Hi,
Yes the cam lobes are off. The tops are to be laying more down equally to each side of the cams body.
That way nothing is depressing onto the valves bucket shims.
I don’t know how to get 135 degrees when it’s a four cylinder engine so you must be off by one-half, a 45 turn and one ninety degree quarter portion. I guess it depends from where you or how reference one from the other direction. It definitely sounds as if it in between so something jumped.
Since the belt is trying to walk off the sprockets, I would rip the front down and make sure the crankshaft sprocket is installed correctly.
It is easy to get the belt guide plates and the sprocket itself catawampus.
It is so possible to happen that the sprocket can get cracked.
This is because it is made from a sintered metal process of manufacturing and not billet stock.
The part entails both an internal and external keys let alone the grooves for belt teeth.
They just happen to still sell them separately from various vendors.
No wonder since the main crankshaft bolt gets such a high torque put on it.
As far as the belt tensioners setup, it has to be laying flat up against the engine as well.
All of the concern over the bearing can be well justified in this discussion as it does make a lot of rotations every time the whole belt makes one revolution.
Believe me that belt is flat out moving around in several feet per second!
In my past I have had one make a whining noise or shrill. It’s Then, you know it bad so don’t mess around with it.
These are technically “cam” bearings so they are tougher and wider on the outside than normal bearings and can go a distance.
I have put more lubricant inside one and ran it for some time.
It is not easy putting a hole into the side shields.
Considered it as a challenge. It’s not worth the efforts, as it did do all right.
Only once and I never again tend too.
That is, unless I was in a real pinch money or the part.
When you’re young, some things are just FUN!
Dumb can get found out later. 😳
Definitely not a daily-high miler car that seldom gets listened too or just driven hard and parked wet!
