Sucking Oil

[dkdeford]

1985 2.8L 2-bbl using a ton of oil; getting a lot of it accumulated in the air cleaner housing, coming in through the breather hose off the valve cover. What can cause this? Worn valve guides/seals?
Thanks for any advice.

If it is burning oil yes replace the valve guide seals you can do it without pulling the heads. How old is the PCV valve? Just change it with oil changes they are cheap and plug up fairly often in these older motors. Give the engine a good decarb that may reduce the blowby past the rings. Get a can of seafoam and bring the engine up to temp. St a fast idle pour seafoam in the carb until smoke starts coming out of the exhaust and quickly shut it down for 1/2 hr. Then start it and run it around 3500 rpms until the smoke clears. If there is alot of carbon on the pistons it will put up quite a cloud make sure the windows and doors are shut in your house and the wind is blowing toward the nasty neighbor

I used one of these and a compression tester fitting. Pull all of the plugs and find tdc on #1 on the compression stroke. Put around 30psi air pressure in the cylinder to hold the valves up. Then just follow the firing order by putting a long skinny screwdriver in the next spark plug hole and turn the crank clockwise until that piston is all the way up. After the first couple it went really quick. Just pinch your fingers on top of the keepers so they dont fly out and tap lightly on the tool to pop the spring retainer down off of the keepers.
