    Re: Ad41p

    If you ever find the solution please let us know. One of the stranger faults I have heard of. The key not shutting off could be due to the high fuel flow stopping the shut off valve from sealing?

    Re: Ad41p

    Sounds scary. So the fuel shutoff solenoid is not operating? Does it operate Ok when the engine doesn't do this? I suspect that your injector pump is bad but have no idea what is happening to it. Is...

    Re: Volvo Penta TAMD 22

    I don't know that particular engine but have worked on KAD32's which are also a 4cyl Volvo of probably similar vintage. As far as I can remember the mount for the fuel filter is not connected to the...

    Re: Ad41p

    So the injector pump is set to idle when the engine goes WOT or does it all happen so fast that you haven't been able to check before turning it off? You would expect that either the injector pump is...

    Re: Volvo Penta TAMD 22

    I can not see any way that your turbo can push oil into the fuel system. It has no connection to the fuel system and your fuel system runs outside the block other than maybe the primer pump...

    Re: Ad41p

    Have you checked the position of the lever where the throttle cable goes onto the injector pump?

    Re: Volvo Penta TAMD 22

    How did you confirm that the oil pressure was OK? What rpms were you actually reaching? Are you sure it wasn't the oil filter that was leaking? Can't think how oil gets to the fuel filter without...
  8. Re: kamd300a exhaust elbow leaking raw water in air chamber

    Can you shoot the in and out on the air side of the after cooler and if possible also the water side in & out. Don't worry if it is a problem to shoot them as this probably isn't the issue, but would...
  9. Re: kamd300a exhaust elbow leaking raw water in air chamber

    Did you manage to confirm that the temp at the temp sender unit is the same as on the gauge? All the temps you shot with the IR look pretty good on the engine so the gauge accuracy needs to be...
  10. Re: kamd300a exhaust elbow leaking raw water in air chamber

    If the thermostat housing is reading 150 isn't that where the temperature sender is mounted? I would have expected that reading to match the gauge reading pretty closely. Can you identify the temp...
  11. Re: kamd300a exhaust elbow leaking raw water in air chamber

    What were the input and output readings across all the coolers? Especially the Heat Exchanger? Impeller are usually able to go in both ways but some do have a sealing cap that fits over the centre...

    Re: Battery Isolator

    Out of interest, are your alternators externally regulated to compensate for the isolator diodes? If not there are now 'lossless' isolator products out there that might work better for maintaining...
  13. Re: kamd300a exhaust elbow leaking raw water in air chamber

    Yes around that 190 - 195. It could be inaccurate though so do check by shooting the thermostat housing next to the sender unit. Sorry I don't know that engine well enough to comment on where to fit...
  14. Re: kamd300a exhaust elbow leaking raw water in air chamber

    When you do the infrared gun checks do each end of the aftercooler, then each end of the heat exchanger, plus each end of the thermostat housing (at the hoses if any) then the outside metal of the...

    Re: KAD42 engine knocking

    If you can, use a gas torch to heat them really hot (just the blades) and straighten them yourself with a hammer. They won't be perfect but you can probably get them close enough that you can carry...
  16. Re: kamd300a exhaust elbow leaking raw water in air chamber

    The volvos I have run have all been in the low to mid 180's at cruise and maybe 190 or a bit more at high rpms. I think you should expect to see around 185 or so at cruise, with maybe close to 200 at...

    Re: KAD42 engine knocking

    Thanks for the update. I am glad you got it sorted. Bad news on the props. They are not cheap items unfortunately. Can you get the old ones straightened or are they missing pieces now?
  18. Re: kamd300a exhaust elbow leaking raw water in air chamber

    Didn't you already clean the heat exchanger and intercooler last season? Did you acid wash them or how did you clean them? also is their any oil cooler or fuel cooler in the raw water system that...

    Re: KAD42 engine knocking

    Not something I have ever tried. The cylinder will still get oiled from the crank etc so I guess that it would not seize if running without fuel. So if you can deal with the fuel line you might be...
