Cylinder head removal - timing marks and chain removal
Posted: Thu May 02, 2019 3:17 pm
first time post and looking for some help while I strip my engine down to solve the low compression issue.
any help would be greatly appreciated!
- 1st question would be which cam marks i should be using to find TDC so that i can safely remove the cyl head, when i look at the end of the cams there are 2 notches about 5 mm in width but on the opposite side there a 2 corresponding stamped lines? i can get the stamped lines to line up at 3 and 9 o'clock but the 5mm notches do not look like they line up exactly!? I am guessing its one of the cams has jumped a tooth and is out of sync or its a matter of perspective and im just tripping out :)
- 2nd is what is the best way to remove the cam timing chain as the manual has one step (3.10) about removing the cam journal holders then the next step (3.11) there is no chain in the photo and they are whipping the head off. is it a case of removing the tensioner to provide enough slack to slip the cams out? I am trying to avoid removing the cams and take the head off as one unit so is there a safe way to split the chain without destroying its integrity?
any help would be greatly appreciated!
