Good picture of how clean the valve is after the head has been rebuilt.Come on how stupid do you think we are budhmm. specifically what engine you talking about or all in general ?
at 100k you can see the valve perfectly clean on a 1.8 toyota

He's trying to suck everybody in,that heads been rebuilt or very well cleaned,but i'm leaning towards rebuilt with new valves,as there's no traces of guide wear on the valve or oil staining on the valve stemMaybe your engine runs clean with zero oil carryover from your PCV? Maybe it has a coalescing PCV, unlike many US cars (cheaper)? How would I know?
Engines that don't have coalescing breathers will develop intake valve deposits. There is no such thing as a zero blowby piston engine.

You behaving,i'm gonna go buy myself a lottery ticketI was going to comment on that, but figured I'd behave myself. For a change.
Don't feel bad,but i for one,don't really put much stock in what you're saying,especially about that head in your picture Why would you pull the head if there's nothing wrong with it,other then to rebuild it.Good try bud,but some of us weren't born yesterdaythe head is not rebuilt. the injector washes the valves. simple as that. theres a light oil film on the runner walls but its harmless. the plenum had oil settled at the bottom. not alot but again ,harmless. for 15yr i would of expected worse but that just isnt what i saw. the pcv is nothing out of the ordinary. certainly not the type that can capture oil vapor.
sorry to disappoint all you 'experts'
Start reading.another thing people fail to realize. in a good running engine we are only talking a medicine drop amount of oil every few miles in each cylinder.
all they see is a 8oz cup at each oil change then freak out.
so much of this stuff is over blown
Apparently you don't like reading,and i'm guessing have never ran a catch can,lol.What comes out of the crankcase coats the throttle body and the inside of the intake manifold,while also dropping the effective octane rating of the fuel you're using.I bet you've never cleaned the throttle body on a Hemi either have you. I'm out,as no matter what you think or say about a catch can(which is wrong ,lol),does nothing to change my mind,or anyone elses mind who is running a catch can.ive gave you photos exactly of what my engine looked like when the manifold came off and you still refuse to believe port injection washes the valves clean. seeing it in your own garage with your own eyes would make no difference to a person such as yourself
Since I never heard of a "catch can" before this thread started, if it's so important of a part why is it not a standard feature on the Hemi?Apparently you don't like reading,and i'm guessing have never ran a catch can,lol.What comes out of the crankcase coats the throttle body and the inside of the intake manifold,while also dropping the effective octane rating of the fuel you're using.I bet you've never cleaned the throttle body on a Hemi either have you.

Little tidbit for you,the Hellcats are port injected and run a factory air/oil seperator(aka a catc can),but they dump the residual back into the oil pan,as Ma Mopar knows the average owner probably won't stay on top of maintaining a seperate stand alone catch can

I'm not going back through 12 pages and sifting through every single response. I know what it's for from reading some of the posts, but going by what I recall from the few times I've looked at this thread I don't recall anyone saying why the Hemi doesn't come with one if it's so important.You ask a lot of questions that you can easily find answers for yourself using your favorite search engine and a little of your own time.

What's the last line of my post that you've high lighted say .Since I never heard of a "catch can" before this thread started, if it's so important of a part why is it not a standard feature on the Hemi?
I guess should have specified, since this is a RAM forum. Why isn't a catch can part of standard equipment on the 5.7 and 6.4 Hemis they put in their trucks? It would simply be like making it part of the standard equipment and add it to the maintenance schedule like changing your oil. Everyone knows they need to change their oil, and based on the posts I've read here it's a simpler procedure to maintain than even that.What's the last line of my post that you've high lighted say .
Air/oil seperators are standard features on the Hellcats. Buy a set of Hellcat valve covers if you want a factory air/oil seperator,but most of us just buy a seperate stand alone catch can,and dump it on a regular basis,way cheaper then the hellcat valve covers

Brother, I'm just going to say it...OK, apparently that was funny to some of you but it was a serious question.
