Blow By Issues


Recommended Posts

Ok I am running out of ideas with my manche. I cleaned out the valve cover and cleaned out the baffles. I have replaced all the CCV tubing and no change in the oil in the airbox. The compression is great and doesn't burn a drop of oil just leaks it out.

 

Is there anything else I should be looking for? I mean are those baffles when I took them out of the valve cover they were both up maybe a quarter of and inch. Maybe not that much but I mean are they suppose to be up like that or are they suppose to sit totally closed. The valvecover was taken off sometime before I owned this truck.

 

What else should I be checking for that was cause this?

 

Thanks.

I had blowby really bad and a simple cleaning of the tube from the valve cover to the airbox to get the gunky oil solved about 95% of the problem. I took it off the engine and ran wire coat hanger down it a few times and pushed a whole bunch of sludge out of it.
