Honestly its bone dry out here for parts man, I've checked out every scraper in my area and even begged a couple people to sell me theirs off there car cuz they weren't driving it.

Ok well of course problems come in three's soooo, as they sit right now I have no wipers, a leaky gasket on the exhaust side of the engine along with a crack exhaust manifold, and I electrical problem. The car doesn't want to stay running unless you rev it, its like its not getting power. I took the alternator off and got it checked out, it was good (better be cuz its brand freak'n new!) and I'm skeptical on the battery being the problem but all I can do is hope that's it.
Also looked into maintenance which I'm surprised I didn't do yet (other then an oil change). Found that my spark plugs we're beyond done, and the crush washers we're sealing anymore so oil gas and carbon had formed a crusty paste in every spark plug port and my plug wires were so old the bottoms had decomposed (forgot to take pic's). So far I Clean all the spark plug holes and replaced the spark plugs, cleaned the distributor cap and check to make sure that part of the system was in good working order; so now all I have left is to replace the spark plug wires.
Also looked into my intake system and was blown away..........how my car ran as good as it did I cant fathom! From the filter back was just gritty and slimpy. So I pulled the intake system up to the manifold and started cleaning.
Heres what it all looked like:


Then I got an idea.......why not polish the MAF housing to help with air flow and make it look better, so that's what I did. After 10 hours of wet sanding with 400 grit and 800 grit metal sand paper and the polishing here's how she looked.



Still not totally happy with it so a revisit will be in order down the road.

thats some nice work on the throttle body. damn i kinda want to try that out now but i don't have a 5m of my own anymore
the manifolds would be a project. how many hours for the TB?

I haven't got to the throttle body yet, I'm focusing on my intake mani right now so I can get the gaskets all made up and re-install it before I forget what hoses go where haha. I'll take a couple pic's then its done and post them up.
So the 7m's have totally different MAF housings? I must look this up.....

Also I found that my valve seals might be gone....I came to this conclusion when I cleaned the exes dirt and gas from the intake manifold. It dried and I noticed what appeared to be a lot of carbon build up inside, looked exactly like the exhaust valves on my 4g63 head......sooo if the head gaskets gone (will find out then I pull of the exhaust mani) I guess a head tear down will be in order.

Quickly started the throttle body tonight...... what a PITA, worked on it for the length of a top gear episode and said screw it Im off to bed!


once again not at all happy with it and I didnt even start on the outside of the TB cuz there to many small spots I wouldnt be able to spiffy up so itd just look like crap.

Got everything back together today and went to start the car..........it burst into flames!
I would have took pictures if I hadn't been so busy putting it out, have no clue what went wrong never had something like this happen to me before at all!

It burst into flames. Are you leaking fuel? I have a degree in automechanics so, if you give me some more detailed information. Maybe I can help you figure it out. such as did it back fire. This helps rule things out.
