10valves or 16valves

[bill]

cambelt snapped 10 of the valves are knackered,was gonna just replace 10,but a mate says i should replace all 16 as the other 6 will be worn,engines done 78,000miles,getting fixed this week,what should i do???

any ideas how much valves are each???

not cheap mate. think they come in sets of 4 from renault for the 100 quid mark. not 100% on that though.

Inlet and exhaust valves are normally sold in sets so im not sure if you can get just 1. I would change them all seeing as its all stripped and most of them are bent anyway.

i think it sets of 4 or 8 depending on the engine. not 100% sure on that though.

£100 for 4 -bargain-not,think i will change the lot,cheers

id be tempted to buy a cheap 2nd hand head mate and get it worked on at the same time if you can afford to do it.

 

[Illusion]

If u can afford it, get them all replaced. Then again, I had no choice cos all mine were bent

Speak to Andy at GDI he might be able to sort ya out.

Your lookin at 65-70 quid per 8 valves.

The exhaust valves are a little bit more than the inlet ones.

thing is my mates doing the work,hes took the head off and sent it off to a garage,then hes refitting it all,so that bit wont cost me anything

 

[JAY172]

the thing is if its bent 10 then it probably knicked the others which might not be easy to visibly tell but when the engines back together and running could cause a bit of compression loss. I would personally change all the valves then you know the jobs done right then.

 

[Andy GDI]

Inlet valves £128 inc vat

Exhaust valves £137 inc vat

that is for williams ones, they are a little more than Valver ones.



Make sure they are lapped in propperally and all the cam covers etc are all sealed up with good quality sealant...



good time to change the cams as well while your at it....

65-70 quid,not bad,i can live with that,does gdi do work on the 16v,i was under the impression he was a 5 turbo man/transplants going off what i have read on here?

 

[bill]

ahh,andy gdi himself,already got piper cams in,dont want to spend more modding this engine just want to get it back on the road,as its either gonna get bb turbod or a 5 turbo transplant,cant decide?got any opinions yourself on that?

cheers everyone
