Hey Guys, I'm ready to install the intake on the 383. I believe I buggered it up last time. Can you give me guidance on where to use sealer or gasket adhesive? Heard a few ways to apply the sealer, from on the head only, to between every surface and valley pan. What have you done and what works? thank again. Btw, got the silicone on the ends understood, just need info for the gaskets and pan.

i put the gasket sealer on the intake gasket, then place it gently onto the engine
then, just bolt on the manifold

On the 383 it has a gasket-valley pan-gasket. SEalant on which surfaces?

i put the sealer on around the openings for the passages on the valley gasket

scotts74birds

OK, thanks. Intakes always kill me. This time it was a cross-threaded intake bolt.

how did it turn out?

scotts74birds

Not well. I tried using a tap to chase and clean the threads, then used a bolt and spacer to simulate the intake. I tried torquing it to 25lbs, but there wasnt enough left to grab, and stripped out completely. I go back to work an Monday, Im sure the toolmakers will have a helicoil to help me. Thanks for the help.

i use white three bond & just like loc tight the less you use the better . is this a stroker scotty ?.

scotts74birds

Theres just not enough left to bite into in the head, do you mean to use that on the helicoil? No, its not stroked yet. I just need it running to move it around the property, and get other cars in the garage for small repairs, also to some folks places that might help me with the roof. Need to strip, grind and sand. Dont want to do that in the garage and cover the Harleys and everything with ****. I'm a bit picky about having a clean shop.

no not on the helicoil , basically it's liquid gasket i usually put it on the head surface to hold the gasket down so you can take the manifold off at a later date & the gasket / pan stays put .

Got ya, sorry, had a blonde moment. I'll do that. Gotta get to the speed shoppe this week and get a new gasket, carb gasket, and other bits. Maybe look for a linkage set-up that will work too. do you put the sealer on the pan side of the first gasket, or just on the head?

deadkelly

i think its 3 bond on head -valley pan -intake gasket . its up to you weather you put it on the manifold if its not coming off for ages yeah .

The bolt hole on the head striped out? I know that it would be a lot of work, but do you have another head or set that you can install? I've never been a fan of helicoils.

Update. Got the helicoil from work today, bolted the intake and used it to guide the 25/64 drill bit for the stripped manifold bolt above #7 cyl. Lined the lifter valley with rags to catch the shavings, coated tap with thick grease to catch the chips while threading, vacuumed the area for any missed chips. Inserted the coil per directions. When done I used a 5/16" punch to break the tang on the bottom, just some light taps said the toolroom guys. No problems. I got an intake bolt and stacked washers to simulate the manifold thickness and torqued to 25lbs. No drama, held fine.

Thats good.

I'm finally ready for attempt #3 at getting the intake sealed, Eddy performer RPM. The first 2 times I used a Fel-Pro kit #1214 that had the valley pan and 4 paper gaskets because that is what the old intake had. This time I,m using a Fel-Pro #MS96007. It is just the valley pan in the kit with no paper gaskets. The construction of it is thicker and slightly different from the valley pan in the other kit. but they are both for the same application ['70 383]. So I am going to use just the pan, NO paper gaskets as you guys recommended. I now open the floor for suggestions on what sealer to use on the intake ports and whether to use it on the head, intake, or both sides. I will await the collective wisdom of the masses. thanks guys.

mate i have a fel pro intake manifold gasket 1214 1961-78 . this is a exhaust cross over BLOCKED OFF valley pan . i think i farked up last time because i used same pan + paper gaskets as well ???? . i think the inlet manifold was sitting a bit high ??? . so should i just be using the VALLEY PAN ONLY with liquid gasket sealer ???? i will use ( white ) 3 bond liquid gasket on block ends , head , & on top side of pan then put manifold on ??? . i think that should be right ????? any advice appreciated thanks guys & how did yours turn out scotty ???????

scotts74birds

Thanks Dead. Dont know what 3bond is, but I went with the MS96007 valley pan and the permatex "Hylomar" this time, and NO paper gaskets. With luck I will be puttin-the-match to it tomorrow. Gettin frustrated. If this aint it, then something has been shaved. and I dont know what it might be . Heads or block. Gaskets, sealant and paint is all the budget allows for now. This time the bolts went in better than ever, or is that because I've worn them out! HaHa! Stay 'tooned!

I'll stay tuned for sure . mate 3 bond is a liquid gasket that is used across the board over here . every bike shop uses it . most jap bikes don't have crank case gaskets . they use this 3 bond ***** . it's $40 bucks a tube so it would want to be good . every one over here uses it . it has jap writing on the box . & you can get different colors for different uses , we find white works well on most things . at the bike shop i worked at it seemed all the ruff & bodgie people seem to use ( to much ) blue silicon . so i stay away from that in case its contagious .

scotts74birds

dont get me started on the "blue silicone' as the fix for everything! I pulled the 73 shovel apart in my 53 rigid, and the blue stuff was everywhere! Oil filter too! Clogged it up but good. Found it in the oil pump too!

HMMM don't know which is worse...sillycone, or the 3-M 'monkey snot' (weatherstrip adhesive) lol
