I took the upper and lower off my car in the process of changing the lower intake and heads. I get it off, and start looking at the lifter valley. On the passenger side of the valley theres big chunks of im guessing carbon buildup. Its so bad that the pcv port is clogged. How can i get this out? Also the two fron ports and rear ports of the heads look like someone dumped a bucket of mud in them but the rest look fine......Whats the cause of this? Its been underpower/not running like i think it should. Im guessing this is part of the reason. Any and all info is greatly appreciated.

Is it hard and crusty. Just scrape it off the pcv port maybe poke through and remove it. As for the heads who cares as you stated above you are replacing them correct?

Yeah its hard and crusty, i started to dig in it a little bit but stopped, didnt want to have it fall in the bottom end. The heads are getting replaced, just curious as to what causes it.

Sounds like oil contamination and breakdown. What kind of oil do you run? You might need a little thinner viscosity.

dont really know what you can do. Try holding a shop vac and scraping it so it wont drop in.

Click to expand...

ever since ive had it, ive ran Castrol 5w30.......


I just got the drivers side head off, and im a little worried.... The number 6 piston wall has some scaring on it, Its not deep but its deep enough to feel with your fingers. Also looks like the piston has dings in it where the scaring is. The valves dont look like theyve been hit. What should i do? Is it ok to run like this for a while?

not replacing the PVC screen is what causes it. Most of the intakes I see have not had proper maintenance of the PCV system and it shows up as crud on the underside of the intake and in the lifter valley.

normally when engines have hard crusty crud do to really poor oil change maintenance its never a good idea to even really try and clean that stuff up because its gonna blow the engine. the only real way to get rid of it is a complete block teardown.

Regular PCV grommet, filter and valve replacement is one of the best things you can do to keep the inside of your engine as clean as possible. Interval will vary with the sealing condition of your rings. More often as they get tired. Pull the filter once a year - you'll know when it's time.
