View Full Version : Great News!!!!!!
I blew the motor in the Lightning!!!!!!!:flamegun: It makes me so happy I could just SCREAM :confused:. I don't have the money for a motor and don't want to dig myself farther into debt on the CC's so its gonna stay that way for a little bit.
So here is the story. Put the 6lb lower on the truck (average pulley for L's) and took it to Keith at Arizona Dyno chip. They installed the lower, and put it on the dyno. Truck made 5 WOT runs. Max timing on the last run was 16.5 degrees. A/F was 11.3 on the final 2 runs and fatter on the previous 3. It was pulling timing up top of 3rd due to high IAT2 temps and figured we need to clean the intercooler. Lightnings are very notorious for pushing ALOT of oil through the PCV system and into the intercooler then burning thus clogging it. Start it back up and uh oh there is a pretty serious rod knock. Drove it home (somehow) and sits for a couple days. Today Graham took it into school and hooked it up to the machine there and confirms that it is lower end related. I will get him on here either tonight or tomorrow to go into more detail.
I can get an OEM Longblock from Ford for 3300 shipped. Gotta decide what I want to do.

so ur saying that after 5 WOT pulls, the blower started getting hott...thats WEIRD??
i thought that it was rare for the aftercooler to get clogged by oil from the pcv system???
wow, there's a computer out there that can tell u what part of the engine is blown??? where have i been for this and where is this miracle machine located? and to think of all the ppl who still think they have to do it the old fashion way and take the engine apart to find out where the problem is.... guess cracker took to pulling bunnies outta his ass like u.(frosty the snow man joke)

damn that blows (sorry had to say it) why not get a flp short block $3595 http://www.lightningforceperformance.com/lfp-bullet-proof-54l-forged-short-block-p-486.html
and use your stock heads and super charger if possible?then when you have the dough build from there?

You should understand more details. Those 5 WOT runs were made over a 3 hour period. It cut timing out up top on EVERY run, including the first when the blower was cold... Fact is the intercooler was clogged with oil, just as I had mentioned. Not rare actually fairly common if an oil separator is not used
That magic machine you need to find is a computer that tests compression along with many other things. If you were a FORD dealer or could get to a FORD dealer you would find out that there are things like that. I was trying to avoid taking it completely apart if at all possible, you know to minimize downtime.:pinkthumb:

Wow they didnt have that machine when i worked @ ford as a drive Tech from 94-03 I guess things change. I wish you the best of luck Jeff. You and Gram should rebuild it they are not hard to do

I hooked it up to the IDS which can run realtive compression tests, power balance tests, and lots of other stuff. I ran self tests on the motor with koeo and koer to pull cmdts. It only threw one which was an over boost condition. I also monitored pids to make sure everything was where it should be. Everything was normal so I decided to put an engine ear on it. The knock was the worst on the right bank. I kept listening and started canceling cylinders. I pulled #4 and the noise decreased a lot, which tell us that is the problem cylinder. Its hard to say whether it started with a rod which led to the piston slapping around creating a slight double knock or whether the wrist pin took a dump. My guess is the rod went first. We won't really know more until we pull it apart.

just make sure you bore a scope the hole first It sounds like a piston issue.
Good luck
if you need to borrow a bore a scope we have one we will lend you to verify the problem before you take it apart
It might stay together that way.
That would be why I suggested it. They are not that hard to do. unless you are implying something different

Either way it doesn't matter I am not going learn anything I don't already know. The motor has to come apart anyway whether its a piston or a rod.
the offer is on the table good luck

Just a hint
If under power, you pull a coil and the noise goes away, it's a piston, but if it just diminishes, it's bottom end.
Well that was not my intention. As i hope personal stabbs were not yours
Im just saying the motor has to come all the way apart regardless of whether it is a piston or a rod. The truck isn't going anywhere but in the garage for a while. Will probably start tearing into it this weekend.

