New crate motor woes
Just to let you know about quality & issues from the old days;
In summer 1970, I bought a 69 Swinger 340 4spd 3:91 with 13,000 original miles. The car was mint, adult owned, all stock right down to the hubcaps.
I was on the highway going to work and another 340 dart was in the slow lane....being teenaged idiots, we both punched it at 60 mph. A HUGE plume of oil smoke came from BOTH cars as we got past 80-90 mph!
I never complained about that on the 5 yr, 50.000 warantee, because I was fighting about clutch problems and an annoying knock in the engine. I don't even recall if they fixed noise, but I saw it apart for some lifters at the dealer. Basically it was a nice clean car that went better than anything I ever had, but it wasn't perfect mechanically. Despite those few things, I'd take it back today with a big smile :goodman:
If that was my crate motor, i would look into what was said about the breather/pcv, plus put some miles on it before condeming it. Also, try a different oil type, too.
