UPDATE #2: Installed new fuel pump. Seems to be holding pressure at around 30psi or so while at idle and pressure rises to maybe 35 or 36psi when advancing throttle (in park). I have no way of checking it while driving. After shutdown with gauge still connected it held around 29-30 for maybe...

Thank you.

UPDATE: I finally got around to installing a Bosch fuel pump and will be using the existing assembly as its not rusted. The only thing I found is that there is an orange rubber piece at the tip of the return line (on the assembly) that is torn. Does anyone know what the function of this orange...

Wanted to update on this issue. Ran the vehicle again a couple times and the smoke seems to be going away. I suppose there was way more residue in the system from that stuck open injector than i thought. Im calling this a fix for now unless something comes up. Thanks for all the input everyone.

Ill take another picture tomorrow. I think it has a hint of blue in it but hard to tell. First time for me ever dealing with this smoke issue.

Well injectors are FINE. Ran it again and it smoked like crazy again after it got warm. I drained the oil after the first set of injectors i put in because of fuel being dumped into #6 cylinder. I put in 5 quarts and it was a little high. Didnt notice at first and ran it. Still smoked so so...

Good idea thanks. Do short 5 minute runs then shut it off and let it cool down.

First thing I did. Also dropped the pan to look for shavings and got lucky. Which is also why I turned it off the second time. I really need a scan tool to see if its misfiring during next run test. Because it could be residual left over and not necessarily misfiring so if I see its misfiring...

I noticed the driver side exhaust manifold collector part where its bolted to the exhaust tube is soaked and stained with something liquid. Either coolant of fuel. Im guessing fuel. The intake port next to the fuel injector on #6 was completely full of fuel when i removed the intake after i saw...

Great idea thanks I have a couple in the garage already.

I just removed the fuel rail with injectors attached and powered up the pump, getting about 30psi and not a single injector is leaking. It gets cold here but like 55F when I ran it yesterday. It smokes in the morning in the winter of course, but this was definitely thicker than Ive seen before.

Sounds like a good idea. The passenger side injectors are near impossible to get to with the upper intake on. And the connectors are a real pain to remove because they have clips on both sides. Not squeeze push ins. Ford really screwed us on the design of this engine I tell ya.

Ok thanks JC. Yes spark plugs smelled like fuel. Im not losing coolant whatsoever. And if there is a coolant leak from head gasket it will not suck up coolant from the reservoir. So when I checked the coolant level by taking the cap off, the coolant was still at the top. The way it was smoking...

All the 6 old injectors i pulled had exact same numbers on them. Mine is a '98 SOHC. It has a return line as theres two lines down where the filter is which i just changed last night. And I have the damper/regulator on the passenger side fuel rail towards the front. IT was not leaking when i...

Ok so the next set i put in i checked before installing and none of them were stuck open. I triple checked to make sure. All ohmed out evenly. I doubt they are bad. Still smoking white smoke. Not the white smoke you get when its cold either. Thicker than that. I ran it for a few minutes and it...

Right. Having the injectors spray above the valves helps a bunch. Maybe why we dont hear of bad valves much in these motors. Especially when using additives. Seems the new injectors already shipped out. Wish me luck LOL!

I took a peek into the intake ports with the lower intake off and mine dont look too bad. Ive maintained it well. Often using Techron in the gas. Theres of course a little carbon on them but not anything to make me concerned. I was wondering if since i have the intake off I could somehow get in...

atlantauto. They had no issues returning product but I noticed after i removed them the small black ring that sits just above the upper oring was cracked. Hard to explain but i didnt notice it when installing. They should not have sold them in that condition. Ill just get my money back and try...

Welp strike 1. LOL The ebay injectors were a dud. Engine stumbled like crazy on first start then thick white smoke started coming out of exhaust. Like THICK. Im like uh oh the head gasket?? But HOW? There was never any signs of leaking head gasket before the repair. Coolant level was completely...

Well that is definitely my concern. Ill update soon when the injectors arrive.

Yeah for the cost and the amount of work it takes to get to them it is worth it. I can bench test the remanned ones to make sure they at least dont leak but will only know if they spray right until i fire it up. I found a seller that has some bosch ones for like 60. I know there are fakes out...

Ok cool if you have the time then Id sure like to figure this out. I noticed the tan colored one seems too large (I.D.). I cant find any posts on whether the two are supposed to be different sizes or not. The old ones look the same size to me.

I know this is old but i just bought the same set and am in the middle of this repair. But did you ever figure out which ones go where? the sizes are so close i cant tell.

Well I finally got them all out and hooked them up to a 9v to clean them out. One of them is definitely leaking. So I have to find a replacement. Could be the fuel pump still as well but at least i know i have a leaky injector. Noticed loss of mpg as well and vibrating idle. Im wondering if I...

Yea Ive changed the fuel pump already maybe 6 years ago. I dont put a ton of miles on it so i want to say its only been maybe 30k miles since. Not too bad of a job if you take your time and have the right tools. FPR holds vacuum with a gauge so im confident that is okay. Whats left is the...
