i am using a rear sump oil pan on my 5.7 but the dipstick on the side will not work because the plate between the pan and the block dosent have a hole for the side dipstick since i have already assembled the engine is there a way to cut that hole without removing the pan?

i totally agree i purchased a diablo sport scanner from chris when i bought the hotwire system but im not really very good with it im looking for a laptop based program to buy that may be easier to use

you are absolutely correct i mistakenly said i have a mass airflow sensor when i actually have a map sensor and i did email chris about the problems and he suggested i disconnect the battery to reset the computer and see if it helps the problem. also the white smoke disappeared when it warmed up...

can anyone suggest a laptop scan program for use on a genIII hemi swap. im looking for something that i can use to read codes and monitor systems without all the other junk that comes with the universal programs.

one thing i forgot to mention is when it was idling rough and backfireing i notice both exhausts were puffing out white smoke i had never seen that before

yes they were only in there for about one month and maybe six starts

they are both a bronze or gold color very little difference in color from the new ones i put in

well i have listened around all the manifold and vacuum and the injectors and dont hear any odd noises and i checked all the fuses and they are ok what confuses me is when this happens if i remove and replace both o2 sensors the backfire stops and the engine idles smoothly but it has happened...

i have a car stethoscope i will do that and see if i hear any leaks

if im right there are only two vacuum ports on the 5.7 one in the rear of the manifold and one in the top front any others that i should look for?

hmmm that is an interesting idea possibly the vacuum leak just occurred and thats why the problem just popped up i will have to run thru all the vacuum hoses to see if one is cracked or come off but let me ask you this if there was a vacuum leak and i changed the sensors and the problem no...

well you got me there im not sure about heaters in the o2's i did not know there were heaters for those the harness is from hotwire so i assume they may be there somewhere i checked fuses and do see any bad ones in the fuse block i think the code was po139 bank one sensor 2 or something like...

no the plugs look good i guess i should have provided some history when i originally built the car two years ago the motor was a new crate motor and until just a couple months ago the engine ran great no issues then this rough idle thing started and when i ran a scan on the car it showed the o2...

yes i do have a mass airflow sensor and the o2 sensors are located just in the front end of the header collectors

i have a fuel pressure gauge at the fuel rail and it is reading between 57 and 58psi when engine is running and i have read that that is the proper pressure for a hemi

no i am not running cats i am thinking about changing to an aeromotive adjustable fuel pressure gauge and see what i can do with that i dont know how to lean it out i have never done any tuning on the ecm it was reflashed by chris at hotwire when i did the initial install

brian6pac i thought that might be the issue but i dont find any fuel in the vacuum hose i am using the corvette regulator and it is not adjustable i changed both o2 sensors and it seemed to solve the problem but it has happened once before so i am thinking you are correct do yo have any idea...

my 5.7 hemi has been sitting for a month and when i started it it started fine but after a few min of idling it began to idle rough and i could hear a few small pops from the exhaust. i recently replaced the o2 sensors and it ran fine when i covered it up could it be the same issue should i...

Riddler i have been looking at the two o2 sensors i took out of the car and the one that was failing has just a small amount of blackening in one area around one of the inlet holes the other one is about the same. if i understand afr correctly if the motor was running too rich the blackening...

i think you are correct AJ but im not familiar with how to reset the ecu to lean it up ive never fooled with that since i had it reflashed

THANK YOU

heres a couple of todays photos of the hemi install

i would love to find a handheld ipad or something similiar and the programming to let me see what my engine is doing i;ve seen people using them on tv shows but dont know much about them . i used hotwire and chris the owner has been very helpful

AJ i have thought about that same issue im not sure what happened it was running fine and just suddenly started missing and small exhaust backfires until i got it home about five miles or so. im thinking it may be too rich but im not familiar enough with the diablo system to know how to lean it...

Riddler you are very kind i appreciate this site it has been invaluable during the construction of my car. i have been watching your progress and i hope you get it done soon it will be a monster

i have changed some stuff since these photos it has a polished 6.1 manifold polished valve covers and coil covers now

well let me see if i can upload a pic for ya

GOOD NEWS replaced the o2sensors and i came back to life thanks riddler and dart for all the help have a great day guys

no Dart it starts easily and the backfire is in the exhaust; Riddler i just replace both o2 sensors and im replacing all the plugs then i can try it and see if that solves the issue thanks for all the help

ok i have located the o2 sensors and i only have the upstream ones on each exhaust so im going to replace both