It's better to pull the injector instead. If you pull the cop It will keep dumping fuel...no bueno

That is bad, Im sorry for your experience. That is why I would not run fourteen p.s.i. on a stock Eaton, especially with 91 octane. Why did they not take timing out on the first run then add timing on the following runs. More boost is not always better, spinning the blower faster means more heat. Save your money and buy a Whipple.
It didn't have any timing in it. The first 3 runs were made with 10 degrees total timing. That and I am pretty sure the blower is ported. Has to be a home port its just too loud to not be ported and I don't see any Steig stamps or numbers anywhere. I will find out when it comes off. Probably could use a rebuild. First things first find out how bad the motor is and decide what I am going to do about it.
For the record I am not blaming Keith or Arizona Dyno chip for any of this.

Its has more to do with the oil consumption than the dyno or tuner.

so i have to ask the question, how would the tuner not pick this out before making so many pulls? seems to me like that would be something easy to spot...
Can't really spot oil pushing through the pcv system. The truck doesn't have an oil separator on it yet so you are not going to see it. Its not Keiths fault regardless. He has hundreds if not thousands of cars on the road and is a VERY well respected tuner. Sometimes shit just happens.
AZSonicSnake
03-05-08, 11:25 PM
was not questioning his abilities, asking an honest question. though i would have not chose him to tune my supercharger mod motor, i know he has tuned a few. just seems to me that would have been something that coulda been picked up in either the a/f or knowledge of the motor and what its known to do.

I dont think that the A/F ratio will tell you that your a quart and a half low on oil. It would be on the owner to make sure his or her vehicle is in good working condition prior to the dyno session.

and the dyno tuner, you should always make sure your truck or car is ready for the dyno before you take it in

wouldn't what be up to you (the vehicle owner)? the tuner shouldn't have to check your oil level,make sure you put enough fuel to make a few pulls and so on.hes there to make safe horsepower.

Well said
True. Like I said it was definitely not Keith's fault. I didn't check the oil level, it had only been about 1000 miles since I changed it. Doesn't matter stuff is in the works right now. The truck shouldn't be down too long.

Just a little of this and a little of that. Still have some talking to do with a couple people to see what all it will cost me but when it re-emerges it should be stronger and faster than ever.

Not to piss in anyones cornflakes, but if I take the car for a dyno tune I would expect whoever is working on it checks the car over to make sure its safe. If that includes pulling the dip stick then so be it. Not saying it was the tuners fault but I put my trust in the tuner so I dont have to build a motor.

very well said my friend. very well said.
Well after of being down for the count with a rod knock and never making it off the dyno (since March 1st) I got my truck back. I bought a used shortblock from ecoastkid http://www.svtperformance.com/forums/images/smilies/beerchug.gif and had Duffee Motorsports here in Phoenix install it after getting the motor most of the way out myself. Just wanted to make sure that it was done right the first time.
MY GOD the difference. It needs a tune and runs fat as hell up top but I just can't get enough. I haven't gotten on it at all but it is quieter than before and just rides sooooo much better than my Cobra (which is for sale). Gas be d@$%& for a week or so this will be my DD and the motorcycle will just sit.
Its good to be backhttp://www.svtperformance.com/forums/images/smilies/rockon.gif

Good to hear you've got it back on the road again Jeff!
Tune on Saturday. Lets hope this one holds together.
Took the old shortblock apart yesterday. Rod bearings on #4 and #8 were spun inside the rod. Scarred up the rod badly, the crank was a littel scarred but looks still usable. All other bearings were clean and full of oil. Block looked amazing, could still see all the crosshatching.
I will get pictures when I can borrow a digital camera

06-25-08, 05:23 PM
cool!
make sure to post up numbers and a video if possible.
and HP predictions?
Well someone will have a video camera and I will post numbers. I am guessing low 400's just because of the heat. I am hoping for low 90's when its on there but HIGHLY doubt that is gonna happen
hey jeff what time is your dyno time on sat... i would love to see the truck run if you wanna stop by and pick me up i mean its kinda on the way... ha ha.... glad to see the truck back its gonna be a beast on the streets....:bitchslap: bitch slap people with a truck...
