Header Collector; How do you keep it sealed?
- Thread starter JPMSK5
- Start date
Have a muffler shop swedge you a piece of tubing to install into the collector that will protrude into the exhasut pipe and tack weld it to the header. This way when the exhaust pipe is bolted to the collector there is still pipe between the header collector and the exhaust pipe and no place for the gasket to blow now. Also the copper gaskets work great if the pipe doesn't sit exactly square to the collector.
If you don't understand i can make a drawing and e-mail it to you.

No, shoot me your e-mail and i'll send you a drawing of what i'm talking about.

He is talking about cutting a 5" (maby) piece of pipe to install in side your header. so that when you mount your exhaust up the exhaust gases will bypass the seal and go right into your exhaust.......Hey thats a new one a pipe within a pipe hahah. Good idea though
That is exactly what i'm talking about.

Guess what I'll be doing next time my gasket goes south.....thanks for the idea.
2 options.
1. cut off the collector and weld pipe straight to it. you don't really need a bolt on collector anyways. this is the cheap option if you already have the headers.
2. get a set of Hedman headers, they have a ball and socket collector. I have a set and love them. this is the more expensive options unless you need new headers.

Got your e-mail. Sending drawing now.
another option not mentioned is to buy yourself a performance collector, weld that to your headers, than you'll have a slip-fit connection for the pipe to slide over, then clamp it.. Thats the method I'll be using...
I haven't had a collector leak since I switched to aluminum gaskets about 2 years ago. I've had that interface apart a few times, too. They're about $15 from Summit. I only wish I could find a solution that good at the other end of the headers...
I used the thick, expensive, multi-layer aluminum gaskets at both the block and collector ends. They seem to seal very well.

Same here. I switched to the super soft aluminum gaskets, and have had no leaks. My O2 sensor is mounted at the collector, so I had to elimimate all leaks. So far so good.
Dont use a gasket, use that Hi Temp copper/orange colored RTV. I think thats Permatex. I have used it for years and never had a leak at the heads. Its messy and you have to put it on a screwdriver first to reach down there in some spots, but get a good 1/4in thick smear around the exhaust holes and put your header straight on and get a couple bolts started to hold it in place. Then you can relax and tighten it all up. Let it sit a couple hours and it will seal the best.

this is also what i used.except i used longer bolts and doubled up the aluminum gasket to make sure it had enough to seal good.i have had no trouble ever since.

i just went to the performance section at my local parts store.i think i just used longer bolts on the engine side on the head.the collector bolts were long enuf to work.deopending on how long yours have been on there,they sometimes break because of rust and corrosion when you try and take them out to replace the gasket.
