any ideas on how or why the gasket blew ?. do you have compression in the cooling system or water in the oil ?
didnt mix genuine coolant and green glycol be chance , seen the results of that
. the whole front timing case needs to be removed to access the timing chain ,tensions etc.
not done it physically myself (never seen a 1gr head off in the 9 years theyve been in oz). have seen 2 or 3 timing cases off in a prado for a crank position correlation issue when the timing chain was over stretched. and had a trd hilux where a small timing case bolt fell out and caught behind the harmonic balancer and chewed out the cover.

not a job for the faint hearted i would suggest- do you have a workshop manual ??
