    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?

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

    Engine oil began leaking into my coolant when the engine was hot. This caused a loss of engine oil and decreased the efficiecy of my cooling system as the problem continued and worsened. I know of no solution except to replace the engine 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
    Carlos

    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?

    The dealership first diagnosed the oil lead as a rear main seal leak. So I spent the money to have it replaced and the oil leak persisted. The dealership then said it was the engine block leaking and that Honda has a recommended fix that uses JB Weld. The dealership performed the recommended fix on two areas on the engine block; neither fixed the issue. So much for having a Honda lasting longer than 155,000 miles; man I feel like an idiot for having thought that.

    Never had problems with my Honda until this - found oil in coolant reservoir, took to shop, they couldn't figure it out, but said most likely blown head gasket, but there was no water in oil. $1200 later and two weeks later, oil back in coolant reservoir, got back $800 of the money I paid them / another mechanic said it had to be oil cooler (attaches to oil filter) - another $550 and 1 week later - oil in coolant again - keeping oil at about a quart low to keep leak from getting faster with more oil pressure / using turkey baster to siphon some of the oil out of top of radiator and cleaning coolant reservoir once a week - checking hoses and radiator cap for deterioration until I can save enough money to buy another car / car is still running good.... only fix is replace engine, but what if that engine has same pourous cylinder problem & transmission goes after getting new engine ????
