EJ205 4th cylinder - Knocking Prevention?
 

Hi guys,

Please let me ask for your opinions...

My EJ205 engine sounds great with no knocking or something like that. I am afraid after hearing some horror stories about the 4th cylinder and its knocking.
What can I do now to prevent the 4th cyl knocking in the future?

As for now:
1. Engine is working under normal and average loading conditions, around 2000-3000 RPMs. Just family driving in the city with rare active accelerations and higher RPMs, with no drifting and extreme driving.
2. Mobil Synthetic oil (Bought a number of jugs on sale) change every 3-4k km with the oil filter for sure.
3. Engine warms up every time after the cold start, even in the summer (warms up for a few mins).

Anything else?
Should I install an aftermarket aluminum (larger) radiator? I am not sure if its a must and if its needed for my careful driving.
Insulate the exhaust piping under the hood?

Please advise.
Thank you.

Stop reading the internet.

If it's not knocking now, and you maintain it, run it on good fuel and dont drive it like a díck you'll be grand

Well said. Thanks
