Ok I got myself a compression test kit. It was only $42 (Canadian
). I eyed up a coolant test kit and it was $54, I didn't buy it because my wife might kill me.
Both #4 and #8 are a B!tch to get the fitting in, but I did get them in eventually (after a few...many...choice words).
Cylinder# Pressure
1 152
2 150
3 145
4 145
5 140
6 145
7 146
8 149
I got the car warmed up and stared to take things off. I removed the front brace and cold air ducting. I then removed all 8 wires then all 8 plugs. I checked the gap on most of them. It was between 0.050 and 0.055.
I started at #1 and went to #8 (well I actually skipped #4 and came abck for it after #8)
The car had cooled down some (it took some time to get #4 and #8) but even at the end the adapter was almost too hot to hold.
I cranked it over 5 times on each cylinder.
I started thinking about the gas smell, could I just have a screwed injector? Or maybe a crack in the intake manifold?
Well I hope this is enough to generate some ideas.
