Engine Disassembly Question

[Nintain]

Like many other owners, my 2015 scion frs valve spring broke and punched a hole into the valve head cover. I'm currently disassembling it to swap to a brand new factory oem short block but I've run into an issue. In the car manual for disassembling the engine, it states for when removing the timing chain, tensioner and guides that you have to turn the crank to where the two cam arrows meet or else it might cause damage to the valves. Well my issue is that my crank won't turn very well because I'm assuming there is metal aluminum bits stuck in the cylinder bore to where it won't turn. I don't plan on keeping the the old short block if the solution requires me to deeply damage the bore. What would anyone recommend, would removing the timing without turning the cams to the correct position damage anything? I appreciate any advice

Note: I do plan on taking apart the valve head to inspect and replace springs, guides and retainers

If your fully disassembling the heads don't worry about it.
It wont be the same anyway after taking the head apart.

Actually a valve spring failure is very, very, very rare even on the 13s with the alleged "issue". On a 15 it is almost unheard of!
As x808 said if you are completely striping the engine for a new short block it really doesn't matter.

Thanks for the input, yeah I'm surprised myself. I bought the car used, drove for 6 months and then my engine seized. There was definitely plenty enough oil before it blew onto the road and when I took my passenger side cover off where a hole was made the spring was broken. Not sure if it was the direct cause, maybe a rocker fell out and started knocking things because the cams are definitely damaged

It for sure just kicked the rocker.
