How do I check the oil pressure? I have had the car for 2 years and this sound has always been there. I thought it was normal at that time but lately I started to think about it. I've also used a fuel system cleaner but to no avail.

It could go for another 5 years without a problem. Does it perform ok? Is fuel economy reasonable?You can get additives to quiet noisy engines. Usually a fuel or oil additive. Ask at your local auto accessory shops. If there are several, check them all out and then maybe google the products they sell/ recommend to see which gets the best feedback. It's a wonder you didn't ask them to investigate when you were getting a service. Are you due for one soon?
I think one way to gauge the engine performance could also be to see when the gear change indicator shows up while accelerating. As per the manual, the indicator comes up to get the best fuel economy, so the later it comes up, the better. On mine, it shows up around 2800 rpmIs that reasonable? I have no idea what other 1.4 cars do.Reading that this could be an oil issue, I am also considering putting in an oil additive for a clean up. Any thoughts on that?

Yes, full credit to you for that
2nd attempt line dropoutBefore I was rudely interrupted, I was writing that the microphone is picking up every noise so it is difficult to be sure.As a best guess, your valve clearances are too wide. Given it has been going on for two years, I think your cam shaft is still bolted down, but check. This engine does not have lifters. It is overhead cam and they impact upon hydraulic lash adjusters ( HLA). It is possible that the oil flow to the HLA s is restricted.The oil is possibly the same line as the CVVT . On the FD motor there is a "sump like" plug on the back of the head. Under that is a gauze filter, it can get blocked and mess with the CVVT valve timing.
Mate, I'm on the other side of the world trying my best to interpret a cacophony of sounds and the suggestions made by your local experts .The valve clearance wont change. However at higher revs engine components move faster, therefore the noise changes.Is this a high Kms motor?Have YOU tried to narrow down the source of the noise? If not, make a basic stethoscope out of a short length of hose and report your findings.If it is HLA malfunction, increased revs may raise the oil pressure sufficiently to get them to operate. Therefore noise will disappear.If that is the case, oil additive / cleaner could work to remove oil sludge. However, filters will generally remain blocked by hard particles.. The FD model filter that I mentioned is actually on the end of the head R/H side. Have you bothered to look? Your service guys will not do that.
If you are due for an oil change soon why don t you try to add SeaFoam to the oil. Drive for a 2-300 km and drain. Put syntethic oil and perhaps add MOS2 or Ceratec addirive to the new oil. It did help with HLA on my Mitsubishi. And although my FD 2.0l is only 45 k ... is schwduled for the same procedure soon.
Local dealer once told me that engine flush or fuel treatment are ok, if there has not been lots of kms since last one, or new car. I would guess your car should be ok. If engine has more than 100 tkm there is a risk that cleaning will loose some large particles which may cause issues.Have you tried different oils when it has been changed? With older cars I've heard difference in engines depending on the oil brand.

It did get a lot better at that point, but noise remained. Currently it's running castrol edge 0w30 which apparently according to the manual is not recommended. I'm tempted to do a flush because the dealer I bought the car from cut all corners in putting the car in good shape.

I'll be using this instead (Danish site) : ServiceRens : ServiceRens 3It's a cleaner to be put in just before an oil change, idle for 20 mins and drain.

What corners? Its only done 58,000km (36,250 miles)
