If you had 1 noisy lifter...

Good god, that almost sounds like rod knock.

Cmon earl, you mean the volume level right? Its too fast and mostly goes away when driving. Ive changed the oil filter twice so far, ill get them cut open. Ughh..

Did you ever figure out what lifters you have?

I would replace them and be done with it.

No. Seller thinks comps but not sure which ones. Full throttle thinks morels.

I will change them. Please give me your recommendation for which set.

Made some calls on this and was told to add another 3/4, total of 1.5 turns. Gonna try this first.

1.5 turns of preload, wow... no

Im going lean much earlier than i was before my 3/4 turn. Vacuum leak or did this bring my total lift up to where it should have been all along? Ill recheck my vacuum lines either way.

Just thought, its also 50 degrees cooler here now.... On average, what percentage of fuel are you adding?

50 degrees is a lot cooler for a turbo engine, add fuel until she's happy again.

Rule of thumb:
+2.5% for every 10F drop from baseline temp tune

Almost spot on, thanks

How about the lateral play in shis spacer?

You should be able to adjust that out I would think. Is the other spacer loose like that one?

The noise is driving me. None of the lifters were soft at all when I reset the preload.

Comp lifters are notoriously loud

No, that is the worst one. I shimmed the other side with with a comp .015 valve spring shim. A shim here would put it too tight at .02.

Fwiw, the lifter sounds much louder in my video. Now that is colder here, i dont hear it till it warms up.

Do you mean adding 2.5% to the entire A/F table or are you referring to the VE table? Im thinking you mean the VE table since the air will be colder and more dense and therefore requires more fuel to attain the target AF

That's in % of fuel.
