    Moby's setup is great..

     

    just very very rich.. so be prepared for sooty plugs and poor MPG =)

     

    other than that.. Im still running his setup.. just with some VE tuning

    Crank Case Pressure to high?

    in Nissan L6 Forum

    Posted

    I got bored today, and decided to make a PCV evacuation system... similar to the stock setup

     

    I didn't want to drill and tap a hole in the intake manifold, so I did it the easy, cheap and effective way..

     

    With the turbo, and N42 intake manifold, the PCV valve hits the turbo outlet, so I had to plug it up with a large bolt..

     

    soo I put a filter on the end of the crank tube...

    since the oil and gas blow by blows OUT of the crankcase/block the filter would become clogged, and when this happened, strange things would occur..

     

    the clogged blow by, caused sooo much high pressure build up in the crankcase/block, the turbocharger oil drain would not even drain the oil, because the high pressure was keeping the oil in the line. This would result in the oil to leak out of the turbo seals, and drip into the exhuast, which would smoke really really really bad.

     

    I then ran it open with no filter or anything, but I feared on a dirty or wet condition, water would enter the crankcase and contaminate the oil.

     

    SOO.. I attached clear hose from Home Depot to the crankcase PCV outlet, and put the open end behind the brake master cylinder and brake heat shield so no dirt would enter it

     

     

    Well.. with the PCV and nasty blowby gases pointed at the firewall, and the old rubber grommets I had, when I rolled the window down the high pressure in the engine bay would flow into the cockpit/cabin and create a vacuum.. ****, now I am smelling all this nasty *** blow by...

     

    I decided to buy the largest PCV valve I could at Checker Auto Parts, and attached a 3/8" hose to the intake manifold... obviously since it's smoothed and cleaned up, I TEE'd off the blow off valve vacuum source, and voila!!

     

    Magic! I noticed the engine seems to run a weeee bit smoother, and the RPMS are steadier... (the vacuum creates a better seal between the pistons rings and crankcase)

     

    here are the pics

     

    Notice the tube from under the intake manifold to the crankcase hole, and the shiney silver filter?? well that didnt work

    well NOW here is my ghetto setup

    Reverse coolant flow for turbo engine

    in Turbo / Supercharger

    Posted

    umm..

     

    its not the coolant that is causing detonation

     

    yes the effectivness of the coolant reduces the chances of detonation.. but the key to preventing detonation is proper air/fuel ratio and timing..

     

     

    you can have pre-ignition of there is a hot spot ... or detonate with a poor mixture or high cylinder temps..

     

     

    an F54 block has better webbing for improved cooling.. buy an aluminum or 4 core radiator.. and a good electric fan and you wont have to worry about anything

     

    the Nissan engineer's have it the way it is for a reason..
