Why is it that you find a problem just after the Factory shuts for the day?

My starter has started making a strange noise so I whipped it off to investigate this afternoon only to find it is breaking up inside and is therefore not long for this world.

But of course it was too late to call to see if they have a replacement and I have an MOT booked for Friday!!!!!!

I hope they have one, and I can see a trip to Hinkley on the cards for tomorrow.

My sympathies Paul - I am sure you will get it done in time.

..however I have my own woes as well! ..so we can moan as a duet if you like!

IVA today and....... FAIL! - you won't believe how much trouble I went to to try to make sure it was OK - I even became a Scottish-Buddhist just in case!

Couple of little incidentals that could have been sorted whilst I was there, and they would have let me, bar the biggy!
Failed emissions on idle - passed at fast idle and 2500-3000rpm -

To be fair to Martin who did the test he tried oh-so-hard to give it a chance with 3 test cycles in between high revs to clear things out..

...but it did for the engine... started to get far too hot, was too late for the blower (I should have insisted that they put it on right at the start)...

At one point the damn thing went into limp mode, which was amusing to to others watching as it was half on and half off the ramp!
Waited for 10 mins and all was back to normal!

I am going to have to look at doing something to beef up the cooling smartish... the fans seemed to struggle, but more so I don't think water flow is really sufficient at idle from rad to engine...it's got a long way to go (front to back), far longer than a corvette, but holding it at 3k revs helped significantly in cooling the engine and the oil!

I had invested in getting Paul Spinks up from doon-sooth after many recommending him as the GM ECU Guru - and he spent all day at mine remapping the engine to get it through IVA...but that was 5 months ago...(which raped my wallet AGAIN!)

I suspect all the starting and stopping that goes on as you near the end of the build did not do much for the cats, but this is unavoidable!

I just hope that Paul can help or I am scuppered!

Keith

PS: one thing I proved - leaving the car at 110 height at the front did not cause much hassle and this passed the headlamp test and all the lights were at the right height to pass...and we managed to get it on the ramp, with the help of a couple of plates!

Sorry to hear your problems. You must feel quite deflated!

I think you should look at using a rolling road to get the engine set up. A good rolling road will have the ability to measure emissions to check the results of the tuning.

Running the engine at high revs for long periods when stationary will cause overheating. There is no way the cooling fans will cope with that. I would not look to make changes to the cooling until you have tried the car quite a bit on the road. Insist on an assistor fan during the next test.

Sorry to hear of the fail.
I know how you feel, I have a car in the workshop which has defied all atempts to get it near the emissions figures.

In your case it may have been that it got too hot. I can't be sure but I believe the GM ECU adds fuel if it gets too hot presumably the engine would run cooler on a rich mixture.

Oh dear, sod it indeed! I'm sure you will find a solution for next time. Just for my info, when you go for another test, do you have to pay the testing fees again?

dont know if theis will help, but last night i put a full tank of E85 fuel in the family load lugger for the first time. most other times i have been mixing it with some of the reqular 91 octane unleaded that we get here in Australia.

anyway so thismorning i jump in the car to head to work and even after an hours driving in stop start trafic the nedeel on the temp gauge is still 5 degrees cooler than when its on regular 91 octane. havent changed anything else.

have also heard that E85 burns different and gives of different gasses so it might give you a different emissions result. not sure if it would be better or wors due to the type of fule or due to the engine temp.

Powerlite HiTorque starters, miles better than std. And cheaper to boot.
Speak to George Shackleton (yes he IS a relation to Ernest!), he put me right after trying to order the wrong unit for my G50/52.
They were able to send it in short order.

I am sure my Factory supplied starter is a Powerlite.

Thanks for the contact if the Factory can't help.

IVA test fee is £450, Retest fee is £90. However there are some catagories of fail that do not require a retest fee.

The guys at Nottingham never mentioned a retest fee, just said give us a ring on our secret number and we will squeeze you in within a couple of days!

Yep, it is ONLY in idle - all other (fast idle and 2.5-3k) is better than fine! Mind you the car seems somewhat rough on idle - felt like a plug missing occasionally. Could be an O2 sensor not recycling properly - could be many things...

