Hey been ofline for a while, i carried on using my car daily, about 2 weeks ago my engine managment light came on, same fault code and few more, when erased you can here the engine tone change. Im thinking my timing chain may of stretched over time.so i have ordered both chains,new guides tensioners and rear main oil seal etc, going to tackle this on a bank holiday weekend when i have somespare time. May have quick look into camshaft upgrades and clutches/flywheels aswell. Big job brake out
