddles under car. cant find the oil leak but its smoking through the left breather hole on the valve cover. and its buring alot cuz as im driving the car it fills with smoke at some points and other times u cant even smell it. im lost. plz help

 

have you check your valve guide seals? some place's put cheap one on when they rebuild there heads.
if the intake one are bad ,it will smoke some when running. if exhaust one are bad ,then it will smoke when you first start it up.

 

startup is good but running is bad especialy if the pedal kisses the floor.

 

also check the intake gasket too.

 

wut do i check for?? it was the blue gasket. could it be the head gasket and still hold good compression?

 

When you say compression was good, what were your readings for each cylinder?

 

some times the intake do not seal all the way in the lifter valley side. which will cause vacuum leak. which will suck any oil into that cylinder.

you say you did compression check.
did you do one dry and one wet? if not ,your not going to see if your any ring are sucking oil.
do normal compression test dry to get all the readings. then go back and in each cylinder put about 3 to 5 pumps of 20w50 oil from a oil pump gun. if your compression increase in that cylinder, then your ring fine but if you have one that don't increase, then your oil ring in that cylinder not working and leave the cylinder wall wet.

 

i did the 1 where u put it in the spark plug hole and crank it. i dont remeber the numbers but ill do it again in a lil bit and post #s for u. and i also just found there is a rattling noise coming from the pulley area when its around 2500. brand new water pump and alt. could it be related?
