Hey all, new here.
I just had new heads and all gaskets (intake manifold, valve covers etc.) replaced as well as the water pump on a 2001 Ranger with a 3.0L with 122,000 miles. Radiator flushed and oil changed. I had a coolant leak at the front of the right head externally, no oil in coolant or coolant in the oil.
3 weeks later and I find a lot of oil in my coolant resevoir. I had been checking it pretty regular for any problems after the fix. Took the truck back to the mechanic and after pressure testing the cylinders and pulling parts off the front of the engine he told me the timing chain cover gasket was bad and the cover was warped causing oil to get in the coolant. There is no coolant in the oil and no smoke coming out of the exhaust. The engine runs perfect other then the oil in the coolant. Is this possible? Could there be a good cylinder test if the leak is between an oil port and coolant port?
I guess the mecanic doesn't have a lot to gain if he fixes this and it still has oil in the coolant so I tend to put some trust in his judgement, but this is getting expensive. Ball Joints are next if this works.
