Went to the track today. Horrible experience all around. Took me an hour to get through the damn gate it was so busy.
Made 1 pass, 12.2 something. Had added some timing. Was pinging a bit so I let off a little around half track.
Was not running right when I parked it. Missing a bit. Decided to call it a day before I need to call AAA. Drove home (90+ miles). At idle the engine was missing ever so slightly. Probably wouldn't even notice it if it weren't for the supercharger. Slight changes in pitch at idle.
Fearing the worst I decided to do a compression check. Results:
Drivers bank
1 - 190psi
3 - 150psi![Eek! :eek: :eek:](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f631.png)
5 - 195psi
7 - 195psi
Passenger bank
2 - 180psi
4 - 190psi
6 - 185psi
8 - 90psi![Confused :confused: :confused:](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f615.png)

Also a fair bit of oil in my intake, which is usually very clean due to the water meth injection, seen by looking through the throttle body.
I don't have a leak down tester but I was thinking about setting #3 and #8 to top dead center and putting in air pressure while listening for air in the crankcase and the cooling system. I suppose I might just need some head gaskets.
What do you guys think?
What are my options if I do end up needing a motor? Keep in mind the current engine just turned over 170,000 miles.
A 4.7 swap sounds VERY tempting but I REALLY don't have the money.
Opinions please!
