Thanks for the advice. When I looked into it, I read about more horror stories with that type of product than I have success stories, so I will avoid that stuff and stick to frequent oil changes. Just changing the oil every 200 miles or so worked wonders with my old Volvo, so I have no reason to doubt that just doing frequent oil changes will clean things up nicely in my D2's engine as well.Just DO NOT use any type of engine flush in the oil. If it is gummed up it will washable the gunk through the bearings and other places that you do not want it to go.
No they don'tmiracles don't come in bottles at the auto parts store (-;
Thanks! I already love mine, and they are definitely something special.Congrats on your D2, nothing like them; my 01 has 212k on it with no end in sight. It has a tick that started when it was about 5 years old, appears in mine if I’ve lazily commuted a few days in a row (noticed long ago that it was absent after an hour or more of interstate speeds, which generally puts you at around 2400 rpm for prolonged periods; absent interstate running, spending a day or two in sport mode or even just intentionally running a few miles in 3rd gear at 50mph cleans it up. I use Rotella and change it every 3k miles (more often in summer if running in super dusty conditions) and I really think clean oil and avoiding high engine temps are the keys to longevity in these engines. An UltraGuage is a great addition to keep a good eye on engine temp and oil pressure - and if you’re going through the truck as time and money permits, I’d recommend a 180 degree rover thermostat at the top of the list (also makes those pesky head gaskets last longer). Anyway, for my truck, I’ve decided through the years that some occasional increased rpm driving (nothing dragstrip nutty) is needed to perhaps throw more oil into the top of my engine - tames the tick and smooths out my engine. Enjoy your D2!
Yes, the Rotella T6 Heavy Duty Diesel oil - seems to strike a good balance of cleaning and lubing.Thanks! I already love mine, and they are definitely something special.
It seems to me like these engines like being driven somewhat aggressively. On days when I take it easy, the noise doesn't go away, but some high-rpm driving for a little while makes the tick disappear and the engine overall runs a lot smoother and quieter.
I found a mechanical oil pressure gauge laying around in my stack of parts that I am in the process of installing. My truck is right in the middle of the oil pump failure VIN range, so keeping an eye on it seems like a good idea.
I re-did most of the cooling system when I bought the truck, but didn't do the thermostat. I will definitely be sure to pick up a 180 degree thermostat - it seems as though these things like to get quite hot. I'd much rather shell out a few bucks now for a new thermostat than hundreds or more for new head gaskets down the road. I will also invest in one of those OBDII-Bluetooth adapters (super cheap on Amazon) that gives readings to an app on my phone to make sure it doesn't get too hot. From what I've read, the factory gauge is not to be trusted.
It's certainly reassuring to hear that your truck is still going strong for all these years despite the tick.
I have read that a lot of people recommend Rotella and generally have good things to say about it. From what I can find, it seems to be available primarily in a diesel-engine blend. Is this what I should run, or should I seek out a gas-engine version instead?
Thanks. I'll use that next time I change the oil.Yes, the Rotella T6 Heavy Duty Diesel oil - seems to strike a good balance of cleaning and lubing.
It also occurred to me driving in this morning (no staycation for me this pandemic, essential business grinds on) that I haven’t heard the tick since I recently replaced the crank position sensor - may be coincidence, but logically makes some sense that my old one with age and wear may have became less precise and possibly created some slight timing issues that in turn caused a tick.
Will do. Thanks.I would. Order a new gasket first.
Sounds like a plan. My thoughts on dropping the pan was to clean up sludge down there, but the oil seems to be doing a great job taking care of that on its own. I am always keeping a close eye on it, so I will let you know if any new noises pop up.PERSONALLY - I wouldn't worry about it till it's cleaned up. You have no clue what's going on in there until that happens. Honestly, even dropping the pan right now is going to be a waste - you know you have that crap in there right now. I wouldn't waste a new gasket etc until you are sure things are cleaner? Once you've cleaned it up, you'll know what's new. Just stay the course...
Once it's draining relatively clean on those changes, then we can start to figure out what's going on there. Just pay attention to the other sounds it's making in the meantime.
That's good to hear. I'll run that next time I change it and report back after some miles and a few changes.Lifter all day. Had the same issue. Run some Shell 15-40 through it and see if that fixes it. If not, pull the top end off and do the lifters. I had two that stuck and made the same noise. After replacing all, it went away for good. 15k miles and no noise.
Also you cannot run 10w-30 in it. I did in Canada and it killed my cam.
I ran Rotella 10w-30 (Spring thru Fall) for 10 years in my current truck and only switched to 15w-40 [also Rotella T5] since moving to the desert. I never had any issues with 10w-30 or any fluid that was recommended by the Rave, as long as it was changed before the major annual temperature variations.Lifter all day. Had the same issue.
