Ill start with removing the oil cooler and checking for internal mixing, since there is no external leaking (seems that rubber seals are "fine").

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hello Folks! Long time no see Problem has already been discussed here quite some times, strong presence of mayonnaise inside the coolant . Ill start with removing the oil cooler and checking for internal mixing, since there is no external leaking (seems that rubber seals are "fine"). The question is - can this be done without draining the coolant ? Eventually ill drain it - and change oil too - but can i just remove and test the cooler prior to the drain ? Regards

POST 2Original post

Yes. It will be a little messy, but you have intermix already. You can minimize the mess by lowering the level of coolant in the expansion tank. I've used a turkey baster for that (do not use it for basting turkey afterward). In most cases of intermix the problem will turn out to be a cracked head, especially in 2000 models. I actually did have one that was bad O-rings on the oil cooler though. Hoping for the best.

Thanks for the fast reply! Okay - ill try to lower the coolant level somehow before trying. In any case, ill take the chances and proceed with it as it. My model is a 2004 2.7L one. Lets hope for the best In case there is a cracked head, any cost estimation available ?
