head gasket m20 325i

[dumpydave]

Hi. May seem like a silly question but i'm about to do a head gasket on my 1986 325i. Do i need to get new head bolts? Are they stretch bolts?

[thebigone]

allways best to put new ones in, prior to that clean out the threads

[dumpydave]

ok mate, cheers. Do you know if they are stretch bolts?

[Brianmoooore]

They are torx stretch bolts. If the originals are hex headed bolts, they should have been replaced years ago.

thats excellent thanks for your help chaps!

i pulled the head off couple months ago on my 1983 320i and i found that the original bolts were still on, and i used the same again, but you should always use new ones Torx and you d not need to retighten them after the car is hot
