Pulled the coil packs out today and 5 have cracks. Not on the stems but under the rubbers and all the cracks are on the inside of each coil pack of each rail if you know what i mean.
What could be the cause of this?
Also the two middle plugs had a fair bit of oil covering them too(not submerged). Have tightened the rocker cover so see how that goes.
The plugs i pulled out, all on outer core a little black but each probe was slightly brown.
Id post a pic if i could get the pics on the PC.
Any help as to what could be causing this would be great...

Ok Sounds about right to me.
Is it worth going to a wreckers and picking up some second hand coil packs or save some funds and go some new ones?
How much are second hand coil packs worth? Anyone from South Eastern Suburbs know a cheap place?
Also is there a way or a good product to better seal the rocker cover on our cars? I know the screws i have to tighten every so often but after a more long term fix.

Sorta off topic and sorry Micheal. But im curious Danny or anyone that knows.
If you were to buy the Bosch Coil do they work better than the Standard coil packs?
Basically what im getting at is down the track i wanna buy new coil packs myself and a HKS DLI System. Is that better than the bosch coils, or is the bosch coils better?

I thought you needed aftermarket ecu to run bosch coils? The weak point but in the system is the ignitor for actual spark energy and to replace that you most diffinately need an aftermarket ecu, or you add a HKS type DLI.
Other than being slightly cheaper, what other advantage is the bosch coils? You need to run leads which is very yuk for ignition noise. How long do these last? As long as factory coils?

there is nothing made here in Australia that is any thing like the standard coils the primery and secondard windings of the coils are totaly different. i have actually rang bosch Australia and asked the questions the closest thing to them is the MSD from america but thay are really big suckers and would take up at least 1/4 of the engine bay to mount them Craig webber had contacted a guy in America that would be able to get original coils but you would only save about $15 from buying new here in Australia.

who did he contact? Have you tried elmhurst toyota for factory coils, they are cheaper than any australian toyota dealer, and they get it here quicker than australian toyota dealers.
Yeah, i was emailing them a while back about a new set of coil packs, including shipping it was going to cost ~$96 per coil pack, just over half the price of some over here. I think its worth it if you need a whole knew set.
here is my email: >Hi, > >The 2jgte coils are 90919-02205 list 90.00 cost 66.00 ea + 42.50 shipping. > >Check this part number against the one you have.

That's what I paid, but I also got the six brand new coilpack connectors (highly recommend) as well which ended up being a grand total of 633 AUS delivered.

Havent tried the heat shrink yet.
So far all i have tried is sealing the cracks off with silicone. Been pretty successful.
Dont know how much arching its stopping but have regained very much response and power. Feels pretty much like when i first got the car
Not sure how long this may last though with the heat but previously sealing cracks around the top mounting corners of the packs is looking good. No silicone has come off or showing any signs of heat damage.
This would have been about 4 - 5 months ago...
Im sure it would be hotter at the base of the stems rather then the top of the packs though.
Thought i had a major problem till i patched the buggers up LOL

Just replace them with new stockers! =P
I went through this same phase about 4 months ago. 4 of my coil packs were cracked. Car was still running however it just farted lots when i gave it a boot.
...you thought there was a point to that story didnt you.
