I have a similar problem with a 380 I picked up last week. Except it's the left hand bank with number 5 cylinder clicking away. This engine also has a suspected cracked piston but that is not a worry yet. The engine has great oil pressure and leak down on a couple of cylinders was less than 5% so it appears to be fine other wise.
I changed the left hand tensioner rail as the existing one was broken in half and the cam was one tooth out ,talk about a close shave!! .
The PO had spent $6000 in 2006 getting a broken chain repaired ...but... who ever did the work didn't bother changing the oil filter. In fact it appears no one has for the last 20 years.
The filter has disintergarted sending bits of fossilied paper through the upper cam oil ways blocking them off. No oil pressure to lifter gallery or the cam spray rail is the result.
It looks as though i will have to either strip the engine ( I really don't have the time) or pull the cam and poke something down the oil ways to clean out the crap.
My left hand cam is worn out though ,so i may just replace it .
BTW the thickest cam pacer is 6 mm so the 5mm is OK.
This is a picture of what the filter looked like when i pulled it on Friday. Some people want their ass kicked.
