All roxors leak boost!

What weighed in...

 

[Roxie19]

Alright, something else to add to the list....

 

[Roxasuras]

The delete was one of the first things I did when I bought it.

I will ordered EGR blocking plates the other day. About to order the intake connection kit & the intake tube

 

[WillysJeep]

Hey Roxie19. I don’t think you need the block off plates if you get the intake pipe from Diesel Freak.

Yeah, I'm realizing that now but whatever, it's done now. Thanks though, I appreciate the heads up.

One other thing to consider. When you take all the stock stuff out you need to get two “caps” to block off the flow of coolant. The reason I know this is I have the exact same parts on order. I asked Jenny the parts person at DF to add them to my order. I think they are $30 which is a lot but at least you won’t have to go hunting for them. Also Wade recommended to drain some coolant, not all but some, because when you take the hoses off it will spill all over.

Great info to have dude, thanks again

Well my Diesel Freak air connection kit finally arrived this week so this morning I tore into the removal of the old along with doing the EGR delete along the same line Roxasuras did in the video in this string. Much to my surprise when I was finally able to start rebuilding it, the new air intake will not go over the tube in the air intake. Has anyone else who purchased this kit run into similar problems? No matter how I spin it, there just is no way it will slide down in place. I am looking for a solution I can use today if there is one, as I was scheduled for the next group ride Sunday but I am feeling that I now won’t be able to attend. If sending it back to DF is the solution, I guess it will have to wait until a Monday when they reopen from the Holiday weekend. Thanks for any advice and tips you can offer.

Which tube are you talking about? Are you referring to the intake manifold itself, or the pipe?

 

[Arizona Johnny]

Yes, it’s the intake manifold. For lack of better words there is a tube rising up from it that the intake that DF sells sits down on with two O rings inside of it. It sits where the factory rubber piece sits that tends to warp, pucker, become out of round and leak boost when under pressure. It appears the quality of the tube in sizing is not always consistent for the DF one size will fit all intake. Wade emailed me and said to try sanding the intake tube down enough to slip it down, but it appears to me there is just too much aluminum material (diameter) to be sanded down. Will give it a try and see what happens.

 

[Colderweather86]

Have you measured the OD of the intake manifold and the ID of the new piece?

 

[Arizona Johnny]

Sanded for quite some time and didn’t make a dent in getting this intake connection piece on. So I brought out the Dremel tool. Went through two aluminum oxide grinding stones and finally trimmed enough material off to slide it on, with the help of a rubber mallet. Not exactly the easy install others have reported, but it’s on and there is a noticeable increase in power. No doubt the factory setup does leak and this piece from DF does a nice job correcting the problem.

Did you lube the o rings? I used a thin coating of lithium grease and mine slid right on for a nice and tight fit.

That would have been nice if it worked out that way. The tube diameter was so large I couldn’t even get to the o rings without shaving a lot of metal away. Just to far out of spec. Guess I was just spoiled from the other change this weekend. Cecco front bumper that bolted right up no problems. Wish Mahindra had his quality control.

Anyone who has installed the DF intake kit (just the stack, not replacement of the "yellow" tube): thoughts on keeping the factory hold down bracket?

The lady at DF I spoke to said the factory hold down bracket is no longer needed with the dual o-ring piece.

I decided to keep it after installing the DF kit (...some of the kit... the mix and match stack in my earlier post).

What did you guys do?

Realize this doesn't directly answer your question, but since I'd bought and installed the after market OTR hold down brackets for my 2018s early on, the cost was sunk and, though hardly necessary and redundant, there seemed to be no harm in leaving them in place after the much improved DF kits became available and installed. On one 2018, the OEM gaskets were not salvaged. The other one's gaskets were perfectly reusable. Both the DF kits fit snuggly without alteration. The yellow tubes remain until I can afford to get rid of them.

 

[Max A.]

I had to modify my factory hold down bracket slightly.

I also can say that the hold down is necessary. At some point my hold down came loose the entire stack blew off the manifold once pressurized.

You think 2020 models might leak boost? Or you think they fixed the issue 2 years into production?

 

[Deuskid]

Anyone know a source for Roxasauras' videos? I'd like to view them

Thanks
