....well maybe the error was getting this big block in the first place, but anybody out there can tell me what the X is going on?
First off, this Ventura I picked up with the 72 Grand Prix 455, has probably been through the course, kid had it since high school. Way too much power, looks like a lot of bucks were put into it.
I took it 30 miles to a hang out car meet when I finally got it running and legal, was running on the hot side, hit 220. (Car has electric fan attached to radiator, ordered a JEGs shroud, on way) When I checked the fresh oil, it was a half a quart low. On the way back, it was a much cooler night, in the upper 40's, car hot again. Next day, oil now a quart low. The kid says it was always running hot, well thats because beside no shroud, he also had a 160 thermostat when it calls for a 195. Not good in Florida, he says he was always careful.[S Also the timing was a little too advanced.
So now, the past couple days, I am not seeing smoke, not seeing leaks, no oil in coolant or vice versa. Using half a quart in a 20 mile run. I open it up a couple times when I do this, but only for a few seconds.
Some say its a PCV issue, I have breathers on both valve covers, PCV in valley under intake, seems clean. Soot in exhaust appears normal, plugs not fouling.
Also, its got a valve issue thats noisy when cold, quiets down when warm, but I looked under the valve covers, saw these: (see Pic), not adjustable.
So what does you guys think is going on? I would think I would be seeing billows and lakes at this oil usage.
