The timeing chain is not to bad to do the first time i did one took me two days <img border="0" title="" alt="[Mad]" src="images/icons/mad.gif" /> That is a long story but i can do one in 4 hours now if you need to do one just post back here and we can walk you through it I would start with the oil filter That is a know problem with them I run a K&N but you can run a chaeper one just get a anti drain back type If you do the t-chain i would get one with the metal guides
