Cam lobe scuff/wear - How urgent to replace?
«

So yesterday I was performing a valve lash adjustment. That's when, I noticed this...
These 2 show the wear all of the intake lobes seem to have. Doesn't look too bad, but I'm not qualified to say.
These 3 are of the far left and far right cylinders' exhaust lobes. These look like they need replacement, but again, I'm qualified to say...
***
How bad is this?
Will it get worse over time?
Will this need immediate repair, or can it wait a while?
Other thoughts, opinions?
I believe this is related to a low oil pressure issue I had a few years back due to a clogged oil pickup. Enough to cause the VTC not to activate, sending the car into limp mode. I had the dealership clean out the oil pump pickup and VTC strainers for free because this occurred within days of an oil change they did *AND* their man only put in 2 quarts of oil. It's worked fine ever since, no oil pressure issues. I've also started doing my oil change and switched to M1 full synthetic and switched over to a ~4000-4500 mile interval.

I'd definitely change that exhaust cam. The intake doesn't look bad at all but considering there was some starvation earlier in this engine's life, it'd be safer to replace both cams.

Intake cam looks okay, but you probably want to make sure there isn't any scoring. That exhaust cam is pretty bad though. You definitely want to replace it.

I agree with both of them as being my professional mechanic opinion. Deff check the intake for any imperfections scuffing on the lobes

I just did the valve lash adjustment last weekend as well, here are my results.

The intake valve lash was pretty decent, but the exhaust was way too tight.
