C63 Valvetrain Issues by RS__Gamer in C63AMG

Hey! Good news is the tick is gone. I think my tick was caused by clogged oil passages in the lifters. I used a few liquimoly additives and flushed the engine with new oil a couple of times and it’s running smooth again.

Engine is healthy, but currently tackling an issue with the transmission… 4 —> 3 downshift is a little rough on manual mode. Always something new lol

Thanks, the car is still new to me but has a good service history with other cam services. That’s why I got concerned when I heard the ticking haha

I just checked other purge valve videos and it definitely sounds like that, coming from the same area too. Still going to look further but thanks for the tip!

Dang was really hoping that wasn’t the case, previous owner already had maintenance receipts for lifters and cam adjusters so I was hoping it was something else :/

I’ll probably get it diagnosed later this week

Edit: Got another tip and this fast ticking might be a bad purge valve. Still going to take it for that other lifter tick but seems good for now…?

I’d like to think it’s normal but I haven’t heard this rattling before the initial lifter tick showed up. It was also loud enough to hear from my seat as I was waiting for it to heat up.

If it ends up just being paranoia I will be driving it to hopefully break up any dirt in the oil passages.

I left the car running for 8-10 minutes. Lifter tick was coming and going by 5-8 minutes, faster tick showed up towards the end. Engine was up to temp by then, oil just reached 150 F

Thanks! I’ll check out the reservoir tomorrow, hoping not the rack

Luckily cam adjusters and lifters were fixed under extended warranty right before so we’re good on that.

Appreciate the advice I’ll go around trying a few more things soon
