If you wanna keep the engine from turning into a rust‑ball, the first line of defense is a good oil change schedule and a top‑grade oil that matches the manufacturer’s specs. I always swear by a decent oil cooler on high‑output builds – it keeps the temps low and gives the oil a longer life. Keep the coolant fresh, replace it every 2–3 years, and make sure the radiator is clean. A small aftermarket heat‑shield on the exhaust headers helps keep the engine bay cool, and I use a high‑performance oil additive that coats the pistons and valves to reduce friction. Finally, never skip the little things – tighten the valve springs, keep the timing chain tight, and check the spark plugs. A clean, properly lubricated engine is the best spell against heat and rust.
