Gapping spark plugs help

It should have all different thickness blades and can combine multiple blades to make more

 

What is accomplished by doing this?.

 

Runs alot better

 

In what sort of way?.

 

Its hard to explain, but it is recommended by mappers, did mine, and felt it ran alot better, it smoother and feels likes it pulls better when accelerating.

 

A smaller gap gives a stronger spark as gap is easier to jump, larger gap gives larger but weaker spark. Re gapping comes into it own with lager flow injectors as greater fuel flow can actually kill the flame of weaker spark.

 

What are you gapping them with?. Washers?. So is it worth doing on a standard engine?

And yes it is

 

Gap them down to 0.6mm using a feeler gauge

 

So all I need to do is insert the correct feeler gauge and the tighten correctly and pull feeler gauge out. Job done?

 

Yeah, its really not that complicated

 

Thought I'd ask the question as had not heard much about gapping spark plugs before. Was intrigued as to why and how it was done.

 

Plenty of info on Google, will tell you advantages and disadvantages and cause and effect ect

 

plus need a degree of gentleness as can destroy the electrode tip, place the correct size blades in gap, if its not snug fit gently tap the earth strap on hard surface (engine mount) and measure again. I say gently tap as most folk tap too hard and close gap up too much, its at that point of trying to open the gap out again that it all goes wrong.

 

.....there's probably load of grit down inside your plug hole that will simple fall into your engine when you remove the plugs, have you thought how you're going to remove that ??

 

To be honest when I seen this thread it just caught my eye, I have heard a small bit about people doing it but I didn't really take much notice but when I seen this pop just thought I would ask and look Into it more. I've changed spark plugs before and never had that problem. If is the case and then how would you recommend going about it?. Haven't changed the spark plugs on my 250 as of yet so not sure until I look.

 

Well a fitter would use hi power air line, something a home diy won’t have, the rubber seal around coil pack over time can become kinked and allow water and grit to lay around the plug. I’ve developed a suction tube that slides over plug and connects to cordless vacuum cleaner but making that’s a proper faff as well. Could try look down the hole with powerful torch might be lucky and it’s grit free. You’ll know something’s fallen in when you tighten plug back up a hear little crunching sounds

 

Small grit in combustion chamber wont afect a thing. It will be suspended in air and taken out the exhaust. And no it wont damage the turbo! No point of overcomplicating. You only have to be carful that the sprk plug base is clean so it seals.

Regarding water, silicone greace should be used or at least silicone spray, in the coil. It is hydrophobic and wont let water/moisture come near the HV part and short the sparkplug.

I used the spark plug socket, taped to another socket taped to the end of the hoover attachment, allowed me to collect the crud around the plugs without it falling into the chamber

 

Lol, that’s exactly what I’ve done, the tube part lives hidden in garage while Mrs cordless dyson lives indoors, they come together covertly once a year for plug change and works superbly at pulling grit out from around plugs
