Hey all, noobie here. Just did a JDM 3vze swap on my 90 4runner. It seems to run nice except for some ticking coming from what sounds like the intake manifold area on the left side. Someone on another forum said this could be caused by a vacume leak. Does any one know how to check that Madoosa of vacume lines for a leak??? Thanks in advance, any info will help.

Cheers,
K.C.

 

The fuel injectors are known to be noisy on the 3.0, could be one of them.
Get 2 ft of vacuum tubing, stick one end in your ear and move the other end around the area to see if you can narrow it down.

 

x2 My injectors like to tick a little.
