Oil in coolant in a 95 2.8D
Posted: Mon Jul 04, 2011 7:57 pm
My guy from across the street from me come running over today as I got home from work for me to have a look at his Lux (95 SR5 duel cab 2.8D) It is 100% on road lux and never really leaves town so its not lived a hard life. Engine has 380ks on it. At 300ks the head was replaced ( I don't know why) by a toyota dealer. Has not missed a beat since and the oil has been changed since new every 10000 ks or 12 months. Last oil change was a little over 2 months ago. Checked all fluids at this time and coolant was fine.
In my 12 yrs of working on cars I have seen my fair share of coolant and oil mixing for a number of different reason but I have never seen this.
He drove to and from work today (10ks away) got home shut it down. No oil to be seen anywhere near where it was at this time. 1 hour after getting home he started it up and moved it to the back yard to load up some wood for his mum. He left it running when loading it up (15 mins) then drove it back out the front. When he got out and walked back to shut the gate to find a huge black trail of oil. Looked all over the engine to find no oil leaks around the engine bay. The oil was over flowing from the reservoir tank and running out from behind the headlight.
Now I have seen plenty of oil filled coolant systems but they always seem the make the oil in the coolant go grey/brown this is pure black and he checked the fluid levels 2 days ago and they were all fine. It isn't mixed in at all (I know oil and coolant will not completely mix but you know what I mean)
Now the engine is still running great. It is not blowing any smoke.
I spoke to a mate that has worked for Toyota as a mechanic for 10 yrs and he said he has only seen something like this one other time and it was a cracked cylinder wall.
I was going to start and hope and cross my fingers with a oils cooler re-seal but hmmmm yahhhh.....
Let me know what you have come across and should I stop wasting time and pull the head.
