www.gti-vr6.net napisal/-a: 4) It seems that the VR6 coil packs (at least pre 98's) just suck.
I am not sure if the plastic is not formulated properly, if the molding is
not performed properly or if the design does not distribute stress/heat well
but by listening to the problems people on this list have had, the coil pack
is NOT a quality part. Either that or it is designed obsolescence, keeping
the dealer stocked with easy, $500 repairs every 30,000 miles.
Lucky for you, there are engineers out here who just can't stand
it when a biased party tells me that an inferior part needs to be replaced
with the same inferior part. So like all good men, especially engineers, I
start to tinker. Leading to a "fix" that has worked for 11,000 miles so far
- The $3.49 Epoxy Solution.
Part IV - The $3.49 Epoxy Solution
1) Drive a different car to Home Depot, Lowe's, etc. and get a
package of high strength, high temperature epoxy. I *think* the brand I
used was "Poxy-Weld"? It is the classic twin tube syringe, silver in color
with a cardboard packaging display that unfolded to give product
information. It is made to repair metal, plastic, etc. with higher
operating temperatures. It has Kevlar flakes to add
strength. I think the one I used was rated to 250 or 350 degrees. It was
like $3.49 for the tube.
6) Take coil pack inside. Ignore the "you are not a mechanic"
insults coming from the living room (be the ball Danny). Take off plastic
cover on the top of the pack (just pop over the small clips). Wash off the
coil pack with a damp cloth. If it is really dirty, a bit of Dawn can work
wonders. Just make sure to wipe off the soap well. You will now want to
dry the pack WELL with the hair dryer. I was probably a bit anal about it
but I sat in front of the TV for like 20 minutes just drying the pack.
Since there is no real way to tell if all the water is out of the cracks, I
was conservative.
7) You are now ready for the epoxy. Mix a healthy amount is a
small disposable container. I used a popsicle stick to mix and spread.
Start applying a liberal coat of epoxy. The first time I did it, I only
covered the places I had seen sparks. Of course about two weeks after the
first fix, a new crack or one I had not seen developed so I did it again.
This time I covered the entire plastic portion of the coil pack.
Concentrate on the area between each terminal and the edge of the pack. No
problem since. So either coat the cracked areas or just do the whole thing.
I would recommend the whole thing. The epoxy tends to get a bit sticky so
it may work best doing two batchings.
