WHAT IS PISTON TO VALVE CLEARANCE? THE ULTIMATE GUIDE TO SEEING AND UNDERSTANDING PISTON TO VALVE! 

Well, this P to V is cheaper than eighteen years of child support.

😂

I love when my P is destroying the V😂

Suck squeeze bang blow!

Good info, Richard. I've always heard that a tighter LSA will reduce P to V clearance. Say, a 110° LSA will have less clearance than a 114° LSA. After watching your video, I can see that would be correct.

I want to show where the valve hits on the piston and why LS dish pistons might not improve p-v

@@richardholdener1727 would really be helpful to show how to test VVT and or lobe separation angles/LSA with a bigger/aftermarket parts and how limiting the phaser, change's-different's and for others the importance of it plus showing valve floating and deflection's-all-parts and why's it's okay and in some cases it's extremely a bad idea/thing to have. having a pushrod that's collapsible/expandable aka something like a hydraulic cylinder ( and or figuring a way of pressurising the lifter's in the cut-away, basically how my engine now works with a jerk-pumps and pipes/liquid-rods and slave-cylinder's and software/ECU instead of fixed steel-rod's+rocker's ) and a hand/porta-power ram-pump can showcase differences 😉 👍 , also a different but related idea is having a extra sloppy/stretchy piston or piston-pin can show were/high-mileage's/lacklustre-maintenance and also higher loading/RPM and how it can change P/V clearances and timing ect something i kinda/think 🤔i know how just not 100% testing processes/setup/efi-ect-tunes yet on my modified 1960's-540~ci hemi 4.3X4.5" stroke as i add a 60*lsx twin phasers ( yes i need the limiting blocks/software-lock's but not fully sure on maximum setting's yet 💯 ) to change VVT&LSA timing's ect plus VVL/multi-air system and variable valve-spring-rate like a f1/race-engine car ect

I did that

Glad it was helpful!

dome pistons usually have valve reliefs, so p-v is increased

the cam that makes more na power will make more boosted power-stop with all this overlap talk

the head was a piece of junk to start with

.035

Same I milled my heads to 58cc and have a 232/242 .600 / .600 113+3 cam. Clay method showed plenty of clearance but would be cool to see in action.

I can remove the gasket

706

BIGGER OVERLAP?

a lot

lots of cam tests up-but can show p-v difference

test ptv at the extremes of the VVT (full advance and full retard), many ECU systems don't use all that is available

if you already know existing cam (and specs and how it was installed) -then you can calculate

clay with gasket works

might be measured on a spintron

ford is coming

In machining, clearance is clearance. As long as your parts dont hit each other while everything cold or when everything's warm, thats it. A gap is a gap.
