well this is what i did. I sealed everything but the head. i also blue locktited everything the head will not come loose. the engine in my rs4 3 evo+ 3.0 is 2 months old and its only been through 1 gallon but when i just did the sealing and i put the glow plug back in to test compression i have some SERIOUSLY strong compression compared to before. its a big difference.

Thanks for all the help guys its much appreciated. ive also noticed that the same thing with the mini mgt 3.0 engine its got some crazy compression now. hopefully i wont run into any leaks. One other ? when i get my savage 4.6 monday wich will be brand new should i take the engine out and seal it?

none of my exhausts are held on by any springs they are all screwed on.
