Headgaskets and Intake

« **on:** June 27, 2014, 10:58:21 AM »

Hello fellow members, I got a question. I tried looking online but couldn't find a steady answer. I'm replacing my head gaskets and intake gasket due to some milky oil. My question is, do I put some sealant on all head bolts? And if so what type of sealant? Also what's the torque sequence and specs. My other question, do I put silicone on intake gasket too? Thanks in advance guys and sorry if its a dumb questions

what motor? when i assemble heads i put thread lube onto the bolts and i use permatex sealant on the ones that go into water passages. thread lube helps with getting a proper torque rating on the bolts. before all of that ill also run a thread chaser down just to clean up the threads and remove any old lube/gunk.

i put a SMALL dab of silicone around the water passages for my intake manifold gasket. they usually dont require it if you're using new parts, but older stuff has some pitting usually around the passages and its just a little bit of security against leaks.

Sorry, BBC 454.
Will this work for the ones on the water passages? This is what my machine guy said to use.. and what do you mean around the intake water passages, got pics?

i could recommend NOT to use that. pipe thread is a compression fitting... if you look at a pipe it starts small and is angled. as you tighten it, the 2 pieces wedge together and make a seal...

So use the "arp" lube on the bolts with no water passages and that red loctite on the bolts that have water going thru? Sorry

Hey Ka0tic, I couldn't find that water jacket sealant. This is the closest I found to it. Would this work?

Not to high jack, but the permatex is rated for that as well- No experience with it though.

Though I would use what dat1dsm recommended. Also the ARP is good stuff but research the bolt/stud with Arp vs. oil or any substitute as sometimes it is 2 different torques. You can get both on Amazon- Got a prime acct and get stuff in 2 days and Sat. Well worth it- Plus Movies!!

What did I recommend 240?

Don't use anything that says "thread sealer" on the tube. Use ultra black...sparingly.

Sorry meant to say what Ka0tic recommended-
That being said I've seen motors with nothing but Ultra Black, Ultra Grey and as well and they sealed fine, used it on all my triumph race motors. You have many options and they will work-

Didn't get to take it out today. Had problem with intake gasket. The ones I ordered off summit didn't work. Not sure which ones I need. If anyone has any advice I'd appreciate it. Thanks

Thanks Ka0tyk. Do I wanna block off the square ports?

« **Reply #23 on:** June 30, 2014, 11:40:55 AM »

for a jet boat you really dont NEED them. but its not gonna hurt anything if you run it open. most intake gasket sets come with the restrictors.

Is that what those Lil white square things are on that picture?
