K, let me up to date ya on this situation....I have oil in my coolant, not oil in the oil pan, nothing like that. I have flushed it about 4 times, and seems to come back again. I have tested the head and no leak, such as cracked head or broken head gasket. Car runs good, no smoke of any kind, idles good and doesn't overheat too.
But I have replaced the timingbelt, water pump, starter and redid the head with new oil stems and lapped the new valves too and tested it with no leak.. this was about 3 months ago.
Anyone have any ideas what I've overlooked??

 

How's the transmission fluid look?

 

Manual tranny on this one, I don't have a tranny line to the radiator. Would the oil from the manual tranny leak into the coolant rom another route? Thanks for the feedback, sometimes it takes forever for someone to reply.

 

I don't think so, at least, I've never heard of it. I'll have to try and think of something else.

 

Thanks for the feedbacks, yep this still puzzles me. Im running a radiator flush right now and gonna flush it out again by tomorrow. Then I'll see what it does again. Somewhere I read that if you mix 2 different types of coolant, it can create that effect too. Maybe I did that when I changed the timing belt?

 

Good news! Yesterday I changed my oil and nothing in the pan and when I drained the coolant, it had mostly water in it. Most of the oil is gone from the coolant and I added antifreeze back to the system. Will see what it does this week.
