3rd gen cyl head question

[trev1968]

my yota head went but the only cracks I see are in the injection combustion area would this put water into the oil ? cant see if the gasket had failed as I dident run it too far after it boiled

many thanks

I ran mine for a while when I knew the head was cracked and when it died (hydrolocked) there was evidence of water in the oil, Mine was cracked across all chambers and between valves in all cylinders except one. Deposits on filler cap only started a day or two before it died but they were there. Not sure if the gasket was failed or not really, was more worried about the head. Mine never showed hot. Luckily the day it died was the day the new head and bit to sort were delivered.

Cheers

I had start of water in oil, lifted the head and found cracks between valves on 2 cyls.
