Engine problem

[MWOOLY10]

Well its a new engine so im hoping it just needed a running in period of a few hundred miles to get it going..Although i wouldnt mind a few extra miles...

Noone did ever answer my question though so while your here

Do you know anything about these Techno Clean things..Any good? Know anyone thats tried one?

[AndyG]

Never heard of a techno clean thing unless you mean a fuel additive/cleaner

I've never heard of it either, just Googled it and came up with nothing.... do you know how its supposed to be spelled?

They sell them on ebay.Have done a search and it seems ok..Just wondered if anyone has used one or know anyone that has..



Just searched ebay and this is what i mean

Back onto the engine bit..Just been somewhere and i wanna know if what hes telling isnt a load of balls..

Just been told that the jerk on the gearstick was the fact that my leads were causing the van to miss fire..and hence the jerking on high revs when hot??

Anyone tell me if thats could be the case or was he just trying to get out of it(Mind you they were packing the van up to go to silverstone )

It might not be such a stupid thing to say. I had the same thing happen on a Pinto admittedly it was due to a cracked exhaust manifold but the result was 2 cooked leads around the insulation. I had the AA out the first time...couldn't find a thing, 5 hours later same thing, another AA man but this time but as it was dark you could see the spark arcing across from the lead to the manifold/block, symtoms of the driving were the same as you describe the jerking when harder acceleration was used. I swapped leads and drove very slowly home. Fixed the manifold, all was good for a while and then it cropped up again...yes the manifold had gone, replaced it again (the manifold) tried again..in the meantime I went and got a proper manifold as the other two were pattern versions, the wall thickness was over double compared to the pattern part also whilst this last pattern manifold was fitted again a plug lead burnt out but all on it's own, the proper manifold never got to be used as I changed vans I still have it somewhere. So whilst I am unsure of the layout of your particular engine with regard to the exhaust manifold and the plug locations it could be either the same problem or just the HT lead dying.

It could well be the leads, I thoought you had changed them though?

I wouldnt trust that technoairclean thing, they can even construct a sentence in their advert, its supposed to do the same thing as all those 'lead replacement' jobbies that were around a few years back, the only one I was ever happy with was the 'System4' 'fuel catalist', works on aexactly the same principal as the one you have seen, but unlike all the others I tried it didnt rattle when you shook it, and 5 out of the 6 I fitted to old cars are still running perfectly (the sixth went to the scrappie cos of rot, it was a maestro after all ), Im sure that most of them just have a couple of lumps of Lead in them

or is it one of those magnet things that where about a few years ago ??

Yes thats the principal Andy, in theory the fuel atoms are indeed magnetic, its been proven. But some of these gadgets are a lot better quality than others, what I'm saying about the 'technoairclean' one is that if they cant be proffessional enough to make their adverts make sense then how good is the product going to be?

Well my mainfold isnt that old as it was cracked when i got it..So im hoping to get the leads changed over the weekend and hopefully that'll cure it as im off down south on sunday..

Oh well looks like i'll try and find another way to save fuel then...Cheers for the info

On the old engine that knocked i got about 380 to a tank .. On the new one just got roughly 420 so im hoping it'll get a bit better the more it is run in as it still seems a bit rich when you smell at the exhaust pipe but its only done about 500 or so miles so will keep my eye on it

Have I read that correctly, your manifold was/is cracked? If so there is your problem and no amount of lead changing is going to fix the problem as the exhaust gases are going to cremate the lead everytime you use the van until you fix the manifold...also if it is missing replace the heatshield as it does actually do what it is supposed to, loose ones touch the HT leads and heat transference from the manifold will result in the same issue this is going to happen even if you have replaced the manifold but make sure you buy the correct bolts for fixing the heatshield. I learnt the hard way with a cracked manifold ( 3weeks after doing the job) after using the wrong bolts

[MWOOLY10]

no it was cracked when i got it..but i renewed it straight away sorry for the confusion..

btw my manifold is on the right as you look at the engine and the leads are on the left and go on the front of the engine so theres no danger of them touching eachother anyways

[MarkM]

Ok I did say my problems were with a Pinto...wasn't too sure of the layout difference, but it is still sounding like a fecked lead.

[MWOOLY10]

Cheers for that..Will try and get some new ones
