Why does the same ARP header bolt loosen up??
lost another header bolt today coming home from SLP day at e-town... it's the same one.. last one on the passenger side... lock washer didnt help.. i've re-tighten it over and over.. it's not striped, cause when i make it tight, it's tight..the first to last bolt on the same header tube is almost on it's way out... anyone else experience this? all the other bolts are tight and never leak.. can i use lock-tite with alum. heads? i have GTP stage II heads and would hate to ruin them with the lock-tite..
thanks

it has to do with the reverse cooling. because of the way the coolant flows through the heads, that paticular bolt has the most thermal stress on it, so it loosens up easier than the rest...i have to tighten mine every 2 weeks
