2 Questions about the SR: EM Gasket & Igniter chip

[rocksteady_racer]

Ok my first question is I just got my exhaust manifold off and the gasket that was on there was stuck to the block and fell off in pieces, it's the stock nissan gasket. How do you remove what's left on the block and intake manifold? Do you use a metal grinder with a metal brush or a light grain of sand paper?

Next question. Igniter Chip. Is there any way to replace the igniter chip with something else like an MSD ignition or something? I've heard they break all the time and I'd rather have something that lasts longer. Thanks in advance.

maybe a razor
scrape it clean

ignitors dont break all the time
thats a lie.
most my friends have had swaps for at least 5 years adn on the same ignitor
ive been using mine about 2.5 years now. its perefectly fine
save ur money.

^^ i agree with dousan i recently had to do my exhaust manifold gasket and i used a razor blade to gently scrape the gasket pieces off.. and a little varsol on a clean rag to wipe away whatever's left.

Careful with the razor blade not to scrape too hard, you don't want any deep scratches or anything. Make sure the blade is flat against the surface and gently scrape away at the leftover gasket pieces. good luck!

All the ignitor chip is, is a big relay. When the ecu grounds, the ignitor acts as a relay to send 12v + to the coil. Thats it.

They are damn near bullet proof.

i just use a ziz-wheel on the gasket. not sure if you have access to an air compressor. if not, use a razor or a gasket scraper.

I have an air compressor in my garage, what kind of attachment do they have for that to make it easier?

[johngriff]

razor blade and 10 mins, its so fast.

I used a putty knife, brake parts cleaner, and fine grit sand paper to clean the old gaskets off my manifolds.

Removed most of the large chunks with the putty knife and then cleaned off the burnt on parts with the sand paper. I used the brake parts cleaner periodically to clean off the surface and remove any gasket particles.

Razor blade works, but you have to get it at the right angle and it's really easy to dig into the aluminum block.

Used the same method and it worked like a charm.

DO NOT i REPEAT DO NOT USE A ZIZ WHEEL. For the 45 seconds you save using it it is not worth putting a big nick or cut that will leave you with a leak. -rep 4 you sir 4 posting info that will fuck up his head.:bash:

Yeah, don't use power tools to polish these surfaces unless you're sure you know what you're doing.

At those speeds it's very easy to create uneven surfaces resulting in peaks and valleys (read: leaks).

good info from a fellow zilvian: project_s13

"""but with sharp blade be carful not to gouge the aluminum block. another technique that works extremely well for me is find a large flat low grit file. one thats about 2 inches wide about 8-12 inches long. run it along the top of the bloek being carful to stay flat on the block and dont file the edges. go back and forth on the block not legth wise. and dont use a whole lot of pressure. it will do its job. spray some deep creap or some fluid film on there with it. it will help. maybe some gasket remover aswel. clean it up then use the file. thats the way i go. the file will also remove and burs and what not from the block. which is nice for a new headgasket then you know you have nice sealing surface. ALSO make sure your dont file in one area for long period of time. ALWAYS keep mooving as a steal file will eat aluminum quickly. IF IT CONTINUES to be stuborn go buy a 3m pad from paint store or parts store there about 4x5 sheet i use red grade. it works well also. but again being sure to not press to hard as it will eat aluminum. when its shinny ish its done"""
