So i picked up this 92 Integra a few months ago that didnt even run when i got it. So i dropped the tank, replaced the fuel pump, and the ignitor and she fired right up. It drove ok, a little hot, for a few months and one night, started smoking as i pulled into a gas station. I thought it was headgasket, so i compression tested her when i got home. 155-155-158-165. So everything was good there.

I popped off the oil filler cap while she was idling and she was blowing white smoke like a geyser. Im assuming theres just excessive crankcase pressure. Shes also leaking around the oil pan gasket like a ****.

My question is this. Does this sound like a pcv issue or a busted ringland/rings issue ? Its also puffing from the exhaust under accelleration, same color as from engine bay. Grey-ish. Its burning oil like crazy too. I want it to be a PCV issue but i cant bring myself to believe a bad/clogged pcv valve would cause this much blowby. Thanks in advance for any and all help.

 

nah dead pcv wouldnt cause that much man

 

Bump for more opinions.

Is it plugged up?

 

Havent checked it yet, i will in a second. I just did a leakdown test.

Cyl 1 = 25%
Cyl 2 = 90%
Cyl 3 = 92%
Cyl 4 = 30%

What would cause compression numbers to show up ok but leakdown numbers to have such a variance?

 

Did you do them so that you rotate the engine so that each cylinder is on its tdc when you do conduct the test on that particular cylinder?

 

Of course.

Where was the air leaking out?

 

Throttle Body (intake tube disconnected.)

 

Anyone?

 

could be pcv. but from the way you described the amount of smoke. i would say you fried a ring

That would be from air leaking past the intake valves.

 

is there any noise from the valve train? check your valve adjustment and double check you leak down test. thats reallly low. also compare the plugs. also if you want to check the pcv shake it if you dont hear any noise its clogged. you could also blow both ways. you can usually use throttle body spray to clean out the pcv valve.

 

I would avoid cleaning just repl it. Mine was clogged I cleaned and oil consump went through the roof. 1/2 a quart in 50 mi. replaced the PCV and back to normal.
Also check to see if the hose is collapsing. or the port is plugged.

leakdown - valves bent, abused, or carbon build up.

 

....i say u say u should use lucas oil with some Zmax ...it'll solve all your problems ..... just f*ckin wid you man .... what were your findings?

 

A leaking exhaust valve. But it wasnt too bad. The PCV valve looks busted, but i dont know if i did that when i took it off. Lots of corrosion inside the block inbetween the sleeves. Its almost all back together. If i wasnt at school til 10 at night things could get done alot faster!
