lifter ticking after driving... BP4W.
So is this normal seeing as they are solid lifters? I am using Mobil1 synthetic. Just swapped the motor into my 91. I haven't had the chance to hear another BP4W so I can't tell if this is a normal characteristic.
It isn't loud and maybe not even noticeable if I had the hood on (I haven't put the hood back on the car yet).
It isn't just one or two, which leads me to believe this might be normal.

Oh, you waiting for your solid lifters to pump up, bro?
I mean, i know there's thermal expansion and all that, but that number is soooooo small it shouldn't be causing a marked difference in noise before vs. after.
Source: On my third BP4W, and this is the third one that's dead quiet cold and hot. The injectors on all cars were/are louder than the valvetrain.
In fact, out of the 3 running and driving Miatas i've had... turns out they were all 4Ws. I know what BP lifter tick sounds like, i had a tired shitty BP in the Escort.
Either i'm doing something "wrong" that makes the motors dead quiet, or....? <3

I figured they were quiet upon startup because the oil being thicker. Just for future reference, is there anyone in specific I could send my head to have it rebuilt and shimmer without costing an arm and a leg?

1) OP says it ticks after driving. As in... doesn't before, but drive it, it's hot now, now ticking.
2) I'm telling you point blank that none of the BP4W cars we've had had lifter tick at any temperature. Not open for debate, Pooky.
You can make a video, but i'm still going to recommend that OP check his shims, ESPECIALLY since it's ticking when hot. And your video isn't going to make my cars tick.

And that's weird that it doesn't tick when cold but does when hot. That defies everything I've ever seen before, and common sense/logic too lol

We have a dozen BP4W's at the shop, and I don't even want to count how many BP's I've gone through, the bottom line is some of them tick only when cold, and some tick always. The difference is probably "a little bit out" vs "a lot out" on the lash.

The third option is "not out."
Its not gonna be cheap. Its gonna be at least 250.

It just means his **** is out.

Seriously, lots of how-tos out there.

(Existing shim thickness + existing clearance) - desired clearance = new shim thickness.
Do this for all of your shims, sharpie their measurements on them, see what you can re-use in other places, and buy the rest. I ended up needing to buy only 8 of 16 total shims needed to be in spec.
Hint, you need to check your lash before removing the shims and lay them out so you know which one came from which spot.

Perhaps its not the shims?
OP: do you by chance have a real oil pressure gauge? I'd be curious to see what you pressures are dead cold and super hot.
Props for both of these guys. My BP sounds a lot better on the T6 than it does on M1.
