Well TBH mate, rather than do it myself, i was seriously considering letting someone else do it and let them fit the hydro wand and line lock at the same time.

Im just worried about it bankrupting me, which is why i do stuff myself normally, but this is just a nightmare now

Give me a ring tomorrow i will sort some thing out for you mate.

Stavros · 06-12-2007, 13:11

As mentioned when tested for the spark it was perfect, as its wasted spark 1 and 6 fire at same time, so easy test of putting number 6 on number 1 without effecting no.1s firing proves that the ignition is fine.

The injectors are firing, we tested each one, and it is clicking... and stavros you chaged the injector over, so there is no reason to which it shouldn't be firing now. As the number 6 injector was now working perfectly in number 3 location, so we know the injector now in 6 to be of good working order.. still leaves a slight question mark over the wiring...possiblty

So we have fuel and ignition, which made me wonder if the inlet gaskets have gone, they are only made of crap on the RB26 and because its per cylinder throttle bodies and having a paper gasket in front and behind the throttle body there is a good chance they may have failed, they are known to blow out at Bar of boost, is why i suggested this, and in my mind IF its not electrical this would be the only other cause i could possibly seeing causing the fault, because logically when the throttle plate is shut, its vacuum could be drawing massive air in from outside, from the gasket behind the throttle body, which as entering the system after AFM would be unmeasured and cause that cylinder to not have correct mixture, then when the throttle plate is opened it would be over whelmed by the incoming mix and start to pick up a little.

This is how i saw it, but stavros, to check if its gaskets spray some brake cleaner down the back over the area were there the gaskets are, if the idle picks up or splutters you have a leak. but remember brake cleaner can catch fire easily, so do it a squirt at a time... not covering your whole engine in extremely flammable liquid

Either way as i mentioned charging them for steel is a great upgrade to do anytime.

If you need someone to come lend a hand or just do the job for you, let me know, i have a place up here i can work on cars so if there is a few things need doing, maybe i can help you out.

Clarkey.

Alex B · 07-12-2007, 09:33

We've had inlet gaskets blow a couple of times, but its always been at tickover and clears at about 2krpm?

My inlet gasket went on the CA at Teeside, car would barely idle and would misfire when revved.

HKS inlet manifold (1) and throttle body gaskets (6) cost me about £30 from I cant remember where, Sumo Power possibly. I agree you might as well do them if it's a possible cause but personally I'd be surprised if it was. I'll give you a hand if you like - I've done it before, its not a nice job.

Stavros · 07-12-2007, 15:02

Id appreciate any help I can get TBH mate.

Im gonna whip the cam covers off soon as I get a chance (tonight/tomorro) just to make sure the cams still have all the lobes on them

Then I guess next job is to remove the inlet. Ive sprayed WD around it, no change, and what its doing does seem odd to be it, but who knows.

I really hate RB26s and if I had it my way id remove the engine and start getting the car fitted with something I do like, but I want the car on the road, well, i want to drift, so guess that isnt an option.

N22CK_C · 07-12-2007, 15:19

dam just caught up since the last time i had read sorry to hear your having bit of trouble keep at it tho you will have skidding soon

**James** · 07-12-2007, 15:29

you done a cylinder compression test Stav?

superclarkey · 07-12-2007, 16:52

Yeah he has, i think he told me it was 10bar across all.

Nelo · 07-12-2007, 16:53

Compression test was done James but a Leakdown test wasn't. Compression was Ok but generally can be ok even when there is a valve(s) not seating correctly. A Leakdown test on that cylinder should tell you if you're have any problems like this though.

superclarkey · 07-12-2007, 16:55

well you have to work through and eliminate possible causes, i suggested inlet gaskets because i know they can do funny things, and also because the problem got slowly worse ect.

upto you if you don't want to change them, but its a job worth doing none the less.

Totally agree, but if a cylinder is infact seeing the same compression to other cylinders and the point of ignition.. it would still fire, maybe not as well but it would.... this is flat out not doing anything.

If it is wiring, its wired how its got progressively worse over time, and its consistent.. you would think if it was a dodgy wire it would come and go.

only trying to make surgestions, something like a cam would have been instant, not progressive, so i think that rules that out ect,

Either way i hope you find out whats causing it, will turn out to be something retarded.

Nelo · 07-12-2007, 17:07

Blocked fuel filter

superclarkey · 07-12-2007, 17:08

lol, that may be the case if it ran 6 fuel fitlers haha

maybe the fuel just don't like no.6 and flows past it......

gtst lad · 07-12-2007, 17:10

Just trying to help out here, have you checked the throttle butterfly/linkage etc for that cylinder?

Nelo · 07-12-2007, 17:11

Yeah could be that special "5 Cylinder" Fuel they used to run in the old Group B Audi Quattros? Maybe try emptying the tank of fuel

sprang to mind for me, mentioned it to clarkey, but he said (quite correctly i believe) that the throttles are joined in twins, so just 1 wont be shut on its own.
