Thread: Trouble setting timing.

yea their all rock solid. i checked about a week ago.
just checked them again and their solid.

idk what to do anymore, might just order a new motor so i dont need to deal with it anymore

i reckon the chain is fine.

noise sounds valve/lifter/rocker'ish to me.

What do you think is the best solution for me at the moment?

Is the tapping noise in this video coming from the top of the motor or the bottom? If it's the top, it sounds like a HLA isn't doing it's job. It's a bit of a PITA, but you would need to pulls the cams and bleed the HLA's. Refer to the FSM for this procedure. It could be one is stuck in the "down" position and the cam lobe is slapping the rocker instead of continuously riding on it. Check all of them.

With the cams still installed, see if you can lift the rocker off of the HLA. You could also take a feelers gauge and check to see how much gap there is between the base circle of the cam lobe and the rocker. There shouldn't be any.

i have feeler gauges. so there should be NO space whatsoever between the rocker and the cam lobe?

if its just the HLA i dont mind taking them off and bleeding them, sounds like a lot less work than anything else ive thought up.

Il check to see if i can pull up on any of the rockers. im hoping that it is something repairable. Do the HLAs just pull right up when you remove the cams and rockers?

I'm not sure what the exact spec is. My understanding is there should be little to no gap there, however.



Yes, you can get them out by wrapping the end with a soft rag and pulling them with pliers. It's a really precise fit and there will be some suction, so be patient. Be careful to put back things where you found them. It helps to work on one rocker at a time. Be careful you don't lose a rocker guide or the shim when removing the rocker. The are just sitting on there with nothing holding them down when the cam is out. It's really important the shim goes back where you found it. The check ball inside the HLA can be tricky to disengage. I didn't have the proper tool, so I used a large paperclip bent into an L shape to get at it. Refer to the FSM if you need more info on bleeding HLA's. Index of /FSM

Maybe take EVERYTHING out of the head, not including the springs, bleed the HLA and reinstall everything correctly. If you still get the noise, maybe get a new engine.

Time is $$

I will check if there is any lift on the rockers. Hopefully this is the issue.


it definately sounds like its coming from one of the rockers thought, doesnt sound to much from the chain side, just sucks that this happened pretty much at the same time i had issues with the timing..i would assume that this is unusual.

bled my hydraulic latch adjuster's (HLA) today, didnt have enough time to finish it up and get it started but i will tommorow after work.

if this doesnt solve my issues, any suggestions? replace the head or whole motor?
