![]() ![]() Insert the timing bit and see how well the timing wheel hole lines up with the drill bit. Find a drill bit that fits snug in the timing cover hole. The hole of this bolt aligns with the hole of the timing wheel when the intake camshaft tis fully retarded and aligned correctly. At the top center of the timing cover you will find a torx bolt. If the intake camshaft is aligned correctly then you can check the alignment of the intake camshaft timing wheel without removing the upper timing cover. Then mount the timing wheel and align it with the tool and tighten the timing wheel mounting nut. You will need to remove the upper timing cover, remove the camshaft timing wheel mounting nut and timing wheel, loosen the intake camshaft mounting bolt, line up the intake camshaft with the locking block and head (it’s best at this point to also install the exhaust camshaft locking block and link it to the intake camshaft locking block), then fully turn the vanos center shaft counter clockwise, then tighten the intake camshaft mounting bolt. If more than ~.5mm then the intake camshaft timing is off. Then while the intake camshaft is fully turned counter clockwise, place the intake camshaft locking block on the intake camshaft rear square and note how far off the head the locking block is lifted. Oil will spurt out of the vanos distribution piece. It’s very important to do this first and rotate the camshaft as far counter clockwise as it will go. Place a 27mm open wrench on the intake camshaft and rotate it fully counter clockwise. Remove the exhaust camshaft locking block. But the exhaust camshaft is not usually the problem. ![]() If so you will need to remove the upper timing cover, loosen the exhaust camshaft mounting bolt, align the exhaust camshaft with the locking block and head, and retighten the exhaust camshaft bolt. Look to see if the locking block is lifting off the head more than ~.5mm. Place the exhaust camshaft locking block on the exhaust camshaft rear. At this point disconnect the bank 2 intake and exhaust cam locking blocks.įirst check the exhaust camshaft timing. Then follow the procedure to align the crank harmonic cover and timing cover timing marks and inserting the crank locking pin. Instead turn the crank until the bank 2 camshaft rear square face with the camshaft designation (cyl 4-8) is facing up. Of course you won’t be able to do this because the bank 1 valve cover is not removed. When doing this the procedure will say to turn the crank until bank 1 first cylinder intake and exhaust cams are pointing to each other at a 45 degree angle. With the upper timing covers and all the components in front of them still installed, follow the procedure for setting the engine timing to TDC and locking the crank. To check and adjust the bank 2 timing perform the following.įollow the procedure to remove the engine air intake, fan/shroud, cabin filter housing, bank 2 valve cover. This code on this engine is caused by either a bank 2 aftermarket intake camshaft position sensor or bank 2 wrong timing. Author: rajaieq as Rajaie (moderator) : 1562 posts
