Makis,

You should have the skills to do the job.

Prepare by getting an engine support for the top of the engine. You can "get by" with a DIY support made out of 4x4" timbers if necessary.

Get a mechanic's stethoscope and probe the valve cover bolts, exhaust flanges and intake flanges for lifter tick. If the noise is not there, probe the oil pan and lower crank case for rod bearing knock.

I tried to get a stethoscope today but could not get one at my local shop. So decided to to remove the Pan to have a look. Quite hard work I must say. I am not sure if I should be happy with what I saw. The rod bearings look just fine new really after 178K. No vertical play, but there is some lateral play (direction of the crankshaft) and all exhibit the same play. So I would say this looks normal. At least I now the noise I am hearing may not be terminal. Time to get that stethoscope from ebay as I saw there quite few. I can wait as It will take a bit of time to get the engine back together.
