Assume I measure the amount of fuel that is going into the engine.  However, not all of that fuel is used.  Some of it is returned to the fuel tank... so how do I know how much fuel the engine is _actually_ using.  Is there a system that measures both of those values and can determine how much fuel is actually used?

Been told I can braze the area to seal up the leak and was wondering if anyone had any idea what the rad from a 1999 Isuzu 3KC1 would be made out of (copper/brass?)? Trying to figure out what kind of rods to get for brazing.

 Thanks!

And a supplementary question; I am on the hard with little access to water.   With the raw water impeller out of the raw water pump, can i test run the engine for 10 seconds or so?  I cannot see why not, but who am I not to ask the question on this forum.

I need to replace the starter on a Yanmar 3JH2 engine in a very tight engine compartment.

Does anyone have suggestions on how to do this without having to remove the entire engine?

Thanks

 I need to find  good mechanic to come and rescue me from my own DIY incompetence.  Does anybody have a recommendation for a mechanic in the Vancouver area?  Westerbeke people would be nice, but right now I have a generic problem that any mechanic can fix.

 

Thanks!

I want to wash the engine down to reduce the smell of diesel.

When the engine has been serviced over the years fuel has been spilled and when the jets have been 'cracked' to let the air out diesel has been spilled on the engine.

I feel if I spray a de-greaser on it then wash it down I will reduce the smell.

What should I use?

Any favourite degreasers and any pit falls to avoid?

 

Bill
