this is a joke right? the FSM simply says remove the bolts on the exhaust crossover pipe. they must be assuming the motor is out of the vehicle. is this even possible with the motor in? with as big a problem these head gaskets are im surprised noone has done a full writeup. probably because they just have the recall work done but this one's already had that once. any suggestions?

 

Give search a try.....open up the date range as there are post and writeups here. To wit, for one:

i honestly did search, i'm pretty forum-literate! i actually searched and browsed the forums. but i appreciate your help! i got it out of there!

 

just took the heads off a 94 ho'runner to replace.... you guessed it, another blown head gasket! here's some things i noticed, let me know what you think this may mean. all but one piston is black and has a light sludgyness, the cylinder closest to the passenger seat has about 2-3 times more sludgy buildup than the others. the cylinder closest to the driver is clean, light brown tint. the spark plug has quite a bit of cauliflower looking buildup on the j shaped part of the plug while all the others look rather normal. whats going on here?

 

The clean pistons is the cyl that had the failed headgasket. Coolant was steam cleaning that piston. As for the others sounds like a little rich, maybe because the coolant in the exhaust was messing with 02 sensor and it thought the engine was running lean.

Assuming this is a 3.0? since your referencing passenger and drivers side?

 

yes 3.slow the thing is, it's not the cylinder that had the leak...

 

SO what is the latest and best head gasket to get for the 3.0?? i have a spare engine i bought from japan and id like to have the gaskets changed while its on the stand before i put it in the truck why put a stock toyota one in that will fail ??? ive heard of m l s ( multiple layer steel)
anyone ??
thanks
