Default Machining Head After Blown Gasket??

So, my head gasket blew. I didnt over heat anything at all but I was running series 3000 tunes on my ADR. I was told that its too much drive pressure on the stock turbo (making 40 psi of boost). I was also told that because i didnt cook the head that i dont need to machine it?!? Anyone know if thats true? I bought the socket head bolts from Diesel PAP, i heard they are better then stock ones. I also have an OEM CUMMINS head gasket.

Thanks guys!

Machining is only necessary if there is any warpage, and as you said it didn't over heat you should be fine. Once the head is off and clean, you can check the head with a straight edge and feeler gauges.

Was this after you took it in? if the measured it and you are within spec? they just wanted to save you some cash. Now if you want to do something else then thats diffrent.

I havent taken it anywhere... I just dont want to take it somewhere and have them charge me to machine it when it didnt need it JUST because they wanted to make money! I have trust issues LOL!

HaHa, not unless your paying the bill! HAHA!

I was told you cant ring the head without machining the block too.

This local place wants 250 just to clean, check and deck the head. I can barley afford that UNLESS my Intercooler Kit sells.. Then ill do the WORKS!

Incorrect, buy machining both sides is SUPPOSED to make the best seal. I have done some research lately about fir ringing, and you can do the head, or both.

If your pushing more then 80psi you need to machine the head and block.If I have won the lotto I will foot the bill.
