Sean, The PRV-6 B-28F used in the 1978-1980 Volvos had "soft" cams and oiling problems that caused premature failures. In mid 1980 new hardened camshafts and improved oiling was added, this change included all PRV's built for the De Lorean. Unfortunately the negative reputation stuck with the PRV. Your De Lorean PRV will not suffer from these problems, no special precautions need to be taken. Regular oil changes and preventing overheating will allow your PRV to run for at least 200k miles.
