I have a 1984 Blazer4x4 with a GM Goodwrench 350 and a THM700R4 that
was rebuilt about a year ago and it seems to have a sticky spot that
causes the engine to bind.
Over the last three years, the blazer has been eating starters every
four months and ring gears about every 12 months and I finally think
I found out why. The engine seems to stick.
A little while ago, the starter went out again. The engine turned
over for about 20 seconds, then we stoped the cranking and then tried
to start the craning again. All we heard was clicking. We hooked up
the trusty battery booster and we still got a clicking sound.
Thinking that we had a bad spot on the ring gear, we got under the
truck, took off the ring gear housing and tried to move the flywheel a
little bit using a wrench. Up until now, this technique would have
moved the flywheel. However, It would not budge. Finally we got out
a breaker bar and and we got it to move and after that the engine
could be turned with our usual technique/effort.
This tells me that there is a sticky spot that causes the engine to
bind. I have noticed that sometimes when we are cranking the engine
that there is a spot where the engine binds. I has attributed this to
a ring gear problem but it seems that it is related to the engine
problem I described above.
Has anyone run into this problem?
