No! Reliablity would be it breaking, it does no such thing. Let's say you have a small oil leak on your car, even if your rear main seal is leaking, it doesn't mean the engine is unreliable. It means you have a leak and a small oil pressure loss. Is this terminal on a car? NO. Many cars drive around even on track with small oil leaks, is it ideal? No. Is it terminal? No. Will it lead to catastrophic failure as long as oil level and pressure is adequate? NO! Can you improve it, and make it a non issue? Yes absolutely? Luckily time is on our side, and shouldn't take long to get this sorted.
Reliability is an issue and in the quest for bulletproof reliability, you must leave no stone unturned. Particularly since the power unit components are so interdependent. There are so many systems on ANY ICE, that depend on hydraulic oil pressure. The turbo for one, the crankshaft, the pistons, and rods. The camshafts, the other parts in the cylinder head and lubricating cam timing mechanisms.
