After posting a thread about a month ago regarding pressurising the coolant system, the fault turned out to be the headgasket.
It was replaced for a new Toyota OE item, with OE bolts and 600miles later, et voila; Missfire on start-up, pressuring and blowing coolant out of the bottle.
My thoughts are, as with the head and block both being checked when I changed the HG and found to be true, that either the stock HG isn't upto it, or I'm experiencing head-lift.
The fault is obviously down to the combination of compression hike & boost and the standard items aren't upto the job.
For those unaware of this engine, it's a 4E-FTE, with 0.6mm skimmed from the head and 0.4mm from the block, creating the equvialant of the standard motor, with a 0.2mm HG, running 1.2BAR on a CT9B.
What BHP does headllift usually begin to occur? or is it a boost pressure?
Which MLS gaskets are upto scratch?
And ARP bolts are the best choice?
Thanks in advance, Tommy
