i havent done one on an rb motor but generally a little judicious use of a chisel, a stanley knife blade and a little tickle with some emery does the trick.

Forgot to mention the blue coating causes the cam gears to glaze over hence the belt slipping.

As Dale has already correctly stated, synchronous/timing belts don't slip, they are a positive drive system. You may be thinking of 'slip' when it is actually ratcheting teeth which means it is no longer synchronised (extremely bad for interference engines). A lack of tension is the only real way it can do this. The correct tension keeps the belt teeth in mesh with the sprocket grooves. Timing belts just don't stretch, they are manufactured not to.

well i got around to changing my timing belt today, bout 6 hours down so far, and still have to put 2/3 of it back together. this is tough for a first timer, but i'll be glad and better for the experience when it's done. big thanks to the guide that was posted previous, has been a big help, some bits had me confused where pieces of info weren't in their but i managed to figure it out, fingers crossed it runs good when i finish it tomorrow :unsure:

your right Dale ,horsepower doesn`t mean diderly shit, all comes down to the tension on the belt, pulley condition , tentioner alignment and age of the belt. I bought a couple of Japanese belts of Ebay,good quality and reasonably priced, cant see any reason to change the water pump because it was perfect. Guess it depends if you do your own work or pay someone to rip you off. did the whole job in under 2 hours, amazing how quiet it is now though. one thing to remember , not all belts have the same profile,hence the whyne? which means incorect fit and probable failure.

AHA! Hit the nail on the head for another reason of slippage or jumping teeth. I spent just over ten years in the automotive industry/engineering, & there are 3 "general" designs of tooth profile that manufacturers use. Miss match teeth & sprockets & whammo! Stick with OEM & a good parts interpreter (unlike a saturday nissan guy who ordered the wrong consol part & tried to sell me diesel oil for a Stagea & Cube!!!!), check your profiles before installation & you cant go wrong!

oh forgot to update, :unsure: all is well, timing is back where it was set, car runs perfect had a slip of aircon belt on initial start up to get rid of some excess water (splashed on belts when i forgot to put bottom radiator hose back on before filling, silly me in a hurry to get it finished) but yeah car is good as new and next time i need to do it should be alot quicker as i now have ALL tools required and know what needs to be removed and what doesn't. as i mentioned above kudos to having SK's tutorial to follow.

      Rear suspension upgrades

      By GTSBoy · Posted

      People like Johnny Dose Bro might be laughing at my post because I accidentally added 100mm to my numbers. 350-355 is indeed the lower limit. 450 is off-road Skyline spec.

      What is the "compromise" that you think will happen? Are you thinking that something will get damaged? The only things you have to be concerned about with spherical jointed suspension arms are; Arguments with the constabulary wrt their legality (they are likely to be illegal for road use without an engineering certificatation, and that may not be possible to obtain). A lot more NVH transmitted through to the passengers (which is hardly a concern for those with a preference for good handling, anyway). Greatly increased inspection and maintenance requirements (see above points, both).   It is extremely necessary to ask what car you are talking about. Your discussion on strut tops, for example, would be completely wrong for an R chassis, but be correct for an S chassis. R32s have specific problems that R33/4 do not have. Etc. I have hardened rubber bushes on upper rear control arms and traction rods. Adjustable length so as to be able to set both camber and bump steer. You cannot contemplate doing just the control arms and not the traction arms. And whatever bushing you have in one you should have in the other so that they have similar characteristics. Otherwise you can get increased oddness of behaviour as one bushing flexes and the other doesn't, changing the alignment between them. I have stock lower rear arms with urethane bushes. I may make changes here, these are are driven by the R32's geometry problems, so I won't discuss them here unless it proves necessary. I have spherical joints in the front caster rods. I have experienced absolutely no negatives and only positives from doing so. They are massively better than any other option. I have sphericals in the FUCAs, but this is driven largely by the (again) R32 specific problems with the motion of those arms. I just have to deal with the increased maintenance required. Given how much better the front end behaves with the sphericals in there.....I'd probably be tempted to go away from my preference (which is not to have sphericals on a road car, for 2 of the 3 reasons in the bulleted list above), just to gain those improvements. And so my preference for not using sphericals (in general) on a road car should be obvious. I use them judiciously, though, as required to solve particular problems.

      Misfire/stalling issues

      By joshuaho96 · Posted

      Easiest way to know is to break out the multimeter and measure it when cold, then measure all the resistances again once it gets hot enough to misfire. Both the original ignitor and the J Replace version. Factory service manual will have the spec for the terminal measurements.
