When things go right, the layer of Loctite that remains between the two halves of the block will almost be invisible....extremely thin. There will be a thicker layer along the perimeter, where the two pieces of metal don't actually touch, but it needs to have squeezed out everywhere else.
Your layer of Loctite is certainly too thick, which means there wasn't a good squeeze.
Only a few choices, which I discussed previously:
Never remove the old Loctite with anything but a razor blade, acting like a scraper, held perpendicular to the surface.
Never, never , never touch aluminum surfaces with one of those "Rotary Scotch-Brite pads....regardless of which one looks like it will work! I don't care what your buddy the "professional mechanic" does when working on a Toyota at his shop! Never try to use any power tool!!!
Any tiny "ding" that the razor blade hits needs to be gently filed flat. Throw that razor blade away, when you hit one of these and get a new one. Never buy .009" razor blades! Only .011 blades. The .009" ones chip and scratch too easy.
Old Loctite (has to be really old....way past the date with the "toothpaste" style tube. I have found the shelf life to be much shorter with the "accordion style" tube. (I will not buy it, in this style tube.)
Layer applied too thick. Go to Home Depot paint department. Buy their super short nap roller with the plastic handle. Comes with a clear top and a plastic tray. If you don't know the one, I can take a picture. Squeeze out about 1/3 of the tube onto a piece of plastic. Roll until the roller is fully packed with Loctite. You may need to use 1/2 tube the first time you load the roller. When you apply it to the cradle (only the cradle) it should look thin....with little tiny bumps from the roller nap.
Install the cradle...but don't push the two parts together until you have started all the 12mm and 10mm hardware. (It will not start to cure until there is a lack of air, so use that to your advantage.)
You should have all of the hardware and all of the tools ready to go. I use a low power Snap-on 1/4" air ratchet to run all the 12mm and 10mm nuts on...as quickly as possible (this tool does about 16ft.lbs.) Start with the 10-12mm nuts in a criss-cross pattern and then doing the 12-10mm nuts. Forget about the torque....run them on. Now run the 8mm hardare in with the same tool....all of it....including the ground strap. If you watch the edges of the cradle, you should see the Loctite squeeze, first with the big hardware and then a bit more with the 8mm hardware. Now go back and torque the 12mm and 10mm hardware to full torque, through the stages. Finally, torque the 8mm hardware.
When you are done, you should be able to wipe off the excess Loctite all the way around the outside, leaving no residue. If there is a pink radius of hardened Loctite and you followed my proceedure, the Locktite was bad and you need to do it again.
Immediately remove the oil pump housing and clean up the Loctite that squeezed out, inside the oil pump cavity.
Any questions, class?
