So I have a 2005 gtp comp g, basically all stock. About 2 weeks ago I changed the LIM gaskets, coolant elbows, and an oil change everything went off without a hitch! After completing the car, it sat for a few days. I went to drive it watched the temp guage and it seem to be driving fine! I drove it for roughly 4 hours that day, on my way home later that day I pulled up to a stop sign and it started making what I think sound like loud lifter noise and the low oil pressure light flickered on, so I pulled over turned the car off and checked the oil. The oil was fine not low, not milky and no metal shavings!! so I limp it home (was around the block from my house) get it into my garage and it seem to have quieted down some and seem to have been running better! so I leave it in the garage go to fire it up in the morning and the noise is back and the oil light is on, on the dash !!!! I'm baffled maybe a collapsed lifter ?? Please held any insite would be greatly appreciated !!
