Re: refitting head

[Steven Copcutt]

Craig   you can get the tensioner back in ( but not easy ) with a lot of patience . U need a small tire iron ( lever ) with a curl at one end and use this end with a torch ( so you can see what you are doing ) and lever the left side of the cam chain back where they seem closest . ( viewed from top) { this is with the head off }  before you attempt this you need to have a  piece of wood ( size and measurements is in the archives I think ) to put down between the chains when you get the tensioner in , good luck   Steve   NT ----- Original Message ----- From: Craig Guppy To: [EMAIL PROTECTED] Sent: Thursday, November 08, 2001 6:26 PM Subject: refitting head help! I just had my L18 head reconditioned, ported and polished and had a medium street performance crow cam fitted. the only two things I was told to do by the guy at the autopro shop before I took the head off was to set number 1 piston at TDC compression stroke, and make sure I didn't drop the timing chain. I did this. so now I'm at the stage of putting the head back on.   but now somebody else has told me that if the timing chain wasn't tight (which it isn't, it's hanging by a coat-hanger from the bonnet catch with about 1 inch of slack) I'd have to take the timing cover off to make sure it hadn't fallen off the bottom cog? (can you tell I've never done this before?!) anyway, I'm about to replace the cam sprocket and loop the timing chain up over it but there's 3 small holes at 90 degrees to each other (on the cam sprocket) that can each line up with the one circular extrusion on the end of the cam.   do I really have to take the timing cover off? so which hole fits onto this extrusion? the middle one?? what angle is the camshaft meant to be at? (the circular extrusion on the end of the cam is now at the 12 o'clock position) there's also three small indents at 90 degrees to each other, on the lobe that actuates the fuel pump (the lobe is held in place by a bolt that screws into the end of the cam), so do these have to line up with the three holes in the cam sprocket? should I use head bolt sealant when I screw the head bolts in?   I figure that since I know that no. 1 piston is at TDC compression, I should be able to figure the rest of these things out, but since I've never done it before I've got no idea!   any help would be greatly appreciated since I really don't want to munch a head that's just had almost $800 on it. thanks, Craig   p.s. is it worth while fitting an electronic fuel pump?
