Daily Drivers with Hi Compression

[WhiteAP1]

Oh i see. lol

On the retainers,from what i read it seems the intake side are the problem. The exhaust retainers don't crack, because the valves would hit the piston first. Also, the exhaust valves don't float at the same RPM as the intake because of their weight.

heres a bit more reading

Hmmm, interesting read,
That's an odd problem that we've not yet encountered.
Looks like valve clearance issue combined with a loose nut between the steering wheel & the seat.
I'd be quite interested to find out if Honda have had any genuine warranty claims on this one.

i run higher compression than 12.5 in my b20b + JUN stage 3 CAMS.. on shell v-power ... my verdict.. LOVE it...

i have done it and it's fine.. no detonation on my engine..
still drive my car out everyday to work... (dont tell the cops that)

also with valve hitting the pistons.. there are so many ways to get around it...
so it isnt a problem if you know what you are doing..
valve hitting a piston is an amatuer problem. so should not happen if you bring it to a proper engine building shop..

and also if your valve hits the piston ... trust me it will not be hairline cracks..at high revs you will know... for sure...

it goes boom, boo, bo, bzzz..
