    98 5.7 rough idle and stalls

    I took the rocker arms off #6 and hooked air up to the spark plug port, air went right out the exhaust pipe. So I plan to take the head off next weekend starting Fri after work. I spent an hour or so working the valve with ATF up and down and around, at first it was stuck, now it's 90% free...

    Great info! I'm doing the compressed air in the sparkplug port a little later.

    so an update. I just found a piece of small spring under valve cover, turns out its from the valve stem seal on #6. still have 0 compression. I'm about to change the seal on exhaust and intake on 6, because I'm still having missing codes come up and rough idle.

    took off the bank 2 valve cover, #6 push rod was bent and off the hat. took a rubber mallet to straighten and put it back in. I had to tighten around 3 turns for it to seat but still have a little play. doesn't die at stop lights anymore. about to replace the new downstream o2's with the old...

    yes if i had the tooth alignment off by around by like 20%, it would throw a cmp code not aligning with crank shaft position sensor. I believe the harmonic balancer shifts over time and you have to use the pencil in the #1 spark plug hole trick to get true TDC. This problem turns out to be bad...

    Here's what I think happened, and tell me if I'm wrong. Head gasket is blowing slowly from age, startin at cylinder 6 and moving it's break around. because bank 1 side is pretty good compression except the back 7 headed to the other side. just read the last response and I believe it makes sense...

    Just to update, that cylinder #6 that was throwing a code has 0 compression.

    98 5.7 rough idle and stalls

    I ordered all 4 O2 sensors off amazon for $45, the OEM ones are $60+ a piece. put the old ones back on and my obd2 readings came back to life. Compression test revealed blown head gasket. = new engine. Those cheap sensors on amazon do not work for this truck. I spent a lot of time on the fuel...

    so yeah compression verdict in. #2- 109, #4- 131, #6- 0, #8- 138, #1- 145, #3- 150, #5- 140, #7- 132. does that sound like head gasket? no coolant in oil or blowing smoke of any kind.

    its not burning oil just too much gas from the computer

    98 5.7 rough idle and stalls

    so i guess my next step is to do compression test and see how far it goes...

    98 5.7 rough idle and stalls

    that is a good question, i took apart the ecm looking for broken solder or burt connection and it looked good. one thing is i fixed vacuum leak at brake booster plug with electrical tape and now i have to stand on my brakes to get it to stop!

    I haven't done a compression test. spent that money on a fuel pressure gauge. 238000 miles. so every once in a while I would get a misfire cyl 6 code when I got on the pedal. then it would go away. then one day i turned the corner getting on the freeway normal like and boom, something flipped...

    I just redid the timing moving the distributor one tooth at a time and checking. it's closer now at +13. It was running super rich thats why i changed the o2 sensors they were black! all the plugs had oil on them except cyl 6 when this all started. one thing that is concerning, the fuel...

    98 5.7 rough idle and stalls

    hoping I can get some help. obd tool says OL fault, no stft or ltft. getting PO300 misfire codes, o2 sensor b1s1 and b1s2 shows no activity. I've changed everything emission related including o2's. new fuel pump. pressure at 55. new distributor. cam retard at -30. can't get it to change with...
