During some engine bay work I seemed to have lost one of the four engine cover bolts. After using a surviving bolt against my metric die set there does not seem to be any that is a match. An M6 1.0 is the closest match but not exact. Does anyone have the bolt size or GM part number for this bolt? The next step is to try the Home Depot thread identification card. I just I would ask here first. thanks!
What I was looking for is the bolt size for the 4 small bolts that attaches the engine cover to the intake manifold. Thanks for the info on the DCT filter change.
I lost one while changing out my intake manifold, was able to take one of the survivors and matched it up at O'Reilly's. Pic has size you need. (Pic shows remaining stockers as I just swapped them all out because I couldn't find black ones local and was impatient)
Yep, thought why bother with a DIY Doc for my engine cover replacement, it's so easy. Then watched a Youtube video where a fellow with his friends screwed up the hose fitting in the front of the OEM cover. They removed while on the car- foolish! Then they installed it backward (50/50 chance.) Had to remove again. It was then so badly mangled it was very lose when finished!
My 5 Page Mostly just large Pics with long descriptive captions like my other ~60 How Tos. Far better than video as can include what to watch for etc: http://netwelding.com/Engine_Cover.pdf
Third Pic on page two the caption states:
Only use a wrench to loosen each bolt a few threads. Then use you hand to remove it completely and put it in a safe place. YOU DON’T WANT TO DROP A BOLT!”
For a DIYer like me doing it once always things to screw-up that I include! Yep 5 pages of Pics but worth not screwing around looking to buy a bolt dropped and lost!
That PIC caption in full said: There is a hose on the left engine side that can be easily removed from its clip. Then loosen the four 10 mm bolts holding the engine cover in place. Note they are not very tight, relatively low torque required. That is what should be used when reinstalling! Only use a wrench to loosen each bolt a few threads. Then use you hand to remove it completely and put it in a safe place. YOU DON’T WANT TO DROP A BOLT!” I dropped a screwdriver and it did NOT fall on the ground! But was easy to retrieve. A bolt might not be so easy!
Jerry, funny you should mention "Dropping a bolt". A friend of mine with a C8 dropped one of the rear strut brace torx bolt all the way down to the bottom shear plate. Four hours later after dropping the shear plate the bolt was recovered. Bolts that are dropped don't just fall to the ground like on previous Corvette models. Be careful!

Bottom of 3 Pics, Caption on page 10 starts with: "Note reason for rag. Just in case you drop a bolt or nut! Instructions say “note torque needed to remove bolts and nuts....." Finished Install!
When I painted my engine cover, I bought some stainless flange head bolts. Same for the valve covers.
In theory stainless is not as strong as steel, but still plenty strong for an engine cover.
Not sure where I bought them, probably Amazon, you know free shipping.
Bolt size needed
