Coil Pack

[dipsomaniac]

gone back to basics to identify misfire. does anyone know if these cracks on the coilpack would cause a problem? did not see any sparks around the coilpack when engine was running (badly). vw quoting

[Guest 3.5bullet]

they could cause problems? depends on how bad they are and if they are holding moisture? stick it in the oven on low heat for an hour then reseal the cracks and see how it goes? also try Ford for the replacement coil pack IIRC they were cheaper than VW last time I needed one! alSo try GF&S

will also be replacing ht leads. i only replaced them just over a year ago - 2 are now arcing. can anyone recommend a good set? Magnecor look good but i don't think my budget can stretch that far.

 

i was once told by a ford mechanic that i should always put contact grease inside the ht lead cap. Does anyone else do this? i don't know whether it has any effect but it does make a mess of the plug and cap.

I dont know if Ford are same but VW now have a lifetime warranty of coilpacks as our 2001 VW Bora recently had it replaced FOC & its out of warranty

pre 2000 coil pack are not a problem as such hence no free replacements, also the later coil packs your talking about are a different kettle of fish when it comes to failure rates and free replacements!

They also sell the HT removal tool - essential for the job !

 

Essential?

[dipsomaniac]

i had a look at those bigdaddy. don't think they would even fit as they don't have a 90 deg bend on the coilpack end - you are very restricted for space on that side. they look like the varing size leads your can pick up very cheaply as halfords - don't know about quality.

 

the set i bought last year were from partco -

[sepulchrave]

Dipso, get the 8mm lead set from magnecor, as you have now proved to yourself:

 

'If you buy cheap you'll buy twice'

 

Don't fit crap leads again or you'll be on here next year asking the same questions!

enjoying cycling so much haven't got around to fixing car. trying to find epoxy resin. found some at my local marine shop but only in industrial quantities.

 

does anyone know where i can find epoxy resin in small quantities? what is the difference between epoxy glue, epoxy weld and epoxy resin. can i use anything else to seal the coil pack?

Araldite, at your local hardware store.

RS Components and Farnell do small packs of epoxy resin and a variety of viscosities. But, be warned! Its very messy and a little toxic too...Epoxy is the only sure way to ensure sealant runs deep into the cracks - it will also run anywhere that hasnt been masked and sealed off properly! 24 hours to cure at room temperature...and you need a vacuum chamber to ensure the resin is pulled in all the way...

 

The problem with cracks is that moisture and dirt will likely be deeply ingrained. You will need to clean the pack - ideally in an ultrasonic solvent tank, or use an aerosol brake cleaner, making sure to blow out the cracks. Then allow a couple of hours to dry. You will then need to bake the component in a low temperature oven - maybe 70 deg C to ensure the solvent etc dries out thoroughly - this is important.

 

You could use electrical/electronic grade silcone sealant (expensive) - not shower sealant as this contains vinegar or araldite, though the adhesion properties of modern araldite is very poor and IMO will not seal in a satisfactory manner. To use epoxy resin you would need to improvise some masking or mould to stop the epoxy running elsewhere.

 

In the end theres no guarantee that the coil pack would be any good.

[El Dingo]

Seat Kid is right.

I shouldn't have posted 'Araldite' because it makes it look like I'm recommending that as a repair.

 

Personally, I would be 'phoning around OEM suppliers, like Garrett-Wright in Slough to buy a new one. Or if money is tight, 'phone around the breakers yards.

 

But, of course, it's not up to me to tell you to repair or not to repair...

[dipsomaniac]

thanks for your replies. i really don't think it is the coil pack as the cracks are in the outer rigid plastic and not in the epoxy sealed part of the pack.

 

managed to find epoxy resin in Maplin Electronics - comes in 28ml mixer tubes. ended up using a temperature resistant waterproof clear adhesive to fill/seal the cracks.
