Be sure to set engine to 90 degreest past #1 Top Dead Center prior to rotating your camshafts. Once your camshafts are in the correct position pin them in place to prevent movement, turn crank counter clockwise to number one TDC. Everything is now in the correct position to install the timing chain. After installing everything double check all marks and positions then unpin the timing sprockets and release the tensioner retainer. Verify the tensioner plunger extends. Be sure to lubricate everything prior to closing up.\r

While your timing cover is off you might consider checking the oil pump which is located in the timing cover. Be sure the oil seals on each side of the crank are still in place prior to installing the timing cover.\r

When installing the timing cover clean all mating surfaces well and use a suitable RTV sealant or equivalent.\r

Pivoting chain guide 26nm (10mm bolt x 1) be sure under bolt head is clean\r
Tensioner 14nm (10mm bolt x 2)
