vr v6 surf(problems)

[v6-surf]

ok my vr v6 surf is making popping noises wen idling and at higher(3000rpm'ish) makes a kind of pinging noise. its quite loud and sounds like a big exhaust leak, iv checked and havn't found one, it also happens wen under load at lower rpm, it was doing the same thing on the old vn engine that was in it about 3 weeks ago.
the oil pressure gauge reads prity low. its got oil and the oil pressures been the same since iv owned the truck, i did a oil/filter change wen i put the new engine in.

any advice or info would be great thanks.

Try looking for any set error codes in the ECU. Check any parts that were changed over from the other engine.Leads,coils etc.If the two different engines are showing the same symptoms, then its a big chance theres nothing wrong with the engine itself and that something else is causing it.
