Default LS6 intake broken, possible repair/replace?

Hi!

The LS1 engine I bought had a LS6 intake since it was from 2001 but to my disappointment the intake had been damage when the car it was in had an accident.

The damage is below the power brake assist connection on the intake. (like a smal coin)

So I'm wondering if it's possible to repair and if so how to do it. (did a search and found JB weld to be a good option) Don't know if they sell JB Weld in the EU.

replace it with an upgrade?

Or any other suggestions...

I do not want to spend a lot of money but if the benefits of replacing the intake gives some extra power for the right price compared to a repair I might as well go that route.

Anybody?

Repair the intake and save some money for a cam upgrade?

Or get the following intake and make X amount of torque/power over the LS6 intake?

Thanks.

Depends on how bad it is. A picture would help alot. I think it depends on the break... and you repair ability. Ive repaired cracked intakes before, with no problems... but id only recommend that on a stock / lightly modded car. Never a power-adder car.

As far as replacement, ls6's are the best for the money. There are plenty of guys running 9's w/ the ls6... hell ive heard of it being done on the ls1 intake.

Thanks for the info... yea should have figured an picture would be appropriate...



It seems the vacuum port (the large one) has punshed the hole somehow. (I'd assume it's connected to the wall somehow)

Yah, that's nothing. Get some JB Weld (it's just epoxy), as noted, & fill the crack & void area. No need to replace the intake. That tiny crack probably isn't even causing a check engine light code, is it? Anyway, any epoxy that works w/ nylon or plastic will do the job. Just make sure that you let it dry completely before running the engine. Good-luck.

Hi!

Check light: Not sure only got the engine, going to install it in a 2ng gen firebird.

Just read up on the LS1 and LS6 intakes and they are made from one piece making a proper repair a bit of a problem, how do I take out the rear vacuum connection? (The big one)

You don't have to take the vacuum connector out. Just put the epoxy on your finger & fill in the area that is broken. This will seal any leaks & fix the intake.

Hi!

Btw thanks for all the help!

I've ordered some JB-Weld si it'll should arrive within the next few days and I'll perform the repair as soon as it arrives.

Even though a removal of the vacuum connector isn't needed I will most likely not sleep good if I don't remove it and get the piece of intake properly fixed in it's location...

Anybody know how to remove the vacuum connector?

Thanks in advance!

//Sven

I had a nitrous backfire a couple of years ago and it put a very large crack along the bottom of my intake. I sold it to my buddy for $50 and he fixed it with some bad *** epoxy he uses from some of the radiators he would fix. That thing worked like brand new and since it was underneath the intake nobody could tell. Made me wish I would have just done that instead of buying a new one, lol
