Greetings LC community
New member here seeking some help/ advice. Have a 2002 UZJ100 4.7 on 226,000 Kms. Japanese spec VX LTD. Last few thousand Kms noticed rising oil level with fuel smell in oil. Has long range tank ( about 150-160 ltrs) , am getting pressure build up in tank noticed when I release fuel cap at refill. On two known occasions, liquid fuel was ejected from evap canister overflow draining out at front left of vehicle . I put new Denso injectors from USA on recently ( as worn injectors were indicated to be a possible problem of fuel leak). But still oil level rising. At start up in morning, sometimes see a puff of blue smoke exiting exhaust. Engine running smoothly, plenty power, no engine check lights on, no rough idle, . HELP AND ADVICE please!! Am not a seasoned repair dude as it's my first Toyota LC , owned it for 2 years andove it to bits ! Many thanks.
 
As you mentioned being not a seasoned handy man (mechanic).....why not take it to a local indy shop.

That being said, I would look into your charcoal canister and its hose lines.

Blue smoke is oil burning in the engine. Worn out seals and rings.

Injectors-Bad seal to the Injectors will leak fuel at the fuel rail.

Check the long range fuel lines for"pinching" of the hose line.

Good luck😎
