Head Gasket change

[Guappone240]

I just got a 240 and Im trying to change the head gasket. Now to make sur the timing chain stays I have to put a wire or something that i can pull back out fromon side of the links to the other by the crank so it doesnt lose its timing right? But before that I have to make sure cyl. no.1 is all the way up. How can I tell its like that. and if I remove my manifolds off the head I have to replace the gaskets or don't I? just trying to make sure I understand what Im doing.

Whew, here we go bud. Alrighty, the point of tying the timing chain up is so that it doesnt fall down into the front timing cover, thats it. Your going to have to find TDC and put it back in time, I personally use a long screwdriver in the spark plug hole. Use the timing marks on your cam gear's and your crank pulley. I would for sure change the gaskets on your manifold's, they're already off so you might aswell. If you need anymore help just ask.

I see thanks for the help.

This is what I have been looking for. I have to replace my head gasket... or at least I think so. I hope its not a cracked head but I will have to see. I do need some help and I happen to uncover this old thread. Maybe I can get this baby rollin again and people can offer me great help from around the globe!!!!!! So let the advice flood in!!!!!!!

this is an old thread but hay..since we are here....

#1.) exauhst gaskets...use copper or aluminum ones..they are reusable!.

#2.) you can make your own gaskets from rubber celluloid type gasket material..you can buy it at any parts store for about $7. bucks a roll..just make a patern by a rubbing tecnique...ie crayola and some paper..then cut the pattern out with a razor or what have you..and then trace in pencil on the gasket material..cut out again..easy and cheep!..best of all..you can do more than just an intake if needed ...

as for a head gasket...if you go cheep there..you get cheep'o results..but a good one and follow directions.

[Dr.Noisewater]

Thanks for the help and I Have heard good things about the Multi Steel Layers (MSL) gaskets. They have rubber on them that seals it self to the block is that true and would that provide better strength compared to a copper one? I do plan to boost if that helps any.

Wow can't believe my first thread is back agian...anyway. Don't go cheap on head gasket. I got a kit for 35, everything included, amd now I think I'm paying for it. I don't know whether it's really the gasket it or not. But I know it's my head. Oh and the bolts are tourque to yeild.

[Dr.Noisewater]

Well I plan on a Mr. Gasket set but I'm still looking around. I just want something strong but dont we all!

[Dr.Noisewater]

Requesting more detailed info on removing my intake manifold. I own a 91 240sx KA24DE. I have a blown head gasket (I Assume) and would like to change all the gaskets on the car as I replace that. Thus far I have removed all the bolts and the intake mani is still not moving!! Any help guys???

[Razi]

Check the pictures in this thread:zer...ionsl

Then make sure you got all the bolts undone.

[Dr.Noisewater]

lol I have been lookin at that thread for hours. the black Y shaped bracket that comes off correct???

[Razi]

Yeah it should.

[Dr.Noisewater]

Okay thanks i want sure I assume that might be whats keeping my mani from movin. Will you be on long I'm in my garage now I will probably need more help if possible.

[Razi]

I have to be out in a few minutes, but if you have any questions just post them and I'm sure someone else can help you.

I'll be back soon though, so if nobody's helped you by then, I'll chime in and see what I can do.

[Dr.Noisewater]

Thanks so much I will get to removing that bracket and see what happens!

[Razi]

Alright, good luck.

[Dr.Noisewater]

So yeah... I removed that Y bracket and I cannot get to the "inside" bolts on the upper part of the intake manifold. I totally forgot about those any tips maybe?

[Razi]

Try using wobble extensions to get to the hard to reach spots.

[Dr.Noisewater]

Okay I will see if I can get some. It has been hard using ghetto extensions. I have another question about my ERG Pipe that is keeping me from removing the exhaust mani and pipe. I cannot get that thing off and tips? I'm currently asking another guy I hope I have not asked you yet.

Dr. Noiswater....there are really only a few reliable head ghaskets that you wont have to pray when boosting..

#1. commetic..mid range boost#2. SCE..i use this..they sell multilayer or full copper...full copper...high boost..from 20 to 60psi and beyond.#3eom nissan..for low to no boost.

hope this gives ya a better look at what ya might have planned down the road with your headgasket woes.

[Dr.Noisewater]

Thank you Liquid. Now I may not be boosting in the 20+ psi rang but would it be an issue to use one for a for low boost application??

[liquid_cool]

there wont be an issue with a multilayer gasket...as for copper gaskets used on the head..you will need machine work and you have to choose the size of the gasket carefully...the machine work involves (O)-rings around the cylinders and a reciever groove on the head..you can look it up by googleing it to get an idea of what im rappin about..

[Dr.Noisewater]

I looked up some info on both the MLS gaskets and the Copper ones. The copper is cheaper but is it as strong as the MLS ones?

[liquid_cool]

full good copper head gaskets are heat treated and run 60 to 80. bucks..they are stronger than multilayer..but requier machine work to be done..the copper gasket allso gets a perfect seal..as the material will form to fit any imperfections the head and block may have.

[Dr.Noisewater]

Oh okay so I would have to buy a copper one that fits my model and then have a machine shop match it to my head? I assume this would be a good time for the shop to help me with any cylinder head issues too.
