IN the photo which is had to make out....and I took lots and this is the best one...
There is a line, crack, mold mark, something that runs from the right side of the timing mark boss all the way us to the water pump...There are also 2 small whatevers going from this long mark/crack/whatever up to the center timing mark marked TD...
Have any of you ever seen this before?  What do you think it is? The pump shaft turn freely, and I can see nothing in the shaft hole...The left side of the whatever extends far past where the pump shaft  hole stops...Thanks for any opinions....Bob in Alabama

	I take it your pulling the cover from your 73 304, and noticed the issues with your cover. I have a 71 and a 74 cover in the garage, and remembering my 73 when I worked on it through the years. The area in question, I have not seen on any of my covers. Could be a cast shift when created before the pour. Don't see your picture...

	This cover is not off of any of my cars and I dont remember where I got it....It was about the dirtiest cover I have ever seen....I was preparing it ahead of time to possibly use on the 71 Hornet when the timing gears get changed soon....I have a lot of time in the thing dressing all of the sl*g and rough unfinished edges, and cant believe the area where this funny business is going on is the last place I chose to get into detailed cleaning, but that seems par for the course....Bob Edited by mrblatzman - Sep/23/2018 at 7:06am
	Thankyou....Bob

	From what i see..it looks like it might be heat checking in the die, from which it was cast from.( which wouldnt hurt a thing.) See alot of this in casting process. Parts look perfect when die is new, ..then thousands of parts later, they start to show age.

	I think my 74 cover has something like that going on at inside area near the front of the timing chain or on top in the valley between the water ports. Sort of a plastic wrap wrinkley look. Like what was said in the previous reply given by bigbadgreen.

	If in doubt, check it: https://www.amazon.com/Dye-Penetrant-Crack-Finder-Kit/dp/B00XLW4BRC/ref=pd_cp_469_3?_encoding=UTF8&pd_rd_i=B00XLW4BRC&pd_rd_r=0975016f-bed3-11e8-9069-65b0c08f01f2&pd_rd_w=vT4jo&pd_rd_wg=A8N2G&pf_rd_i=desktop-dp-sims&pf_rd_m=ATVPDKIKX0DER&pf_rd_p=3f5155f5-5438-4fc3-ab83-bf013cfc8883&pf_rd_r=TX5X27XDHKW1C84S5SVK&pf_rd_s=desktop-dp-sims&pf_rd_t=40701&psc=1&refRID=TX5X27XDHKW1C84S5SVK Cheap insurance. Check from inside of the cover, if it's cast flashing the outside will pick up the die regardless.
