Been reading up, i don't think it's bottom end now, the noise is nowhere near consistent enough. Think i'll need to pull the cambox off, have a look in at the valve springs for any weird signs and maybe pop the cams out for a look too if it's still there when the gearbox is back on. Still gutted i even had to take it off for a look, tbh i really can't be arsed with it all now, i've counted how much i've spent and calculated roughly how many hours work put into it.... all for some complete **** to go and fail it on stuff like a diag plug rubbing an air filter and a fuel filter that doesn't even move being insecure etc etc, it never had a chance. Then to treat it like **** and hand it back broken?
Just lost all heart with it, didn't even want to look at it today but was briefly at it, inspected flywheel, checked all bolts were still torqued up, popped clutch back on, hit my elbow really hard off the brake caliper and just launched my tools into the toolbox and went home at that point. I'm at a point where i don't even know anymore when i come home what's dirt and what are bruises, fed up of being filthy, hurting all over and getting cooked in that ****ing way too small garage.
