On Sunday evening I noticed a different whirring noise coming from the engine, a noise that you would usually associate with worn bearings in the alternator or power steering pump for example.

After some investigation with my stethoscope I concluded that the noise was coming from the behind the chain cover on the right hand bank (as you look at it) of the engine. This to me could only mean one thing....the right hand chain guide had failed or at least was failing. Unfortunately (and admittedly unwisely) I had no choice but to continue driving it until I could sort a different car out for using to work since I work 25 miles from my home. All my other cars happen to be off the road atm too unfortunately.
Anyway....120 miles on from Sunday evening on my way into work and the chain guides properly failed and now my engine has developed the full on death rattle. No video yet but I'm sure you can imagine what it sounds like! Fortunately it's still running on all 8 of its cylinders.
On the plus side....least I get to tear down alot of the motor and do all the jobs thats needed to keep it going for another 100k+ and give it a well needed clean up at the same time.
Off now to collect a list of parts required....anything else people would do at the same time? I remember reading something about a part for the CCV system?
Full timing chain kit including guides and tensioners and seals
Valley Pan Gasket Kit
Oil/Filter
Copious amounts of brake cleaner
Water pump, alternator & aux belt tensioner have already been replaced recently. |
Sorry to hear that. Engine failure is always sad.
Every time I see one of these posts, I am so glad I picked M54. I got 187k out of it before it really became un-drivable on a daily basis.
That said, if you can do the work and you have the tools, how bad really is the timing overhaul on the M62 or N62? What's the cost? Assume no cataclysmic valve/piston contact, is it that terrible? The timing overhaul on the M54 costs a higher percentage of replacement engine cost, I would think, given what M62s and N62s still go for in the secondary market.
I see a ton of 740s, X5s and even some Rovers with those engines for sale that say they have timing chain rattle, but the rest of the car is in good shape. They can be had for very cheap.
EDIT: I just watched the vid, that sounds awful.
