Title: Intake manifold bolt size
Post by: Chisholmcody on November 24, 2014, 01:32:39 pm

I was looking over my motor the other day (1978 l6 250) due to the fact that coolant was leaking and noticed that it was leaking from the intake manifold due to the bolt closest to the back of the engine bay was missing.

Now I'm trying to find a replacement bolt and was wondering what size is it? And also will I need a new gasket do to the bolt coming out?

Any help is much appreciated.

Can post pictures after school if needed

Can you pull one and take it to a bolt store to size it.  I don't know the size of that bolt though for a I6

Just didn't know if they were different lengths but I'm going to go try that after school.
