I was reading back through to see if the ring gaps were mentioned but I have not seen that yet. Any chance it actually butted the second ring, breaking it first and torching it second? I am not experienced in boost, so I am asking honestly if that can happen.
I don't really understand how it...
I use these discs too. Love them. Last a good while too. I thought I remember them having steel bristles inside those plastic bristles but I have not paid attention to it in a while.
A few years ago someone on this site was recommending carbide tipped gasket scrapers. I bought one to try and it is pretty awesome. The tip is not deteriorating like regular steel or plastic scrapers. That means it stays sharp and allows it to cut through really caked on gaskets and sealers...
You can use either one of those or the cobalt recomended. Use a sharp new bit with cutting oil and don't go too fast. The cast iron will drill much easier than you are expecting.
If you do break one of those three types of bits, which are really just coatings on the bits, you will have one more...
Good things come to those who wait. Don’t worry so much. DVW says that guy is good. I would much rather wait longer from a really good small shop instead of rushing it through a high volume shop with lower standards. I am hoping you’ll be impressed with his work. We have a long winter ahead still.
These days, there is good roller lifters available with inboard link bars and no giant rivet heads. I am thinking those should greatly reduce the grinding needed to prevent this, but I have no experience with them yet.
Are you still building yours or has it been running a while? I remember you posting before about this and it is one of the very few I have seen with the Victor heads.
It's winter here Michigan. Are you planning to actually drive it with that carb on or just idle tuning in the garage? I enjoy tinkering, but may not be worth the effort unless you are going to take it out for a drive.
How about posting the previous part number without pushrod oiling and the new part number with pushrod oiling. Seams like that could be helpful in this type of thread.
PRH, I am pretty sure you are correct. They even had an article on one with stuck valves and that it needed to be fixed with bronze liners, but then at the end of the article they say something like "oh, and it had an intake air temp sensor reading wrong so we replaced that too." Fuel injected...
