Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

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.

POST 1 / ORIGINAL POSTEROriginal post

Last year I had an engine failure at the crank of a 3.4 engine in my Boxster track car. The engine had approx 2500 miles or so since a rebuild by the PO. After the failure, I dismantled the engine and indeed found a fresh rebuild and don't know exactly why the #6 rod failed to be oiled and burned up and broke. That being said, the heads have been inspected and 3 bent valves have been replaced. I also had the frost plugs removed and replaced with threaded plugs. The heads were inspected and found to have perfect seats and guides. All valves looked brand new, which concurs with the PO statements at the time of sale. My question is what are the heads worth, as I plan to sell them complete with cams, and all variocam and supplemental oiling components. They will be bolt on ready. Thanks for the feedback.

POST 3 / ORIGINAL POSTEROriginal post

Interesting. I see cores selling for 1000 bucks each. Machining heads and installing valves and guides is certainly more than $1000 for the pair. I think the 3K is on the low end of fair. But, thank you for your reply.

POST 4Original post

Here is one example of reconditioned heads . Like anything else price can vary . Also different areas of the country the price can be quite different . Hopefully you get whatever price you want for them . https://www.ebay.com/itm/195865153348?mkevt=1&mkpid=2&emsid=e90001.m162181.l175008&plmtId=700008&mesgId=3024&mkcid=8&ch=osgood&bu=43208014395&trkId=153c15fa-fe6c-41e9-b720-48b623a3ac33&cnvId=700003&recoId=195865153348&recoPos=1

Thank you Rfuerst911sc!! I know these are Boxster 2.7 and not 911 3.4’s, but your point is taken. Thanks for taking the time to reply.
