Venting Cop's Cover

I want a cowl hood, something like this

Head temperatures are among the highest on an engine. That is where your cops are, sitting on top of spark plugs that act as heat conducting rods right out of the highest temperature location in the engine! I'd say that the answer lies somewhere around not using OEM COPS and getting something with a beefier design. As was previously stated, the Intek 32 valve Mark VIII engines don't do this. Neither do a whole lot of other engines, although they are all operating in the same temperature range. It's just a crappy OEM coil!
 
My Accel coils have been installed in such a way as to stand up above the cam covers. The Accel boots seal the tops of the plug wells. I've simply left the covers off. No problemo!

if the car does not have coil covers - the boots usually have a flange that 'seals' the spark plug well from letting water get down in there. THe LS V8 boots do not have this - so you would open to that issue.

you can see the flange that seals against the well on this pic.

Do you have the part number and cost you paid? Are the coils your using for a mustang or crown vic, etc? My misfire is getting worse and i'm going to just replace all eight coils myself instead of paying the dealer to find the failing coil(s). If these coils can be used without reinstalling the covers that makes the job alot easier. Any pics of the install? Are they able to use the stock bolts and wiring to hold them in place?
 
I'm sponsored by Accel so I don't have a price. They'll be easy to get from Summit. Ask for the items for a 2 valve Mustang V8. And please note that by leaning the coil body to one side slightly, and using a longer screw, it's possible to fasten them to the existing screw holes on the cam covers.

Well, gee.... thanks, but i did do a search of cammerfe's posts to see if he did a write up of his install but after about 8 pages worth of posts i had to give up. Didnt know any others went this same route. I went to the accel website and there are a couple different types of these coils so i wanted to get an exact part number. This post explains the whole process, $200 aint too bad if they do in fact give a slight performance and mileage increase. I am not quite understanding how the "clips" shown are holding the coil in place. It looks as though the bolts are in the original location but the "clips" are holding them in by just the tension/pressure of the clip on the coil? Also he said he reused the original boots instead of the accel even though he stated the accel "could" be squeezed in, i thought the whole advantage of the accel boot was to provide the flange which allowed the cover to be left off?
 
no - they went to Accel hoping they would be more dependable.

and it seems the accel coils fail more then stock..............

because the coils are taller, they need to use taller bolts, then add a washer to catch the edge of the mounting flange to hold them down, since the mounting hole does not line up. So the coils are basically pinched into place.
 
Well thats just great, I didnt quite get putting a coil that isnt designed for your specific engine, but they said it worked. I'm definately not going to put motorcraft coils back in my car and do i still plan on switching out all eight fairly soon, it would have been nice to not have had to put the covers back on but oh well. I have seen a variety of people who have installed LS specific aftermarket coils, now i just wonder which are the most dependable. There are alot on ebay but i dont think thats the direction i wanna go, swapping the coils isnt the easiest most fun thing to do but i wanna make sure i can depend on whatever i am putting in my car.
 
I hate the Accel stuff personally, I plan on going with the Summit brand coils. which are most likely the MSD ones re-branded, Summit is known for this quite well but mainly uses Mallory for their ignition components but since they dont make 4.6 COP's they rebadged the MSD ones. Heres pics of the two, you can decide.

Thats funny..............the top one looks EXACTLY like the units in my V10 F250. Well except mine have ford decals on top of them.
 
Alot of stuff that you spend your money on these days goes to the company or "Your paying for the name"

And which is even better, the Summit brand/name is backed quite well, Ive never had any complaints or problems with their products or customer service.

I believe there are only Ford replacement - period. there is no LS aftermarket part - hence why people are trying mustang, F150, ...etc. The ones on e-bay are either 'new Ford' or 'refurbished Ford' - but to my knowledge they all have a 'Ford' sticker and partnumber on them. I have purchased off e-bay twice - and they look like brand new Ford in the box coils.
 
I don't understand why there is a discussion about whether or not heat causes coil problems. When cars used to have one coil mounted on the engine somewhere performance coil manufactures always recomended mounting the coil off the engine on a fender well for example when replacing a coil. If you ask me the current expensive arrangement on the LS is the dumbest idea ever. Lincoln states that the reason for COPs is to save the customer the expense of buying spark plug wires. I'd rather replace spark plug wires any day.

Ford indicates...
"Some of the vehicles may experience an engine misfire condition predominantly due to internal
breakdown in the coil and lack of adhesion between the epoxy and the coil housing material."

While they don't say it, it does seem reasonable to think that heat may be a factor in this.

this is the way all modern engines are. The new hemis, then LT/LS form GM, all the Ford Mods, Lambo, Ferrari, ...etc - all use Coil-on-plug. It allows for better PCM control over individual cylinder spark, as well as allowing more time between the coil firing - which means better coil saturation and 'potentially' a higher discharge. Single coils, or coil packs are all but gone.

Never heard that statement - the benefit is that it removes one more failure piece (the plug wire) from the mix, once you go with a seperate coil per plug, why bother with a plug wire...


That said - I agree with you that heat is one of the causes of failure (water, oil, vibration, ..heat), but not a issue with the overall COP design of an engine - but with the actual poor quality of the particular COPs used in the LS. it does not appear that other manufacturers have as many issues with COPs.

AFAIK, Ford doesn't have as much trouble with their other COPs as they do with those on the LS. Hell, they don't have nearly as much trouble with the COPs on the V6 LSes as they do on the V8s. Maybe it has something to do with the Jag ancestry of the AJ V8...;)
