What bolts to use Thread locker on.
What bolts to use Thread locker on. Starting my build today and a little confused on which bolts to use thread locker on. Mains/Rods/Heads etc. All previously stated bolts are all ARP. Should I use ARP lube or Blue thread locker? Should I use thread sealer instead of thread locker on head bolts etc.
Im going to sound like a jerk, but I don't think that you should be assembling an engine if you don't know where to use thread locking compound on an engine. In the sbc you only use sealant on the head bolts. The Ross and mains should be done with arp lube and torqued to arp's specs. You should also follow their recommendation on sealant for the head bolts. This way you know it will work. I have only used thread locker on small parts that get higher rpm or vibration. The ign rotor is one example. I have never used locker inside of an engine though.

^^^ Im going to sound like a jerk but......is there another way to learn other than by Reading, asking, and doing? If you still have the "I know everything about everything all the time" program you used can I borrow it? Ive done extensive reading and studying on the LT1 motor. I've been on this forum almost everyday since 2006, and only have 1XX posts. Wonder why? Its called the search tool. But if I dont find the answer using that, guess what I have to ask. Seems to me that people would appreciate the fact that someone wants to learn more and actually get better at something they enjoy. In my lifetime ive learned you can ask ten different people the same question and get about 7 different answers. I take the information given and then make my own decision as to the the route I will take. Ive got to ask questions if I want to learn.
Really dont want to sound like a jerk either.

BTW sorry for the rant. Just found out one of my splayed bolt threads let loose and put a screeching halt to my build right before I read your post. But really thanks for the info. Just feeling a little

As said, arp lube on rod and main bolt threads and also under bolt heads,washers and at the surface under the fastener itself and torqued to the manufacturer spec. If using stock bolts the torque values will be using motor oil.Head bolts Arp thread sealant at threads and Arp lube under washers and bolt heads. I like to use blue loctite on the cam retainer,oil pump drive and spider plate. Oil pan and timing cover just a tiny bit of oil on the threads. And anything that threads into aluminum gets a little anti seize. If using Arp flywheel and balancer bolts Arp lube on them as well. If rocker studs hit water then Arp thread sealer,if blind Arp lube. Hope your block threads don't cause you to much trouble.

I used blue thread locker on the oil pump drive bolt, a drop on the cam retainer screws and cam sprocket bolts.
Just keep in mind the strength of the various grades of thread locker.
Red, difficult to impossible to remove without applying heat to soften the compound.
Blue, hand tool removable.

Good Luck, and hopefully it works out for you. But if you don't feel comfortable repairing it, definitely have a machine shop do it. It shouldn't cost much and there is no extra machine work to do because of it. \
*and the idea behind the advice was to keep you from spending a lot of money down the road should you make a mistake, I hate hearing about guys that forget/mess up something seemingly simple and it costs them a multi-thousand project.*
