rod bearings were replaced and that sucker was cleaned out well.

Suggestion
Well, you probably know what you do with a 944 engine when the oil cooler seals fail and the same thing happens: disassemble the engine, clean everything and replace the bearings.
Leading evidence: 'Replace rod bearings' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace bearings' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

If not then just clean up change filter and let her rip.

Suggestion · Original poster
leakdown and a compression test showed no problem all readings were great.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

A friend bought a 3.4L on ebay and is in the process of swapping out his 3.2L. The shop dropped the oil pan and the picture below tells the story. It looks like oil/coolant have been mixing. leakdown and a compression test showed no problem all readings were great. We have no idea how long the engine had been running in this condition but there was no sludge at all in the coolant inlet. (like someone cleaned it before putting it on ebay..
)
is this just a paperweight now?

That did happen to my 944 engine! rod bearings were replaced and that sucker was cleaned out well. I am not sure if the shop that has the engine has ever opened up one of these blocks. I think they have just done entire engine swaps.
Judd I'm depressed... thats my engine guys... its a 02 3.6... its out of a burner so best bet the oil got there because of something (could be a lot of things) melting and letting the coolant into the engine... problem is that there is also a little oil in the coolant... and myself and everyone I can get a hold of today have no idea how this could be possible with perfect leak down and compression numbers...
TIA
Very easily could be a short duration driven engine with infrequent oil changes or leaky oil cooler. Pressurise the crankcase and watch for air in the coolant.
It depends like someone says on allot of things excess heat can bring about moisture there and if it sat along time. Does it smell like antifreeze? If not then just clean up change filter and let her rip.
I have a 3.2 originally out of the car with one of those... this engine has perfect compression and leak down numbers so we can knock out the cracked cylinder...
