Do you know what size the checker springs are? Wanting to get an idea for hardware store options

[mightymopar]

What do you set valve lash at when you have a solid roller cam? cold lash setting? Thank you

[gerry.mcginty]

what the ckearance of the cylinder head gasket as you never installed it, before checking clearance

[slicksloth_]

Do you check with the actual pushrod length that you use just on zero lash snug rocker

[johndomine]

What about at 7, 000 RPMs when your hoping the vavles spring keep control?

I’m currently building a new 5.7 for my Camaro and I currently do not have a set of used head gaskets that are already crunched down. I assume that I need to measure proper pushrod length before checking piston to valve clearance should I install new head gaskets and heads torque heads down to proper torque get my proper pushrod length remove the heads and gasket check piston to valve clearance without gasket then just add my gasket compressed height to ptv clearance to make sure I’m golden then just reuse new compressed head gasket. Or just do the whole process without the new head gasket and just add the compressed gasket height to all my measurements ?

is there any way i can contact you ? i need help with some ptv clearance issues

[turbotysen]

what clay did you use? where do you get it?

[phillee]

Do you check a cylinder on each side or do you have to check all of them?

[timweb]

I have my lm7 opens up to check for repairs, what should I spray on the pistons/ bore while I have heads off to resist rust or corrosion? You recommend wd40 every week or so? Is it safe to leave an old engine opened up? There is a ton of junk I’m trying to clean . Thanks

[timothysirmon]

My only question is how can you know how much you can take off a cylinder head by milling it or know how much piston to valve clearance you’ll have when ordering like dome pistons or know how big of valve reliefs to order etc on an engine

[darrellhughes]

Hey Engine Guy I chat wit U on my build Ly6 6.0L stroke to 416ci! Will my pistons come dwn out d block wit dat build guy sayn dey will move if I bore 4.070, an dat bore nt safe. Wat U recommend?

[kenheady]

Is it best to check it with a solid lifter or does it matter

[dwestinghouse]

Great content. What do you do for the hydraulic lifters. Do you make sure they are pumped up or do you modify them to make them a solid lifter?

[carlrandazzo]

I noticed you kept looking at that guy with the air compressor blowing something off. I thought you were going to punch him out.

[RatRodBobBuilds]

There's lots of videos on Piston to Valve clearance and you should check out a lot of them to get a good idea. To start with, you need a solid lifter, or make a solid lifter to check it. My latest build has .055 on the intake valve. Steve Morris Engines has a good talk about this.

I never check piston to valve with hydraulic that not the way, use soild & way stiff springs then that to get real piston too valve, this guy sounds like someone else's did all the hard work 25 years ago for him, and all there clearance have been Done for them cookie cuter motor
