Heat exchanger repair

[Beneteau381]

That's rather insulting as I don't know anything about brain surgery and little about chemistry but having spent over 50 years doing all kinds of engineering design and manufacture including professional engineering training and qualifications. This also included electrical and electronic control systems.

I don't comment on things I don't know about or that someone else as commented on so I have nothing to add.

The point is I know what I do know but also know what I don't know.

If you think differently well that your problem not mine.

Bit touchy?

All comments have been very helpful, even those with tongue lodged in cheek , so thank you all and I hope you all had a good festive period.

Any thoughts on how to best remove the carbon deposits from the exhaust gas chamber?

If you talking about the bit upstream on the valve then turn the engine over by hand i till the valve is closed, use a pipe cleaner type wire brush (brass is better unless super stubborn) then blow out with air or blow out With air and hoover at the same time.

The carbon must not drop into the cylinder or you will have big problems. If your not sure don’t it’s will likely be fine.

It's not about being touchy its that I cannot comprehend why people find it necessary to try to put people down. The only conclusion I can some to i its some personal gratification.

I do get pleasure from helping people but I know I don't have all the answers but many years experience in what I have done.

Unfortunately of late adverse comments by various members have caused other knowledgeable and experienced to leave the forum and go elsewhere.

This is a great loss to the less experienced forum members and their loss.

Sigh! "I cannot comprehend why people find it necessary to try to post on everything!. The only conclusion I can some to i its some personal gratification."
Think about it.

Gentle poking and prodding,

Gentle poking, prodding, scraping and compressed air to blow the bits out. Best to turn the engine over till the cylinder area you are working on, the piston is at tdc with both valves closed.

Again another incorrect assumption. I only post when I have something to contribute to the OP's question.

The last post in this thread by the OP is a case in point with regard to cleaning out the exhaust and maybe the manifold.
jwfrary posted what the OP needed to do and I felt the OP had all the info he needed from jwfrary input even through I had done was was recommended many time when I was tuning engines.

You did chose to post, which is your right but in that accusing of posting on everything which I don't but you chose to make false generalizations

The only conclusion I can some to i its some personal gratification."

As I said I do get pleasure from helping people and most are thankful as I am when I get help. If people don't want my help so be it I don't have an issue its when I or anyone who tries to help but gets ridicule and make a mockery of their endeavours just because it's different to their approach.

Think about it.

I do, and still think there is too much negative and unhelpful comments not only on this forum but in life in general.

Some is about self promotion to personal gain other is about ego .

 

[MagicalArmchair]

Firstly, thank you both for your input, to add to that...



Guess, as boaters, we are not famous at getting along... "STARBOARD!!"... I'll go get my winch handle to waggle with menaces...

The carbon I was referring to was the bit in the heat exchanger, to get it all lovely and cleaned up before it goes back on. Having a poke with a screwdriver and a rub with a wire brush seems like the consensus - no 'soak it in X' solution .

Thanks all - the engineers tell me tomorrow they should have it ready... gaskets won't be with me until the first week of Jan though, dang it.

 

[rogerthebodger]

If its just in the heat exchanger I generally use a small rotary wire brush in a drill. Maybe with an extension shaft to get all the way down the exit point.

I would not expect to see much carbon all the way down the manifold section as the gasses at that point are cool so would not deposit much carbon.

I don't really get upset by people taking issue with ne as I have had this most of my life so have become immune. If putting any less experienced boaters I feel sorry for.

Thanks for the leama pick one of the nicest chilled primate you will find.

Totally agree! - but unless it’s significantly blocked I would put the kettle or break out the scotch and get the dominoes out!

Safe sailing.

Now that ia a plan. Can I pop round and join you.

 

[MagicalArmchair]

Roger that I'll peer in there and then ignore unless significant! The gasket surface on the block could do with some cleaning up as it has some rust and residue on it, so I'll use a razor blade, some degreaser and a brass wire brush to clean it all up. Fine wire brush on a Dremel a good call too?

Littlest was helping me clean it all up today and rust treat some tiny bits.

Great job.

Roger, you'd be on shaky ground there with the female engineers and self-sufficient sailors I know! ?

You can take it that both my wife and myself are very proud of what she has achieved.

I have met lots of female engineers and applaud them in their endeavours and in fact anyone male or female who are creative what ever their field of creativity is.

If you told my daughters that you would be hoisted by your own petard! Times have changed and sexist nonsense like that has no place in our brave new world as severel dinosaurs working in the oil industry and academia have found out to their cost!

My daughter knows me very well and as she one worked for me writing computer programs she also knows I would never force her to do anything she would not like not that she would anyway. A very independant my daughter is.

You are right times have change i parts but not in other. We have 2 pandemics in South Africa 1 being Covid 19 and the other Gender based Violence. With the Rape and murder of women a blight on our society.

My basic phonicity is to treat all people as individuals this applies to White, Black, Blue and Green people alike. Also no matter what the sex or sexual orentation of the person concerned.

I an aware of my own strengths and weaknesses so I don't get intimidated by other people male or female.

In fact I encourage everyone to pursue what they wish and to take advantage of the skills and talents.

If people who seem to be intimidated but others skills, talents and knowledge. I am also appreciative of help from other people and always show it as it can pay back a lot more than it costs. A simple thank you can buy more than it costs next time.

Your post intimated that girls cant help daddy do maintenance but boys can.

 

[rogerthebodger]

Your post intimated that girls cant help daddy do maintenance but boys can.

Yet more incorrect assumptions.

I can remember when Our Daughter inherited my wife's car, wife's choice, daughter had a flat tyre and phoned for help. We went over and I made our Daughter change the wheel for the spare WITHOUT MY ASSISTANCE just advice. This became a teaching excise so she could do it herself next time.

Oh she can do whatever maintenance she wished with or without my help. If she asks for help I will gladly help but Insist on her being there to see have it done so she can do whatever needs to be done.

Daughter is over 40 and an independent career woman now so I would not consider telling her what to do even if she did listen which I doubt

Do you force your children to do anything they don't wish.

Now steady on there - I spent most of my youth being forced to go sailing . I attribute much of my love today to stockholm syndrome . As is the natural order of things, I pay it forward to my children, who now in turn love it also (once prised away from the Playstation!...(Okay, so we do now sail with a Nintendo Switch also...)). And yup, my daughter is just as interested in the servicing of the engine and all the other practical wonders of boat work (who wouldn't love sticking their (gloved) fingers in sikaflex?...)...
