1973 Opel GT
Improper ball bearing size would be a problem that should be noted for anyone using stock rocker arms. So it’s good that you mentioned for those who stay stock.
Actually I didn’t know that. So thanks for providing that info. I know a decent amount about the CIH but this is my first engine build. So, there will be things I’ll ask for input from people who have done them.A seasoned guy such as yourself probably already knows the order in how that’s done, this is the order I was advised on my build thread:
Two from the front the others from the rear.
#3 first then 2,1. flip head pop #4 in.
Old-school seat grinders center off an arbor that fits snugly in the valve guide. The grinding stones are ‘faced’ to true them up and to create the correct seat angles.Bob, or anyone else, can you realistically do a valve job with a drill press? Or should cutting the valve seats be done with a machine built for it? I want to do as much as I can myself but I don’t know if this task is one you should handle on your own.
Charles Goin started a YouTube channel to cover various details of the CIH and how to build them.Also glad that this kind of information is being cataloged for future generations of Opel lovers to review and use long after we are gone. Thanks.....
Wow! Gopro Hero 10 are awesome! I have a hero 7 black that I got from best buy about a year ago. It still works great. The chinese accesories on ebay are pretty good and really cheap I like using those. I was thinking about getting a hero 9 but those are still pricy. Good luck with your channel!Charles Goin started a YouTube channel to cover various details of the CIH and how to build them.
Last night I bought a GoPro Hero 10 and a handful of accessories to start a vlog for this restoration project. I also finally determined what I want to name my YouTube channel for this, Zeppi's Garage. Zeppi is my nickname that I grew up with and it's what I've decided to brand custom parts I create with. So, it seemed right to use it for the channel. I don't have any content on the channel yet but that will change. Any videos I upload for the project, I'll post them here too.
Improved stiffness, improved side impact protection, provides for correct (safe) angle for shoulder harness,and....becuase we can! The problem with this install was that once the seats went in, nobody noticed; its almost invisible.Why are you planning on installing a roll bar in a street car?
Here is a fairly cheap GoPro stabilizer I learned about back when the creator was developing it. The guy who created this used the same resin 3D printer I have and he shared some of his progress on a FB group for people who use that printer. So, now that I have a GoPro on the way I bought one of these GravGrips. It's a neat product.Gopro... accesories
I want to contour the roll bar to fit more along the B pillar and having horizontal support bars that arch back into the rear storage area, so you really won't see it that well from the outside. I'm thinking the horizontal support bar could be bolted in, so it can be removed. I want to create a roll bar that blends well into the interior, so it doesn't get in the way. We'll see how well I can pull that off when the time comes.Improved stiffness, improved side impact protection, provides for correct (safe) angle for shoulder harness,and....becuase we can!

That is pretty cheap. I might have to get one.Here is a fairly cheap GoPro stabilizer I learned about back when the creator was developing it.

GravGrip is a gravity operated hydraulic gimbal for your Cell Phone and Action Camera. The perfect mix between a gimbal and a JIB device. GravGrip creates smooth camera transitions while your camera's EIS (e.g. GoPro Hypersmooth) removes small shakes and jitters. GravGrip features a...gravgrip.com
Opel cam bearings are numbed front to rear because they are smaller going to the rear. When you open the cam bearing box they are in order but if someone has opened the box or they fall out you can look at the number on the bearing and look on the box lid and you will match the number on the bearing to the correct position.Some news today on my restoration. The machine shop (Performance Plus here in Abq) called yesterday that my engine work was done. So today I went over after work to pick everything up. I got home and was emptying all my stuff into the garage when I realized I was missing the timing cover. And then it struck me, the shop probably forgot that the timing cover has to be decked with the block. So, I left the engine block in the vehicle and went back. Sure enough, they forgot. I didn't get mad or try to blame them, it's an easy mistake and unless the shop is used to working on Opel CIH engines they are likely to forget this. No many engines need the timing cover to be decked. They immediately said they would take care of it. The guy who did the work on my block said he'd get it done for me to pick it up tomorrow (Thursday). The shop did a good job so far though. The engine was beautifully cleaned after they put the block and head in a vat and oven. The shop bored my engine with the honing plate and fit the pistons for proper clearance, decked the block and decked the head. They also checked the mains and crank, ground and polished the crank journals for 0.010" over. Total cost was $674.22 for the work that was done. Wait time was roughly 5 weeks. I think it was a fair price for good work and good customer service. I visually checked the piston fit myself and they fit pretty snug. I don't have any measurements yet but I will when putting it together. I'll post pics once I get the block and timing cover back.
Question for the engine builders... how do you get stuck cam bearings out? Should I put the cylinder head in a freezer?
All the machining on the block is done, so here are some photos. The ruler is by no means an exact straight edge but it does the job as far as a head gasket is concerned at the timing cover. The block was decked I believe 0.008”. Just enough for a fresh surface to be smooth enough for a MLS head gasket.Picture of how much the timing cover sticks up or not.....
Nice! Did you try ordering the cam directly from Isky? Supposedly they can still provide them. Did you order new lifters with your cam or did you already have a new set on hand? I have an OR-77 I need to sell as well. I'll post it soon for $250, I believe it's gently used but I can't tell from just looking at it. It looks new.Just want to say thanks for all the piper cam links. I got me an adjustable sprocket and their fast road cam on order. I got the sprocket quickly. Cam will probably make it soon. OGTS was out of OR-66 but the piper cam looks like decent specs too just a hair less lift.
