so im finally starting a thread on my 78 b210

[triiodide]

First things first my name is kyle, 19 years old, love anything with an engine, i go to MMI the motorcycle mechanics institue here in phoenix, So anyways i picked up this old beat up jewel from my uncle about 3 months ago when my fzr600 threw a rod.

Cant lose for 500 bucks!

And anyways it has been a wonderful car that I've already put about 8000 miles on, until bang, backfire blew a chunk off my intake manifold, which turned out to be caused by a previous problem, so the teardown begun

[Guest roseyroseyrose]

hi there....cool car.....ratsun is fun, youll enjoy it here!

[triiodide]

so first.. thank you very much izzo for the manifold :)

And then it starts....

AHHHH! Vacuum lines!

[triiodide]

So after a lot of sweat and swearing, and a lot of little baggies lol

It turned out the manifold must have been torqued down improperly. So when the backfire occurred

Alright! Two cylinder on our hands hahaha

[triiodide]

And well Im at the last Lego block before i pull the manifold, uhh egr valve i think?

There's the fitting anyways, i want to just leave the pipe there, and pull the manifold right up, now i have a question for a few of you folks, i want to know what surfaces it is okay to seal with a type of sealant.. my friend recommended an aviation gasket sealer that he said would work really well, what parts would it be okay to use such a thing on? If any

[RedBanner]

Welcome. Love the coupe. Never seen an intake brake while driving. "DANGER TO MANIFOLD" member title needed!

[RedBanner]

No selant should be needed on intake. But if you do use some use permatext, and do your self a favor and only coat one side of each gasket.... shit is tough and my refuse to release later lol

[triiodide]

Alright haha, i just don't want any horrible intake leaks.. considering I'm reusing some gaskets and making others out of gasket paper, and any tips on torquing the manifold to the head and to the exhaust? I think my manifold was cracked and that's why it blew off, don't want to mess anything up lol

[RedBanner]

You realy need to get a feild service manual. A nissan one the others wont do. Each item has a differnt torque requirement. And tightening sequence. A f.s.m. is around 20$ online used, but will save you so much headache, rework, and money you wont believe it.

[triiodide]

Oh yeah, i didn't get a picture of it but there was a screw sitting on top of my heat riser lol

[RedBanner]

Dont reuse or make the intake/exaust gasket to the head. Never works right, because of the shared studs and joined manis.

[triiodide]

Oh i do believe it haha, but would you by chance know the sequence? At least manifold to head then to the exhaust right? I think it had previously been tightened all the way to the exhaust and then they cracked the manifold tightening it to the head, that's what i think anyways

[triiodide]

So i gotta rip the exhaust off too? :/ i wanted to avoid doing that but i guess i have to, cant i just use a little bit of sealer on each one haha i really dont have many options because its my only form of transportation at the moment and am borrowing a car, if its quick, and it runs, it'll do for me

[B210GX]

Yes remove the exhaust too,  You can probably get away with just moving it aside..... If its worth doing,  Do it right

 

Love the Patina'd finish on the paint too.   

 

Did someone add to that rear bumper ?   it looks UN normal . I dont believe I have ever seen the corner pieces protrude behind the steel like that.

 

 

 

EDIT:  is that a third brake light below the louvers?

[triiodide]

nope, that is just a reflector and i'm not sure about the bumpers, they match front and rear though, this car has a few dings and dents, its been a bit beaten up, all on the back though lol, and i guess i'll be ordering that gasket and doing it the right way. can you unmount the manifold and move it over far enough without getting under the car at all? i don't have access to a floor jack right now  :hmm:, and are there any other bolts for the center of the exhaust other than the top and the two that also hold the intake?

[KELMO]

On an A motor you can take both intake and exhaust manifolds "off" and not have to get under the car.  By off I mean they will move to the side enough so that you can replace the gasket.  Be mindful of the "yokes" that help hold the exhaust and intake together at the bottom...they are like thick washers and if lost would take some time to order in.  I could not find any info on torque specs for the manifolds (its a haynes manual WHAT did I expect) so, here is my 2 cents worth.  I usually start at the bottom in the center....get the nuts hand tight there then the center 2 on top at the intake then work my way out from there.  Once all are hand tight I start tightening in the same sequence...from the center out

 

Hope that helps

[_k_i_d_]

Cool!  What kind of wheels are those? 

[triiodide]

Alright thank you, i realize how easy it is now that the manifold is off haha

[triiodide]

The third broken off piece blew off with the backfire and it is absolutely nowhere to be found, the stud was blown out and laying on the manifold before i took it apart. Thanks a ton on the sequence advice :D now one more thing, the manifolds are slightly different

See there are a few fittings well.. not there, the brake booster one fits in the back driver side of the manifold and had a capped off line so that's taken care of. But I'll be losing one on the front close to the head, not sure how to handle this

[triiodide]

Here's one more pic of the front of the car

[converted_to_datsun]

Nice car dude! :thumbup:  The b210s are quickly becoming a favorite of mine, take a buffer to that paint and it'll shine. Keep up the good work

[triiodide]

Yeah haha you can actually see a little part my brother put a little bit of some compound, not sure what it was and wiped it with a rag and wow, the paint would come out fantastic if i did the whole car, just gotta fix it first haha. And i have no idea what rims those are other than that there 13s

[B210GX]

does the car have to pass smog inspection?   if not, dont worry about the front  vacuum line.

 

The wheels appear to be the backs to the fake spoke wheels seen on "Z" cars  back in the day..

[triiodide]

one more thing about those rims, the studs have adapters on them with gigantic lug nuts lol, and yes, i do need to do emission testing :/

[triiodide]

So.. here's my issue, as i get the manifolds together... well absolutely nothing i do will make them line up properly, i get them mounted together and they won't even come close to matching at the head, and if i try to get them to the head individually the heat riser and everything else is like a half inch off! Do they need to match? Am i doing something else wrong?
