Yeh thats the one thing I miss about my Cadillac... full access to every single code right through my instrument panel. Well, do you have an Autozone in your town? They have a code reader and will generally do it for free, as will O'riley's if they have one.

 

Yea tell me about it, I've owned nothing but Hondas and Acuras, and the ECU has a LED built in that flashes trouble codes. BUT gota say, now that I got me a V8 probably never go back to a Japanese car again. I'm not positive if we have either shops in town, I reside in BC, canada. Will have to do a search. Thanks again man, appreciate it.

 

No problem, and thats funny the whole flashing led thing. My Cadi just let me pick which types of codes I wanted to see then it would tell me all those codes directly through the cluster. That car talked (text) to me all the time though... If it dropped below 31 degrees it would tell me that there is a possibility of frozen roads... (really? frozen roads in Michigan in mid winter... no... . . . . . really?) Anyway, yeh lol. Surely you have some sort of parts store somewhere in your area that will have a scanner... I mean, they gotta.

 

So I just picked up an '88 F150 5.0 with 97k on the clock, probably 197K, anyway was gonna do the whole seafoam thing, clean it out some.
My question is did everyone change their oil soon after doing it?
I just changed it couple hundred miles ago so should I wait and do it right before the next oil change?
What does everyone think?

 

^ should do it within 100 to 150 miles after seafoam...b4 oil change let it idle for 5 mins or so to loosen stuff up. dont brive it all day then let it sit for a few.. too hot.

 

im doint it this weekend then doing tune up oil change sunday...

 

If your oil has been changed regularly, you may not have much sludge at all. We were working on my friends 95 with 4.9 recently and it has 250000 miles on it. It has had regular old Pennzoil all its life. It was pretty clean in there and did not look bad at all.

 

I have run Seafoam in the gas tank. I also use Techron.

I will absolutely not run it or anything else besides oil in the crank case. What I do once a year is change the oil and drive it for about 100-200 miles and then change it again. Thats my engine flush.

I have not used it in the booster hose to the intake. I have removed the intake and cleaned it out before though. I would much rather do that.

 

Why do you run 93 octane? There is absolutely no need to run supreme in our trucks. I usualy run plus or mid-grade 89 in mine.

 

I put 16oz of seafoam into the booster line a day or two ago. I didn't get much smoke putting it in. I headed off to lunch and got tied up, so it sat almost an hour I guess before starting. Some smoke, but still not like the videos. I put a little cheap injection cleaner in the tank along with a couple oz of Lucas. I ran a can of 5 Minute Motor Flush in the crankcase, then changed the oil.

Then it was into the garage for some TLC. My throttle body was filthy, so it got shot with carb cleaner. My idle was low, so I bent the tab a little to increase it. Timing was off just a bit, so I got it spot on. Then on to the leaky exhaust. One side tightened fine, snapped a bolt on the other.

This is where it gets good. I drove home with a slightly higher idle, MUCH better throttle response, smoother running engine with a louder than usual exhaust leak. Spent over two hours at the muffler shop getting the broken stud out and getting a completely new exhaust from the manifolds back. Looks good, sounds good. I start heading home and I hear a faint knock under load from the passenger side. I'm assuming that the it was there the whole time and the exhaust leak just covered it up, but I have to wonder...was it the SEAFOAM??????????

 

uuuummm u aint susposed to put a whole can into the booster line.... only a half at most.. susposed to do 1/3rd in booster 1/3rd in crankcase 1/3rd in gas tank...i think ya put too much...

 

Seafoam, in a word, no. Not only no, but hell no. I have a 1997 F-250HD with 336k on it, motor is now junk due to oil pump failure. What caused the oil pump failure you ask? Seafoam. You see, all of that harmlessly floating crap that was suspended before the "engine cleaning" broke loose and went straight ot the bottom, getting sucked up in the screen as it was all teeny tiny and proceeded to re deposoit in the pickup tube for the oil pump. Guess what a clogged tube causes? Oil pump failure. Tore into the bottom end to have a look, after throwing a rod due to lack of oiling, and what do I find, clogged tube, scored bearings, and a motor that is now junk. Might have had to do with the cracking due to hot spots if the oil wasn't making it up to the rockers.

 

Sounds to me like your engine was dirty inside and you didnt take care of it. Regular oil changes prevent sludge and junk from building up in the first place.

 

Hmmmm. I thought an oil change was recommended after doing the seafoam treatment, especially on engines with high mileage that may not have been maintained as well as they should have been.

 

ive never had any problems...
