Default LTCC Coil Conversion Pictures

Folks, the ones of you that still have access to your pictures, could you upload them here to the forum ? With the recent changes to the photo hosting sites that want money to enable third party (ie: a forum) hosting, the great pictures that you all posted when you documented your builds are unavailable.

These were a great resource.

So, if you would, please attach them to this thread using the tool set above to upload them. This way other folks (including myself) will be able to see what you did.

I don't think any text is needed, that is back in your original postings.

Thanks !

Do those seem to make the engine idle and run smoother?

How much taller are your valve covers than stock? Does it fit under the stock hood with the coils on them?

I'm using the Proform center bolt valve covers with Chevrolet script. Their a little taller than stock but there is plenty of clearance. I have had some fabrication work done to them for a catch can, oil fill, and to allow clearance for the stock alternator. I wouldn't consider them a bolt in part.

Thanks man. I was concerned with the alternator clearance as well.

I have at least 60K on mine with no problems.

My setup is a bit uglier than most.

Nice ... It seems like these kits all end up on garage queen cars.

I'm not sure that is a fair assumption. Mine, and PLRX's are certainly not garage queens. He actually has the documentation to prove it. I've been opti trouble free since I installed mine in January of 2015. I don't get to drive my car as much as I used to as I have a company vehicle now but I drive it as much as I can.

I've lost 2 Optis since I installed the LTCC November 2015 (I went back and looked it up). @120 weeks * ~500 miles a week that's 60K miles. The 2nd one went out this morning on my way to work. They last longer but not forever.

BTW, There are garage queens, drivers, and mine @ 500 miles a week.

Well that's all fine but neither of you said anything about the miles you have on your systems.
I tend to not trust aftermarket systems, which is why I'm wanting to know more about durability.
I'm not helping myself by replacing one system with another, unless its more reliable.

I have roughly 30k miles on my conversion. I am sure PLRX is over that.

Keep in mind, I had some serious issues finding quality opti replacements. I had a Chandler opti crap out after 1 year/15k miles. Then I had an Advanced Auto Cardone unit crap out again after 1 year/15k miles. Then I had a Delphi with a "Mitsubishi" sensor take a dump after 6 months or so. Then I installed a Petris Opti and LTCC kit and all has been well. I am not saying its the end all be all for reliability. I get it, you can buy 10 optisparks for the price of an LTCC, etc..etc...

But, the last opti cut out on me in the middle of US19, in New Port Richey, in mid day, with heavy traffic buzzing by. So anything I can do to minimize that nightmare from ever happening again, I will. It was not fun, or safe, or inexpensive to get towed home.
