While replacing a cracked head and gaskets I snapped 2 bolts for the rocker arms.
Not realizing these would be one time use stretch bolts until I was putting the rocker arms back on I hadn't ordered any replacements; turns out the best I can do to get replacements is a week and a half away.
So i decided to re use the 4 remaining grade 8 stretch bolts and obtained 2 grade 5 bolts to replace the ones i snapped to get me through in the mean time.
Looking for some technical thoughts on the stresses at work here and whether or not people think this is a big bad no no idea or if anyone had experience with a similar situation where lower grade bolts were used in the same application with long term success.
Also as a side note, a interesting string of events that led to my cracked head.
Found a safety seal from a container of coolant during the initial diagnosis.
This seal appears to have made it to the bottom of the coolant resevoir plugging the hole at the bottom. The rad would push fluid out to the resevoir then the seal would plug the hole during drawback eventually emptying most of the coolant from the system(resevoir was full to the top with signs that it had overfilled when I noticed the overheating initially). causing the vehicle to overheat due to lack of fluid which caused 2 blown head gaskets and luckily only one cracked cylinder head.
Very tiring costly repair for a stupid safety seal. So I recommend checking the coolant resevoir for stupidity when buying older used vehicles bahahaha.
So thoughts on the grade 5 bolts/reusing old bolts for the rocker arms? Besides not recomended lmao.
