    I just noticed oil running down the block from my knock sensor, is it shot?

    Kind of strange, any help would be great.

    Well I'm not Buck or Luv2rallye :) but if the goo is leaking out of the knock sensor then it's time to replace it. A quick search will confirm that is the sign of impending knock sensor death

    Haha, thanks steve. Don't take my previous thread personally, I appreciate the help. Although I was waiting for them because had had spoken with them about it previously.

    Thanks,

    I don't, they are both well respected, knowledgeable guys. Just pulling your chain.

    My knock sensor is just starting to do this too. It hasn't started dripping but I can tell I'll have to replace it sometime soon.

    Mine is leaking pretty bad actually. Enough to get on the axle and all the way down the control arm. Unless of course it's yet another leak that I don't see.

    Let's just say I blew some seals, which soaked my tbelt, and I just got finished replacing the whole side. Start it up, and of course, there is still another oil leak that I can't find, and I don't want to run the risk of soaking the tbelt again. So it's going to be sitting until I fix the leaks.

    I see oil dripping off of the knock sensor, so I know that needs to be replaced. I replaced the cam seals during the tbelt job, but somehow there is oil getting onto the outside of the cam sprockets.. doesn't make sense at all. The only possible thing I can think of is the valve cover gasket, that's got to be it.

    And last, there is a leak on the front right side of the block, I have no clue where it's coming from, and I'm worried that it could possibly be the headgasket. Anybody know if it's even possible to leak oil from the headgasket?

    Again, thanks for all the help.

    It's possible to leak oil between the head and the block since oil passages pass between the two but I'd expect you would have other things leaking too.

    If you have oil leaking down the knock sensor and not a thick goo it might be from your oil leaks and not the sensor breaking down.
