Hey mate ! Just got
my es300 last night haha . It's a shame the es300 forum is
not active . Yeah the 3vzfe engine is known to headgasket problems . It's a very strong engine though that's why alot of mr2 guys are putting it in their engines . Head gasket normally goes around 100,000kms plus . If you're interested I got a link from the mr2 guys for cheapskates head gasket parts . Approx 100 bucks
