Injection rail

Technical Area Engine, Transmission, Exhaust etc
2

can some one give me some advice please.

just fitted another 1.8 engine as my son cooked mine big time.

anyway fitted engine and injection rail what a pain to fit and so fidderly.

started up the car and i could see a little flame glow on number 4 injector.

so took it all off again and I just had a spare set so I put that one all on double checking that injectors were in properly and bolted down all nice and square, and all the wires back on.

now imagine bonnet up, you open drivers door and put your arm in between door and windscreen to turn the key, whilst your head is under the bonnet watching.

turned the key, engine turned over there was a load backfire and a great big flame from number 4 injector,

there go my eyebrows and some head hair, 

And then the engine is on fire at the back so whilst trying to BLOW the flames out that’s no good, I then run in doors and filled up a jug of water and throw that at the flames no chance so another jug and leave the tap filling the bowl, 2nd jug thrown the flames just laughed at me.

by now my bottom was doing ten to the dozen, finally the bowl was chucked over it and the flames were out.

there must be an easier way to keep warm in the winter.

when everyone stops laughing it’s fine cos I’m doing that whilst recalling that day.

what have i fitted wrong .

I just shut the bonnet and went indoors to consol my lost hair and eyebrows.

O rings at the top of the injectors nicked, split or missing?

should you be working on cars?

Can we find this on YouTube? I could do with a good laugh…

Well thanks for the first comment should I be working on cars.
It’s a bloody injection rail that just pushes on snuggly and then you tightening down.
Didn’t expect a big bloody flame as well

What are you doing Busapower?

Your son messed up your engine , surely it should be his eyebrows and head hair patinating the underside of your bonnet.

Two words for WHENEVER you’re doing any work on any fuel system :

Fire Extinguisher.

But then I guess you know that now.

Yes I bought a large garage sized Fire Extinguisher for my garage and quite a “few experts in their own bath tubs” who have an opinion on everything.

Especially about how capable others are at doing pieces of work while they can do nothing properly, were smirking about someone buying an extinguisher for their own garage as it is just a waste of money!!!.

I was talking to an experienced process plant manager who advises that people will complain about the quantity and quality of protective clothing at work but at home will not spend a penny on safety gear to do DIY, like proper boots, gloves, ear and eye protection and when working on flammable items like car fuel systems fire extinguishers.

10

I have always been really bad at taking proper precautions with the work/jobs I do. Not just on cars but roofing, treework, etc, etc. In truth I feel very lucky to still be alive let alone with four limbs, two eyes, etc, etc. The job is never more important than personal safety - hopefully an obvious priority that others instinctively see more clearly.

Whilst welding a patch on the underside of my Golf Diesel, some MIG wire perforated the plastic fuel pipe which ignited the leaking fuel. The flames were everywhere and my gloved hands were both alight. Car was positioned just outside my garage so if the fire had taken hold, the car and garage would have been cremated. Luckily and I still struggle to understand how, the flames were extinguished and fuel flow stopped - my memory of that traumatic episode is incomplete. The point here is this was diesel - with a similar scenario involving petrol who knows what would have happened.

Don’t take unnecessary risks and a handy fire extinguisher or even a bucket of water whilst working on cars or anything containing flammable liquid is a very good idea.

PLEASE don’t think you’re safe with a bucket of water as a safeguard against burning fuel - or fats.  If anything they’ll make the fire worse, and unless you’re REALLY lucky, won’t extinguish it.

A bucket of dry sand, or fine soil, is so much better - if you really don’t think that spending £20 on a decent fire extinguisher is a worthwhile investment…

So, having read this thread, I returned to my quandary of many years, “Which one do I buy?”.

I think my house is reasonably safe, no gas except in a sealed condensing boiler, proper wiring with lots of RCDs, not much in the way of easy combustibles, solid internal doors, alarms, etc 

But the cars are another matter, they are full of combustible materials and have this habit of occasionally locking themselves unexpectedly, and we don’t have a soft-top.

We have a proper fire-blanket in the kitchen (never used, quite old now and not listed any longer), but nothing else.

