Hi JW, new to your channel and love VW's. Adjusting the rockers reminds me when I had a spark plug burn through and the head was wasted on my 65 bug. I also had a 68 bus with a blown crank. I tried the heads on the bug and tried to start it but found the rocker assembly was too low. I put washers under it so I could adjust the valves and worked. Ran great and sold it a couple years later to my brother👍
Hey there Tim!! Thanks for subscribing to the channel brother! We all have some great stories about our VWs and I love hearing them, thanks for sharing! These little beauties as my pop always says are pretty forgiving to us shade tree mechanics, one of the reasons I love them so much!
Hey man thanks for the comment... my case is shuffel pinned on the center main bearing... you don't install an o-ring when shuffle finned. That's so funny because I totally just caught the same thing on a subscribers build... lol Thanx for being here!!
Is that a stock engine We are having troubles with my 2180 We don't understand the value geometry And we are not new to VW been working on them since the 80s
What about the pistons, lifters and deck height, these can also change the required length of the push rods. If it's minor then you may just need to shim your rockers. The only real way to confirm is to measure your cam at full lift then divide that in half. At this point is where you check the balance on your rockers. The rocker should be level with the head... or evenly distributed between the valve and the pushrod. No matter the application or size of engine the point is to balance the load and pressure between the valve and lifter. At full spring compression it is also important to ensure there is no spring binding.

Yup sounds like your going to need some new pushrods... they sell ones you can cut to length. You'll start with your rocker adjusters only about 1 turn off bottom. Here is a great video from EZGZ on how to measure and cut the pushrods. ua-cam.com/video/yfbSBcXzQXE/v-deo.html
I hate the idea of being "that guy," but isn't it important to ensure the shaft of the dial indicator is parallel to the shaft of the valve? If my angle isn't misrepresenting, it seems the dial indicator is straight up and down, while the valve is slightly tilted toward the bottom of the motor. In this case, the reading you receive would be just slightly less than actual travel of the valve. Maybe I missed something, but worth consideration. That said, this is a very well put together video with great information.
I didn't find that it mattered with the location of the dial location. Most important thing with location was that the dial maintained contact with the valve. Once zero is set the range of motion was the same.
Good explanation, but you failed to show and tell where the shims are at. Some people may think it was the valve shims between the valve spring and heads, and others think it is the shims between the rocker shaft and head. Moe
@@JWClassicVW Like i said, some will misunderstand what you mean as you say it. I know. I had taught automechanics to idiots for 3 years after working as a VW mechanic. Some just remember one thing and forget other things especially if they sound the same.
So glad I watched this a few times to get it. Had mine a little jaked. But now my ratio rockers and sitting perfect.
Thanks for the great video.
Glad it helped!
Doing a 420 lift cam on a stock bore 1600 motor right now: This is real helpful info! Thanks JW.
Glad to help
Good Stuff Jason!😃
Thanks for sharing the process good detail and vdieo work.
Thanks Dan... lots of editing still figuring all the tricks out. I'm going to order some solid rockers and go through the process in more detail then.

Thanks JW, I gave you and some other VW folks a plug on a Seattle VW show video I put together. I have allot more pictures so may do part 2 soon.
@@TimsWorkshopTJY Awesome!! Thanks brother, really appreciate it!!
Do you remove the black paint that comes on the new tins before you paint or just paint over it?
If its after market, like EMPI tin yes I take it down to the metal as the paint is a courtesy coat of paint and not meant to last.
just wondering as to why you left the plugs in? good video btw!
Lol... funny story there. With no compression building up the darn valve springs kept turning the crank and cam right past the half way point. Lol
Did you forget the oring on the second stud you replaced before you put the rocker arm on?

@@JWClassicVW I'm tasking about the oring under the rocker arm.
@@dmck2533 lol oh... not sure man that engine is in pieces under my bench... :-)
@@JWClassicVW Fair enough... We all know how that goes. Just watched your newest geometry video last night.
@@dmck2533 Awesome!! Thanks man glad your here... Part of the club!! ;-)

Yes this video covers valve geometry on a stock type setup. The video below covers it with high ratio rockers.

Thank you for the comment... good point!! I'll be sure to explain it in more detail with my solid rocker shafts.
