[Ultra-Orange]

So, "Actual Size"s (1993 Geo Metro XFi) previous owner wasn't much on maintenance, the interior was coated in dust, the engine compartment was black with grease, The oil filter had to be pried off with a pipe wrench. My guess is that the only fresh oil shes seen in some time is from "topping up" the engine (oil leak between block and head, top end gasket rebuild going to be a future project).

and... the engine rattles... all the time. more pronounced when accelerating. sounds like a diesel. I have Changed the oil (5/30), Adjusted the timing, cleaned the plugs,cap, and rotor, Sprayed out the carb on the car( no air filter and the inside of the air cleaner filled with grease/oil/slime).

Its not a rod knock. Its not lifter tap. Its not spark knock.

Help!

Thinking about seafoaming the engine (vacume line/ crankcase). Thinking maybe oil deposites limiting oil pressure to the top end. but that is pure congecture. really kinda grasping at straws.

anyways. all help/advice appritiated!

Thanks in advance!
