well you're more likely to have health problems from the exhaust with any unburnt methanol which is quite deadly.
Sorry but you won't get much methanol in the exhaust of an engine as it is almost completly burned off. Even if the burn is incomplete the unburned componets are carbon monoxide and other compounds. Also even if it is run so rich that there is unburned methanol you will not get enough to be a problem, and your body will decompose the toxin and dispose of it in your urine. However the effects of TCP accumulate and cause irreversable damage to your nevous system. True methanol can cause irreversable damage but you won't get near enough from exhaust fumes. However TCP from jet fuel has shown to be very harmfull in the air bleed air conditioning systems of jet aircraft when it leaks into the system.
TCP is used as an additive in turbine engine oil and can potentially get into the airliner cabins via a
bleed air "fume event".
Aerotoxic syndrome is the name given to the alleged health ill-effects caused by exposure to engine chemicals; UK industry-funded studies are yet to make a link between TCP and any long-term health issues.<sup id="cite_ref-5" class="reference">

BTW See the movie "Water for Elephants". In that movie Camel drinks "Gingerjake" and becomes lame with "Jakes Leg". Gingerjake was laced with TCP to deter drinking of the product.
