Head bolts are not really optional. When a bolt is torque that high they stretch. If you reuse them and they don't break they won't hold there torque because the elasticity in the metal is gone.

 

Straight from the factory service manual: "If the head of the bolts are marked with any kind of paint or if it is unsure whether or not they have been used more than once, then discard the used bolts and acquire new ones." If you're positive that the bolts have never been removed before, then they are safe to reuse. If you don't know, or if they have been "marked," meaning they were retorqued once already, then just buy new ones.

 

Isn't it easier and safer to just replace them? They're bolts! We aren't talking about a 5000 dollar supercharger or something. I have always been taught to replace them. That's been my experience since the first engine I rebuilt when I was 12. Just my opinion though.

 

Honestly, this is one of those things that isn't worth half-assing. Replace them so you don't have to run the chance of doing it all over again.

Yeah, you COULD reuse them, but why pinch $5-20 bucks, and run the risk of having to "re-spend" on another repair?

If you can't be good, be good at it!

 

Mah man! The voice of reason lol

 

back to rods and mains? no lifter issues here just low oil pressure

 

Hey how u doing anyways i had the same problem so at first i thought it may have been a leak in my cylender head right had 200,000 miles on it understandeble so put a new one on it now i still running very low oil pressure and of cource when running little or low oil pressure ur engine can over heat do to to much friction build up so i went ahead and changed the oil sensor and the oil pump and there it was oil pump was original and my jeep is an 89 so i changed the sensor as well figured why not just replace them both sence im already dirty and oil pressure is normol again and no longer wanting to clime up on th heating up lol i hope this helps u if u have any questions let me no thanks for reading

After reading a similar post, I have decided that I am no longer going to read them. I'll just skip over them.

 

But its hard. It's like a train wreck. So terrible but you can't look away.
