Theres plenty of people running over 500 in the us one running 800 on sock internals, and one chap running frint mounted tubs il dig.it.up later

Theres a thread with a vid of mine when I had issues.

I wouldnt say thats definatly it, uou still not even said what colour it is. Lots of variables as I said. But yes the top cam covers are baffled to stop that.

The front pcvs that vent from the top cam covers do very little drinking of oil, inside they're extensively baffled, that's why Nissan only put in a washer type restrictor. So id say that's unlikely that's your problem. If your experiencing grey smoke after periods of prolonged idle and it clears at over say 2500 rpm, its quite possibly your turbo exhaust seal :( is the car decatted by any chance?

There are lots of causes for oil burning in the zed, pcvs as you know, the car will also suck oil up on hard turns because of the pcv pickups location. you could also be pulling il up from the turbos, if the front seal has failed fully or partially, valve stems, oil rings etc etc etc. Process of elimation im afraid, what colour is the smoke? and when how does it occur? those two things will help greatly in diagnosis.

So valve stems were good? The gasket kit was at fault?

I would be suprised if zcenrre japspeed or 2fast2cool ones are different products, theyre so simular an suprisingly go in out of stock at the same times.

Great, thinking about it, if was a case of old ones the block would have smoked like a pig, so its probably a case of improper fitting.

Sadly you need a bloody good spanner or pref a crows foot, theyre quite big like 21mm cant remember, be prepared to heat them up to be able to remove

They may not have fitted them properly, so the stem seals popped out of place. Troubld is there so hidden in thhe head, not like an old ford pinto sohc or crossflow :( feel for you bud. Is it only on the number 6 exhaust valve? Both, one or more?

I wouldnt go stripping the heads down bud, give them a call before you go any further, they need to be shown its not been done. Then id be on the blower to citizens advice, you paid, you didnt receive thread carefully and they wont have a leg to stand on.

Zcentre or mjp I guess

I believe yh he pita bit is the piece from the the turbo front to the acordion pipe, because of the restriction, the stock ones are a damn funny shape.

it would be quicker to search.....

that clears that up lol, wealth of knowledge strikes again.

not to be a party pooper but if you put this into the search function you will get page sand pages. personally id go for uprated side mounts everytime unless I was running like 700bhp, I don't like the idea of pushing hot air over the rad, and the cost advantage goes out the window if your buying a front mount that's good enough quality to outperform the sidemounts available from z1 godspeed etc

Yeah ive heard they are doing mass production in china and that's were the quality has slipped, you would normally associate the with quality stuff but its definatly not cheap enough to warrant the issues. - - - Updated - - - yes yes lol you have all the toys I want lol

That looks seriously time consuming, do you use a purge line inside?

cheers bud :)

Lobster backing is very time consuming I remember doing my college project which was a series of lobster backs with a square to round each end, so I can sympathise with the time and attention involved. Theres a company locally to me called tube form technologies, literally all they do is bend tube, they used to do some bits for us when it wasn't so critical or we were overrun to cut on costs, I recon giving them a bell might be worth a shout as they have all the stuff to cut the production costs right down, obviously id need a complete oem set to copy to start with.

so I take it your cutting and welding sections to create the curves? triple rollor would be a lot quicker and easier, but obviously its and expensive bit of kit, mandrel bender would leave you with those annoying pinched parts, the kind you see on cheap exhaust systems.

I take your point over things like intercooler rads etc where the welding and internal structure and overall build quality is paramount, howere when were talking about pipe... theres nothing mysterious or hidden or complex just tube bent at angles. AMS make a very similar kit which people are moaning about because of fitment issues around the engine mount, that I would be annoyed about, hardly ebay crap.

I can see how as getting the bends is trial and error to.a certaok n extent(i used to make stainless handrails and sprial staircases) however once you know the settings and are producing volumes production costs falls drastically. The stock system is made from mild steel is it notm so I see no reason why its got to be made from expensive alloy.

Many of you may not be familiar with these but the apparent advantages are vast esp with bigger tubs. However my gripe as always is price! $700 is esp by the time they land here in the uk disgustingly expensive for some ali tube with some flanges welded on etc. once the settings are on the machine these are seriously easy to make and cheap, so that mark up must be horrendous. I think im going to have to start speaking to afew people about how much it would cost to have some made locally.. http://www.conceptzperformance.com/Cart/description.php?II=4894&Car_Type=300&UID=2013031311073482.10.116.65
