OK.. so Im running in a rebuilt 318.. basically just a touch over stock.. slight boost in compression.. better factory intake and a 4bbl..
About 300 miles I put 10W30 mineral oil in, then about 500 miles in and 80 miles that day I notice it running rough on the highway.. and then in traffic slowing down it's more noticeable.. its got 4.11 rear gear on a 904 auto so revving between 2000-4500rpm peak..
next day I check the oil and it's REAL LOW.. I grab some thicker oil quicksmart and overfill the whole can.. runs a bit better. I get home and see there's a big spray on the front of the motor and all down the underside.. also the inside of the air filter cover.. where the breather tube runs in is stained dirty.. and the top of the carby too. It runs a bit rough and hesitates a bit but OK at speed.. seems to be holding the oil..
I take it out for some longer runs.. and it seems to be leaking/weeping on the front of the engine on the drivers side from when the intake meets the block or head and perhaps at the head a bit too.. changed the oil and filter again.. with a thick oil
Besides running a bit rough, and leaking a bit its clearly not spraying out.. but geez not what you want after the $$$$ of a rebuild.
What the F&*( happened is beyond me.. but perhaps a surge in oil pressure from a oil pressure relief valve that stuck/came unstuck... only thing I can think off to cause the massive oil loss that seems to have toned down to a dribble.. surely the thinner oil's no to blame??
any ideas before I do something stooped?
