I already had the oil cooler removed -via manifold- and pressure tested...I was lucky and it was the oil cooler, it was very corroded.

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.

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

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Hello: My heat exchanger seems to have gone (oil mixing with water) and need to access the oil heat exchanger. Do I have to drop the engine, or can I work my way to it? (removing the manifold, etc??) Has anyone here done this before? Thank you

POST 2Original post

Yes certainly people have done it. Yes you can get to it without removing the engine, and by removing the right hand side intake manifold, or at the very least the a/c compressor. Although the oil cooler can be a source of intermix, cracked heads seem to be a more common reason. If you remove the oil cooler, have it pressure tested to be certain it is the cause for intermix. In addition, the intermix in your system MUST be completely cleaned out, otherwise it will eat away and destroy at the miles of hoses in the car.

POST 3 / ORIGINAL POSTEROriginal post

Great, thank you very much. I will give it a try. I will go for the IMS update as well, is the general consensus to use the LN kit?

POST 4Original post

Have you posted pictures of this car? We like to see pictures before we start handing out free advice.

POST 5 / ORIGINAL POSTEROriginal post

Will do, I will take some pictures once I get to the shop. Thanks by the way for the advice. I already had the oil cooler removed -via manifold- and pressure tested...I was lucky and it was the oil cooler, it was very corroded.

POST 6Original post

You are lucky, glad to hear it wasn't worse. Yes, the LN IMSB kit is the one to use in the US. There are some UK choices as well.

POST 7Original post

You can get it out without taking off the manifold, AC compressor and the center plenum is a must. With the trans out its not bad at all...

POST 8Original post

I need to remove the heat exchanger and will try to hijack this thread. Do you mean that I need to remove the transmission in order to access the center plenum and ultimately the heat exchanger?

POST 9Original post

If your going to do other things as well your much better off to just drop the engine. It isn't hard at all and makes it so much easier to replace all the "while your in there" issues.

POST 10Original post

I'm not planning on doing anything apart from fixing it but I'm not sure what needs fixing at this point. Chances are I'll need to rebuild the engine so you're probably right. Although it is tempting to just remove the heat exchanger and hope that is the cause of oil in the water. What usually causes this in the 911?
