Vacuum Line Problems

[martin_skip89]

I have 1982 Supra with a basic I6 Engine in it.... I just bought it off of a guy that had it sitting around his place for a few years. When I bought it, he told me that the engine was running a little rough, and that it wouldn't start. Well for the engine, all it took were new spark plugs. As soon as it fired over, it ran rougher then I imagined, come to my suprice, alot of the vacuum lines were bitten in half by mice. Now im to the point where I need to find a vaccum line diagram for the car, but have had no luck yet. If you could help me out that would be great. Also, while running rough, there is alot of smoke that is coming out of the exhaust, and it smells almost like it has a cracked head, but when I checked the head, it was fine.

Firstly, you have an I6 engine not a V, suggest you not make that mistake around here. Hit up the search function for "vacuum line diagram". There is also a digram on a label under the hood normally.

There is no sticker under the hood, and I have tried searching the sight, but have come up with nothing

Not to sound like a dick but try to see were they went be4 they were chewed. Go to a local auto parts store get replacement hoses spend an afternoon replacing them. Trust me you will know when you got all of them right she should purr like a kitten. The vacuum lines are kinda easy to figure out if you take the time to look at it right. It just takes time these motors take time and patience.

Here is the under hood vacuum line routing from my 1982:

Check the link in my signature to download the Emissions TSRM, there are additional diagrams there for vacuum hoses.

Here is a rough sketch of the routing for the lines on the passenger side

3mm inner dia, 7-8 mm outer dia. is the size. You may have trouble finding it at a local shop. It's available online in silicone in various colors, black being the least common. It's pretty expensive from Toyota, and you can't buy it by the foot from Toy, you have to order it by a part number, they have one that is a 2 ft section. It takes more on an '82 than on later years. There is a lot of tubing. Maybe 12' or more? If this is just a fixer, buy good vacuum hose, any color you like, probably silicone stuff.

Hope this helps.
