test my knowledge-

[chucked]

no, if you apply dielectric grease to all connections and mating surfaces, you should be alright, theres millions of engines out there everyday with no seal on the distributor.

wd40, that will run the water out of the distibutor- garuntee that will work.

8*btdc is standard textbook. if you get better performance from a higher degree, you will be ok, as long as there is no backfires in the exhaust or intake.

i dont know th part number, but you can cross reference them at autozone.com. they are both exactly the same, because the rods, crank and pistons are the same in weight and length

all i did was block off the pcv crankcase breather on the valve cover, put 1 cup of transmission fluid in my oil, and lightly sanded down my Hall Effect Switch, or whatever is under the cap, it had 3 t15 screws, and 2 holding some black peice ontop for the rotor, the 3 screw deal slid off an dhad a magnet on the bottom, it looked rusty, so i lgihtly sanded it and sprayed wd40 on and let it dry, still got popcorn sound from my exhaust, but so far so good, my check engine light came on yesterday, code 32=egr or 4wal but i dont have 4wal so its egr.

i paid $120 for the dealership to replace my egr and its related parts... so i reset the computer and it went away and hasnt been back, but now it idles high at startup for a second, not a big deal its normal?

ill check my mileage after i get to like 1/2 tank, especially at $3.17 a gallon! hopefully itll drop, it rose 20 cents

good to hear you gas mileage is better. every 2.5 i has seen idles high at a startup, i think thats normal. the popcorn sound is probably a leak in your exhaust somewere, because you descibed that it runs good, so i believe its a small hole somewere in the cats or manifold.

Now it's doing nothing, probably killed his battery, but even if he charges it, I doubt it'll start. Any clue?

damp distibutor, stopped up fuel filter, weak fuel pump, dead fuel pump, coil could be bad, bet that it is. pull the coil wire off the distributor (center wire) and place a screw driver in one end and hold it close to the intake manifold while someone cranks and and watch for a spark, if no spark, bad coil. listen for the fuel pump to come on when you turn the switch on, it should run constant for about 2 seconds with the switch in the run position and engine not running. lemme know the results so i can further help

thats the hard way, just spay some wd40 inside the cap, it will not catch fire, so do not dry it, leave it moist with the oil, it will never get wet and will not affect the spark, i garuntee that

I'll try that.

Hey BTW, with disconnecting the PCV hoses, theres 2. your suggestion is to disconnect the one that goes to the air cleaner, where does the other lead to? manifold after the butterfly?

the small diameter metal line runs to the tbi below the butterfly, dont block that one, the large diameter that goes to the breather is the one i block.

few questions- i've got a 89 2.5 with 5 speed has been sitting but fired
every few months until the battery died like 4 or 5 months ago

theres old fuel in it, i know it doesn't matter how much it has cause its stil in there but theres like 1/16 of a tank in there

needs a tranny anyways so i don't want to dump money into getting it going
cause i can get a 4.3 auto tran and shaft put in and running for a day and under 350

i really love the little 2.5s mine has 354 027k just over 120k on the
rebuild

leaky gasket some where and some one didnt weld shut their custom manifold into header so now theres a 1/2 gap around 3 quarters of each tube on the manifold
(luckily it was only driven for two months after the header was put in)

what are the questions?

[gnar kill]

lol good to run the gas if the lines and shit are gummed little bit of additives
and run the gas, siphon , i think it needs fuel filter but how do i go about cleaning the lines injectors or w/e you think it should be good..?

there is no cat converter on it, its got a brand new manifold, it did it with the old manifold, which the front tube was broken off.

its got a straight pipe from the manifold to the muffler, then has a turndown right after the muffler, it was all welded up, but i had to cut it off and make it a turndown before axle so the mmuffler is bolted onto the straight pipe. havnt seen any areas of leaks where its bolted.

