Try Joe Imbesi at Dontex in Vermont, a search under his name on the forum should give a phone number or they are in the phonebook.
Joe will give you his opinion if there is a problem and also a probable fix, and what he doesn't know about Zeds isn't worth knowing. :bow2:
I would say rod knock. Its rebuild time. My car did the same thing, started with a small tick, ended up loud.
Start with the basics 1st before you consider rebuilds etc. try changing to a 20W 50W oil. It is hopefully just bled-down lifters which should come good with correct weight oil. Give it a few cold > hot > cold cycles over a few days before you judge if this was successful. If nogo, then look at next things such as VCT solenoids ect. Last resort is internal diagnostics such as compression/load balance test. Suggest you go see forum member Tektrader who will steer you in the right direction.
