While conducting a cylinder pressure compression test and leak down test is well-intentioned, as a well-meaning makan gaji mechanic (of which I'm not one) I would counter-suggest you to abandon the idea basing on your disclosures thus far.
Even if you're facing a small drop in engine power or pick-up (which you are not), I would then suggest you vroom vroom the car at high engine speed of 4000-5500 rpm periodically (aka Italian tune up) at highway speeds which would surely improve the smoothness of running engine.
As others have suggested, don't touch it (like un-needed top/major overhauls) and only replace 1 or 2 parts as and when the
need arises, not so much of what you
want to replace.
Keywords: need vs want.
Thank you @zeng for the needed to hear comments. Yes I do have slight leak below the radiator, nothing major as mentioned so I would do the seal change, water pump, timing belt and etc and only change anything required.
You are right spending on things that’s not needed is just gonna make some mechanic happy but when it’s not needed in the first place.
I would like to also ask on what kinda shop should I look for to do some tidying work on my cables, wires, and pipes in the engine bay coz it’s kinda needs some cleanup to change those reput cables and change some wires that’s in bad shape due to the wearing over 20+ years.
