Hi All

Imported a Pajero Evolution from Japan and managed to blow the engine

We've pretty much got it all done and ready to rebuild but just wondered if anyone had any Torque Settings or tightening pattern for the cylinder head?

Found the workshop manual online for the 6G7 series engines and that lists 108nM but that seemed very generic considering this is a high performance engine. Also there is no torque pattern in the manual I found.

Also would be really helpful to get the tappit screw clearance heights if anyone knows those too. Can only find workshop manuals for "normal" 6G74 engines that have rockers

It's a MIVEC V6 3500 DOHC 24V

Any info greatly appriciated

You always start in the middle and work out to the ends.
80 ft lbs is about normal for a GTO 6G72. Some owners like to go to 90 ft lbs.Don't go more.

The torque setting is to do with the bolts, not the engine. The 6G bolts are all the same.

The tappet clearances, use the spec for the 1.6 mivec, service manuals on this site. From memory 0.1 or 0.15 mm, but you need to look it up. Set it too loose and it's really noisy at idle.

6G72 mivec Twin TDO5 20Gs up and running.
6G72 mivec bored and stroked to 3.4 litres...Frankenmitsi build
6G74 mivec bored and stroked to 3.9 litres....Frankenmitsi build.
6G75 under construction....4.2 litres bored and stroked.Another Frankenmitsi.
