I just did the intake plenum gasket on my 5.9 magnum it has 147,000 miles and I was curious where my camshaft was in the wear world , and I tuned to to your video , easy subscribe .. I’m still not sure where my girl is but tremendously Informative video thanks for taking time out to bring this to us all to learn .
Hey man thanks for explaining clearly in this video 👍🙏💯I just did my valve cover on my 2.5 Lima engine on my 99 ford ranger. I saw one of the lobes had spider cracks but it was otherwise smooth. It looked almost like the metal was manufactured like that?? Wondering what you would guess it is?? The engine is running fine right now I guess I was just curious if it was from previous owner lack of maintenance or bad oil. I know they just used whatever was cheapest non synthetic.
So many people think a technical video has to be done in the shop or an industrial setting.. But such places have very poor acoustics and this video has annoying echoes that make it hard to listen to. An environment with soft furnishings that absorb any echo is a so much better place to record.
Cam break in- If you have to run the engine at 2000 rpm for 20 minutes for the break in to keep keep plenty of oil on the lobes, why doesnt the lack of oiling after break in kill the lobes while idling? I guess I'm not understanding what the break in procedure is for? Does break in make the strength of the metal in the cam greater? If oiling is a problem before break in, isnt it a problem after also?
I would guess the exhaust valve camshaft suffers more than the intake, cause the exhaust valves are under a lot of pressure from the combustion explosion and the camshaft has to press a lot in order to open the valve. Am i right?
Which camshaft sees the most wear? I'd say the intake cam because 2 out of 4 rocker arms broke in half and all lobes are heavily worn in my engine :/ Exhaust cam is totally fine.
Please help me because i dont understand excellent English sir. In my car i have marks only on intake camshaft big lobes (vvlti 2zzge toyota like honda vtec) but with my nail is smooth from side to side! Can survive this camshaft with good oil and quik changes or it has started to wear out anyway? With my nail i dont feel anything!
@KCKLubricants thanks mate! If the camshafts have marks but anything deep is damage? with my nail is very smooth! must I worried or its OK? I mean can a good oil save this cam or wear will continue?
My honda is clicking. Excess oil smoke out the exhaust. Some white. Coolants is ok but extra oil in the cams and spark plugs click increases with speed and rpm seems a little lower 2014 honda accord v6 with vcm.
My mercedes E220 W212 model is showing two blue lines on its number one cam lobe, no other marks or indentations, i am using the correct spec oil and have started using a liqui molly additive, the engine has done 129k looks like something ran hot but why ? I really dont want to get into a cam shaft change or cam follower change.any ideas, Cheshire UK
Thanks for watching, a weak valve spring could cause damage on the back side of the lobe, or even a sticking valve. Definitely something to investigate there.
short answer is, if you need a zinc additive your using the wrong oil. Use a quality oil like KCK which contains enough quality zinc to protect the flat tappets. check this video out on zinc, you might find it interesting. ua-cam.com/video/tlr8fp07Rt8/v-deo.html
Thanks for watching, depending on where the pitting is, could be the lifter bouncing on the camshaft or poor oil causing premature wear to the camshaft
Both oil's definitely have a role, when talking camshaft and valve train it is more dependent on the zinc content and type of zinc in either oil that makes the most different to the 'load' capacity of the oil. This video explains more about zinc ua-cam.com/video/tlr8fp07Rt8/v-deo.html

Excellent presentation. Wish I would have watched it BEFORE I turned my cam into a paperweight!!!!
Your not the first! glad it was helpful.

Thanks for watching! I'm really not sure, that sounds pretty strange. If anyone else has seen this please let us know!
Great video and explanation. Thanks Mat!

Cam break in- If you have to run the engine at 2000 rpm for 20 minutes for the break in to keep keep plenty of oil on the lobes, why doesnt the lack of oiling after break in kill the lobes while idling?

Thanks for watching, the break in process at 2,000RPM has more to do with the lifter seating correctly with the lobes and not so much about oil flow.
I would guess the exhaust valve camshaft suffers more than the intake, cause the exhaust valves are under a lot of pressure from the combustion explosion and the camshaft has to press a lot in order to open the valve. Am i right?
yes you are right, opening against the combustion pressure makes all the difference. Thanks for watching!
Which camshaft sees the most wear? I'd say the intake cam because 2 out of 4 rocker arms broke in half and all lobes are heavily worn in my engine :/ Exhaust cam is totally fine.
Well done! thanks for watching

that sounds like you have some mechanical problems!
😎 great video!!
Thank you very much!
Hey, i have cruze 1.8 2014, it's camshaft hitting the exhaust cam sensor also facing low gas mileage and loss of power, what cause this please help
Thanks for watching! defiantly sounds like you need to get that checked out!

Thanks for watching! any marks on the cam lobes are bad news, are they like scratches or just coloring?
Nice explanation
Thanks for watching!
I have a comp cams custom hydraulic roller cam I have 1 lobe junk on the back side. No idea why

What about suggesting using a zinc additive in a flat tappet camshaft engine?
short answer is, if you need a zinc additive your using the wrong oil. Use a quality oil like KCK which contains enough quality zinc to protect the flat tappets. check this video out on zinc, you might find it interesting.

Thanks for sharing 👍
Thanks for watching!
what about pitting on the camshaft loves
Thanks for watching, depending on where the pitting is, could be the lifter bouncing on the camshaft or poor oil causing premature wear to the camshaft
What about a base 4 synthetic vs conventional oils?

Oi mate good video
Thanks for watching!
What causes cam lobe to wear?
Most of the common causes are covered in this video!
Exhaust camshaft gets more wear
Absolutely!
@relax t your comment won my heart, Because I can observe same with my opened engine.
Both
Thanks for watching!
Always hated those who run their rice burners to the Rev cutout. Might as well take a ball peen hammer to the valve train!
Thanks for watching!
Just run a quality synthetic and change every 20,000 miles.
Thanks for watching, a quality oil makes all the difference!
Exhaust
You are right!
Thanks for replying back , great video enjoyed the in depth, above my pay grade but was glued to it .. well done y’all
@@nadronnocojr thanks for watching
EXHAUST
Correct!
