Guest MaXbOOst Posted August 29, 2004 Share Posted August 29, 2004 ok so i swapped my n/a for this turbo motor , i re-did every wire in the car lol.....went to a junkyard got ALL harnesses and swapped them into my Z ( so i didnt have to splice wires ) and everything works YAY ! motor wont fire up though. i ran my crankcase vent line to my valve cover breather like i seen one guy with a Z do. my last Z woulnt start anytime i pinched the valve cover line......... so im thinking , if i hook the crankcase vent line right up to the pvc valve , and the valve cover line up to the intake hose she should start right up , beacuse i can crank her over , hear the cylinders fire , the exhaust come out , but im definite its that. even when im holding the pedal all the way down she wont start....... so if i hook up the crankcase vent line to the pvc , and the valve cover hose to the intake hose she should fix this right? heres a pic of how i have the line setup Quote Link to comment Share on other sites More sharing options...
Guest bastaad525 Posted August 30, 2004 Share Posted August 30, 2004 OMG who the heck had their Z set up like that??? That's the same thing as just blocking off your crankcase and valve cover vents... you do NOT want to do that, especially on a turbo motor! While I doubt that would in any way cause your car not to be able to start I suppose it is possible, but I would bet against it. What it WILL cause, is for large amounts of blowby pressure to build up in your block, especially whenever you're on boost, which will start failing your gaskets and oil seals and give you a very leaky engine in short order. With the hose hooked up like that the blowby has nowhere to go. You will also end up dirtying your oil much faster for this reason. Either hook up your PCV system fully the way it was stock (crankcase vent to PCV valve on intake, valve cover vent to ... well I forget where it goes, but somewhere on the intake tract but before the turbo if I"m not mistaken, somewhere where it will NEVER be pressurized by boost). If you run it this way, it's not a bad idea to get a NON-vented catch can and run your lines thru it to keep oily buildup from getting into your intake... kinda complicated and expensive. The other problem with this is that any other leaks in your engine, say, a not perfectly sealed oil dipstick, will allow unmetered air in and cause a vacuum leak. Or you can run breather filters on both vents and just leave them open to atmosphere. Easy, cheap, and not very clean. OR the best, cleanest, and least complicated method you can do (and with that nice new looking engine, I personally would do) would be to get a VENTED, open catch can (has a little K&N filter on top) and run a hose from both crankcase and valve cover vents into that. This way both vents will dump their oil into the catch can instead of all over your engine, but they will still be open to atmosphere and any blowby pressure will be able to escape freely. You also don't need to worry about vacuum leaks from your dipstick or anywhere else. Whatever you do, do NOT drive your car the way it is set up now or you may very likely regret it as you'll be replacing your pan gasket and main seals. Again, I doubt this is what's causing it not to start, but it's possible. About the not starting, have you checked that you're getting both spark and fuel? Check for spark from the coil and at all plug wires, for fuel, the best way would be to pull the injectors and be sure they're spraying. You can also pull the spark plugs after cranking it for a bit, see if they smell of fuel or are wet. Be sure you're fuel pump is coming on, check for pressure in the fuel line with the key in the on position. If you don't get wet spark plugs or fuel smell, you may need to check the injectors another way, either listen to them with a 'stethoscope' and see if they're clicking, or pulling them out but leaving them connected and letting them spray into some open container while you crank the motor.
