Ebay is the best option, but you will have to keep searching or set up your account to receive emails when a brat item is listed. I am currently restoring an 85 brat as we speak.
What happens is the head gaskets shrink causing the headbolts to loose torgue, and the headbolts are of one time use, whenever you do a headgasket job you will need to replace all the headbolts with new ones. and when ever you remove a cylinder head on any engine you should always chase the bolt holes with the proper tap, then blow out the holes with compressed air, this will help to insure a more accurate torque setting on the new headbolts...
Hope this helps, from autozone site. Curt Application:
Cylinder head bolt torque sequence
Note :
Torque sequence:
---------
front | 3 1 6 |
of | |
vehicle | 5 2 4 |
---------
Step 1: Lightly oil cylinder bolt threads & washers
Step 2: Torque to 22 Ft/Lbs
Step 3: Torque to 51 Ft/Lbs
Step 4: Loosen all bolts 180 degrees
Step 5: Loosen all bolts 180 degrees
Step 6: Torque bolts 1 & 2 to 25 Ft/Lbs
Step 7: Torque bolts 3, 4, 5, 6 to 11 Ft/Lbs
Step 8: Turn all bolts an additional 80 to 90 degrees
Step 9: Turn all bolts an additional 80 to 90 degrees
*** CAUTION ***
engine uses Torque To Yield head bolts (TTY) that
permanently stretch during the initial installation.
New head bolts must be used when cylinder head is
replaced or re-installed to obtain proper Torque.
There should be 10 headbolts. This vehicle uses torque to yield headbolts and should be replaced with the new gasket. Bolts 1-8 get torqued to 40 ft lbs initially, bolts 9 and 10 get torqued to 30 ft lbs initially, Then all bolts get turned an additional 90 degrees. I would strongly suggest borrowing a torque angle gauge for doing this or you might be doing the same repair next week.
before you drop the tank if its not to late i think the fuel pump isnt in the tank on this model.it should be next to the tank on the passenger side.just above the back wheel.also i think they are 2 fuel filters also on this vehicle one is on the firewall and the otherone is located right beside the fuel pump where i just described i hope this helps thanks jeff
