My local mechanic has a 45 series landcruiser ute with a VN-VP era buick V6 in it, supercharger possibly off a toyota its not overly thirsty, and it goes pretty hard
as for Ecotec 6's being thirsty, my VU ute with a decent 'roo bar hanging off the front still manages 8.75l/100km with the aircon on at 110+......
Why not get a tdv6 out of a wrecked territory, D3/4, pug etc??? There are conversion kits from simetek and bells in the u.k;) Or to be really different a td5(3.2L) a ford ranger:o it's built in the u.k in the same plant as the 2.2 in the defender/free/evoque but is in no way derived from the td5 storm that LR designed,,,there goes a flying pig!:D
thats the last time i say anything nice about an ECO 6...... bloody thing just announced tot he world that its munched a head gasket
Sprint, I have never come across an Ecotec that has done a headgasket. What are the symptoms? I have been told that at anything over 150 000km it isn't unusual for the intake manifold gaskets to leak, letting water into the intake ports. Much easier to replace the intake manifold gaskets than the head gaskets!
I concurr, i have done several intake manifold coolant leaks on these, similar symptoms to a head leak.Quote:

so far got the top end stripped down and the intake about to come off..... discovered a couple of the intake manifold bolts were finger tight.....
well...... no obvious damage to the head gaskets (i know, you all told me so), all the combustion chambers look similar, and honestly, i'm at a loss to what was pressurising the system
bores all look mint, can still see the cross-hatching, i've run a straight edge across both the block and heads..... all looks good.....
I'm worried :-(
These run a 135Kpa cooling system, it doesn't take much to get them to boil their heads off and spray coolant everywhere if they develop a sudden leak to atmosphere, thats why the inlet gaskets leaking can cause such a problem. Despite what i think of these engines they are pretty much unkillable, I'd stick it back together, new thermostat and rad (Repco special last week was a new radiator for $200:o) and keep on keeping on:D

whats got me is it doesnt strike me as a boiling type problem..... with the cap off, when i filled it up, it went from full and being quite happy to suddenly gushing coolant and gas or steam 6-8" above the filler neck.....
wreckers engine is gonna cost me $1200......
kinda tempted to bolt it back together and see what happens, but i think its going to be a waste of time and money
Sprint, they will do that if you don't bleed them properly. They have a bleed point at the thermostat and you need to have a radiator neck extension above that height.
