I just got a quote from a local junkyard and they want 100 bucks for a set of efi exhaust manifolds. is that a good price? i needd to get rid of that cheesy manifold, since im rebuilding the engine i dont want to put that thing back on.
Oh, and i was wondering if all of the emmisions equiptment will still work? like the egr and all the piping going to the carb from the exhaust manifold? btw, the truck is a 85 f150 with the 4 speed and 1 bbl.

 

ive got as set ill sell for $75 with the downpipe but youl have to pick them up

 

good deal, but im in tree-hugga-fornia.

 

Similar set up here....e 150 though. My smog guy told me he'd probably be able to pass it because I'd have Ford parts showing.

As for the EGR, oxygen sensor etc, you have to hook all that stuff up again, and you may have to do a little fixing. Also, you probably need to make up a carb heat tube too, as the stocker bolts to the intake for purposes of heating up the intake.

What city? I'm in pasadena and am looking to do the same thing eventually.

 

up in the east bay, near san francisco.

 

Im in east bay too. know a good muffler shop?...Im contemplating the whole header-tailpipe exhaust on my 96 150. gotta price install/parts out before I decide...

 

well, i do all the work my self (im a mechanic at my dads place). but i know of one guy that ill always trust, he is in vallejo, off of sonoma blvd. if your going towards 37 turn right on california and he is the first building on the left. his name is ed and his business is called rpm.

 

Do you guys do smog? I have smog due in November and a P0420(if memory serves me right) insufficient catalyst bank 1. I usually try to do minor repairs myself(plumber by trade) but I am swamped right now. I also have a noise from the front that I need checked out. You interested. I am in San Pablo, would like to start diagnosis soon.

 

hmm, if you have insufficent catalyst efficiency, the computer is basically telling you that the catalyst will need to be replaced. the problem is that you have obd2 you technically can not put on a "universal" cat. you have to buy a oem or california obd2 compliant cat, i would personally try to find a good universal three way catalyst(illegal, but cheap) or get a oem replacement one(very expensive 500 plus dollars).
our shop does not have a smog machine(got rid of that hunk of ****, and got the BAR and the EPA out of our hair). plus, sorry to say, we are actually a foreign car only shop. we really only work on american cars if it is a previous customer of ours. the noise in the front would probably be a bad water pump or worn timing gears, you really have to diagnose that and not throw parts on.

 

When you use the EFI manifolds you have to be a little creative to hook up the EGR and thermactor air. Because the thermactor air goes thru the carb spacer into the heat riser. When you change to efi you loose the heat riser.
I solved this on my 84 f150 I6 carbed by using some plumbing fittings at the egr fitting on the efi manifold. first i used a short 3/4 pipe nipple to go into the manifold then a 90 degree elbow facing toward the passenger side fender. then another nipple, a 3/4 tee and then a street elbow. I ran a 3/4" copper tube with compression fittings (tube to pipe) from the bull of the tee to the carb spacer. This was a really good fit just a 90 degree bend about a 10 inch radius.
I purchased about 2 feet of tubing, Packed it tight with sand, and bent it over a log to get the right bend.
I disconnected the check valve for the thermactor air from the carb spacer and connected it to the street elbow. I moved the thermactor air valve to the outboard stud of the EGR valve. everything works fine.

 

Thanks for the info Yozsi, Does the previously mentioned shop in Vallejo do smog?

 

nope thats an exhaust shop, but if your in san pablo, why not smog your truck there?
