cracks in block when the old liners were taken out can you get me an exchange block or a good fix the engein is a hino wo 4c
Hi I will help with your problem Please do not rate until all your questions are answered that way you wont have to pay twice Use reply to expert link.Good morning I'm also certified in block cutting or a machinist,Were are the cracks exactly they allow some cracks at top off block but they cannot go up and down or all the way to a water jacket.If the cracks go to bolt holes then there are inserts that can be installed also were liners sit on block deck we could cut out and install inserts and then the block would be ok.I'm afraid if you get your hands on another block used it would have same issue.The only way to get one is new or rebuilt.I would talk to a local machine shop they can get the inserts and cut the block to install inserts and then use new liners.While the block is still in the chassis so if you have not removed yet I would hold off until you know.Don't forget to let me know were the cracks are or pictures and I could give you further info.

I think I uderstand but just to make sure is there any way to take pictures or fax pictures if you contact customer support they can help you I need to see the cracks to give my honest opinion.On the cracks if the cracks are just under the liner flange and don't go beyond the flange area [meaning don't go down or sideways to bolt holes and or coolant passages then it would be ok but without seeing them I can't tell you for sure.I don't know were you are located what needs to be done is magnafluxed the area of cracks and it will show how far the cracks go some times the crack will keep going and you won't be able to see with your naked eye so it is important to know before going further.If you give me your location I can help you find some one to check the cracks.
the cracks are half waydown the block in 2 3and 4 circular not seen by eye but under water pressure . can we make small grind marks in block and fill with devcon or some other substance
my question is the cracks do they start from the top off block were the liners sit and then go down the block into the area off were your coolant is?
Hi did you have a question for me?
i have told you the cracks are half way down the bore in a circular shape going round the bore like a letter c only shorter than a letter c you can not see the cracks unless you water blast the water jacket under pressure ,i ask you can we grind the cracks with a grinder and fill the cracks with devcon or some other agent you might suggest hope you can understand what i am saying as this is the third time i have asked you the question let me know what you think please and then i will rate u
I understand but your asking me to make a decimation for you and I keep asking for info and your not giving me the info I need to make a decision.Let me say this if you have cracks in lower water jacket area you don't have to do anything no devcon nothing they are normal fatigue cracks.But if the cracks go up to top off deck were the liner flange sits on top off block then they would need to have inserts in it.Does that explain it better I do want to help you but I'm giving you my professional opinion and I want to be sure I give you the correct answer please understand I"m trying to help you.
