You're close; three! But the number of belts isn't the issue. The challenge is that when the primary belt is released, all four camshafts move. Two sprockets then have to be held in a precise position (against valve spring force) whilst the new belt is threaded around the water pump, idler wheel, crankshaft and hydraulic tensioner. Trying to do that single-handed using Tippex marks really is a folly.

Thinking about it, on the twin cam engines I have worked on, there was usually a way of locking the camshafts, either with a toothed insert between them or bolts through a spoke into the head. I always tippexed marked all sprockets, just in case I lost the timing/dropped the locking device. Some timing marks are very indistinct.

Talked to my mechanic and he also said that he can do the job without the tools but you can't get the timing 100% flawless without the special tools and I studied a little the issue and it makes perfect sense. He recommended me that I find the tools and buy them because at his supplier they cost about 250 euros, and I found them as new, never used, from a source I have in my home country, Romania. At the amazing price of 136 pounds plus shipping. If anyone is interested, I will buy and send them to each member that is in need of them, worth every penny as this is a job that everybody will eventually have to do at some time.

I'm never even looking anymore at chinese NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD- no matter what it is or what it is used for, especially if it's car related. Done that mistake for some times and it always costs you a lot more in the end.

To the OP - I have read of a couple of cases of one of the pulleys on the secondary belts failing. You will see that one is an ordinary sprocket, the other incorporates a vibration damper. Of the two instances I have read, the rubber part holding the inner and outer parts of the damper pulley had failed. I don't know if any visible signs of failure must be there before any symptoms arise. But it is a known although rare problem. Possibly it is starting to fail (or could be something else entirely).

Well the only logical hypothesis for the tappet noise would be either "clogged" or smudgy or dirty or name it how you want tappets because of oil residues or tappets wear that would be a cause, as you said, of an aging pump, which is highly unlikeable I guess and very rare, they rarely fail and when they do, you'll certainly know it haha. As I said, I added a Lukoil tappets additive which should clean the tappets and should be really good as I've read, but not even the slightest improvement to be heard. At this point it's still a guessing game, once the things are stripped down then I can see what's what. I ordered the timing tools and then I'll get to it, I hope it's just the secondary belts aging related wear causing the ticking and not one of the pulleys, especially the ones with the damper as you said, because they cost a small fortune
