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:

Let us all know how it went jeremy??? :)

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.

    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.  
    • For race cars, this is one part where I find having the roll cage bar having gone through a hole in the floor better than the build it up on a ledge inside... The Merc I help on, the main hoop ends are marked on the car, and the jack is marked... Jack goes under a few inches and lifts one whole side of the car up... Removes that fight for long slim jacks for race car duties!   My biggest issue for the daily drivers I work on, is my jacks don't go high enough. The jacks start out on a few blocks, jack it up, then start a second jack under it on more blocks, and then I can get an axle stand under it. My axle stands are presently in use, and are nearly fully extended. The car is sitting with barely more than a cm of clearance to get the wheel off the studs! Sarah's Kluger is the same, as it has an ungodly amount of droop available in the suspension and a distinct lack of good jacking points!
    • Happy? Yep, my to do list is getting shorter and shorter. Either this light approaching is the end of the tunnel, or I'm about to be hit by a train... Ha ha ha   Also, Duncan isn't that far out of town that you need to make a multi day drive out of it. 😛
