Re: Broken timing belt on my 90 4runner
The reading at #2 shows that, at the very least, the head gasket is
blown. You MUST address this issue BEFORE you address any other
problems! The only way to check if the head or block is warped is to
take the head off and manually check it as described above.
REMEMBER...when taking the head off, loosen the head bolts ONLY 1/4
TURN AT A TIME, in the reverse order as the manual shows to tighten
thehead bolts. You will be starting at the outside edges and working
toward the center. IF YOU DEVIATE FROM THIS PROCEDURE, YOU WILL WARP
THE HEAD, EVEN IF IT'S NOT ALREADY!!!
Your manual will have the procedure for removing the head, it is
pretty involved, including removing both the intake and exhaust
manifolds. If you've never done this before, follow your manual's
instructions to the letter!!! Keep your fingers crossed that the only
problem is the gasket.
