I was wondering if the timing belt cover (near the top of the engine) can come off to expose the cam gears or is it a one piece cover that goes all the way down ??

I want to take the cover off so I can better inspect where I'm getting noise from on cold starts ... anything that I should be aware of ? in regards to cover ? or cas ? how do I make sure the cas goes back in exact same position when I've take the cover off? cheers

r33 has 2 piece cover not sure with yours. to get the cas back in the exact spot you will have to reset timing when your done. think the tensioner pully may be hidden by the lower cover but not sure. this is the car with ticking noises yeah? wasnt lifters? changing to different oil didnt stop it?

yeah ... I'm almost certain the noise is just the idler bearing and its been gettin louder so I'm worried it might snap soon ... I've seen 3 youtube vids (2 of them from sau members) with the EXACT same noise from same area, that went away completely after they changed their idler bearings. So i'm hoping that's the problem with mine too.

Only weird thing is .. when i listen to the noise using a stathoscope I get the most noise from the cas bolts ie. just behind the (exhaust?) cam near the top of the engine and the idler bearing sits a bit lower than that (I think) but obviously I can't get to the idler bearing area to listen to because of the plastic cover

Without a timing light you could use a permanent texta and just outline the screws on the CAS, putting back on should be as simple as using those lining marks.

It could be the CAS itself making the noise too, when taken off the stalk should freely spin with no resistance, if there is resistance then it's dying (if it's a mitsubishi type Ive been told they are repairable).

i used a screw driver to scratch a mark for the cas. unbolt cas, unbolt cover and you should be able to slide it up without taking the fan and shroud off. if your going to run the motor without the cover on to find your noise, make sure you use some sort of packer/washer the same thickness of the timing cover between the cas and its bracket. and for testing with the cover off the cas doesnt have to be in the perfect spot, just set it as close as you can to where it was before and it should run fine

    • how do you know voltage is fine?  quick easy test is connect DMM up and put it on max/min mode, remove fuel pump fuse, crank car for 3-5s, go check min voltage You'd be surprised how many "healthy" batteries are showing under 10v during this test in cold weather. 
    • Not properly. You need to be able to dissipate 100 amps or so to doing it meaningfully. You can do it indirectly by watching to see how far the voltage falls during cranking. Unplug the coils or something else to prevent it from starting so you can get a good couple or three chugs. It also helps if you have the multimeter set up reading before you start, and that it has max/min functions. So you can catch the real minimum without having to watch the screen, which often doesn't update fast enough to show the real max/min in dynamic situations. Or use a digital oscilloscope, which can be obtained for <<$100 from Aliexpress (although I'd argue for paying up to ~$200 for a nicer one). A >4 yr old battery will very likely be well down the path to the knackery. Many only last 5-6 years these days. The cold weather lately will definitely make it worse.
    • Hmmm, what do you mean by getting weaker? And where did you get that test done? I've been wondering about my battery because the cold starts crank super slowly. The voltage is fine. Not sure if cranking amps can be checked at home. Battery is 4+ years old.
    • No. The simplest wastegate hookup, with no solenoid or other form of "boost control" (ie, control over your boost control, if you know what I mean) is a single hose, direct from the turbo outlet/hot pipe, straight and only to the wastegate actuator. It is that pressure signal that drives the wastegate to open, providing the boost control (and by "boost control" here, I mean, limiting how high it can go, which is essentially the spring pressure of the actuator). You only end up with tee pieces and alternate flow paths once you start adding things to the boost control system to allow you to determine how much of that boost signal makes it to the actuator. There are so many ways to do that that there is no single way to run the hoses and tees and the like. If you have a stock boost solenoid, then all it does is either allow all the boost signal to go to the actuator, or open up to allow some of it to bleed off. There needs to be a restriction in that bleeder to allow only a small amount to bleed off. And in a stock system, that would then be plumbed back to the turbo inlet (for "emissions control" reasons). That is actually what that nipple on your BOV return pipe could/would be for. If you have an aftermarket boost controller and solenoid, then the above is mostly true, but there is no need for a restrictor in the bleed, because the solenoid is pulse width modulated to create a variable bleed off. The air that escapes from the bleed can either be vented, or also returned to the turbo inlet. For emissions reasons it should be returned to inlet, but the amount of air being vented is so small that it really doesn't matter (either from an emissions perspective, or from an air-fuel ratio affecting perspective).
