Hello, my car makes the classic vvti rattle at startup, but sometimes it does a similar sound, and not only on cold starts but also when the car is warm and turned off for 1 2 hours, so im thinking replacing the timing chain in hope i get rid of the noises, i have found a Skf timing chain kit with the camshaft pulleys, and many more without, but they all say it fits 2gr-fse engines, are there any differences? Im checking the codes and mostly look the same, anyone with any kind of experience on timing chains?

Car is is250 2008y, 320k km on it (service history uknown tbh i dont think it was mantained well) P. S. The car makes a ticking soubd also when drivibg, like the fuel pressure pump but louder Any advice? Thanks
