Great DIY! I am replacing the Chain, guides and chain tensioner on my wife's R18 tonight, I am going to put a DIY together with ALLDATA instructions as well as photos from my work. I will use your write-up as a format reference for mine!
Depends how quick you are and what tools you have, something a shop could do with a lift and proper air tools in an hour might take you at home with a jack and hand tools 5 hours. Also jobs like this dont take long if everything goes OK. But when that last bolt shears off at the head and you have to get that bolt out to drive the car, it always takes longer than expected.
I'm in the process of changing my stretched Timing Chain.
Had the P0341 Code and the car was in limp mode. So...
Chain Cover is off. I only have a small window of time to work on it till my next days off. Otherwise it would've been finished.
I noticed my exhaust cam was off a few degrees when checking the cam and crank alignment..
Im just hoping none of my Valves are bent.
I dont know if any modern motors with their high compression and cam specs are non-interference. The K series is definitely an interference motor, pistons touching valves happens all the time when things are not done correctly or if something lets go.
