We put a new head,rv cam, headgasket and all new timing componets in the 4 runner. It has an rv cam from enginebuilder. I am sure the cam and crank are lined up. But anyhting is possible, I read the shop manual and it says 12 degrees before top dead center and it still overheats but runs ok. I know a few vacuum lines are wrong, what looks like idle air control valve or something is not plugged in anymore because we can't find the right lines for it.

I set the cam and crank spun it around and they are still lined up. Then I jump the plug to stop computer from advancing, and set it to 5 deg before tbc runs like crap, fsm says 12 degrees still overheats and don't feel like it should. What am I doing wrong. When at 20 degrees before tbc it runs ok, but high idle, but it don't seem right. I have played with the distributer gear to make sure it's pointing at number one. Pulled it out spin it both directions to be sure its can't be a tooth off,

I don't know what else to do. Where exactly is the timing supposed to be? Engine builder says 5 befoer tbc, fsm says 12, you would think it should be 0.

If anyone has a diagrahm for the vaccum lines it would be much appreciated.

There is just to much left to guess, shop manual differs from fsm, and differs from what others are saying.

check under your hood on the left side. The correct timing should be indicated on a sticker.

I think we may have the timing worked out, he had me jumping wrong thing alltogether. LOL not a yellow plug, it's a black box.

The vacuum lines are still a problem.

Have a light blue plug, that is a mystery.

This website rocks! So much usefull information here, helping keep the old yota running!

I mean only one vacuum line going to the part circled in red. I do not have any blue connectors and I am hoping that figuring this out will make the truck run better.

I need to know what color of electrical plugs, plug into the the 2 blue circled parts. They both are blue plastic on the parts, but I don't have any blue plugs in the wiring harness. I think the green plugs from the wiring harnes go to the 2 blue parts..?

Green plug for the blue circle on top...
