engine ticking only when warm - AutoRX?

[czah]

Hi

I own a 2000 year Volvo v40 with 2.0 liter gas/LPG powered engine, 190000 km. Some time ago, I noticed that if engine warms up to the operating temp, I can here a ticking sound when idle (3-4 ticks per second). When engine is cold it runs quietly. I have no pressure problems, no power loss, everything is ok, but this ticking is something Im afraid of.

Last time I decided to top up the oil with Maxlife 10w40 (there was Mobil semisynth 10w40) , and noticed that cold start is quiet - earlier I had this "tick tick" noise for 2-3 seconds when starting. But when only engine warms up (after about 15 mins) I can there this irritating ticking when idling.

Do you think auto-rx will help to solve this problem? After auto-rx cleaning - can I use maxlife oil, or it has no sense then?

ps. it takes about 0.5 liter of oil every 3000km - it doesn't burn it, but I can see a leak on my timing belt cover.

I'd give it a shot, it helped my engine knock for sure. I have to do another treatment because the knock is starting to come back. It's a 20 plus year old motor, and I don't think it was well maintained. It probably needed a few ARX treatments. And as a side note, Autorx is always in stock and doesn't have the same issues as many of these other additive companies. No excuses, Frank will take care of his customers.

RX sorts noisy HLA's. Run it hot and hard.

Why don't you just change the oil?

worth a shot- I assume it has hydraulic adjusters for the valves-

if you think you have "noisy" valvetrane ticks.. listen next time an older isuzu is next to you in traffic, lol. their hydraulic adjusters are notorious tickers... but they can tick for hundreds of thousands of miles and still run strong. ARX can help quiet them down if you catch it soon enough, before they are totally collapsed or worn down. ARX helped mine a decent amount. It's not perfect, but a lot better than it used to be.

Clogged passages are making that lifter get less flow when the oil thins. There's enough visc to make the open ones still provide enough backpressure when cold. Auto-Rx should clean it up ..but may make them all tick, albeit quieter, at low speed.
