I hope it turns out to be that simple, but I don’t like it. But wouldn’t a breech there only result in coolant entering the transmission coolant line due to the pressure differential, or would it cross contaminate? And if they did cross contaminate, would the contaminated coolant look more red than black if it were transmission fluid in the coolant? Maybe not - what color do you get when you mix red trans fluid with green coolant? I’d guess an indistinct ugly brownish. One potential explanation is contamination from a damaged transmission cooler in the radiator if it has one. Tomorrow we’ll put drops of each fluid on separate pieces of white paper towel to better see the color. The coolant in the overflow reservoir evidently leaves a black coating on the plastic surface of the bottle. The oil and the transmission fluid each seem ok based on dipstick observations, though that may not be a convincing way to judge.
#2000 HONDA ACCORD OIL IN COOLANT CRACKED#
Is this porous engine really another way of saying cracked head, or cracked block? The mechanic has not yet examined the car after the head gasket replacement, and has not yet rendered an opinion. That sounds bogus to me, but all these people reported the same thing - ie, NO head gasket problem. The explanation given in most of those cases was what evidently has a name: “porous engine block”. Some internet research that I didn’t conduct revealed a pattern - many reports of exactly the same problem, that is, 98 and 99 4 cylinder Honda Accords with oil in coolant and no problem with HG. But it has at least been drained and refilled, maybe “flushed”…I just don’t know yet. I don’t have details on how much effort was put into cleaning the cooling system, or how much effort it takes to get the system clear of oil if that’s even the problem. Now, with a new head gasket, the coolant seems to show the same problem, though there’s some speculation that what has reappeared may be residual contamination after having the cooling system drained and refilled.
He suspected the head gasket, but when he pulled the head, he didn’t find any obvious explanation for the contaminated coolant. Her regular mechanic, a very good friend of hers, is a Honda dealership mechanic but does some of her repairs as a favor. My friend’s Honda had oil in the coolant. Thank you.1998 Honda Accord Coupe, 4 cyl ULEV V-TEC / SOHC.
If this answer has helped please click click "ACCEPT" we can still converse after you accept. Here in California you do not pay for repairs that do not fix your car. Reimbursement for any previous repairs falls on local laws. I would recommend you seek assistance from the shop the performed the previous work and see if they will replace the engine with a used one at no cost for labor you will be responsible for the parts. Repairs of this nature at that mileage just should not be performed. The fact is that you have an all aluminum engine. In most cases a used motor with less mileage is more cost effective then the head gasket replacement. Normally on this vehicle at this mileage most shops would recommend replacing the motor not just the head gaskets. Although the head gaskets were replaced and the heads resurfaced chances are that the deck or block is warped. Well I am sorry to inform you but the only way to get oil into the cooling system besides opening the radiator cap and pouring it in, is through the head gaskets.
