Can you remove the dephaser.....

[Jonny1*2]

...... and replace it with a fixed pully? anyone done this? It would obviously remove the vvt, but can it be done so long as the diametre and number of teeth correspond to the original size? Just curious as it costs a lot for the pully and the fact that they seem to be quite fragile (mines now fubard ). I assume so long as the cam angle is fixed in the correct position it should be ok ie. the second phase or the dephaser?

I only know of one person to do this and he filled the oil galeries with weld then had the end milled down so the inlet cam was the same length as the exhaust cam. TBH if your going to have to strip it that far you could buy a set off catcams VVT delete cams. Then maybe drop a set of vernier pulleys on as well.

They tend to wear once in every 100 thousand miles. Thats not exatly a fragile part. They dont even break anyway.

Folk worry like mad over this part

Which CATCAMs are these mate? number? What pully would it need replacing with? Meg one?

Mine is fubard mate. Had the belts done and within 20 miles it was horrendous. He checked it for movement before replacing the belts and it seemed fine. Plus the cost it is to replace seems an unneccessary risk really. Freds pile of dephasers might disaggree with the 100,000 mile theory also.

If you have a look on ktecs website all catcams are available with the vvt delete option there also down to £580 at the moment. You'd like to think they would be cheaper due to not needing the oil galleries machining in. Pulley wise just use an exhaust pulley or as mentioned stick a set of vernier pulleys on there.

It is possible on stock cams, its been done before with an exhaust pulley and a couple of other bits, along with blocking up the oil feed from the solenoid. I looked into it, even back to some posts on here from 2003/2004, and from speaking to Matt@TDF - BUT, timing them up is the only issue, there are tools out there to set the timing with a very posh 'horseshoe' tool, which allows you to set the cam angle before tightening the cam pullies up (CatCam make a tool, as do a few others, talking a few hundred quid though) as you'd need to set the inlet cam 16degrees advanced, or it would make sh*te power. Verniers are another option, but most only allow adjustments of 12 degrees each way don't they? Which would mean you'd get nowhere near stock timing (when on VVT) by setting it using Renault tools, you'd still need the specialist setting tool...

Yeah but they dont ''fail'' as in risk of totalling the engine and iirc its not even a Renault service scheduled item.

Pretty sure you wont find play in the pulley either. A expert on here reported he's fixed a few by only oiling it.


I was told ditching the VVT would make the car run like a bag of sh*t on a road car and only really advisable on a track car

keeping VVT control gives you fairly noticable benefits. Switching vvt back off at the right point in the upper rev range can make a big difference to torque and bhp

I think you're approaching the issue with a little too much paranoia in honesty, not helped by a fair amount of scare-mongering that's gone on on this forum recently. If your pulley is knackered then just get a new one and do your oil changes more regularly. On the rare occasions i've seen dephasers become noisy the engine is invariably filthy inside

Sounds like it could be a pain tbh. I'm just thinking if i'm going to be plowing a few hundred into the dephaser I could spend elseware. I was a bit curious of how to adjust the cam angle jord. Sucks that it would cost so much to do. I would imagine that it would require mapping to sort the low down fueling out also?

I'm not paranoid about it Danny, if I was I would have got it changed when the belts were done a few weeks back and saved all this hastle . It sounds loud as hell now. You can here the cams rattling away. Don't really want to damage anything internally. Granted it's highly unlikely, but if it prevents another bill then it's probably not a bad idea. I do change the oil regularily though. It's either to do with the fact the car was stood for 4 months post trackday, or there is an oil pressure issue somewhere and oils not being circulated. The oil in it was brand new the night before the track day I did prior to the electrical problems.

It's so annoying. Had the car for 4 years now and it never skipped a beat. Since the electrical issues, there have been a few problems. Never leave an RS standing

Mine went noisey on my old titanium, I aint sure what the garage did, but it was only there for a couple of hours, and he only charged me for a oil and filter change, he said something about the oil being too thick???

 

[BoomOne]

Because you did not change your oil enough ^^

 

[dicko]

mine is also noisy grrrr im gonna try oil flush and new oil and filter first before buying new one

 

[jenic]

Just change it for another imo.

Whats the chances you'd keep the car/engine long enough for it to go again?

 

[Jonny1*2]

fare point mike. Mine wasn't just noisy when i took it in. You couldn't hear the normal engine noise or zorst it was rattling that much. Propper fcuked
