New valves, verdict

[hanby42]

I'm after some OE new valves and came across these on ebay

http://pages.ebay.com/link/?nav=item.view&id=120995424859

Just after opinions on them, obviously there a damn bit cheaper than getting them from Renault! Also, no I don't have the money for supertech ones before anyone starts ha ha

Buy cheap, buy twice.. or in the case of pattern part valves three or four times over from the damage they could cause if you have a failure.

 

[George182]

Get genuine ones IMO - not an area to be taking a chance on some cheaper ones to save a couple of quid!

 

[Mr R.]

Buy supertechs, although I have my old valves that came out of my head.

 

[hanby42]

So a no no then? Thiught if they were OE would be fine but guess I'll just bite the bullet!

 

[Mr R.]

Even the Renault valves are known to drop thats why ive gone supertech.

 

[hanby42]

Well I'm going with catcams springs and I've increased the valve clearance on the pistons by 1mm all round as well. I'm only running 428's so not massive lift.

 

[hanby42]

So apparently Renault don't sell valves anymore, none on the Renault parts direct website. Found some OE on the engine dynamics website though?

Still the same for these? Avoid or ok?

Where are the OE ones?

I only saw supertech and cheap aftermarket?

I would prefer to use 100K mile old secondhand standards than cheap aftermarket ones TBH

Why have you done that? Just lowered the compression for no added performance...

Also cat cam springs are needless on a standard engine with such mild cams.

I've seen no end of failures on aftermarket valves.

Also Renault Will supply new valves. They have to. EU Law states you must be able to buy any part for 10 years after production iirc.

 

[hanby42]

Because that's the reason the valve snapped, 4/8 of the inlet valves had been hitting the cylinders, and the amount of metal actually removed is negligible tbh.

Re the springs, OE springs from Renault are more expensive than the catcams ones so thought it would do no harm getting them.

I agree about the valves as well, would prefer to get ones that don't knack up so I don't have to do all this again but atm can't afford supertech with everything else atm.

I'll have to try ringing them and get a quote, if it's not far off supertech I may as well go for them. Iirc you got them direct from USA cheaper?

 

[Chip-mk1]

Yeah I buy mine from supertech direct, very cheap stateside but the problem is the postage is about 100 dollars so only really works out well for a few sets.

 

[Mr R.]

I have my old valves out of my 49k head if you want to buy them?

Better than some un-known crap.

Only removed as i have Supertechs.

 

[hanby42]

Don't suppose you've got a spare set kicking about then chip ha ha?

I'll PM ya phase1er

No the reason it snapped was through someone not being able to time it up properly.

I can supply supertech's at £360

 

[hanby42]

Hence the reason I'm doing it myself now!

Cheers Dan I'll get in touch if I need some!

[bozothenutter]

sinus valves said the parrot..

 

[hanby42]

Ha ha I wish. At the moment my main priority it to get it on the road. One day I might build a forced induction or high comp engine!

Also on the back of this, when re fitting the dephaser is there a particular way it needs to go on just I cant find anything about it in any of the mechanics guides or on here so I'm assuming it don't matter, although there is what looks like a guide on the outer?!

 

[Martin_172]

you lowered the compression to improve valve clearance because someone couldn't time it up properly? are you planning on timing it up wrong this time too I assume?

Still the same price, ive just bought a set from them.
