i have a rdt that runs from my valve cover down the frame and dumps out. when i am sittin at the stop light i get quite alot of vapor that comes out and then i throttle up to go...it is like theres a cloud left behind me..how much vapor is too much? what does that mean? and how can i fix it?

ok just checking... do u know why it does thaat though? would it be ideal to add another rdt on the passenger side from the valve cover? also with ur truck running when u take off ur oil cap do u get vapors shooting out from there?the only reason Im wondering is that i only have the one vehicle till winter is over(too cold to ride motorcycle) and dont want to be stranded

From what others have said, venting just one valve cover isn't enough. I'm not sure if there is poor exchange between the two top ends or what, but if you just have an opening in the valve cover with no "element" to help knock down the oil from windage/rocker arm then you are probably venting more than you want. Mel has always posted about the banks adapter that goes on the front of the IP gear housing where there is a block off plate. I wouldn't be hard to make one either.

well the thing is he has a hypermax turbo same as me and in the destructions (instructions) it says to put you cranks case vent into the valve and i followed the destructions as they said and then decided to put a rdt on when i got on to this wonderful site thanks guy

I had that same problem. So after getting some info from a few guys on here, I rigged up something. I mounted my CDR valve on my intake tube after the air filter. Then I ran a 1 inch rubber line from my valve cover to the CDR. I dont get the vapor anymore and it seems to run great. I will try and post some pics tomorrow when I get home. hope this helps you out.

Why not let the "vapors" com out the exhaust pipe? Weld a 3" piece of 1" o.d. pipe onto your exhaust pipe (probably towards the rear of the trans) and put the loose end of the RDT on it with a clamp. The exhaust will help to pull the vapors, and it will exit at the rear tire.

That would work, but I'd put a check valve on there or you will end up putting exhaust in your engine. This has been beat to death in other threads, but there is a kit that has the valve cover vent, the exhaust pipe and check valves. I have one an have posted information about it a few times, it's MR. Gasket.

It's a common report of RDT guys. You hear stories from time to time about some concerned motorist rolling down their window to tell you "I think you truck is on fire!"

But, most guys with RDT will tell you that is common at stop lights/signs.

Yup, welcome to the "Hey yer truck is on fire" club.

I made my own rdt venturi setup from the info Scott posted up. Works great!

 

[coletrain777]

Can someone post the part numbers for those RDT to exhaust kits, I searched but can't find any part numbers.

 

[skintbackfarms]

Anyone have some pictures of doing this. I would like to see. Thanks.

Been there. Done that. Had the valve cover with a hole in it on my shelf to prove it, until I sent it to Joe Lewis.

Get a new valve cover.
