I have a 92 prelude SI aws..New belts, head gasket, rebuilt head with 170k on the block. I was driving home the other day around 60mph when my car bogs down then i hear loud metal scrapping noises, sounds like major valve tapping. I'm like 1 mile to my house so i try to make it...i then notice my oil pressure light blinking and finally when i get to my drive way it shuts off. I check the oil level and it's fine...i try adding oil to build up pressure and try it again in an hour....it turns on fine the pressure light is off but the valves are tapping like crazy...

I'm pretty sure it's the oil pump but i dunno...any suggestions, thoughts or comments?

 

Anyone? It's a loud fast clicking sound coming from the engine

 

boy, your guess is as good as mine. esp w/o hearing what it's doing. broken rod? is your hp 1/4 less now? more whie smoke out of the tail pipe? that's what i'd image you'd get if one of the cyl were dead.

oil pump my guess too.
