I have a 1999 Honda Accord LX. Motor oil is getting into the cooling system. We've changed the head gasket, head bolts, checked the head for leaks and planned it smooth, replaced the radiator, water pump, timing belt, thermostat. IT STILL LEAKS OIL into the cooling system.
Have any suggestions?
Desperate!!

How did you check the head for leaks?

What you're describing pretty much only comes from head or block problems.

If you used a quality head gasket set, such as FEL-PRO, I suspect the machine shop did not do a good job. I did one of these jobs 2 months ago, but knew the quality work done by the machine shop. They specialize in machining and rebuilding heads and have been doing it for years. I assume you followed the correct procedure in torquing the head, which is crucial.

Another possibility is that you did not properly purge the cooling system of air, which resulted in blowing the head gasket again. Check your Owner's Manual for the correct procedure for your Accord. Attention to detail makes a huge difference on aluminum head engines.
