I snapped the head off of one of my intake manifold bolts. My manifold has an “X” designation on it indicating 4 lengths of bolts are used, the odd one being at the right front engine lift hook. The one that snapped was in the 1-4 sequence locations at the middle of the manifold.
Now my 4100 is an 83 model and the bolt set used for the manifold use two washers per bolt.
After spending some time searching my local u-pull yard, tearing into 4100’s; an 84 and an 85 to be exact; I discovered a discontinuation of the use of washers on the manifold bolts on the later models.
I compared the newer bolt with my originals and found my original was slightly longer to accommodate the thickness of the 2 washers and the bolt head differed slightly, other than that their identical.
So far I had been unable to find a match.
Can I use the newer bolt sans the washers as a replacement for the one broken older bolt with washers?
DOES IT MATTER?
