Author Message   Pat Burke New member Username: patfranburke Post Number: 1 Registered: 11-2009 Posted on Friday, November 06, 2009 - 12:56 pm:    See attachment Volvo Volvo.doc (27.6 k) I have changed the turbocharger 4 times which solves the smoking problem for a short time. I have included a detailed summary of my problems and actions. I need help. Please post all suggestions. Thank you, in advance, Pat Burke   Pat Burke New member Username: patfranburke Post Number: 2 Registered: 11-2009 Posted on Wednesday, November 11, 2009 - 08:00 pm:    Second try, I may have overwhelmed the system with 2 pages of problem description. New approach: I have been overprotective with my engines (low RPM for 200 hours) since we found FOD in the ruined turbocharger. Should I accelerate quickly to high power and clear out both engines regardless of black smoke in the exhaust??

I am in San Diego and will travel to Ensenada next week and get the pictures. In the meantime here's a description of the 3 engine air intakes. We have 2 chevron type intakes (3"x14") on the side of the cruiser; we have 2 deck intakes (5"x10")behind and protected by the cabin; and we have 2 more (3"x12") on the transom protected by the bait tanks. I have tried running with both engine room hatches open (4'x8') and the port engine seems to be running normally. Thank You, Pat   Morten Ringvold Senior Member Username: haffiman37 Post Number: 4366 Registered: 04-2006 Posted on Friday, November 13, 2009 - 07:05 pm:    I'll wait for the pics.   Pat Burke Member Username: patfranburke Post Number: 4 Registered: 11-2009 Posted on Tuesday, November 24, 2009 - 10:31 pm:    Morten; I took pictures in Ensenada yesterday. See attached. I ran the boat and measured the following temperatures P&S reservoirs 86 deg F; P&S turbocharger housing 175 deg F; Port turbocharger compressor housing 260 deg F, Stbd 380 deg F. I checked the turbocharged air passages and the intercooler, all clean with a small amount of oil. Is it possible that after the first turbocharger failure that I have an oversized turbo and that I am heating the intake air too high and dont have enogh density for the fuel burn??

However no pics attached?
