Hyundai Elantra 2005 creamy Sludge in Radaitor No water in Oil?


Asked by Aug 11, 2015 at 06:58 PM about the 2005 Hyundai Elantra GLS Sedan FWD

Question type: Maintenance & Repair

Recently had my head shaved and now I am seeing creamy sludge in radiator but no sign
of water in the oil. This is approximately ten days after repair and car was running great
until today when it died at a light. Immediately restarted and found a hose loose, checked
water and oil and its running again.

Do a Prestone Super Radiator Flush.


I had just put a radiator cleaner flush in before it went down on me and never really got it flushed good. Going to try flushing again, thanks.

White gunk is emulsion. It is a mix of oil and water. (Yes, they really will mix) and it sounds like when the heads were re-installed you now have a blown head gasket. Maybe they got put on upside down or whatever, but it is no coincidence this is happening right after the heads were off then put back on
