Outbehindthebarn Posted August 14, 2015 Share Posted August 14, 2015 So my truck is leaking pretty damn bad at the joint pictured below. Bad enough the battery box lid is black. I attempted to heat bolt to remove short section of pipe and couldn't get it to budge. I then turned to BMT archives and found that these manifold parts are scarce and decided I didn't want a catastrophe on my hands..... Is there a doughnut in there that needs replaced or what??????

AZB755V8 Posted August 14, 2015 Share Posted August 14, 2015 There are 2 spiral wound spring seals at at each joint they will be stuck and not move in the slot in the pipe section. They slip into the collar at each end. There is not a lot of tension on them and the collars do wear a grove in them from the seals. All three parts are going to be worn. I don't have a good fix other than having a machine shop turn up a new larger pipe section and slip it in each collar. If you can get the 2 manifold bolts loose the manifold collar pieces will spill around to get the pipe out as well. I just did this thing to mine. Manifold bolts are $22-25 each from Mack and the gasket is $14-15. The only place that would have manifold parts anymore is Dale Francis in Ohio. 440-254-4046. Super helpful Guy. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/41351-e9-exhaust-manifold-leak/#findComment-300070 Share on other sites More sharing options...
BGarofalo Posted August 14, 2015 Share Posted August 14, 2015 Pretty much the norm on e9's. Mack does have availability on some of the parts old stock, but they are expensive. I made up a new cross over and flange on mine. Couldn't justify the hefty price of the Francis headers... Even though I really, really wanted to!

AZB755V8 Posted August 14, 2015 Share Posted August 14, 2015 Mine was not as bad as yours. I loosened the springs up with PP Blaster wire brushed everything and used that runny exhaust sealer and it is holding.I have a lathe and will turn up a new cross over piece the next time increasing the end diameters to close up the worn clearance on the collars and add the spring groves. 8620 steel and about two hours lathe work. I'm a retired Tool Maker and with a little more time than most.I wasn't saying to get Headers but they are real nice. I think he would be the best bet for E9 parts, he had what I needed and fair on price, its just a phone call.. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/41351-e9-exhaust-manifold-leak/#findComment-300133 Share on other sites More sharing options...
genco Posted August 14, 2015 Share Posted August 14, 2015 Been to Dale's shop numerous times. You would not believe the parts he has there. I would give him a call, he fire ringed my heads and replaced factory head bolts with ARP head bolts, added a custom built turbo and tuned the truck. It's probably 900hp and eats anything on the road.

AZB755V8 Posted August 15, 2015 Share Posted August 15, 2015 Make only the 3 inch cross over pipe and no other parts with larger end diameters. The longer pipe to the drivers side was still good for me but both can be made out of a piece of thick wall tubbing/ pipe. I would make the pieces out of steel because cast iron gives me a real headache for a day from the dust but is easier to work with. The clearance between the mating parts is the problem and a tighter fit will stop the leak.I was thinking, for a quick fix the rope graphite seal and sealer that is used in wood burning stove door seals may work. It comes in different sizes, take the pipe out and put a ring of the rope and sealer inside of each collar and reassemble, there is end clearance. The rope would fill that and tighten things up.

MACKTRUCKS4 Posted August 15, 2015 Share Posted August 15, 2015 I had Dale build my turbo and I also picked up the exhaust turbo mount,(which he rebuilds because they often crack and also ware out). He re-bushed all the parts I needed but some are still available from mack but salty. Quote Live every day like it's your last, because one of these days, it will be.

Mack Doctor Jr. Posted September 9, 2015 Share Posted September 9, 2015 For a quick fix I have used a sealer before. It's in the stove area at menards. It comes in a black tube like silicone and you have to spray water on your items you seal and is good for high temps. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/41351-e9-exhaust-manifold-leak/#findComment-303144 Share on other sites More sharing options...

It comes in a black tube like silicone and you have to spray water on your items you seal and is good for high temps.Has else anyone tried the high temp furnace rope and cement with success? I'm thinking it would still need a clamp of some form to hold rope + silicon in place.I am concerned about tearing anything apart for fear of ruining something and/or creating a leak somewhere else. I spoke with Francis, and he said $1200 for complete exhaust parts.... but in the post right behind this one a guy said after he had his worked on it STILL leaked!I tried a cement for exhaust leak repair already.. it blew out 5 miles down the road.

Mack Doctor Jr. Posted September 19, 2015 Share Posted September 19, 2015 The furnace stuff works great. Used it on our pulling semi with a twin turbo set up. The red high temp silicone caught on fire so we used the furnace cement and it never leaked with 85 psi of boost.

Outbehindthebarn Posted October 6, 2015 Author Share Posted October 6, 2015 Well, I decided to try VersaChem "Inferno Metal Repair" to patch the leak at the joint. May not make it out the driveway before blowing out. . . Quote Fun is what they fine you for!My name is Bob Buckman sir,. . . and I hate truckers.

rsb502 Posted October 12, 2015 Share Posted October 12, 2015 Sorry im late to the party here, been busy. I am working on an alternative to the Mack Cast exhaust, Francis headers E9n exhaust conundrum. Im getting all my stuff together to sit down at a spare E9 I have and mock up some tubular exhaust for the E9. Im going to make a set out of steel to try out then use heavy wall stainless for the rest. I probably wont have em done till spring but it was my winter project so thats the whole point,lol. I will try to keep BMT informed as I get them together and hope to have the design done and the first set testing on my RW this winter with more sets to roll out of the garage after I make sure they arent prone to cracking etc. 2 Quote "Any Society that would give up a little LIBERTY to gain a little SECURITY will Deserve Neither and LOSE BOTH" -Benjamin Franklin"If your gonna be STUPID, you gotta be TOUGH" "You cant always get what you want, but if you try sometimes you get what you need" Link to comment https://www.bigmacktrucks.com/topic/41351-e9-exhaust-manifold-leak/#findComment-307229 Share on other sites More sharing options...
Outbehindthebarn Posted November 8, 2015 Author Share Posted November 8, 2015 Well the VersaChem "Inferno Metal Repair" did work..... partly. Where I cleaned the gap well, and managed to force the epoxy deep into the crack it held. Where I kind of half-assed it (on the bottom and back side) it did crack and blow out.So, undeterred, I decided to try Blue Magic I had used something similar before on a turbo outlet joint with success, but discovered they had stopped making it in the USA. Manufacturer sent me to Blue Magic and it is the same stuff.Did a much better job on metal prep and cleaning, and crammed the stuff deep into the crack all the way around. U]I am very impressed with this stuff application-wise. It has fully cured and it looks like its going to work. Time will tell. 2 Quote Fun is what they fine you for!My name is Bob Buckman sir,. . . and I hate truckers.

gearhead204 Posted November 8, 2015 Share Posted November 8, 2015 I used some stuff like that as well before called belzona used it to repair lower counter bores on an old 1693 cat in a 631b scraper that was over 15 years ago and it is still holding also repaired a electrolysis spot on a 3408 block that was leaking coolant onto the cam shaft as far as I know that d8l is still running as well. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/41351-e9-exhaust-manifold-leak/#findComment-310569 Share on other sites More sharing options...
