rear main and front crank seals
hi all, while pulling my t56 transmissionearlier this month to replace clutch/flywheel ***'y i noticed that the rear main seal was leaking a bit. do i need to purchase the seal installer j35621 to do this job or can the seal be replaced without the tool?(tool gonna cost$170 by the time i get it)also my crank seal on the front of themotor shows signs of leaking. seems to me i can pry that seal out and drive a new one in with a socket. while im there im thinking to replace the opti seal and water pump drive seal. i figured i might as well do the oil pan gasket until i realized i gotta pull my exhaust off and lift the motor. the exhaust manifold to pipe studs look a litttle worse for wear and even with heat i know im gonna break them. i really dont want to have to pull my exhaust manifolds if i dont have too. so the short of it is can i replace the rear main and the 3 seals on the timing chain cover without specialty tools and without dropping the oil pan?
i know some people are gonna say get rid of the manifolds but....$1200 trans repair
$350 new opti
$125 water pump
$500 new eaton 10 bolt
$2800 Christmas present for me
ps. transmission was popping out of 3 gear intermittently when decelerating.
and can anyone recommend a good set of long pipe headers that will bolt right in just in case i change my mind!!