so far, im at 60 miles and i have 7/8ths of a tank left, before i blocked the breather and put fuel injector cleaner in, i got 56 miles till i was at 3/4 tank, so it seems like im at atleast 16-20mpg

good thread, irondukeman...I'm on my second Iron Duke (and my buddies and I rebuilt this one from the oil pan up), but it's been pretty much sitting for 2 yrs, so by the time I get it on the road I'm sure I"ll be using this thread a lot

gas after it sets for a while turns into turpintine... bad stuff, eats up any plastic or rubber, especiallt the fuel pump lines and seals. get it out of the lines and tbi fast, or throw some high octane fuel in it and burn it out

remove the fuel line input line at the tbi and the lines from the tank, and run some mean green or any strong degreaser, i personally would use that stuff called "goof off" or some kind of paint thinner to really get a good cleaning and remove the build-up. it is fine to run the gas, as long as ther is not a lot of trash or it will clog the injector or the fuel pressure regulator, or a line.

thanks, im here to help!

[2.5FearFactory]

and it's much appreciated!

Just reading the thing about leaving the gas in there for too long...my truck has been parked for just about 2 yrs though it does get fired up occassionally...I started it about a week ago and it ran like a champ. Does that mean that (so far) I'm good to go? If yes, then I'll just send my buddy some money so he can keep burning all the gas in the tank and just put a few gallons in at a time.

as long as you run it a little every now and then its fine, because you are churning the gas and running all the build-up out of the lines and filters

[2.5FearFactory]

beauty...thanks man...I'll just get my buddy to run it every now and again...I once had it standing for 9 months and it was totally fine ...fingers crossed!!!

[irondukeman]

anybody interested in a very detailed how to in replacing your valve stem seals? i just did a little 2.5 and i have a bunch if pics... its a good solution in stopping your engine from burning oil or puffing blue smoke on a start-up. takes about an hour and cost me less that 11 bucks

[kamesama980]

I did a write up on my old Cressida (DOHC I6) for that forum but I'd be interested in seeing it with this antique. I imagine it's a helluva lot easier.

[beaniebmx]

i make gaskets for a living, so if anyone needs some valve stem seals, i can sell you a full set un used in brand new shape i made

i also have a k-cork valve cover gasket and a lifter cover gasket if anyone wants those too

[irondukeman]

hook me up on some 5.7l gaskets, ill pay all the overhead- and ill be you 2.5 part hookup, i have access to cheappppp parts that you cant fond anywhere else, look at the pic i posted in the topic, look at this!- i have that same engine with the electronic ignition coils instead of distibutor and a side mount blower- its not a running engine, but with a good donor and a fresh rebuild, it could do some damage.

[beaniebmx]

ill need specifics

5.7l 350v8, year? what gaskets? what type? k-cork, n-8094 with silicone bead intakes?, steelback exhaust manifolds? neoprene rubber valve covers?

let me know what you want, we just got 8 semi trailers full of gaskets for kits, so more than likely we have what you need, but i dont think hell let me just walk out with 5000 mrgasket 5822 intakes at 88 cent unit price

let me know exactly what you want, i can ask whenever hes in, and find out what the price would be

if your wanting like 100 head gaskets, it would be something youd more than likely have to order in from us, something like water inlet wed probably have for kits. seen some 4.3l and 5.7l on the kit strip list

[ratrod dime]

I have one for you.

I have a 1986 2.5 w/ auto. 2wd ext. cab. well its got a new fuel pump, injector, plugs, wires, cap, rotor, all new filters. the tank has been dipped to clean it. and it starts hard, like a dragster when it first starts to idel. then when it smooths out it hickup once and awhile, butthe worst is when I am driving it, and I slow down to stop a a light. it stalls out on me?
I need help badly.

you need a new map sensor or check the vacuum line going to it. its the rectangle piece mounted to your breather, autozone checks them for free

[JML]

My truck would make the popcorn sound every time i let off the gas, it had a big hole in the pipe before the muffler, but the cat was still ok. I ran straight pipe for a while after the cat and the popping stopped? Then i got an exhaust done and it sounds normal.

just some backfiring. underrestricted exhaust allowed everything to get out fast enough to not burn all the fuel. all the cars I've worked on do it if you cut the exhaust off before the header. all old cars. rev it up then let of and it burbles cheerfully to itself.

[ratrod dime]

ok i had the map sensor tested at autozone, and it tested good. we checked all vacuum lines and they were all good. so I still could use some other ideas.

thank you guys.
