Gday, I’m just looking for some help with doing cams and valve springs, I’ve bought the cams already because they came with a cpr6 and a bunch of other things for extremely cheap.
Im not looking to be told that I shouldn’t do it n what not, and I’m open to any ideas anyone has.
So to start off with, I’ve found that there is pretty much nothing online to do with replacing camshafts on alloytecs and same with valve springs, there’s a few forums hanging around but nothing really in depth. I’ve taken a look at the service manual and it seems like that’s my best bet. I’m trying to replace the cams without removing the timing cover, and it seems like it’s possible with the timing retainer tool. The main question is how do i use this tool? From the looks of it I place it in between the two tensioners and tighten it, not too sure though.
And the next thing is valve springs, cause I’m gonna be keeping the heads on it’s gonna be a lot harder because of the valves falling down into the block. I’ve seen most people used compressed air, I’ve also seen people put rope down into the cylinders. I’m thinking compressed air is the go, but won’t I have to rotate the engine to close the valves that I’m putting the compressed air into?
And lastly the tool to compress the springs, the manual says I should use this (EN 46110). But it costs around $500!! Is there any alternative, I saw a forum of a guy who bought a tool and he had to modify it heaps and took him ages to do. If anyone has any links to forums or videos regarding cams and valve springs that would help a lot. I’ve seen there’s a fair few timing chain videos but I’m trying to do it with the timing cover still on.
If anyone could help that would be appreciated, I’m trying my best to tackle this myself.
Cheers.
