I got this dipstick from Summit for my 347 and am having some trouble putting it in. The old style timing cover is brand new. I used some penetrating oil on the end and attempted to "persuade" it into the hole carefully with a rubber mallet, also tried a steel hammer with a block of wood. I get it in maybe 1/4 inch. Seems like it is too tight of a fit, so I used some sand paper to remove the chrome finish at the base and retried to no avail. I don't want to damage the cover or the dipstick, so I thought I would seek advice from the experts here before I have regrets. How did you guys do it? Thought about using heat, but didn't want to burn up the fresh paint etc. Thanks in advance for the replies.
