OK my Buick Homies and Gurus, I'm about to replace the timing chain on my 400 (1969). When I removed the timing cover to replace it, I notice that the timing chain seemed kinda sloppy (it is not original). for piece of mind, I decided that for another $60, the Melling set (chain and gears) was well worth it. I have a couple of questions that I could not find the answers to with the search feature: Should I use thread-lock on the cam sprocket bolts? I saw in the manual that they get torqued to 22 lb/ft. Should I soak the chain in oil before putting it on? Any other helpful hints would be greatly appreciated. Thanks in advance for the advise!
I soak the chain in oil and put thread locker on the bolts. Nothing magical but I imagine others here have varied procedures that may be better.
When I did mine on my tiny Buick V6 I did blue Loctite(242) on new ARP cam sprocket bolts. I also coated the sprockets, cam sensor, gears & such in assembly lube. Kyle
I've never used loc tite on any engine fasteners except the tiny bolt for the oil pick up tube. I've never soaked my chain, I install dry, its way less of a mess, especially when you degree your cam. I oil the chain after the final install, no issues.