Whenever I’ve done solder-plumbing (lots over many years) I’ve always damped down the surrounding structures, used flame shields, worn protective glasses, and kept a squirty-spray water bottle or two close to hand, and made sure the doors and windows were open, never a problem.  Even at work we used fume extractors when soldering inside electronics on the workbench, because the flux can be carcinogenic.

At work we had different extinguishers in the various rooms depending on what was done in them, as well as sprinklers in more public areas without much electrical stuff.  The regulations kept being updated, and the extinguishers were inspected every year and frequently replaced.  Trying to keep track was a full time job and we had proper fire-safety officers going around the various sites.

 

I’ve read the quite comprehensive article in the Wiki,

https://en.wikipedia.org/wiki/Fire_extinguisher

and I am still not much the wiser when it comes to trying to choose size and type for the car AND another for the garage from all the oddly numbered categories on sale, eg the reasonably big list at Screwfix

There’s good information here https://www.firesafe.org.uk/portable-fire-extinguisher-general/

I have 3/4 extinguishers in the garage as almost every mechanic I speak to , especially the older lads, have had some sort of car fire over the years.From fully burnt out garages incl cars to the odd small welding fire .Years ago I would have to sit in the car while my dad oxy/acyetelene gas welded the floor pans,arches maybe or even the silencers.I remember Ritmo,s Austin 1100, and loads other s*it of the day having small fires and I had watering can to quench the fire .Best to have several extinguishers available .I can source good ,fully charged, ones that are “out of date” for free!!.Moral of the story you were lucky really.Lesson learnt??

I used to manage small wire drawing plants. Unfortunately they succumbed to Far East competition like a large part of our manufacturing industry. One of the results, apart from having to find another job, was the opportunity to acquire good home workshop equipment and fire extinguishers. I have dry powder and CO2. I have twice had to extinguish a fire and my preference is CO2. This has the advantage of being clean and smothers the flames. The disadvantage is that it does not readily cool the area so needs  to be played over the area for a while after the flames have gone.

Motorsport people comment on how ineffective the regulation powder extinguishers are and the mess they make. 

Perhaps there is a fire officer who can comment.

Right well thanks for all the sarcastic comments, and no one else has ever caught there car on fire.

I have found the fault.
It was not the injectors that was leaking.

I have a mk1 mx5 and I brought a mk2 engine which I put in ok, I then put the inlet manifold gasket onto the studs, and fitted my mk1 inlet manifold onto the studs because of the wiring connections.

So does anyone have any comments yet,

Well the mk1 manifold and the mk2 manifolds are different as in the ports On the manifold are in slightly different places as in they are lower down on the mk1 but they both fit on the studs ok.
So when you connect it all up and crank it over the fuel shoots out from above the manifold as it does not cover the engine port properly.

And yes I do have a fire extinguisher to hand now.

I would not fit a MK2 engine to a MK1. Not saying it can’t and hasn’t been done but a lot more complication and expense than simply replacing the existing engine from a MK1 car of a similar year. I say similar year to avoid loom, ecu and other complications.

Most of the comments on your thread have been constructive. Just remember why you are in this mess in the first place.

Would have been a good idea to be asking questions about your choice of engine replacement before starting this job!   

18

What sort of drugs are you on.

This is a forum site to build old mx5 back to there former glory or do engine swaps and other stuff.

So people share there experiences and knowledge,
But all you seem to do is slag people off and run them down. Mr your so perfect.
Bet you dont even know what a ring spanner or a open end spanner is anyway.
And you stick your car in a garage to fix things as you are to incompetent to do it yourself.

Thanks for the entertainment busapower

A good fire act and fitting a square peg into a round hole - looking forward to seeing you at the circusCool

Mr/Mrs/Ms Busapower - what Rhino, and many others on here, don’t know about MX-5s, isn’t worth knowing.  Abuse gets you nowhere, other than attracting the derision of pretty much everyone else.  You didn’t tell us the whole story - perhaps if you had, constructive and helpful advice would have been a little more quickly forthcoming.

Glad to hear you have a fire extinguisher now.
