Hello. The timing chain guide bolts on this engine are an M6 x 1.00 30mm. You will need to remove the rest of the broken bolt from the engine prior to replacing these. The replacements are available over the internet and I would opt for the ARP brand as they are very good for this engine. If you need help installing a timing chain, a qualified professional from YourMechanic can come to your location to assist with this repair.