Paul did ring back quite quickly - one idea we had was to have him (with laptop plugged in) in the car whilst the test was about to go ahead so he could tweak! - never heard that before, but sounds logical! Don't know if the lads at VOSA Notts would be OK with this?
Thinking about it, surely this would not infringe any rules, and makes real sense?

Wonder if I should ask the question?

At my local station the test is done as a set sequence that the machine runs.
I would expect them to let you/mark make an adjustment and disconnect prior to retest. Otherwise you could be changing settings to achieve each parameter as it went through the test. My guys have worked hard in the past to help me get a car through.

I believe the free retest only applies to things like inspecting the sharp edge you have cured or a fog light now working only with the headlights etc. Something they can do without much effort.

Had confirmation from Andy up at VOSA say he is happy that tweeks are made up there...

Sounds like the way to go if I can...

Only issue is getting it there..again! 165 miles each way..and the cost of transporting is ruinous!
I don't think you can change stations for a retest!

Driving it up there would open a whole new can of worms, something I would not like to do, since it has never had a shakedown, which is not really possible given the lck of an off-road test site, and regs being what they are!

Good news on the ability to do some live tweaking, hopefully that'll give you the bandwidth you need to pass the emissions.

Now that the car has been inspected, you should have confidence in the build quality and I would say a drive up the road is of less concern than the first time it turns a wheel on the road (like I'm going to do, LOL!). Go for it wink

You know....

If I was 30 years younger, I might have been tempted to take a chance and give it a blast around the country lanes to see what might fall off or fail, ready for a (MUCH) longer drive!

BUT

I am old..my license is very precious to me, and the thought of that slimmest of chance that I pass a police car going the other way... or worse still...something cuts the engine or a horrible noise that means I must stop in the middle of nowhere... and Mr Plod just happening to come around the corner, would give me sleepless nights....

Knowing how my luck is panning out at the moment - I would not like to take that chance... unless technically I could get away with it...

Yes! I am a wuss - just in case you are thinking that! tongue out

Ted was expecting my call this morning and I collected a new starter before lunch.

Fitted it this evening, but it now looks like I need a new starter ring. So trans out once it passes it's MOT on Friday (hopefully).

So Ted, I want a ring gear and clutch friction plate for the pressure plate you supplied during my rebuild please....

This overheating problem on idle ... will an electric water pump in series with the engine one help to keep the flow of coolant at idle speed flowing faster?

The readings show that my engine passes fast idle and 2.5-3k rev tests, but not natural idle where it was way too rich.

PaulS who I used said they normally fail for the reverse, Idle is usually OK, so if he can he is popping down this evening to see what has changed (he did the original set-up for IVA).

The engine was set up lean on purpose (for emissions) so this has contributed to the heat problem.

I am looking around to change my fans as they did not cope very well - but:

Pacet are no more!

The owner has died recently, the company went into liquidation, then Kenlowe have gobbled up the remains including any Pacet parts.
The Pacet website contact details now channel you to Kenlowe!

I did ask for Pacet fans but they say that they can no longer obtain the motors - and were very keen to sell me their own unit. BUT they are lower specced.. however I am considering it.

Demon Twerks have no stock any more and are concentrating on Kenlowe and SPAL - the latter are only a few miles away for me.

I was not impressed by DT's attitude in trying to squeeze me into SPAL fans, mainly because when I asked him of the precise spec of the SPAL replacement, in that I wanted a realistic alternative to the Pacet KPF1111P, he said that his buyer had taken a lot of time matching specs from SPAL and these fans would have the same spec....
When I asked for precise dimensions, consumption and CFM ratings, all he did was repeat his last statement... so I smelled a rat!

I rang SPAL and spoke to the MD... There ARE no direct equivalents - DT were bulling!!!!!

Apart for a hugely expensive 10inch rated a lot lower than the Pacet ones, which is way too thick, the 11" was the same depth and over £200 each, but still lower in the air moving dept.

The ones offered by DT (£62) were not far off the factory standard air-moving capacity - so no advantage!

Kenlowe seem to be the obvious choice, but what else is out there...

Pacet RIP!

The Kenlowe seem to be much lower in cfm compared to the Pacet...a 10" ken is 705 cfm - Pacet 10" is 1049 cfm
