What's the advisable time to change the timing chains?
If I remember correctly, every 80,000 KM the chains and every 40,000 km the belt

I thought overfilling could damage the catalytic converter. But I guess you removed the cats for your track Ghibli, so not problem in your case.By the way, overfilled oil is not a bad thing on the ghibli. The Cup Race cars were overfilled by the best part of a litre to reduce oil surge issues. We have run our track ghibli overfilled for about 8 years.
IMO, the lack of compression is more likely to be valves or, more likely, head gasket if you can feel compression coming out through the dipstick. Just a thought.
There is a Maserati refurbished engine at Meridian Modena in Lyndhurst advertised on Pistonheads parts section. No price but been for sale for an age.
Depending on your level of skill, tools, or the availability of a friendly workshop, I would take that engine out and strip it to bits to find out what is worn.
You can then budget the cost to repair it and compare that cost with a used engine or a refurbished one.
A used engine is a shot in the dark and a refurbished one will depend a lot on who did the refurbishment and what is the warranty given.
If you overhaul your engine at least you will know it's properly done.
Is the only issue oil level increasing and the odd cel?
I would take an oil sample and send it off for analysis (search web for companies)
Indeed there was a bigger pipe in the lower-left corner I didn't see... only after trying to pull it off. It was quite hard to remove and this action caused some small peeling paint / dirt to fall into the intake ports. Luckily only the 2 back pistons were open, so duct-taped a straw to a vac and sucked everything out I could. Lesson learned, blow everything away with compressed air.
In the end I've used Loctite 577 for sealing the threads, also for sealing the coolant temp sensor.
For the o-rings I've used this set: http://mrinjectoruk.co.uk/Weber-IW-...-Filters-Pintel-caps-6-cylinder-P3212676.aspx
Spent quite some time on the weekend to clean up the manifold, remove all the loose paint, etc. Will repaint later when the engine is apart. Hopefully I'll put back everything tonight.
Just did the manifold removal on Project 3200. Take your time and make sure to order some replacement bolts as they just rust. I went for some black rust proof bolts and they seem to do the job. I did the starter replacement which even for my limited mechanical ability was quite easy with the right tools and excellent forum guide.
