Ok i need a bit of help here, just changed my timing, fan, powersteering, ac belts.

I made sure all the timing markers etc all match up but after starting the car, it wont idle, just stalls everytime you take your foot off the accelerater.

Does this sound like i need to get the timing readjusted or something else??

Did you plug the sensor back in???

Also check your AFM plug if you disconnected that

Firstly yes everything that was disconnected has been reconnected correctly.

All the timing markers on the pulleys all match up with the correct markings on the belts.

I sorted out the stalling issue by adjusting the idle up slighty, but the car still feels very underpowered, any ideas????

check the timing , did you mark the position of the cas before removal ? did you put it back at the same pos ? my guess is your timing is a little retarded thats why you had to up the idle . so check timing with a timing light , about 15 deg .

Yeah i marked the cas and put it back on the same mark, im taking it into a workshop 2morrow to get the timing checked.

dont forget that a couple of mm out it will be a few degrees and thats enough to make it slugish , provided you did everything right and didnt bend any valves , if you did it would be missing though so you should be able to tell .

when you check the timing you will find

out , hopefully she will be ok .

scuzzy , yes thats right if on top dead centre but carefull you can bend valves if you let it jump hard and hit top of piston .

when you have the timing belt off you shouldnt move the crank or cams until belt is back in place .

so when I pull the belt off will the cams move off top dead centre on their own

no but if you bump them they will move like 90 degrees just like they sprung , like you said they did . what i said was be carefull not to let them jump like that cause you may bend valves ( you are moving the valves and not the pistons ) if they hit the top of the pistons .

if you are replacing the timing belt make sure you know what you are doing , incorrect timing can stuff your engine as will incorrect tension , even the bolts that hold the tensioner and iddler pullies must be tensioned right . do them to tight and you break the bolts not tight enough and they come undone .

if you havent got a manual do a search in these forums and you will find how to do timing belt .

Got the car back this afternoon, and the timing belt was out by just one tooth on the exhaust cam side. DAMN it made such a big difference to way the car would drive. All fixed now though.

how did you manage to put it in one tooth out when the belt has lines marked on it and each line has to match the mark on each pulley .

Good question :wassup:

Guess i just rushed it abit, i was sure i had it all lined up but i was wrong.

But doesn't matter now, i can enjoy driving the car again.

      Rusty roof repair

      By Duncan · Posted

      Shit thing to find eh? I guess the big issue is that whatever "fix" you do now, it might slow the rust down but won't fix it. I just wanted to add that in no way is fixing sheet metal in 3 dimensions the place to start with welding....that is a pro only job because its too hard to work out where things should be, let alone doing a clean enough job that it can look OK and still be strong too.  I needed to get a new rear quarter panel on the GTR and it took a pro weeks to get the old one off cleanly, new one on in the right place and looking somewhat like it should have with most of the previous connecting panels in place. Gluing a couple of bits of metal together with a welder in the garage is doable, but that is totally different to doing panel  replacement

      first time swapping rb25det into r34

      By Duncan · Posted

      This seems to be a very popular swap since all the turbo skyline prices went through the roof! I'll let someone more familiar chime in, but I understand that yes you probably want to swap the loom in to swap out the auto TCM stuff. You should not assume everything just plugs in either, you need to check at least the ECU wiring diagram for any differences at the plug at the left headlight and probably the ones near the ECU that join the dash loom too

      first time swapping rb25det into r34

      By dingleberry · Posted

      hows it fellas, my first post here which seems crazy cos half the forums i read are like the same age as me haha. to make a long story short ive got an r34 sedan (rb25de neo auto) which im swapping to a s0/s1? rb25det, r33 big box and nismo gt pro lsd. i have the motor and gearbox all bolted up outside the car, old motor and trans out. i bought the motor with stock ecu and loom, do i switch over to that? or will it be easier to get a r34 manual ecu and keep the loom if thats even possible.  also engine mounts look different, anything else thats different or incompatible? cheers, hope this all makes sense Paddy

      SAUNSW - World Time Attack Challenge - 5 & 6 September

      By Keeper · Posted

      Plan on the day will be to park trackside. Depending on space availability we will try put a small shade tent and a few of the cars on top of the hill inside turn 3, this is an easy to get to parking area with views of Turn 2, Turn 3, Turn 4 and Turn 5 and limited other pieces of the view around the track. IMPORTANT NOTE! One consideration from previous years is from memory the trackside parking sells out before the admission tickets, for that reason I encourage anyone planning on coming to buy tickets for parking now via the official website; https://www.worldtimeattack.com/ The type of parking you are looking for is 2 Day Park & View (Access Around Venue) Vehicle Pass Only Please note this does not include admission to the event itself, remember to grab that also, and kids under 12 get in for free!
