i posted this about 10 days ago at clubsi, but havent had much success... the link is http://forums.clubsi.com/showflat.ph...b=5&o=&fpart=1

the long and short of it is this: i was installing gsr cams in my si motor. when i went to replace the cams and bolts and whatnot, the cams would not seat properly. the motor is at tdc, and the cam sprockets were pointing straight up when i removed the si pieces. now the cams will only sit with the up arrows pointing slightly inwards. ive also noticed that both the cams are not seating properly because they are in contact with the medium-sized (secondary?) rocker arm on the number 3 cylinder on the intake side and number 2 cylinder on the exhaust side.

anyone know what the problem is? i included some images, hopefully they make things a little clearer... thanks in advance.

The VTEC rocker arm is the only one that is supposed to have any give without having to exert a lot of effort. You should be able to push that middle (VTEC) of the three rocker arms down with your finger.

It's ok that the cams don't align perfectly just yet....that all happens after you've got the cam caps and plates all torqued down.

Use the proper bolt down and torque down sequence.

Lube your cam journals and caps more.

 

even after the caps and plates are torqued down the cams aren't properly aligned... should i be able to turn them by hand at that point?

also, it looks like the cams will push down on the rocker arms mentioned above if i force them into the "up" position. is that normal? are those two rocker arms supposed to be pressed in?

i will try lubricating them further tomorrow. thanks.

 

mark on the timing belt where UP is before oyu take the cams out

when you put the gears back in, slip them where they should be according to the marks

then bolt down the distributor side slightly (so it catches but do NOT torque) then go about with the rest of the caps

that's how i did it. i did have to force a bit. but if everything was at TDC to start and you did not move the crank pulley, then nothing should happen bad.

You will be able to turn it by hand, but there are certain areas in the circle of rotation where it will require a lot more effort...especially on the first time turning the cam over immediately after installing them. Those "certain areas" are where the cam lobes are pushing down on the non-VTEC lobes.

Use a 14mm box wrench and get it approximately to TDC #1. Then tap the wrench over with your hand until you get it (the line mark facing towards the middle) perfectly aligned with the mark on the rear timing belt cover.
