Just like my "lifters" tick but only for a few seconds on a cold start. It will last 6-10 seconds when my oil is low. A properly working tensioner on m62 you won't hear the timing chain on a cold start.

N62 they switched to two chains it's far less likely to have the problem but I would still replace at 100 k miles and every 40-50 after that.

I was talking about the serpentine belt tensioners not the chain tensioner.

As far as the chain tensioner, in spite of all the horsepower and torque gains from engine mods, I have not changed anything but the chain tensioner to get the redesigned version. I have the parts to change the chains and guides and proper tools but don't intend to do the job until there are some symptoms or when I do some other mods I am planning, even though some have said they had no warning. Mileage- 122,000 or so. I have a look with camera scope every once in a while and I always look for any indication the guides are failing when I change oil and filter.

Well new INA chain tensioners are on order to install in both the E53 and E38 motors - can't hurt.

Finally got the beast on a lift and was very pleased on the underside. Some oil leaks (as expected) but I think the major problem is actually the front PS lines more than any oil leak on the engine. Unfortunately that part is only available from URO so I had to get an NOS one off ebay.

Pulled the lower oil pan and everything looked great. No timing chain particules and only a *very* slight amount of sludge.

A buddy who is an ASE certified tech (and a bimmer enthusiast) went over the car with me and was surprised how dead-silent it was on cold-start.

So I think chain guides are fine. I'm going to keep up on oil changes, keep an eye (or ear) out for any noises and just enjoy fixing it up.

Good plan.

I didn't go with a stock looking unit. I wanted a bigger screen. I was concerned it would look weird but to me it looks like factory install

Nice pickup OP. Great price for it too especially with the goodies on it. Happy modding, lots of options for audio upgrades in today's market.

I'm not a fan of that unit as it sticks out of the dash like a grafted on tablet. Though I'm sure visibility on it is better than the one I run which suffers severely from sun glare.

As for appreciation, as with all enthusiast BMWs, the 4.6 and 4.8 will go up. Has already started. Don't think they will ever be truly a collectible high dollar vehicle excepting collection quality and mileage examples.

With enthusiasts, tasteful mods won't devalue the vehicle either. Which is nice. Seems we all tolerate "resto mod" vehicles very well when shopping, much like the classic muscle guys do now.

I have the Avin unit on my 3.0i and I love it. Smart of them to include the i-BUS app so it works with the DSP.

On this car I'm going to go BlueBus I think. Like my M5 I just want to keep it stock looking. I"m not pressing this car into daily duty (that's what my 3.0 is for) and for some reason I'm feeling very precious about keeping this car as original as possible. The factory screen is minty clear, so might as well just keep it.

Consider adding a BlueBus unit to give yourself streaming and great bluetooth capabilities in the X. It plugs in where the 6Disk is located in the rear left. I still have a completely stock head unit/audio system but now have all the upgraded BT that I was hoping for. I'm quite happy with it and it was very reasonably priced.
