Yes sir

Can you draw where the catch can would go?

hmmm.. i capped the tee of on my det and so much blow by gas, oil shoots out of the dip stick when i mash.. lol

Like which one? An aftermarket one?



Thats not good, you just increased your crank pressure, this is robbing you of HP's.

Read up about crankcase ventilation and pressure here.

i took a quick look into my engine bay for this, but i dont have any of it. is this only a high port thing or?

RR engines have the oil gas baffling in the Valve cover. Ever notice that its taller than the ones on the older SRs?

Nice write up, but what is up with your fan blade?

RR's and VE's have the oil separators in the valve cover built in. This does make it harder to reroute the blow by gases. An after market catch can is probably needed, or at least wiring up the highport/lowport one.



I cut it so that it wouldn't slice off my O2 sensor hehe.
