Help! Dealer claims camshaft is bad and needs replacement

[Lacostas]

Hello Folks

Unfortunately my engine (Box 2.7 2004) needs repair since cyl 4 lost compression due to a broken lifter spring/broken valve...

The dealer quoted me a whooping $13500 (without labour)

I managed to reduce the cost a lot finding some used and aftermarket parts but the camshafts are harder to find.

Dealer said i need new Camshaft because this one is "damaged" due to this discoloration (attached image) and needs replacement. Any expert here please share your opinion



Thanks as always

Yeah i get that part, its bad, but why he insisted and pointed his finger at that little disoloration ?! That was the main "issue" and its a bit weird.

Once a flat tappet cam begins to wear, it is all over and will fill the entire engine with finely ground metal.

Boy, when I used to work on 944s they pretty much all looked worse than that on every lobe. I think we mostly just lived with it but parts were plentiful on those.
Can a machine shop weld and regrind it?

Yeap i know It’s a damaged cam afterall but is the tiny spot in the red circle the main problem?

Cause I have found few used camshafts on eBay and almost all of them have that kind of dark spot wear on the lobe.

for example i found this one on eBay and seems OK to me, but it also has the dark spots on the lobe.

id be surprised if this cam couldn't be built up and reground, I had my 911 done and it has been perfect for years..
maybe new cams are different.
it was a place in riverside california , but just cant remember the name. If you can find it call them , they might be able to give some advice.

found it .. Web-Cam

give them a call

Thanks for the input but im in EU. I guess ill most probably buy the used camshaft even if it has these black spots on the lobe
