Oil tank
ss4:
okay thank you.
ts39256:
I hope this question doesn`t sound foolish. If your running Donovan valve covers on a early Chrysler hemi and run burn down tubes in place of the front set of breathers, do you block off the rear set of breathers? I know the engine needs to breathe, is the puke tank alone enough?
dreracecar:
Yes, you would block off the rear, Another thing that is starting to become prevelent is to run a breather line from the valley cover. Since the pushrod holes are so small and blocked by the pushrods and oil, the motor has a hard time breathing. Taking it from the valley really helps.
ss4:
sorry for so many questions on a simple task.
From rules for a 8.0 dragster, how does the clear tubing have to be secured. are hose clamps acceptable? I am specifically looking at the tank side. plan was to use slip on with hose clamp and possibly the samething on the valve covers. I really would like it to come of the front face instead of top but I certainly get the concerns.
Also I am going to run water in the block (no pump) and was going to plumb a -8 line to the same oil tank and possibly put a 3ish psi check valve in line. thoughts?
dreracecar:
Hose clamps are fine, some class prefer that 2 to be used at each end.
3 psi is not enough try 17psi and plumb into headers, make sure to drill 1/8" drain holes in each tube at the lowest point.
