All good comments. I ended up selling this vehicle not long after the video was taken. No issues were ever found, although I do think the engine is simply old and could use a refurb. It always ran well, but I never did get it to pull as much as I think it should have. Also, I was a long way from really figuring out the HVAC system on this vehicle, and probably would have needed to do some more work to be satisfied. In the end, I owned my dream car! I built it with a budget to what I figured I could realistically do, and when I sold it, I was really happy to see it going to a family that will have some adventures in it. I'm sure I'll see it around someday, since it is only an hour or so away.
I’ve a 300Tdi with 195k miles on. Mine sounds exactly the same!! There’s plenty of power, no smoke and runs lovely apart from this sound. I was speaking to a guy earlier this year who used to own a Discovery 300tdi and his was the same, said he never got to the bottom of it. To be honest I’m thinking fuelling as some have already said. Anyway glad it’s just not my truck!! 😅
Next to valve cover, a steel oil return line runs , on turbo side. This is often loose and makes same sound, caused by obvious vibration. Take some rubber tape and make a spacer to fit between valve cover and this oil line. Common issue but will cause no damage, just annoying.
Mine has a similar tickling noise. Replaced vacuum pump with a new one (Wabco Made in France), the tick tick is still there. I've read somewhere about conrods problems! Hope it's not my case!!!!
Wow! Thanks for replying to this! I've been trying to get people to hear it, or to get it recorded for a long time. I'm glad you think it sounds normal, but I'm curious about possible combustion knock. Assuming the timing is correct on the belt, and the pump, what could cause a knock in a single piston? (In this case, it really does sound like it is coming from #1.)
@@sandrinifontes476 just recently replaced it i think i am one tooth to advanced evidently they ring like that when advanced on the diesel pump im gunna reset mine next week !!
I've not found any actual problem. The engine is running as well as ever, so until something actually goes wrong, I won't be pulling things apart to search for the origin of this noise. I'll see if I can remember to post something here if I ever come across anything.
@@rvrnnr987 I am thinking that part of my problem is 10w40 oil. May be to thin. Will change that since it only makes noise when the engine starts to warm up
Nope. It never got worse, never went away. Mostly, I was the only one who could hear it, and usually only when it was in my garage. I've sold the 110! Turning my attention to my '65 Seires IIa that I've had for 20 years.

Sometimes injector can cause knocking if spray pattern off. Blocked nozzle
I would check the valve caps. Maybe. Or bad cumbustion knocking on one cylinder because of injector problem?
Its the setting on the pump to advanced !!! Needs to be reset back to factory settings just about to reset mine ....
MINE WAS DOING THIS I PUT INJECTOR CLEANER IN IT AND IT SORTED IT BUT I HAD A DISCOVERY 300 TDI AND THE VACUME PUMP WAS MAKING THAT KNOCK
sounds like the 300 tdi right down to the metallic ringing. Perhaps it is just a combustion knock?
