Knocking Noise

Thanks for that info that it doesn't always work. I will have to keep that in mind.

Exactly i don't do it anymore after mine started and shot up to 4k on a cold start which could have been really bad luckily it was fine and then engine still runs

Same thing happened here

That's terrifying I was more worried about destroying a bearing over the chains, also question do you have the startup flare?

That's weird

Shoc remanufactured engine with pre oiler timing guide reliability

I’ve seen it in a few motors. 4.3 GMs are notorious for it. Used to happen to my moms Blazer all the time. If your motor can’t be rev’d out a few times a week it’s not fit for service. I ran my old Mounty to the rev limiter all the time. Had 220k hard miles, 20k oil changes and had zero...

Do I need to lubricate the washer with engine Oil? The install diagram is calling for that but that's nothing I've seen before.

When I did mine I installed it dry

I replaced both tensioner with a new one from Ford. The rear tensioner still makes knocking noise on startup and if I turn off the car and turn it back on it stops. Why it's still making the knocking noise?

Did you unplug the coil pack or crank sensor and crank the engine until the oil pressure gauge showed pressure?

Yes, I unplug the crank sensor and crank the engine until I had oil pressure. When I did that, I didn't have knocking noise on startup.

I drove the car several times after that and each time I had knocking noise on startup. I also changed the oil but it didn't help. I'm using Valvoline HM full synthetic 5w-30.

Believe it or not, sometimes a bad oil filter can cause this. Which brand are you using?

Mobil1

Mobil1

I use the m1 301a filter and mobil 1 5w-30 full synthetic high mileage in my opinion the m1 301a is the best filter other than the FL1-A from motorcraft

 

[2000co]

I'm using the M1 210a, that's what the website recommends for my car.

Any ideas what causing the noise and if there's anything I should do to resolve it?

That's correct for that year, is it a knock or rattle?

It's a knock or a thumb, not a rattle
