Yeah I hate when people ask questions but they never post what fixed the problem. The muffler I put on it I don’t like it has a flat plate in the middle of it that the exhaust has to go around. I need to find something different.

I need one like that with a 44” body 4” inlet 5” outlet. The one I put on here last night has a flat plate in the middle of it. You can tell it can’t breathe very good.

No it didn’t I have hunted this problem but I finally found what it was today. The muffler had blown apart and the baffle had shot perfectly straight up was stuck In the exhaust tip. So the whistle noise that i thought was a turbo leak is were the exhaust was passing thru the little holes on the baffle. Not sure what was causing the poof noise but it sure sounded 100%!better after putting a new muffler on it. We will see how it does Tomorrow.

I think I found it this the hose coming off the back of the compressor going to the intake. Only bad part is I am sitting in a parking lot loaded with asphalt. So I hope it holds up till I get in

No I don’t have a wastegate

Checked the exhaust side and rechecked the inlet side of the turbo tonight the fins look good and there is no oil around it

It is cv 713 yeah I am going to figure out how to pressure test it with the smoke. But what ever happened yesterday happened all at one time I heard the pop and after that I had the boost problem.also when it pops you get puff of black smoke out the exhaust. But also the primary filter is only half full of fuel isn’t that supposed to completely full all the time? I also have replaced the fuel lines from the tank to the filter and the filter to the pump.

Especially since it is just a straight turbo no vgt or watergate the only 2 reasons it won’t build boost is either the fins are bad on the exhaust side of the turbo or it has leak somewhere. I hooked a smoke machine to it last night and didn’t see any leaks.

The intake pipe is clean I am going to pull the exhaust side tonight and look at the fins. I had an old mechanic tell me the same thing he thinks that with the turbo not building enough boost fuel might be accumulating in the exhaust and detonating especially it being so intermittent. I have been running the truck for 8 hours so far today and it has only happened 4 times

It looks ok I don’t see any black soot marks around

Yeah I can check that this weekend if the truck doesn’t get any worse and it makes it till then

And the motor seems to run great as long as you keep in under 20 pounds of boost no miss or hesitation in the take off but going from 20-25 pounds of boost you hear a roaring noise coming from under the hood and it won’t go to 30 pounds it stays right at 25.

Not sure what are fuel worms? It has two filters side by side on the left side. It doesn’t have a water separator

It is a Jacob’s Jake brake

I will when I get home tonight. Still trying to figure out were the silicone came from
