90150F

K well for some reason I decided to do a tune up on the old ford. Didn't go to great. I did valve cover gaskets. intake man gasket plugs wires dist cap rotor oil and filter. All that good stuff. Well in driving it after all that I notice flames coming from the pass side exhaust man. My plug wires got melted a little and some vacume lines came undone. So I decided to change the pass side valve cover gasket to one of the rubber kinds hoping that maybe it leaked oil onto the manifold. I also changed the pass side wires. Now I am afraid to try it because by all the canisters behind the batt there is a white looking vac line that is unpluged. There are three of them running together. Two of them cut off and go to one of the canisters and then there is this white one. I looked at my buddy's truck and down by the air pump on his there is a valve looking thing that has a vac line on it. Mine doesn't have that same set up. Anyone have any idea where this vacume line goes. Any other idea's of why it cought on fire. It was shifting funny when it did it. It would shift but only when you got to a higher rpm. Please help. Will take pics of needed.

Thanks

It also blew a lot of white smoke would the intake manifold not getting sealed right cause it to do this maybe? someone told me i didn't really need to put silicone on that. I did on the bottom but not on the top. ??? It didn't smoke before I did all the tune up stuff to it???

Thanks

Valve covers leaking oil would not cause a fire unless it was really pouring onto the manifold. Make sure the gasket did not shift when you installed it.

White smoke is coolant. This is from the intake manifold gasket not sealing. You need to stop driving the truck and do it again. Water is a terrible lubricant and if you're washing your cylinders down with it.....

Use silicone sealant very sparingly - you don't want it circulating through your cooling system or clogging up any oil passages. Scrape off what you just put on - make sure you get all of it. Only use a thin film of it around the water jackets, on both sides of the gasket. Leave the gasket dry everywhere else.

Shifting problem might have to do with vacuum. I'm not familiar enough with Fords, but older GMs used a 'vacuum modulator' as input for when to shift. If you left vacuum line(s) unhooked, or have a serious vacuum leak at the intake then this would cause it to shift funny.

Can't help with the vacuum line.

Good luck.

ok check this out... on the back of the motor is there a vac line going to the tranny? Like the older Fords there is a line going to the vac modulator on the tranny that controls the shifts, if the modulator on the tranny is going bad it will allow the tranny fluid to be sucked up this tube like a straw and then be burned in the motor (white smoke) pull the hose off the modulator at the trany, if tranny fluis comes out it's bad. It's simple to replace and the tranny shift (hard-soft) can be adjusted with a screw driver inside the nipple where the line hooks up)

if this line came loose, or fits poor or you lost alot of vac somwhere else (other lines off) it'll cause shifting issues

I didn't think this year had vacuum to the tranny. It should have a kickdown cable if it's not the E4OD and it may have got knocked out of whack when removing the intake. It connects to the throttle body.

that the cable right next to the throttle cable. It seems to be fine. Got it all back together but that one vac line on the pass side and it will turn over but not fire up. This thing is a pain in the ***. any ideas?

There should be a vacuum hose diagram under the hood on the airbox. The way it was shifting that you described is a symptom of the kickdown cable being out of adjustment. It is best to readjust them anytime they are removed. As far as it not starting now, it may be from the fire damage or just from you hurrying from having to do it a second time and forgetting something. Take another look and make sure everything is hooked up.
