Header Install

[shady milkman]

When removing the AIR system, I noticed that the lines from the drivers side header to behind the drivers side head to some type of t-bar then to the passenger side header. My question is is there anything that needs to be plugged or removed at the t-bar when removing this system?

that sounds like your pcv...you need that.

part of the vaccum pump actually and it will cause a vaccum leak and throw codes unless it is capped.

really i am not aware of that..unless he is talking about the fitting on the back of the intake manifold ..but then one goes to the brake booster and the other one is hvac tube that doesnt connect to the heads. oh well

yeah I know that there is an area that needs to be capped because of this and I found a picture at one point. I'll look for it and see if I find it.

I am getting ready to do a header and cat install and this post was really helpful! I still have a few questions though. I looked up the pace setter LT and TSP cat and y pipe combo kit he used, and my question is why is ceramic coated better that just regular? And are those cats high flows? here is a link to the site they are sold at if you want to take a look.

Stainless > Ceramic > Paint. I have Dynomax Ceramic Coated headers on our Corvette, and so far they have held up well. Just have to be careful not to nick or scratch them during the install, just like with painted headers.

Yes, high flow cat's. They were the tsp like you mentioned but picked them up from kyspeed. I really am not a fan at all as I only had 2" ground clearance afterwards. I since raised the back end to stock again and still have right under 3" with the 3" catted y pipe. Sure would like to find a good 2.5" y-pipe or save up for some custom duals.

Oh and to keep from scratching, I actually kept the headers in the bag until they were installed. Just have the open side where it bolts up and then you can slide it off once the headers are installed.

[camaroluvr447]

how many inches of ground clearance does the maro have stock with no mods? thanks for the info!

Nice right up..Iam about to buy LT's and ORY. Would it be better to put the car on a lift to install the Headers and ORY. If I replace the motor mounts how hard are them to replace.Should I go with Poly or stay with rubber..

[marksls1ta]

lift makes it alot easier to do the headers. We have one and I hate to do them on the jack stands now lol. the mounts i have are poly and stiffen up the drivetrain some.

Thanks,
Mark

Do ya sell the poly motor mounts for the ls1..When I do headers I mines well do the motor mounts also.

Poly mounts are nice...check your trans mount too...lots of people dont like the poly trans mount but I dont notice to be honest. And I hope yours line up better than mine did...

Ok everyone tells me when I do LT's do Ploy Motor Mounts. If I dont they say the headers will hit the car when I get on it..I will check my Trany Mount also...Thanks Jimmy.

Hoe many miles? And why not do them while the headers are off.

low miles so thats up to you? Pretty inexpensive but it was a good choice for me at 87k

my bad ..i completely misinterpreted your post

[Joels1]

Purchase the American Racing headers an high flow cats.Were can I get the poly motor an trans mounts?Also are the vette o2 sensors just a stock item?

[bberretta]

Bosch 13111 sensors are just stock Vette sensors- same as stock f-body sensor but a longer connector. Don't pay more han $100-$120 for them- eBay seems to have best prices. Mounts can be picked up from Summit, Jegs, or any number of places.
