    Sorry, my "sample" did not come though as clear as expected. Better get a manual!

    Re: hard starting 5.7 2003 crusader mpi

    If it will not start unless you crack the throttle is sounds like the IAC valve (idle air control) is not adjusting. Question is has the valve failed or is it not being told correctly what to do. ...

    Re: Getting closer on the coolant leak

    I had to put it together today. No more time available. I got to thinking that when I have used the graphite gaskets dry, when they went on clean shiny metal they pretty much "welded" themselves...

    Re: Getting closer on the coolant leak

    Hi Mark,
    Doesn't look like I can find what I need to presurize the manifold, but I should be able to seal it up and fill with water to check for leaks overnight. I am making my blocking plate now...

    Re: Getting closer on the coolant leak

    Hi Mark,

    It looks like only you and I have any interest in this thread so I thought I would bring you up to date on the latest, and on my confusion. I pulled the elbow and found plenty of...

    Getting closer on the coolant leak

    Boat has been sitting dry for several months. I came down to find the ongoing coolant leak, which, as discussed in previous posts, I thought for sure would be the heat exchanger. Pressure tested...

    Re: 1996 454 Crusader XL TBI Stalling Issue

    So did you swap the TBI and the problem went away, or did it move to the other engine? Or did you swap, fix/clean something during the swap and then it went away? I have fixed a lot of things by...

    Re: 1996 454 Crusader XL TBI Stalling Issue

    You must be close to finding it.....or not. I mean it is a boat.

    Still thinking about the 10-15 second delay before shutdown and what could cause it. Mako knows these distributors and could...

    Re: 1996 454 Crusader XL TBI Stalling Issue

    The ECU does not know the fuel pressure (pressure is controlled by the pump and a pressure regulator). It only knows what it should be, and it knows what signals it sent to the fuel injector(s). ...

    Thanks for the tip. I will bring down a 17 cal brush in case leaks in the tubes prove to be the problem.

    Re: Heat Exchanger Repair

    Mark,

    Thanks for the response. There was not evident corrosion when I last looked inside so I doubted I had a leak until I remembered the attempt to braze. I agree he did not know what he was...

    I tried to explain what I would try to do and asked if anyone knowledgable had suggestions. Obviously I am not sure it will work. You say you could fix it. Could you share how you might...

    Heat Exchanger Repair

    I have twin 2002 Captain's choice 5.7 engines. The port side has had the “missing coolant” symptom for a year or more that has varied in intensity but is getting worse. Nothing in the bilge or oil. I...

    Re: 1999 Crusader 454

    Normally one can get the manifold off and back on without pulling the engine. But it is a question of access and that is a function of the boat. Your mechanic should be able to tell you at a glance....

    Sure you can use both dipsticks. I just average mine. As for too much oil....you are beyond my experience. Others may chime in with some observations. Logic would suggest you could get some...

    Re: 5.7L MPI Oil Pressure Drops

    Same reading on both gauges suggests the drop may be real. Sounds like it could be low oil level (at high rpms the oil does not drain down fast enough to keep the sump level above the pickup), Is...

    Re: Leakdown test on a 5.7

    OK, sounds safer than having someone try to hold it in place with a breaker bar. Now, knowing you are at TDC without going past it will be a trick. Some sources say never turn the engine backwards,...
