Quick Question On Coil Packs

[GTAAAH]

Can some one quickly explain where the cracks would appear on the coil packs on a rb20det engine? I had a look in the DIY section and theres an explanation on a 33 but my packs look different and they have a sort of plastic bracket around them that used to connect them to a metal plate but which i cant seem to remove

or is this not a problem on 32's as it is 33's. I had a look at some pictures of the packs in 33's and the plastic looks thinner.. The plastic bracket im talking about is plastic and has 4 screw holes in it. Its connected to the pack at either end by a piece that joins and goes into the side of the pack.

The mounts on the 32 coilpacks are metal, iv just gone through changing a couple on both of my cars. I believe they generally crack at the base of the carbon or spring stem that joins to the spark plug. take of the boot and youll see what i mean. Atleast thats what eveyone i have asked has said.

However iv had 3 coil packs fail now and both me and a mechanic i had inspect them could not find any cracks in the plastic. They just go

I have a feeling they start arking against the metal mount,because all the packs ov seen have been all white under there, like electrical tracks. but you cant get underneath that mount from what i can see to identify a crack in it or not.

ahh crap i just took them off checked them put it all back together again. THats the 3rd time, last 2 times i ran out of time half way through.. So what your saying is most of the time, any cracks will be underneath where the plastic boot is? As in ill have to pull the boot off and the bit of plastic or w/e that connects the boot to the rest of the pack will have the crack. Correct? Also im not sure if mine are gone. The car has always dropped power from about 5000- 6000, quite a bit but i assumed that was the turbo in it. It doesnt seem to miss, but occasionally i do hear a bit of a rumble at 5k rpm. Could that be the packs or is it probably just fuel related, and the rb20 stock turbo being to small

thanks

just need a lil more information on how to tell if there screwed. Take off the boot, then look at the bit the boot connected to i assume. That will be cracked? have hairlines? Have strange marking? Im almost totally sure its my packs, i have horrible spluttering at about 5k rpm and no balls, but ive already had them out 3 times and its getting rather tiring.

[GTAAAH]

never mind ill just try ignore the spluttering and power losses until i get the new turbo installed, then get it checked out professionally
