Wow, sorry to hear that. Cranking an engine without fuel will not cause this to happen. So were you driving the car, and it just killed itself or you saying while you were cranking it. I dont have any personal experience with our local shops as far as engine building goes, but i'm sure some members can chime in on that.
right as the fuel issue was resolved it started up but it spit up all that coolant and metal out the exhaust. so it ran a total of like 10 seconds before it died. i had a custom tune from amazon racing for my setup but i was going to get a dynotune anyways, just this happened. the car had 0 mechanical issues prior to going under the knife and getting a ported blower put on along with other misc mods... i guess i will be taking the motor out this week and ripping it apart to see how bad the damage is so i dont waste more money on a rebuild when tousley is running a special on longblocks..
OMG there had to be a backfire or some minor explosion when it started.
i didnt hear an explosion because of the open long tubes.... i just dont understand how this could have happened.... i thought these motors were strong
i purchased a used boost a pump with wire upgrade and wired it in to how the installation instructions on svtp explained. first i replaced my fuel filter (which was a bitch with the irs in the way) that didnt help, i replaced the frps (that didnt help) so i went back to why the pumps werent kicking on and double checked the bap and this time i actually checked for which wires went were on the relay and noticed it was wired wrong from the guy i bought it from... so i flipped the two wires that connect to the black and green one and magically that was the fix, started it up with 35% on the bap like my tuner told me to and it started right up, turned it off and noticed coolant everywhere, i thought a coolant line busted but it came out the headers so i tried starting it again and it fired up perfectly only this time when i turned it off there was all that metal and now the engine doesnt want to crank over at all.
guess i will know once i take it out and rip it apart. which i dont even think i will be doing seeing as how tousley is willing to send me a longblock for $4000 with a outstanding warranty...
i wish it was at least my fault so i can man up, move on and get a new block but i can honestly say that i dont kno wtf happened.
I would have the injectors checked before using them on your next engine in case one stuck open and caused this problem.
that was the second thing on my mind, i purchased those used as well. i will be sending them out to steggy next week, unless maybe there is something local...???
Whats up DTUB!!!!
Mr. Norms is a famous Mopar Shop now employing Tim Barth. (Tim used to own Modular Powerhouse in Georgia but has moved up here.)
Hey PRO-Z, haven't heard from you over at MM.N in awhile. Are you getting ready to surprise us with something?
took out the spark plugs on that side and found this, all of them smell like gas (no coolant visible) all other cylinders were fine except this one i think its #7. so far i can see the piston needing to be replaced and that head because of the stripped thread and all that metal missing. but i still dont know why this happened. could it really be because of an injector?
