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.

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

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

POST 1 / ORIGINAL POSTEROriginal post

Did they replace the engine or merely fix it!!

POST 2Original post

I am not a 996 owner as of yet. I have heard of this problem in the 1999 cars. My mechanic tells me if I buy a 99 to be sure that it has had the engine replaced. You will need to have all documented services on this. Does your coolent dissapear and not leak and you constantualy add more? I believe porsche will replace the engine. This is what I have heard, but don't quote me on this, since this doesn't apply to me. I am sure other owners will speak on this matter. I would love to hear more on this subject, since I will only be able to swing a 99 once I sell my 81.

POST 3Original post

POST 4Original post

Sounds like a head gasket or other problem- your modded ECU or headers could cause you warranty grief . PCNA could claim that thermal properties of engine were affected by either mod.

POST 6Original post

Didn't the recent Excellence have something on this re: the Boxsters? It was some sort of oil/water separator that was failing. You might check this out before assuming it's a blown head gasket.

POST 7Original post

I just had this problem and Porsche replaced the engine under my Porsche extended warranty. I was a little surprised. I had 33K miles on the car - and never had an RMS problem. Oh well - Now I have a new engine. - Bill

POST 8Original post

I did not mean to imply that my problem was an RMS problem. I just mentioned that I have never had one. My engine was replaced because of the oil/coolant mixing problem mentioned by the original poster. - Bill
