NOISY ticking

[hooken m]

so i bought my car like 3 months ago. and i noticed it had valve/lifter tick. so about two weeks ago i adjusted the valves. started it up and still have the ticking. its honestly unbearable. so i double checked it myself and even tripled checked it with a friend. while i was triple checking with my friend. i noticed a few of the rocker arms were able to move from the eccentric side to the camshaft. would this be the cause of my lifter/valve tick? my head looks very clean. would i need new rocker arm clips or w/e?

thanks :)

make sure the cam lobes are facing down toward the cylinder when you measure them.

Yea don't worry did that. Lol like I said I triple checked and adjusted it twice to make it perfect

do you have the rocker arm clips on? Did you check the engine hot or cold? Also make sure the cam spray bar is clean and lubricating them properly. M20's do have a noticeable tick but it shouldn't be as loud as you make it seem. What weight oil are you using?

[hooken m]

5w30 till it gets warmer out. all the clips are on. i did it with the engine warm. .30 on the feeler gauge. if all the above are correct. i would need new clips?

this is your problem. Do it cold.

+1, always do valve work on a cold engine

Yep, and .30 is too much even on a hot engine. Where did you get that number from?
Go .10 on a stone cold engine
And the thinest oil you should run is 5w40, even in cold weather

Great thread. My 84 325e is clatterring like an Isuzu rodeo, and I was going to use the Bentley manual as my guide. Really glad to know the clearances listed there are wrong.

Are they the same for the e head as well?

The Bentley numbers are correct, .3mm hot and .25mm cold. If the head is in very good condition (very low mileage or recently rebuilt) you can go tighter on the valves (.15mm intake and .20 exhaust cold). But if the valves tick when adjusted to .3mm cold the cause is probably worn guides and adjusting them tighter is neither a good idea nor is it likely to make the valves quiet.

ah-ha! thats the issue

.25mm = .010 in

.30mm = .012 in

ah-ha! thats the issue

.25mm = .010 in

.30mm = .012 in

Beat me to it... the mm/in confusion happens all the time

the eta engine will always chatter. even when done right. but yes, same numbers as the I.
