eaglescout526 Posted August 2, 2020 Share Posted August 2, 2020 Alright everyone. At the drive in and noticed a rich smell to charge up the battery for the next film. Poked under the hood and found that my exhaust to air box hose is ripped right at the exhaust pipe. Have any of y’all run into this issue and what did you do to fix/replace? Side note, if anyone has a spare one PM me. Link to comment Share on other sites More sharing options...

I don’t think the vac system for my pre heater works but nonetheless it’s still putting out fumes rather than recycle back into the intake.

Big Dan Posted August 2, 2020 Share Posted August 2, 2020 I used a 3 inch diameter hose from McMaster carr. It held up well and was still good to go, after 3 years, before I sold that MJ. Sent from my Pixel 2 XL using Tapatalk Link to comment Share on other sites More sharing options...

Big Dan Posted August 2, 2020 Share Posted August 2, 2020 Yes, I put hose clamps on both ends to ensure a good sealSent from my Pixel 2 XL using Tapatalk Link to comment Share on other sites More sharing options...

fiatslug87 Posted August 2, 2020 Share Posted August 2, 2020 The preheat hose does not have any exhaust gasses running through it. It's simply a hose that funnels heat from around the exhaust manifold to the air box. Link to comment Share on other sites More sharing options...

So far I’m probably wrong and my hand was playing tricks on me as I stuck my hand by the hose to see if I could feel anything and I thought I did but I probably didn’t. I have a spare manifold I’m going to look at tomorrow and see. I'm probably thinking about how older cars recycle the fumes from the valve cover to the air intake.

WahooSteeler Posted August 2, 2020 Share Posted August 2, 2020 This is an aftermarket manifold but still you can see it's just a pressed on hose connector, no opening from the manifold. Link to comment Share on other sites More sharing options...
Big Dan Posted August 2, 2020 Share Posted August 2, 2020 Yep, it's just heat distribution Sent from my Pixel 2 XL using Tapatalk Link to comment Share on other sites More sharing options...
eaglescout526 Posted August 2, 2020 Author Share Posted August 2, 2020 Yeah i went and looked at my spare manifold and saw the same thing. I’ll just leave the hose alone and not think much about it. ‘‘Twas a part I never really looked at till the hose ripped. Link to comment Share on other sites More sharing options...
silvertwinkiehobo Posted August 4, 2020 Share Posted August 4, 2020 If it blew exhaust, you have an exhaust leak, and you don't want the engine ingesting that air when cold. Remove the box end, and start it cold but don't drive it. If it cold idles better, it may be ingesting exhaust at cold idle. Link to comment Share on other sites More sharing options...
