I was told by the Honda dealer that my Honda has a porous block and the only way to fix it is to replace the engine with a used engine because they can not get a new engine. How do I know the used engine will not have a porous block?

I have had this Honda Accord now for a year and a half, with no problems, never overheated, excellent mileage etc. and 3 weeks ago I discovered a substance resembling molasses in the coolant expansion reservoir, then I opened the radiator cap and discovered more of that substance in the radiator, checked the engine oil level and it dropped closer to the lower dot. I always ensure that the oil level is between the 2 dots
The engine oil is super clean no trace of any coolant, so I am assuming there is a crack in the engine. I constantly monitor the engine oil level and top it off as needed ( approx 1 quart per 1000 kilometers), and I also empty out the expansion bottle into a waste oil container once a week and fill it with fresh coolant .
The upper radiator hose was also replaced because it started to deteriorate.I am not sure what to do to fix the problem, other than replace the engine, what other solution is there ?
thanks

Oil in coolant; head gasket is fine; will require new block.

Told by dealer that engine has bad / porous casting that lets engine oil and coolant mix once the engine heats up. Repair costs ~4000

We just got this car and now, we have oil in the cooling system. I was told I have a "porous" engine block and need to replace the engine. Also, the check engine light is on and I was told that I may need to replace the computer.
I was told "this is a problem car".
This is all adding up to close to $4,000!
I am wondering should I keep this car or trade it for something without so many problems?Flag ThisLike | 1 person likes this1 -

I just recent noticed oil leak on my Honda 2003 Accord Ex V6. I was told by Honda service team that they were not 100% sure until they have to remove the transmission to determine the cause for sure.
With 64K miles and good maintenance record from Honda service. I was told that could be cause by engine block which may cause 5-6k to replace the engine.
I am kind disappointed with the news, but that was my bad luck then...

Rewoeked the head, replaced head gasket, problem only came back after highway driving on a long trip. I can flush the coolant and it is fine for local driving, low speeds.

i paid over 1K to have,and i am not making this up,straub honda in whheling,wv use JB Weld(the approved honda fix for this problem)about one(1) year ago;the problem has reappeared and it is now estimated to be $9669.00 to replace the short block & recondition the head;that has to be at least the current value of the automobile,if not in excess of it;

Oil leak from engine block. Repair shop indicated it is because of a porous block.
