This is like the search for the holy grail

Fair point ,agree lets see what comes back.

I would say not Ian,if its a vacuum switch then i would say its not a suitable replacement and for a braking circuit slightly dangeroosey.

Also check your waste gate is returning ,mine had semi seized in the pivot bearing causing to spike just as you have described.....just before the turbo oversped and failed spectacularly (as was the accompanying bill)

And he wants £39k.....................

I agree 2 threads sounds very unsatisfactory ,what about an adapter to extend the threaded portion into the assembly and in to the accumulator a female to male type thing?

I have a Larini as well, and mine to split at the exact same bracket.I got to be honest i don't really think they are of the best quality,but they do sound great .I also had the decat pipe and all the hasstle that went with MOTs etc so i cut the decat pipe in half and fitted a high flow cat, and can honestly say that i noticed no difference in performance .

In that case i'd be hot footing down there its very well priced ,i wonder if someone on here knows this car ?? Have you done a HPI check on it ? Garage sale means(happy to be corrected though) garage warranty, but sounds as though the brunt of the things that do go wrong on the S4s has been addressed ....but it does seem a tadge on the cheap side ,but hey who am i ? SJ and South West are in the area(relatively) so maybe they could throw some light on it they may even know the car? Let us know how you get on they are great machines, very very good when behaving but very very bad when their not. ETA. Mines a similar age and the tanks are still sound,manifolds been changed as has clutch ,steering rack,gearbox rebuild(twice),numerous turbos,relays,fuel pump,engine mount,oil cooler rad,starter,alternator etc etc

Seems on the face of it a bit of a steal. MOT history is intresting ,only 200 odd miles between MOT's for one year.

I cant find anything for a 1995 S4s ,year ends at 1992 and starts again at 1996 on drop down menu ,unless of course they have nothing available ? just seems like a large chunk of cars to missed out on.

I've watched it several times and am very offended.............by the lack of Lotus content............probably

Can you read any error codes off the abs ecu? Sounds as if its commanding one side to release,also (stupid question) but you have checked all the speed sensors are good/wiring etc?

When you say gushing out ,where exactly is the fluid coming out of ? You do have the correct coolant tank cap ?

That does look really nice and finished .

Looks like you may have found your culprit...................now for the test drive !

It does sound like a waste gate issue one way or another,be it mechanical or vacum or a signalling problem,do you always get a positive throttle response or do you some times feel the car is a little 'flat' but the next time you stab the throttle all seems good ?

Hi Ian ,well my issue first started to manifest as an over boost issue which for me was down to a stuck wastegate pivot,but as you say yours has only covered a 1000 miles maybe yours is unconnected to my issue.When you say the car is in 4th 5th etc and the boost gauge climbs does the car actually feel like its gaining boost? or could it be a dodgy boost gauge transducer ,or as mine was in a poor state due to the wiring to the transducer being damaged.To answer your question my symptoms weren't exactly the same but i was just trying to think outside the box as it were, you can easily check the pivot by putting an open ended spanner on the crank it should move back and forward freely (i wish i had done this when my problem started and saved myself a few quid) Interested to hear how you get on. Just for info when mine first started to play up the car went like a rocket!

As mine had sheared one side and i was in the middle of now where, i just levered the remaining side off as the bolts were so badly rusted the remaining side sheared off with minimal effort/damage.I then had the support 'towers' repaired where the fibre glass had broken,resprayed and drilled out the remaining bolt shanks and rethreaded the attachments inside the bumper.If your attachments inside the bumper are shot then its a bumper off job i'm afraid accompanied by much hilarity and fun. Eta.Simon I gained access to the bolts through the diffuser.

Check that the wastegate pivot can move freely ,mine was doing this, and eventually stuck and caused a massive turbo fail,mine elongated the pivot bearing surface so eventually 'mechanically' locked itself.

Thanks for the info i look forward to seeing the results.

Hi Dave, It would be interesting to see a direct comparison between the stock manifold and the Alunox one ,also how did they achieve regulating the pressure of the day ? or was this worked out by calculations ? Regards Nick

Cheers one and all i'll look in to it and report back.

Hi Alan, A few years ago i attempted to replace my tail/brake light filament with a LED replacement,they fitted fine and worked reasonably ok if a little dim,the trouble i had was that when the lights were switched on and i was moving the abs tell tail light would come on.My take was that the abs computer sensed via the led that the light was on and therefore the car should be slowing and obviously it wasn't and faulted the system,it did take me a little while to sort that out and in the end i just replaced the led with the oe part.My question is are there better leds now that can some how work around the abs computer? Cheers Nick

Alan, Is that a reversing camera screen below your Hi Vac controls? If it is (sorry if previously discussed) what's the details of it?

OK I hang my head in shame and stand corrected.Out of interest what modifications were done to the engine ?
