bad tune help or injector ? im just trying to think, im about to take motor apart but i was wondering what the possiability of a bad tune running to rich. how can i tell if it was way to rich or ir a injector is dumpping raw fuel and destroyed my bearings? im using ford svo30lbs just curious i dont want the same thing to happen with a new shortblock. even though i did cam and heads i had good oil pressure and a healthy motor before it died. changed the oil and drained yhe block of coolant before i took off heads just dumbfounded.

also if i take off fuel rail and turn key on the injector should leak fuel constant if stuck right, if there fine then i can assume the tun would of been way off since i had no check engine ligt or codes.

i didt overfill it it has to be raw gas the oil is dark black and smells like gas. i changed the oil after the start up before i drove it. i had good oil pressure 40 warmed up i was crussing on the highway and boom. completely died locked up, no knocks pings or noises. just turned off and that was it. had it towed home and took of the ac filter filled with metal. i had uinder a hour on it after the head and cam change. so im tending to think a ford svo injector stuck or the tune was overkill thats what im trying to determine before i rip the motor back out again.

Verdad Gallardo Did you say you DID or DIDN'T overfill it? (typo on your behalf)
Too much gas in the cylinders will wash down the cylinder walls, removing the oil, and cause scoring of the cylinder walls.
Have you taken anything apart yet? Perhaps you snapped the timing chain.
If you suspect the tune is the issue, you can investigate. If you have a laptop and some free software, download the tune from the PCM and have a tuner look at it to make sure it jives.

i did not overfill it, i have not taken anything apart yet just tried to crank the engine by starter and hand nothing moving. it defenatly bearing material on the dipstick and in filter brand new gm timming chain im gonna take apart in a few days just dumbfounded i hope the new heads are ok. i dont have software or know anyone im saving and selling stuff so i can fix the bottom end i dont want the same thing to happen on another engine
Show pictures on here of the cylinder walls.
Amazing how you went from not wanting to blame the tuner to certain the tune is at fault. What am I missing?
Yeah what machine work was done to the block if any and what bearing where used? If its just a high mileage motor the bearings might have already been going bad
in one hour you would never get a half a gal of gas past the pistons and if it was running that rich it would have run like **** and you should have known better than to take it on the high way and with half a gal to much in oil pan you probaly trashed the block by cracking a piston

stock shortblock it had no problemes at all oil pressure was good and ran fine before i changed the injectors and tune. why else would the oil have so much gas in it, plugs are all fouled out exhaust ports on heads look worse than the plugs. what should i take pics of and what else should i check. it was a very strong runner maybe im comming off the wrong way. i dont want it to happen on a brand new shortblock. i was told to use same tune on new engine, im not pointing names i just cant see any other reseanon this happened exspecialy since i diidt beat on it.

i ment to say mail ordertune could of wiped out bearings sorry.it ran like crap and wouldt move out of its ownway. i have engine apart all cylinders have crosshatches in them all the main and rod bearings are pretty much trashed. all of the pistons and rods are intact nothing is broke.all im asking for is advice im not trying to makle false aqusitions.
if i had a bearing problem prior i would of had some sort of oil pressure problem fluction in the guage or low oil pressure. i had good oil pressure with no problemes no knocks taps or pings.

most mail order tunes come with a 1 year retune maybe send it back in and see if there is anything fucked in the tune every one ***** up some time and if it is the case of a bad tune you still cant put the blame of your engine on them because as soon as you started it you should have known to turn it off and fix the problem, no disrespect just telling it like it is as far as it not happening again the only way fuel gets in your engine is your injectors and if them are fine than you tune would most likely be to blame but man that thing must of ran like ****!!!!!!!!!!!
