m4xwellmurd3r Posted April 11, 2009 Share Posted April 11, 2009 alright, I need some SERIOUS help now. I fired up the Z today, and got a WONDERFUL metal hitting metal sound. the DAMPER looks like it's not straight and is tapping the timing plate from the looks of it. no unusual engine noise but I'm ALSO low on oil. AND pushing in the clutch moves the crank enough for the noise to lessen! the clutch still grabs like normal, so I don't think the rear main tore (I've had that happen on a bug, it wasn't a major tear, but the slightest bit of oil made the clutch turn to crap) and I think the oil thing is normal and I just never noticed. it does love to burn oil when it's cold.

ckolander Posted April 11, 2009 Share Posted April 11, 2009 My Z was doing this same thing last year, turned out that I needed a new harmonic balancer. Still do for that matter. Quote Link to comment Share on other sites More sharing options...
m4xwellmurd3r Posted April 12, 2009 Author Share Posted April 12, 2009 welp, I bought a new harmonic balancer, it's the SFI spec racing balancer MSA sells. I figure it SHOULD hold out till the new one comes in as long as I baby my Z. I think I should do a rebuild as well on my Z sometime this year, so I'm going to start piecing together a rebuild kit. (I could use a fresh N47 head if anyone has one...mines been milled and I don't think it was shimmed, nor do I know how to find out how much it's been milled) Quote Link to comment Share on other sites More sharing options...
jknc90 Posted April 12, 2009 Share Posted April 12, 2009 I've got an N47 (unless you're talking about the maxima N47, mines from a Z). Quote Link to comment Share on other sites More sharing options...
m4xwellmurd3r Posted April 13, 2009 Author Share Posted April 13, 2009 a Z N47. I want to see if it's possible to measure the head and figure out how much was milled, but I doubt that's possible. my engine USED to pull all the way to 6k no problem but it could be that my umm...unusual fix I did was the reason why. the FPR was siezed so the injectors were fed 100psi, so I just tightened the AFM spring till it ran good. that can wait for a while though. for now I'm happy with my halfway decent engine that does 20+mpg highway Quote Link to comment Share on other sites More sharing options...
