Hey buddy, it’s me again! So I am currently attempting to do a valve job on my CCTA head. I have never attempted to do a valve job before but I want the challenge! So I have a couple questions: 1) if you remove a head form a vehicle that has gone out of timing and has bent all intake valves. What all would have to be inspected/replaced before even considering doing a valve job on the cylinder head? 2) if attempting to do a valve job, could you “over lap” a valve while using the drill method? 3) what would be a good method to check valve seat at home? Pour water in top of the valves and wait for the water to dribble out?

Hey bro! Make sure the valve guides are not cracked. Yes you can use a drill on low speed You can use water and cover the valve then use compressed air in the ports and make sure there are no bubbles then dry everything so there is no rust.

@ivanvega2821 when you pull out the valve look at the valve port and make sure the guides are not cracked, most of the time they are not.

@@Motorcarnut as always my friend. Thanks for the help and the awesome videos! As a request, you should make a video on the proper way to remove an engine from a Volkswagen with CCTA!

I just bought this same compound and it says in the package is old grits from 120 to whatever 200 or so it doesn't specify the grit , so I guess it's whatever😅

It's fine, no problem using it.

As you use it the larger grit breaks down or gets squeezed out leaving the finer grit in the grind zone.

Does oil suppose to be on top of the valve stem in that whole

But still i think the manual hand is better way, because at drill speed will copy the losse of steam valve and guide on the seat

I’ve done both with great results. But you do have more control manually I agree

Would this work for installing new valves?

That's what its for, yes.

@@Motorcarnut Yeah in your video you took used valves and lapped them. I read that new valves need to be cut in order to seat properly. That's why I asked. It's comforting to know you can use this method for new valves. I really don't want to take my cylinder heads and new valves to a machine shop because things get expensive pretty quickly. Thanks for the video.

No problem, when you’re building a new engine from scratch and using all different manufacturer of parts, then yes, but when you are using parts designed for your stock engine there is no need. Hope that helps.

Why not use Prussian Blue to see contact pattern on valve & valve seat when finished lapping?

@tylerwright754 No need to if you done it correctly.
