    I have done a fair bit of searching to try and find discussions about my particular engine noises, but haven’t found anything quite the same (yet).

    From about 1900 to 2000rpm I have a nasty pinging (at least it sounds like pinging to me). It may be worse under load (uphill acceleration), but it’s pretty much always there when driving. It doesn’t seem present when stopped and trying reving it around that speed.

    I have possibly the same sound some times when cold, at all rpm, and while idling/parked. This goes away once warmed up, sometimes it even goes away if I shut the truck off before it’s fully warm and restart it (after driving for maybe 5 min, sound is still there, shut it off, immediately turn it back on and the sound will be gone), so I’m not sure if it’s the same thing or not. I have gotten under the hood and checked this one out (since it’s present while parked), and it seems like it’s coming from the front of the driver side, in the timing belt area.

    I have done nothing to the engine since getting the truck (I think I’ve put under 2000km on it), prior to that the original owner had it dealer maintained, the timing belt was done about 50,000km ago, it was up to date on oil/filter changes.

    Currently has about 320,000km on it, fully stock. I didn’t notice the sound when I got it, or for the first couple months, but the weather was warmer then, and the exhaust was rusted and a bit shot (louder), so maybe I couldn’t hear it. I have replaced the resonator and muffler with oem style Walker components.
    I use Co-Op and Mobile gas, 87, and admittedly haven’t tried a higher octane- I pretty much get all my gas in 20L jerrycans, so I rarely ‘fill up’, I’m usually around 1/3 tank.

    I’m tempted to dump some Seafoam in, I’ve used it with some apparent success before, probably can’t hurt, but I have doubts about it fixing these sounds.

    I have read something about the timing belt tensioner going out, can anyone tell me more about that, symptoms, sounds, etc?

    Anyone have any thoughts or advise on this?
    Kinda long post, thanks for reading.

    After 4 to 6 weeks of sitting around gas combustibility reduces as it becomes stale, and maybe that's reason for engine ping.

    I say go the easy route first. Fill the tank with high test fuel to 1/3 level your normally at and add 20oz TECHRON Concentrate Plus Fuel System Cleaner, or do the Seafoam method that many people prefer.

    What type of oil is in the engine?

    Synthetic or dino?

    Sounds like the temperature effects the sounds you hear and the sound goes away after engine warming.

    Start cheap and fill with your regular gas normally used and put in some SeaFoam gas additive. This is your base line.

    Move on to a quality detergent synthetic to get the insides cleaned up. This takes a few quick oil changes. Or, use LiquiMoly engine clean for faster results.

    Keep the truck tuned up. Are your plugs good? Tight in the hole. These engine plugs get loose after 6-8k miles.

    Check the coil packs for cracks.

    These are all the cheap and easy things. From there its mechanic time!

    I’ll have to check the service records and see when it was all done last, it was well maintained, but that doesn’t mean things aren’t ready to be replaced.
    Thanks for the feedback.

    Checking service records is fine but nothing is better than than physically pulling and checking parts when trying to solve an issue.

    Okay, dug out the records I have, lots of service, regular oil and filter changes (synthetic, a few different weights, mostly 5w20, some 0w20, mostly appears to have been Mobil 1), no spark plugs that I saw.
    So, can’t hurt to change those.

    I did some searching, but am still a little uncertain about what plugs would be best, Denso or NGK? Iridium, platinum, copper?

    In my opinion either Denso or NGK plugs are best for these engines. I personally use NGK BKR6EYA plugs. That is the recommended number listed in the owners manual.

    I also think the oil that has been used in your engine is too light in weight. I would use a 5w30 in winter and a 10w30 in summer. I am also a believer in "High Milage" engine oils. They do make a difference. I have experienced less oil consumption and minor oil seepage disappear. I use it in everything with over 100,000 miles.

    I will see if that plug is available next time I’m in town; I’ve never had problems with Denso or NGK in other equipment, always good to know the right model.

    I haven’t had the truck long enough to notice any oil related issues, all the prior service was from the dealership. I’ve never used a 0 weight in anything before, will probably do with 5 and/or 10 in the future with this truck.

    Thanks

    Good advice on the plugs above. Definitely get back to 5w-30 ASAP.

    Mobil HM Synthetic works well.
