No smoke
Only symptom is power loss and little rough idle

Fyi. I had these injectors to local bosch workshop for new nozzles. Also filters are new and air leaks in fuel system are checked, i did all this early in the season because i had rough idle and hard to start. This was fixed with new pre fuel pump and i found one fuel hose connection that was loose?...

Now i have sort of same problem with pre. Working engine I would say i have about 80% of total power I have to push down gas almost to bottom for getting 3200rpm. I have looked at this a couple of times because i was thinking about air leak between turbo and air intake but this all is ok I found tha...

faulty injectors caused this. switched them between the 2 engines and power back. i had these to 3 different bosch workshops for test, none found them faulty? did buy 6 new ones to the faulty engine. now i ordered new nozzles to the other engine, from (competitor's name removed by moderator). has an...

Have the mechanical lifters been adjusted lately? I'd still like to see clear lines between the injectors and at least a piece of clear line going back to the tank. It can tell things about the injectors and pump, just at a glance. No i have never adjusted lifters. Checked the gap in beginning of s...

Volvo workshop manual says 25 bar. This is little strange with resulta we got About camshaft timing Both inlet and exhaust valves where spring pressurised without lifter pressure when leakdown test . The cam timing has no adjustment Hard to believe valves are leaking with 27bar compression, but mayb...

flow restriction... that can be confirmed with the defect injectors i do not know what was wrong with those, but after i got them back from bosch workshow engine got even worse preformance. now mounted brand new injectors and engine does max 3200rpm i gear. takes longer time to get up to this rpm co...

Fatmobile You must have missunderstand me! We increased fuel anount Then after about 2 hour running engine stopped Opened pipes to injectors and only fuel to cyl nr3 when run starter. Thats about the pump! Update We switched injectors between engines After that little more power ! And other engine l...

I mean fuel miced with airbubbles Still no stop in return Has anyone of you heard of this pumphead gettong stuck? Running dry most UN-likely... Inlet to the high-pressure section is at the top of the pump, above most of the rotating parts. https://dl.dropbox.com/s/ftmbrrqkx7zabt3/Waterline1.png The ...

yes engine has mechanical liftpump and fuelsystem is pressurised after the pump. so not possible to be air in pressure side i have not tested pressure with gauge. but there is both lots of pressure and lots of fuel when opening banjobolts on pressure side. i have now visited bosch workshop. the pump...
