egr won't do it.
how many miles? high miles on a abused engine sometimes ou have to run like 15w40 or 20w50 in it.
it might have had a noise in it before you got it and the seller put some lucas or motor honey in it to quiet it down. then you just changed the oil and now its making noise again with the thinner weight oil.
you can try fixing the niose by draining the oil. fill with dexron mercon tranny fluid. tranny fluid is a detergent oil and if you have lifters/ rockers that are clogged/gummed up from dirty oil in past the tranny fluid will clean it and restore the engine. its an old timers trick.
you want to let the car run for an hour or 2 sometimes bad noise you need to drive the car for a day or 2 with it in it. drain it you will see it oil will be nasty, then change filter & replace with a 15/40 or 20w50 for the summer high heat months. winter change back over to 10w40(the thicker the oil in winter the harder it is on engine on cold starts.
hope this info helps you.
p.s. i had a 99 v6 camaro that had the tapping noise and i did this procedure drove for a couple days w/ trans fluid. changed it put new oil in and noise never came back
