son what the **** are you posting about? if you get exhaust out the rear mufflers, your exhaust is connected to the turbos. ALL exhaust goes through the turbos in one way or another. screamer pipes?
Firstly , make an account with Photobucket so your pics stay uploaded . We still dont know exactly the spec of your motor . Is it turbo ? Looks like the exhaust has been cut just after the dump/header flange . Does the otherside look like this ? If you see smoke from exhaust , either the other side is still connected and smoke pours out of it or smoke is coming straight out of this cut pipe and underneath your car . I highly recommend you not drive far or your clutch line will burn and fail . My advice : Take more pics so we can see exactly whats going on with your car . Make freinds with someone that knows about mechanics or Z's or both and get him over there to check your car out . This is a disaster waiting to happen .
If you can see a turbo hanging in your engine bay then it has to be connected to the engine, or it wont be in there for long. as to whats been done to your exhaust then I dont have a clue as others have stated there are not enough pics of the right areas to tell. OK all. I did a little fact finding and here is the results >>>>> http://www.aus300zx.com/forum/showthread.php?t=317345 definately engine out time I would say and this is not the first time he has been told this. for the OP the advice on the engine work (and the other crap) still stands. I would suspect there is more than a blown head gasket for you to worry about. although you may be lucky and it may be a turbo gone. in the end you WILL need to pull the engine
Mines twin turbo yer. Both sides have these pipes that have bn cut. As far as I can tell my exhaust is connected. Before I did my head gasket it never smoked. And now that it is it only smokes out both exhaust. No smoke is coming out of these pipes under the engine. I'm going round to see where the machanic is at tonight. My turbos were connected and like I said it was still hitting its factory top speed. That anti bloke asked if the pipes are screamer pipes. What are they?
by the sounds of it they are probably your turbo oil drain pipes....dont hook them up and your turbos build huge boost and you will hit 280kmh
Turbo's generally have whats called wastegates, which open to bypass exhaust gas around the exhaust housing. Normal people have "dump pipes" which collect the gas from both wastegate and exhaust turbine before sending it through the exhaust and out the rear of the car. Screamer pipes instead seperate the gases from the wastegate and send them un-muffled, straight into the atmosphere, generally directly under the engine. They are fking loud, and scream once you hit boost...hence the name. The wastegate only opens when you have reached your controlled level of boost. When then this happens, the wastegate opens/closes to maintain the correct velocity of exhaust gases through the turbine, and maintans boost. The primary exhaust from the turbo's still flow through the system as per usual. Turbo seal failure is a common cause of smoking, although, not generally a cause of loss of power, not significantly anyhow. Head gasket is an engine out job unless your awesome and know these engines and engine bay back to front, and if you do, you know that it's a b!tch of a job and you will pull the engine anyhow. 3rd smokey reason is piston rings/ring lands which equal a flat out rebuild 4th smokey reason is valve stem seals, which is unlikely due to the circumstances of it occuring during a flogging. All of these smokey reasons are a labour intensive and engine out job, no way around it. That in triple enforced by the fact that there is bags load of work to do to that motor as it's never been maintained in its life. Your first point of call is to find out why its smoking, find a mechanic and ask them to do a carbon test on your coolant to rule out HG Pull off your exhaust from the turbo's and look for oil = exhaust seal Pull off your intakes to look for oil = intake seal Do a compression test = piston rings/lands Maybe do a leak down test for valve stem seals No easy way out of this one. Kinda like asking questions about a oil relief valve when you have a hole in the side of the block from a snapped conrod.
Must be screamer pipes. When I give it full nose it almost sounds like a supercharger. I really wish I'd found this forum before I'd bought my zx. But I do love it
you guys are pretty harsh on him, even though he sounds like a noob, Id say something has failed and gone up the intake, like oil, metal bits etc now he needs compression test,and it is possible to do one head, in place just time consuming and a PITA
Boys I can't help living in the sticks. Unless it's got a Holden or a ford badge on it it might as well be a UFO. People talk to me about my car and for some reason it's a 4 cylinder skyline. The most common car where I live is a dumped commardor. I don't pretend to be a gear head.
so were do you live? you should take photos/video of your problems and post them on here. If you have no base kowledge to work with i suggest you start reading up on the problems you think it could be and how they are diagnosed and resolved. educate yourself and looking under the bonnet wont give you a migrane.
How was my post harsh? I answered all his questions and went through the scenarios...I thought it was the most constructive one of the lot.
Im from a small town bout half hour south of the nsw border. I posted a YouTube video that looks and sounds like mine that's why I think it's a head gasket. As I said no one round here has something like mine. I'm trying to llearn about my my car, that's why I'm here.
Don't be hatin' on Hiluxes now. It takes more balls than you'll ever have to hold a Hilux on speed limiter with nothing but a sheet of aluminium holding the rear wheels on the ground.
From what you've said so far, its clear that you wont be able to remove/replace the engine yourself, if its necessary, let alone diagnose and repair it properly, and the local mac's (for reasons unknown) think its a ufo, when the reality is, its just a V6 with turbos. Your options are limited, but you still have some, one would be take to a known zed specialist here in vic,(expensive $90+p/h, no parts supplied) I don't recommend this until you have found out exactly whats wrong with it, going to one of these shops with no knowledge at all is very a dangerous business. If your problem turns out to be a blown head gasket, surely the local mac can handle that, if not, he shouldn't be in business.
