What size/specs is the head to timing cover bolt? (the one hidden under the dizzy drive gear)

length grade thread etc if anyone knows off hand. Mine has disappeared during the move to the new house and it's kind of important

 

Try www.toyotapartszone.com

 

i checked on there. they have 6 listings for bolts specific to the head. unfortunately no picture to verify which one is the bolt i'm looking for.

 

M8x1.25 get a few different lengths .

measure the distance the threads are tapped into the timing cover .

Measure the depth of the hole through the head get a bolt the next shorter size of the sum of your measurements.
