I used number stamps just like post # 226 for years and never had any issues. You don’t do it to a high performance build - but anything a 6.5 is capable of, it won’t affect it.

Here is another random one. I know there are some excellent videos of race legends that show how to, & show porting oil passages & such. But maybe they are gone so they can sell the info? Anyways- i watched this guy’s one video - he doesn’t show anything crazy wrong. It should give the...

How it is done in modern factories isn’t often shared because of trade secrets- basically Toyota doesn’t wanna share their system with GM. But here is the jist of why it isn’t a problem in modern manufacturing

I really suggest looking into some of the higher quality engine builders that make videos and watch their details. Removing flashing, improving oil return flow, breaking the edge. This is two random “shorts” how simple it is to remove the flashing.

Down in the block near the lifters is another place flashing is found and needs removal. The large passage where the oil is returning from the heads to the pan- here I have a picture after I have done 99% of flashing removal and started doing a little “while I am here” improvement that helps...

Here is the thread I am starting about flashing. I titled it with different terms so others searching the subject would find it when using one of the various descriptions...

Back in 2004 I bought a new optimizer long blog from Towbin Hummer. I knew I SHOULD have pulled it apart- but Towbin at the time gave me a 3yr/36,000 mile warranty even though GEP doesn’t. So I left it together and kept no turbo as mine was originally. I got to somewhere around 70,000 miles...

In the 1st pic, look at the tiny sharp peak edge. Then look at my finger tip pic. Not the same piece but examples of the fine sharp edged pieces that easily break off. In fact, the one on my finger, I broke off with my finger & I haven’t had great finger strength in years. The average...

See the point of the punch I am using as a pointer? That is a thin edge of cast iron. This needs to be removed. Time per average head if you only remove flashing and do no other improvements is 5-10 minutes per head of actual die grinding work. Takes a little set up time. You have to VERY...

Here is before/ after example. I don’t think same head I used here but you can see the flashing before removing and the shiny & smooth area afterwards. This is in brand new P400 heads. So yes, still a problem in the p400.

This subject gets brought up and people who know to do it, do so like putting on a sock before their boot because it’s that easy and that important. Anyone that has input, pics, videos, etc that helps - please share. When casting engine parts where the molds come together and where portals...

Coolant in oil comes from headgasket; head studs not sealed or a leaking head bolt; cracked block; cracked head. Or simply mistake of pouting some in there which happens at oil change places more often than folks know because they start out kids with no experience. The most likely issue of the...

It is real nice! Either. 4wd or MatTracks…😁

Flashing is a bad problem with them. Did you disassemble the engine and remove the flashing? That is where my money is. 100% agree with Bison- right now you probably have an engine worth saving IF AND ONLY IF you tear it down NOW. Don’t start it again. A new optimizer isn’t cheap- but...

All the ip stuff - meh. It says db2 is #1 failure point on 6.2… WRONG! It doesn’t cover the real things that make a difference. Add lube to fuel, Clear return line, fuel pressure gauge. For peak mileage/ performance- time it every 7-10 oil changes and let it ride. Replacing T-stat...
