Timing Chain Tensioner Seaping 2006 toyota corolla?

Mike N

Went to get a oil change for a 2006 Toyota corolla and the mechanic says that my Timing Chain Tensioner is Seaping.































Firstly, What is this problem?















Any idea if this is a major problem?















What would happen if i just ride it out and not fix it?































Thank you very much

SUPER easy to fix.































step one - let car cool down.















2 - you'll find the tensioner held down by two 10mm bolts at teh back side of the engine, near the timing cover. The tensioner can be accessed from the top, so don't worry about putting it on a hoist.















3 - undo the two bolts holding the tensioner in place.















4 - remove the tensioner, clean up all oil on it, and on the engine block where it was removed from.















5 - in a vice, carefully compress the tensioner to the point at which it won't move back anymore (it's spring loaded)















7 - on the side of the shaft, you'll find a little 'lock' to hold it in place as you service it, with the tensioner compressed in the vice, clip this on, and Then release the vice.















8 - Now where the rubber o-ring seals on the tensioner, apply a good bead of black or orange silicone to seal it up, and reinstall the tensioner.















9 - Tighten down the two bolts that held it in.















10 - with a socket and ratchet on the alternator pulley give the engine a little spin-over back and forth until you hear a 'click' as the little arm has released the timing chain plunger.















































These things always leak,, its not worth replacing the part... it IS worth re sealing it... they last for a LONG, LONG time that way.































Git er done!
