Mike, that is lucky indeed...roughly 30 miles if my conversion math is right. Nice little day trip...maybe you can get a factory tour to boot.

I just got back from Roseburg with a replacement block (a 300 mile drive) and dropped the block off at the machine shop. Crossing my fingers that this time things go a little better. Seller claims it's standard bore, but we'll see. It has a serial # of RJ280701.

I got a call from the machine shop today with an update on my engine. They took the block to another shop in Portland to have it pressure tested and to get a second opinion on the block's integrity. They are telling me I have a crack-free block. 😃 The second block measured at standard bore but it took a 0.040" cut to clean it up. They got me some 0.040" pistons to go with it. This is on their dime.

I picked up
the engine block from the machine shop today! Just to recap: the shop said they
would stand behind the promise they made me to “take care of me” and they did.
They hot-tanked and cleaned the replacement block, bored and honed 4 cylinders
and supplied 0.040” over pistons and rings, decked the block, installed a new
cam bearing, installed all new valve guides, ground the seats and threw in a
Felpro gasket set. There were a couple of bad exhaust valve seats in the
replacement block and they installed all four with hard seats because they said
“it was the right thing to do” even though it wasn’t part of the original
build. I believe the owner said it amounted to around $900 worth of work but
today I picked it up at no charge. This project
has taken a lot longer than I had planned and took a few twists and turns along
the way, but in the end I think I’m ending up with a better engine. I also killed
a mole in the back yard today! Not bad for a Tuesday. |

Good to have the block back home again. The cast iron got a coat of primer on the outside, everything else was painted already from the other build. This block has one head stud that has been oversized where the coarse threads screw into the block, but the stud above the deck is still 7/16". Haven't seen one of those before. |

Those repair studs are not uncommon in the aluminum cases of VW air-cooled engines. Another fix for bad threads in the block/case are Case Savers. They are basically a bushing threaded on both the out side & inside diameters. The inside threads are the same as the original studs take, the outside threads are two sizes bigger. One has to drill & tap the bad hole to accommodate them. Both solutions work well.

Those case savers sound like what I've always heard called heli-coils. I've used them bunches of times when have to deal with bad threads.

Heli-coils don't have to be drilled two sizes bigger to use them. The "case saver" sounds like a larger item.

I should have also mentioned Heli-coils in my first post. Sorry.
Mike is correct, I have used both Heli-coils & Case Savers. Heli-coils are made like a tightly wound spring, while Case Savers are more like a bushing. Heli-coils do indeed use a smaller hole than does the Case Savers. IME, all three of these work well. Heli-coils are the most readily available. Yet, one needs to buy a kit that will include a special tap & the drill needed for it along with five Heli-coils. If you need seven of them, you get to buy five more. Case Savers use standard taps & drills. Back when I used to buy them one could buy just one of them. Those stepped studs are usually made in a machine shop & are expensive because of the labor costs. |

I'd never heard of Case Savers before but if sounds to me like that if there's enough room around the stripped hole for a Case Saver, it would be the better option over the heli coils that I'm very familiar with.

Never seen the "Case Saver" brand, but I have successfully used a product called E-Z Lok (www.ezlok.com) , to restore stripped 7/16-14 holes for the head studs. They do require a bigger threaded hole than helicoils, but I like the robust nature of the E-Z Lok's carbon steel. You don't need to remove the engine and they use standard taps and tools.
I used different diameters and length of E-Z Lok's, depending on damage done and how much block material there was to work with. I fit them to be flush or slightly below the deck as I wasn't going to have the block planed: E-Z Lok 319-7 7/16-14 inner x 9/16-12 outer x 9/16" long and 329-7 which is 7/16-14 inner 5/8-11 outer x 21/32 long. Get a good quality bottoming tap for threading the block. Install the E-Z Lok first with permatex #2, then the stud with more #2. They come with a locking compound on them, but I opted to remove it and use #2. I got mine from Zoro Tool, but I just Googled them and they now have them on Amazon, and some sizes on Flea Bay. Zore Tool had good deals on both taps I needed, too. How'd they work..? Well, I replaced 3 bad holes and all I can say is there are no leaks or complaints so far. Jeff |
