question about an engine in need

hubba · 07-28-2005, 03:48 AM

hi everybody! im a long time reader of this forum, but this is the first chance ive had to sign up and use it. heres the hap's: ive got coolant coming from #6 into the exhaust manifold. sucks, i know. if i ask any questions that come across as stupid, its cause im just getting over the "i cant work on this car, its an import" phobia. anyhoo, my questions go like this, before i go tearing the head off, can anyone give me an idea of what i might be looking for? a friend said it probably wasnt a bhg (but what the hell does HE know), should i be focusing on the head, or the block, ill admit im not fully versed on the inner workings, so, again, im not sure what could be causing this leak. oh yeah, this is an 86.5 7mge non turbo. any pushes in the right direction would be appreciated, thanks.

well i'd say if you have narrowed it down to #6 cyl pushin water into the exhaust manifold you may find that cylinder full of water i.e BHG

warning... warning..
do not start your car if this is the case... you can cause hydrolocking and bend rods if the cylinder is full of water

if you absolutely must start the car, remove all spark plugs and disconnect the coil... crank the car and blow all water out of the cylinders... put plugs back in reconnect everything then move to a safe place (if your car is stuck on the side of the road near your home)
if the car is far away from the destination of your mechanic or your home get it towed

you will find that the head gasket has blown... and rather largely around #6

the only thing you can do is tear it down and see what you find... did the car overheat previously? did it do it suddenly?

if the hg is not blown.. you may have a crack in the head or block (altho not common)

if you can see clearly it is the head gasket
get the head machined and checked for warpage etc
new head bolts and head gasket from toyota

clean the block surface, if you are not sure how.. get a recondition shop or mechanic to do it for you
once you are ready to put back together, torque the head down to 72ft lbs on your new bolts
the torque setting is very important... make sure it is done to 72ft lbs or you will find another bhg on your hands at some stage
