I need to replace a cracked intake/exhaust manifold on my '01 4 cyl 3.0 motor. I saw a thread on here that was never answered where the guy asks if he can use OMC part #3854045 because Volvo part #3858870 is a replacement for the OMC part which I take to mean that they're interchangeable. The price difference is about $200 or so.
