Hi, I'm dismantling an R16 and have run into a problem removing the camshaft.
The cam retainer came off easily and the camshaft moves about 2 mm front to rear but the front most lobe (number 1 exhaust, I think) bumps against the front cam bearing.
I always thought the lobes were smaller than the bearing. This seems to not be the case.
My question is simply how do I remove the camshaft? Do I need to pull the front bearing first?
Thanks!
If you don’t invert the block you need to hold every lifter up to get the cam out.

I have never tried to hold all the lifters up, that would take a lot of magnets to pull it off, I just turn the block over.
The block is inverted, I think I've got the lifters out of the way but I will double check those.
Really frustrating as the cam rotates fairly freely and does have that forward/backward movement but it bumps into a hard stop and I don't really see what that is.
I'll get back to it later and report back what I did to resolve it.
thanks!
The only things that I recall that would stop the cam from coming out are the retainer, the lifters, the fuel pump and the distributor gear - you have to pull the distributor base to get it out. The oil pump may be in the way as well. It's been a while since I have been inside a block.
Got to it this morning. Unfortunately I don't have a definitive answer as I turned it over upside down, gave the cam a couple of taps and it popped loose.
I suspect that it was hung up on a lifter because when I left it, I turned it right side up and spun the cam several turns. I think this pushed the lifter out of the way for me this morning.
