Due to the police im not going to be able to drive my car. for how long i dont know but i want my car in perfect conditon so when i am able to drive it again i wont have to worry about anything major.

car is a 90 gxl with 73ks orginal miles.

what i wanted to do first was rebuild the engine bay so see what need to be fixed. can i unplug everything in the engine bay and put it back together without any disadvantages? im talking about pretty much everything connected tot he engine. vacs, wires, and manifolds.

If you're going to be taking stuff apart you may as well replace stuff while you're down there.

common stuff to replace/inspect:
-all vac lines
-all water hoses
-change all stock hose clamps to worm gear type
-new gaskets

rebuild the engine bay? like clean it up and make it all pretty? just get the handbook, some masking tape and a good pen to label everything, better yet get a camera or camcorder and get it visually.

darksider

sorry i was at school and they closed so i had to get out of the library and couldnt finish the post. i wanted to ask what i could take apart on the engine and put back together without messing up the stock compression/performance . thanks

Are you trying to rebuild, repair, fix, etc. while you can't drive it, or just preparing to store it away until you can drive? If you are just putting it away, leave it alone, and start it once a week, and let it run. Put it on stands to take weight off tires, and check the FAQ, and archives above. Incredibly amounts of information on both angles.

what im trying to do is get the most out of my engine (plus reliability) with stock oem parts. i just wanted to know what parts (manifolds/vacs/wires) can i take/unplug/unblot off to repair/polish//clean with out messing up compression or cuase major damage that would result me in buying new parts. i hear if you take apart a stock engine it doesnt retain stock compression/performace. i think it was due to the gaskets/seals not sealing the same.


thanks for the repies

to ilike2eatricers

would you recomend me replaceing the gaskets for the engine too? or just exhaust and intake? would replaceing the gaskets on my stock 73ks engine make it last longer?

Mombodogs

I commend you for taking such pride in your engine, and if you really have that much time and money, rebuild the whole thing. If it is a 90 with 73 thou original miles, no smoke, no leaks, good compression, idles and runs good, you can do anything you want to without damagine your current status.

However, if you really are going to go to that extent, I know I personally would rebuild the whole thing. Do some serious searching about porting, rebuilds, intake, exhaust, etc. There are some great horror stories, as well as countless successes on the whole matter.

It would be a great learning process, like I said, if you got the time and money. Where are you located? I like to come watch and learn some more myself. I have a 90 FC3C, n/a, and would like to see a rebuild first hand. Im near SF, CA. Im guessing your in CAl also.

I just couldn't resist, but you've got to elaborate on this. When I read this, the first thing I think is "That really should read, Due to my OWN actions, i'm not going to be able to drive my car", but since you didn't provide a story, I dunno if it's true or not, and it's driving me nuts wondering if I should bash you for blaming police for something you did, or if I should feel bad and help you!

Mombodogs

RaT, love the new avatar. darksider, I knew your name was familiar. Where's the car? At school, or up here at Marine World? We will talk again.

PEACE THE DOG

the thread says ONLY help if you want to!

does it matter what happend to me with the police? i just wanted help on my rx7 and i thought this was the place to go. isnt this rx7club.com??? i might have missed the sign that said "you can only get help if we think you deserve it." daym i knew it was too good to be true...

to momnodogs

the car is here with me in san diego. i think ill be down there for the holidays maybe we can meet up. ill talk to you later about it but now i need to know if replacing the gaskets (all gaskests and seals including engine) will make my engine last longer. im trying to stay sway from a full rebuild for a while. thanks

ohh i notice that theres a couple of tubes that are disconnected in the engine bay. i routed it back to he big tank thing in the coner of the passenger side struct tower. it seems to be leaking coolant or green liquid. care to tell me what this is and where i should plug the other end of the tube to? the tank has two tubes on the top and one on the bottom. the tube on the bottom is disconnected. can someone show me how to post pictures so i can just show you. thanks

NZConvertible

That's the Sub-Zero Start Assist System. It should all be removed (on Mazda's advice). You can remove the tank and just cap all the disconnected hoses, or you can remove the injector on the manifold as well and replace it with a block-off plate.

Now that I've helped, I can say what I want...

You don't actually get to decide what gets posted in a public forum. Comments like that tend to irritate people.

It obviously does to you judging by your touchy response. If it bothers you, you shouldn't have mentioned it. Your comment was bound to attact attention, because it's rarely the police's fault that you lose your license.

Actually if you read the FAQ I think it does actually say that. So be nice...

If you want to get really serious about detailing your engine bay, you can strip out everything that is bolted to the fenders and firewall and strip the engine down to the bare block. Depending on how far you want to go and how much you want to spend, you can, paint, polish, or powdercoat the removed parts and repaint most of the bay itself.

While you are in there, replace all vacuum hoses and rubber cooling/heater hoses, flush and fill the cooling system and change oil.

Scrape off the intake gaskets and block the intake and exhaust ports to keep unwanted items out of the engine. Squirt some MMO in the intake, turn the engine over and tape over the ports. The engine will be fine until you are ready for reassembly.

Make sure you have at least a Haynes manual on hand and preferably an FSM too. Take pics before and during and after disassembly. Then post the before and after pics to show off your work.

It's encouraging to see an owner who wants to restore thier there car. A nice change from how do I shift mad tight yo and can I drift a 7.

No doubt NZ, if I didn't see the 'due to the police', I'd of just continued on helping, but saying something like that either means you're inable to accept your own responsibility, or you got screwed by them, and judging by the response I got by asking, well, I'd guess it's the later. And in that case, I'm not going to help simply because if you learned it was your own fault, and tried to change whatever it was, you wouldn't blame the cops.

Hows that saying go.... if it aint broke? If your car is running now, why even mess with it? It doesn't sound like you are too mechanically inclined if you are really scared to screw something up and not be able to fix it, so why even bother?

Then again, you can use this time to download the fsm, buy the haynes manual, and learn about your car.

Ahhh , usually that's the reason for 'police downtime' these days. crazy kids

darksider

thanks for all the help. i guess i got what was comming to me and if i could edit that post i would. but anyways back to the point.

i notice there was still coolant (small amount) comming out of the sub zero start assist system. this must mean that the unit is still working or running. if so then why is it not important? im thinking it has somthing to do with the ac but i want to know for sure before i remove it. i still have my ac and ps so should i keep it even though it rarely gets below zero here in diego. thanks

Mazda issued a tsb years ago, instructing the dealers to remove them. I was under the impression that the CA models did not have the sub-zero system, due to the stricter emissions there. Most of them rarely work anymore and you really don't need it in your climate. I would remove it, personally.

darksider

im just aking for help and i would still be greatful if you did. if you dont then im pretty sure someone else will. thanks anyways. KEEP THE PEACE

Stock compression from Mazda can be IMPROVED ON with a good rebuild on the engine. Things to do if you have the time:

-Replace ALL vaccum lines / hoses in the entire engine bay.

-Make sure all wiring is fully wrapped / protected from the elements.

-As you remove parts, to get to hoses, CLEAN them before putting them back.

-Clean the actual engine bay while you have the parts out.

Now..I'm not trying to be mean, as I am obviously willing to help in anyway I can..and I don't care if it's you're fault or not, but I would actually like to know why you can't drive you're car. I'm not going to bash/flame/blame anyone or anything, I am just simply and purely curious about this matter. It's always nice to know what to avoid when I finally get my license in February..
