I always thought it was about 1.3 max on the standard gasket, but with other factors involved, i.e, engine temps etc. I would of thought how well your car has been mapped determines how long it will last. Too lean and cylinder temps and pressure goes up, and thats not really a good thing, least of all your head gasket
I'm sure someone knows better. I heard the pistons can be a weak point too.
Anyone else wanna shed some light on this?
Oh yeah, did you find out anything about the Tech Tom? I'd like to know more about mine. My car seems to run crap from cold till the moment the tech toms oil temp hits 60 deg.
Would like to know more about it
Hope your good though Alex mate
