Rb25Det Gooey Oil

[blugtst33]

Hey guys, bought a r33 from a friend.he said it was a head gasket problem so i got a mechanic to change a head gasket aswell timingbelt plus water pump at the same time. After the parts were replaced, there is a place or something still leaking water/fluid into the oil. The head was machined when it was off the blocked.

Radiator is losing water and going into the oil. Did a oil flush and oil was all gooey and thick liked paint. It drained out like 10 litres of crap and took an hour to fully drain.

Mechanic said the water line near the sump or something like that has been repaired? So i did the chemiweld twice.

Probs best option is to replace the motor. How ever money is an issue for a new motor so i am maybe thinking of selling it.

Just want to know what do you guys think before i do anything. So the moment its sitting in the backyard.

It could be the heat exchanger near the oil filter. bypass the coolant lines from it and see what happens.

What superben said or it could be a cracked head. Was the head crack tested when the head gasket was done?

Chemweld is rubbish. Don't use that shit. As both above have suggested water is getting in from somewhere not the headgasket which is either A a cracked head or B the oil warmer/cooler below the oil filter.

Chemiweld

what excactily did you chemiweld?

[WMDC35]

as above, only use chemiweld if you car is a $500 POS which you're trying to keep running for a bit longer before you get it scrapped

I would say being a 25 with an ali head, ya mate prob over heated it and warped the head or cracked as stated above causing your water in oil affect. This is not uncommon, I have had my head off twice now on my 25neo!

Why didnt the mechanic get the head inspected when he took it off to replace the gasket? That's the one thing he should have done when replacing the head gasket due to oil/water mixture. Block the hoses off with clamps or something to the oil cooler and pressure test the system. If there's a pressure drop then it isnt your cooler and most likely the head. In this particular situation.
