Did a timing belt break?

A weedeater and blower followed me home.
Both have carb issues.
The Stihl weedeater is 15 yrs. old with just a yearly airfilter cleaning.
It is in great shape.

Stihl 430 blower has duct tape on the harness.
Dirty but it runs

No belt, just saw the ID of the motor.
What is killing lifters?

What is killing lifters?

GM is having us replace what it known as the valve lifter oil manifold any time we get an active fuel management lifter failure.
It sits in the valley and has solenoids which dierct oil to the lifters to "unlatch" them during cylinder shutdown.
It's thought that slight internal oil leaks are causing the latches to fail.

I personally think its asking 1 thing to do too much. Ive seen the lifters blown apart into 3 pieces, I've seen them stuck in their "on" positions, and I've seen them collapsed.
Sometimes it pretzels a pushrod, sometimes not.

These engines have them on 4 cylinders, #1, #4, #6 & #7.
The new gen engines in the 2020's have them on all cylinders and can effectively shut down up to 6 cylinders if everything is met...yes, it will run down the road as a V-2.

DOD delete ftw

I actually get better fuel mileage with mine turned off.

For what it's worth, I have never heard of one failing in a truck that simply had a tune to turn it off and left the active lifters still in there.
The constant latching and unlatching by oil pressure is what must be killing them.

Lol...when i saw these i knew exactly who you were talking about. His Sasquath encounters stories are priceless

Seriously. You should check out the high tech BS he was spittin' this morning.

Just about every post of his makes me think of this meme:

Like you said, “one component doing to many things”.

Run the engine on 2,3,5 and 8.

I also installed a catch can on mine. You’d be amazed how much slop that thing catches.

Being at the dealer and constantly working on the new stuff, there's times I view the 6.0 in my 2006 as old school.
Iron block, aluminum heads, no variable timing or active fuel management.
Those engines run damn near forever..

Are you seeing any patterns with the failed lifters? Higher Mileage or cold weather or anything like that?

 

[Mastermind]

That gives me the sads... treehouse deserves better.

Butch even allowed him into the Tribal Elders forum. When I saw that, I said my goodbyes.

Butch ain't got much time left at all BTW. Lung cancer.

Nope..
Todays victims had 125,000 miles on the truck, 60,000 miles on the Escalade.
I've replaced them under the 36,000 mile bumper to bumper warranty too.

I have noticed that any time I have an intake off, I've noticed that the lifter manifold bolts are backed out and loose. Usually can remove with my fingers. So, loose bolts, oil from block, into manifold and back to block to lifters, yeah, there's your oil leakage issue..

350, all cast iron, 4 bolt mains, 1 wire HEI, Q jets, or Holley done properly.
The lastest i go is 1999 5.7.

Yep I'm not convinced that the new stuff is better honestly.

 

[Bilge Rat]

The new tech makes more power with less fuel but it is not as durable in the long term.

So both my uncle and my dad are fûcking with you?

Love how you got “F” word in there!
