Erm well not really as they need to sort a few things and I only want this off them, if it fails it's a rebuild so would cost them more so surely you would have thought they would sort it
you will be looking at £600+ for parts an labour to change the dephaser. Also you wont want a normal garage doing it due to the specail timing tools required. Also, dephaser pullys very rarely collapse/expode. The just get noisy. I dont think its a dephaser problem as they dont normally sound tappy, they sound chattery. search youtube for some videos.
