Teir 1 Scrub

Now wont start which is another issue I removed the oil control valve for vvti cam and no oil has been in there since i ran it a few times, probably why cam is knocking - no oil Honestly thinking it's time is up

I recently bought this car as a runner with vvti issues With possibly crap oil which had formed sludges and caused a blockage (not 100% sure of degree of damage) The car currently runs and idles/drives nicely however, it has started the knock on the vvti cam gear which gets worse if you rev I have bought new oil control valve but vvti still isnt right Any advice for a new owner would be appreciated
