The 55 has done more sitting than driving lately (last 18 months). It was bought from a PO that claimed the engine was rebuilt. Block is clean and painted day-glo orange, so it has definitely been out of the car at some point. Strangely, it appears that the accessories were not replaced at time of engine rebuild. Why one would want to skip redoing $400 of acessories on a rebuild beats the heck out of me... When I start it, I hear tremendous lifter noise. Sounds like one and not all. Tap Tap Tap - not tapety tapety tapety. The first few times that the car came up to temp, the noise abated within a minute or so of operation and a little revving. Now it does not seem to be doing so, and a 3/4 mile trip around the block on car (no plates on it) yeilded no improvement. I presume that the car has hydraulic lifters? I don't know the 55 engine well at all. What causes lifter noise in a presumably recently rebuilt, but sitting forever engine? Should I just drive the thing and get it on the freeway before tearing apart? Oil pressure indicator says that there's plenty of pressure, and I'm wondering if the temp just needs to come up? How to diagnose without removal of the intake manifold? Kenyon Wills ----------------- http://www.imperialclub.com ----------------- This message was sent to you by the Imperial Mailing List.
