I tried to put on the oringal silencer cuz I'm thinking the isr is killing my gas mileage, but now I can't cuz the pipe shrunk too much. What can I do?

 

I had exactly what Christian has up in the very top of this thread.
If you go up a few posts you'll see a link that he posted for a fix.

Here's the link:

I think I had warpage because of the overtightening.
That and I have a 150 mile round trip drive to see my girlfriend that I make 1-2 times a week.

 

It shrank? Is that possible?

 

Use properly sized hose clamps from the auto store on all ISR plugs. I apologize if this has caused anyone inconvenience. I feel bad.

The stock clamps just were not designed to apply even pressure on slightly smaller diameter PVC plugs. It simply distorts them over time.

I am here to assist if anyone has any questions.

 

Well, I have to say I appreciate you bringing this minor thing to our attention as soon as you did.

I'm surprised at how little time it took for mine to warp! I probably wouldn't have noticed until I did something seriously bad to my engine.

Out of curiosity though - with the plug being warped would that have affected my mileage? I was noticing poorer than usual mileage until last week. I figured it might have been my driving (maybe more aggressive than usual).

Anyhow thanks again for the heads up!
Trust me - your ISR cap is much better than the version I had before (muy ghetto).

 

Try a Gatorade cap with C02 barbed fittings from a Soda Fountain.

Beat that!

 

Rubber grommet that fit into a plastic cap. The cap went OVER the intake lip (literally a cap).
The 3/4 OD fuel line was a snug fit into the grommet and I used (at first) non-sensor safe silicone sealant. I think I emptied out like 1/2 a tube

After my check engine light I pulled the EFI and coated everything with sensor safe stuff.

I think you did a professional looking job with ghetto parts.

lol u ppl are weird.....and ghetto.

So any idea on how to get my stock silencer back on?

 

I really don't understand how it could shrink... all I can offer is maybe just using a real light coat of some kind of tacky grease or something.

I really couldn't tell you though.

 

Rob-

Are you trying to put it back on with a hose clamp in place?

Many times the hose clamp needs to be loosened nearly all the way.

Another way of asking this question: Will the original silencer box fit without a hose clamp in place?
