Hey guys just wanted to ask some advice. I park my car on a slight incline, so that the front is higher than the back of the car. Every time I start it in the morning, after a few seconds, there's a horrible screeching sound coming from the engine, then the screech stops, and the revs increase a little then settle down after about a second to the normal rev range for idle. I'm not quite sure what this was, i thought it was low power steering fluid or something so I topped that up, but now that that's ok I'm not sure, because if I drive off too soon, the moving off process causes some slight screeches too...thanks in advance :huh:

Sounds like a belt is a bit loose and when it sits it slides toward the back of the car and rubs up against something. Which belt is the scary part! Could be simple, A/C, Power steering or Alternator... or SCARY, Timing belt.

Get a Mechanic to check asap, or look yourself... but I'd say from what you've said you wouldn't know if the belt was too loose or too tight. So go the Mech :huh:

i'd say its just a belt slipping. and what is happeneing is that it is spinning for a second, then it heats up a bit and gets sticky and grips and gets on its merry way. very common problem amoung any type of car.

just go round and tighten all 3 belts slightly.

i hear that screaching noise every few months , i mainly notice it when we get some rain or a misty night , my opinion is it could be moisture getting to the belts? my opinion - im not a mechanic or anything , but i do notice it in those conditions . on my old car i got the same noise and sprayed some wd40 on them , would stop the noise , from happening in winter

Just a quick question (may be dumb lol) but how would i go about "tightening" the belts, i thought when they got worn out and started slipping you just had to replace them, can you extend the life of them?? Thanks heaps :(

Regards,

I'd replace them, but I'm picky :)

First you'll need to identify which belt is lose, they all have a little bit of slack... but you'll notice if one has more then the others.

Then find the tensioner/pulley that is on a sliding hole (when you loosen the bolt it can slide along that hole). Then just slide it until it's reasonably tight. It's not a big deal, but just remember to be careful and don't make it too tight as to stretch/damage the belt.

Wet some soap untill it becomes like Jelly then apply to the belt.

PRESTO......no noise.

That may stop the noise, but wouldn't it encourage more slipping?

Soap acts as a lubricant, especially when moisture is added.

If you want to be that dodgy, you'd be better off pouring coke on the belts.

When the soap dries it ends up being a dry lube.

Coke :spank: .....is only when u use Bourban......

Dodgy you say.....my mechanic recommended it.

Angry Fist.........Post up your results after you have lathered up. :sick:

The thing is you dont want to lubricate anything here. Belts arent supposed to slip.

Another cause for a slipping belt if its not just slack is it can be bottoming out in the pulley. Like i said b4 check for correct belt tension and signs of slip and replace or tighten as necessary

I recently had a loose fan belt that made the same noise until the alternator regulated output to 14V, then it would stop.

Tightened a smidge and it's good as gold. 5mm just like Deren suggested.

PS Using the soap is a good way to help identify which belt is causing the noise. Washing up liquid works ok as well. It saves replacing belts left right and centre.

Tighten it up, or as someone sujested soap as a quick fix to the annoying squeek.

I'd sujest dr y soap, just take a cake of the old "sunlight" yellow shit, and why yoru cars running put it on teh belt :) I did it when mym was winging about her commodore squeeking, and becuase i coudlnt' give two f**ks about that car i soaped it up :) when i took my alternator of for re-conditioning i didn't do it up tight enough so mine did the same, but i stayed away from teh skyline with the sunlight soap, i just tightened it up :)

Same happened to me yesterday - put your hand on the pullys of the ALt and Steering pump etc when MOTOR OFF and you will soon feel which pully is slipping from the temp, near burnt my hand on Alt pully. Sure enough belt a bit loose but not imeadiately obvious.

I loosened it right off first to check it was not the bearings though, then tiightened up.

      Took the car out to see if it still starts, sure does. Daughter wanted to for a spin too, she loves it when it doses, also cries when we come home and try to take her out of the baby seat 🥲  I actually put the seat in for her brother, but he absolutely hates the shitbox. Anyhow, so after looking at real boats, and transoms, bait tanks etc. and scupper valves attached to them, I came up with ideas to improve the catch can. The primary goal was to stop the interior smelling like vented catch can shit when the windows are down OR when the HVAC is not recirculated. My catch can has a sump drain/feed at the bottom, 2x cam cover inlets, 1x outlet back to the intake pipe and 1x vent at the top. The initial theory was at idle, and off boost there would be just enough suction from the intake pipe (pre turbo) to pull back any smelly shit from the catch can before it could escape out of the vent (which does have 1x layer of foam and a fine mesh screen on top). It kind of works, however on hot days, the motor is breathing more than the suction provided from the intake pipe (pre turbo) and there's a bit of vapours escaping (not a bit amount, but enough to piss me off). I could have just sealed off the vent, however it would mean each time I take it to the track or decide to drive it with a bit of enthusiasm, I would need to remove the seal. To address this, using scupper valve idea, I used a 3mm sheet of rubber and cut essentially a valve that requires a bit of pressure to crack open and vent. Took the shit box for a drive today, came back and parked the car. No heavy stench, great success ☺️ I still would swap for a F80 LCI or W204 2012+ C63 AMG, if anyone is keen 😅

      [Fuel pump] Is upgraded bulk head connectors or relay mod needed for fuel pump upgrade?

      By soviet_merlin · Posted

      I'm with Kinkstaah on this one. Do it once, do it right. So much better for your mental health. The sneaky thing about the fuel pump wiring is that it will work perfectly fine for the longest time. Until that one moment when it decides to shit the bed. And it's not worth the paranoia from not trusting the car anymore. At least other mechanical issues announce themselves by developing some noise or other warning. If you have the funds, I'd suggest to go with a good kit like Frenchys and get the work done by a trustworthy shop. No regrets there. The only downside to the Frenchys kit on the Stagea/R32 GTR is that their fuel level sender is not on point. But looks like the R33 kit maintains the factory sender so should not be an issue. This is what the botched setup on my Stagea looked like before it stopped working. It had melted its way quite a distance down. Glad it didn't burn down the car.   Some links I came across when I looked for solutions: Radium sells a DIY wiring kit that looks promising. I didn't buy it though, I let my workshop decide on wiring. https://www.prospeedracing.com.au/products/radium-diy-fuel-pump-hard-wiring-kit-17-0031 https://www.radiumauto.com/DIY-Fuel-Pump-Wiring-Kit-P368.aspx   You can also get cheap replacements for the locking ring depending on how mangled it looks: https://www.kudosmotorsports.com/Nissan-17343-79900-Fuel-Tank-Outlet-Locking-Ring-for-Nissan-S14-S15-BNR32-R33-R34-AWC34 There are tools for unscrewing it as well so you don't have to abuse it with a screwdriver and mallet. The Frenchys one is expensive but I'm sure there are cheaper ones.
