• Q: How to remove the camshaft on 2008 Toyota Corolla?

  A: The first step to take the camshaft off the 1ZZ-FE engine requires disconnecting the negative terminal of the battery and removing the engine under cover RH. The first step involves removing the cylinder head cover No. 2 followed by the ignition coil assembly after which you should remove the cylinder head cover sub-assembly. The technician sets the No. 1 cylinder to Top Dead Center position during compression stroke. After marking the timing chain and camshaft timing gears, remove their accompanying two nuts and the chain tensioner following a rule of not spinning the crankshaft when the tensioner is absent. Loosen the camshaft timing gear set bolt by using a wrench on the camshaft with caution to prevent harming the valve lifter. The specified order requires the removal of 11 bolts while they are being uniformly loosened before extracting the 5 bearing caps together with the camshaft timing gear. The procedure for removing the camshaft includes uniformly loosening and removing the specified sequence of 8 bolts followed by removing the 4 bearing caps. The timing chain cover requires careful camshaft removal with the camshaft timing gear along with an immediate handholding of the timin chain and subsequent string tie to prevent content from entering the timing chain cover.
