Volvo Vnl turbo clamp clocking boost leak fix 

The turbos last usually on these for about 1.1 to 1.2 million from what I've seen

Full boost on mine is around 34psi

Possibly one EGR is stuck open. Mine was similar to that. It would take a min or so an power would cut an then cut back on but felt like I had no power.

Also check boost sensor

@@WhiteGuysWRX deleted Egr ,seen this with check engine light took to mechanic again he cleared all code Nd light

@@WhiteGuysWRX replace abt 2 month but its aftermarket

@@sankahaji8469 possibly that is clogged up. Easiest to check. Remove the sensor an see if it is clogged with black soot. If it is clean check egrs. Take one off at a time and they should be in closed position when truck is turned off and cold after sitting overnight. Check fuel filters also. Make sure right fuel filters and are not old. Old fuel filters can cripple these trucks and make no power

Clamp for egrs?

@@WhiteGuysWRX no the turbo clamp to clock it, i found my boost leak there

@@WilliamGemstone can remove the front of the turbo without removing the EGRS yes. It’s a tight fit. But yes

@@WhiteGuysWRX ok thanks 🙏

@@WilliamGemstone always bro let me know if you need help, that gmail is Cummins part… call an verify in stock before removing…. Huge Cummins part shortage right now

Potentially a boost leak. Grab a spray bottle an fill with 3-6oz soap an the rest water, shake it once lids on an start spraying when truck is cool an at idle. Check all boost related pipes an around turbo.

@@WhiteGuysWRX thanks man I'm post a video of it soon

I believe my problem is the clamp on the exhaust turbo side when sprayed with soapy water blow the soapy water away

@@WAYNE8458 it is a possibility, that clamp does leak an I usually put new clamp on mine an new nut and bolt when I take it off. I would check the turbo inlet also. The little adaptor peace with the two big O rings inside it. Those orings are maybe $5 each and should be replaced. It is easy to clock it while using something like wd-40 to lube the orings while putting them on. Check the angle of the pipe also, make sure it's similar to mine. The pipe that comes from bottom of intercooler to the bottom of turbo inlet

Thanks I do have a little play in those
