Cam Phaser/Engine Failure Reports

[RMB_Ryan]

To RMB Ryan. I’m in hot n humid like hell south Florida. What weight oil would you suggest ? Ive been running amsoil signature series 5w30. And there top oil filter. My trucks a 2017 and use 93oc always. I don’t cheap out on oil but I’m curious about the monolec. If you could and have time could you make a quick list of suggestions?

The oil I mentioned monolec is what I replaced amsoil with and it crushed it in like all I think analysis that we’re all over with low high mileage big or stock turbos etc.

There are a lot of Honda and Toyota V6s running around in cars, trucks and outboard engines with variable valve timing and ridiculously long service lives.

Ford went with a hollow cam shafts and smaller phasers to save on rotating mass. That lighter assembly will have more harmonics and if the pins are really the issue then that there is the source of wear and tear.

More harmonica than? Gen1? Part yes but not really hence two primary chains. Further have you seen the new balancers that just came out. For oem I’ll be hot damn. Ford done put a great balancer out as updated part.

Harmonics are too much due to the cams being so lazy and if standing next to me in shop on timing motor if I turned by hand slow you hear pop pop pop pop that’s cams unloading and things hitting fan. Pins are an issue far from the only but I am huge in failure and tear down. Analysis so I have maybe 80 year down and write ups on raptor specific

Also cams are heavy on snout end very in fact. Valve train is stupid heavier than gen1 we cut 60% or more right out without a worry. Stock cams don’t do too much wobble wobble with them ground to a real or better spec. Stockers don’t open on power stroke and when you get there your shot in foot and way to much overlap killed your top end.

ARP 12 point cap bolts with billet caps help and billet cams [emoji41] quiet as a mouse in heat

Cams are hollow to allow a rod to be inserted that’s hot and allow cam lobes to be installed. Not to save weight, it is manufacturing design. Heads have the most heavy valves and retainers it’s nutso

Awesome sir thank you.
I see they have 5w30
Would that be recommended or the 5w40

Is this the harmonic balancer you speak of?

Yes I had a bulk order come in and they changed the material and appears manufacturer as well. This is horrible pic but I’ll do side by side when I’m at shop

This one right. Just making absolutely sure before I order a case and dump my fresh amsoil I’ve got in her.

Curious as well.....but the that specific oil appears to be specific to Diesel engines and states that on the bottle.

They have a separate oil for light trucks (based on quick review of the website).
#8521 and #8531 (5w-20 and 5w30 respectively).

I hear yah. But rmb Ryan said 5w40. I understand it’s diesel specific. I used to run rotella t6 in my evo 10 and it was diesel specific too. But it had higher additives that were better for turbo vehicles.
Anyway I still thank you blazinpond for your input .
Now if rmb Ryan can confirm for me I’ll leave him alone
