El Presidente
So I woke up this morning to a text from the local track which inspired me to work on the Blue Flame so when the chance came along I might get to take it back to the track. With my work schedule and all the rainy weather as of late, I haven't been to the track since spring!
I needed to replace the valve cover gaskets since the last time I checked the plugs I had found most of the COPs wet with oil.
I had just recently moved the car a couple days ago and noted it needed a wash so I began with the intent of washing it prior to diving in under the hood. I started the car and was sitting in the garage waiting a few moments for it to warm up a bit before backing out when it happened. The car sputtered a bit then started making a horrible thrashing metallic sound. Startled for a moment, I tried to listen to it in an attempt to identify the sound when after a couple seconds it quit making the noise, then the car simply sputtered and then died.
Baffled, I turned off the key and proceeded to investigate. I could find nothing visibly wrong. I even looked underneath and found nothing to have been leaking. Oil & coolant levels both looked fine. The only thing left to do was to try to start it and see what happens. It didn't start right up but did finally start and went into it's normal 'high idle' mode, albeit with what seemed to be a more pronounced cam lope. When the rpms dropped it seemed to be idling very rough. I tried to give it some throttle but it refused to rev. It was almost as if it was out of gas. The other oddity I noticed was the AFR was showing way lean at idle. It usually idled right at 14.7 but was now reading high teens and jumping to over 20. :eek-large:
After less than a minute I shut it down.
After pondering a bit, I presumed the worst and began prepping for a compression test.
The results...
Passenger Side front to back:
1-100
2-97
3-100
4-100
Drivers Side front to back:
5-187
6-150
7-167
8-195
Now what? :confused-red:
Cylinders 6 & 7 have been erratic for quite some time but cylinders 1 through 4 previously tested 185 to 195 (same as the 'good' cylinders on the drivers bank). Between the noise incident and the results of the compression test, I'm thinking something went wrong with the cam timing for bank one. :mad-tilt:
I'm going to try a leak down test and see if that reveals anything further.
