Ok guys the other day I decided to change the water pump gasket between the housing and the block and replaced it and all was hunki dori and then next thing i noticed is that it would idle rough but as long as I gassed it thru and warmed it up it would run great. I assumed I got something inside of the sensor or something.



Anyhow after I drove it and it was warm it would start up easily and run easily, but after sitting all day or night it would take me ten minutes of unflooding it to get it to start. I drove it today to wal mart and it was fine and when i came back out to the parking lot and started it ran really rough and seemed to only run on one rotor and was shaking really badly and sounded like something was rattling inside of the motor (apex seal?). Would something go wrong while parked? Why would it run and then give up while in the parking lot, and what would have changed my car so dramatically from changing the water pump gasket?

 

ok i did the ghetto compression test in the link and i also did the atf trick and It ran and got started and everything but it still felt like it was running on one rotor. The exhaust sounded really weird compared to normal. Anyhow I decided to go ahead and try the compression check and listen for it. Anyhow I pulled the spark plug on the rear rotor and could hear pff pff pfff pff pff just fine. Then i did it to the front rotor and heard not a single pff at all. Nothing. If I had somehow blown an apex seal I would at least get some kind of pff at least on one of the rotor faces. So why would I not be getting ANY compression whatsoever on the front rotor.



Remember it ran just fine before I had parked it BUT I was having to spend 10 minutes to get it to start and run in the morning those few days after I had to take the water pump housing and all out of the car. I replaced the water temp sensor but also keep in mind that I had to remove those four oil lines to get the water pump off. Would messing that up somehow ruin compression on my motor by not allowing me to build up a seal? Any ideas. This definitely has to be related to the work I did on my car. Also keep in mind that I had to constantly plug and unplug my battery because while working on my car i screwed up some wires I had run into my ignition switch to bypass a bad wire. I got all of that fixed up and tied back but the problem could somehow be electrical maybe? ECU fried and bit the dust?

 

If you blew one apex seal, a chunk might have cracked the 2nd one, and you would hear no pff pff pff on that rotor.

 

boooooooooooom.
