Well, here we go..
I picked up an 89 SC last weekend and it's not quite right (much like myself).
The drive home was really fun, all types of smoke followed me, it was so bad at one point that a School Bus had to stop till it cleared..
Turns out the dipstick tube had come dislodged and oil was spewing all over the place.
The other issues are a heavy misfire at idle and under load, no cel, my firing order seems to have changed and she is running pig rich.
Firing order first. My searches say it should be as follows.
1-2-3
4-6-5
The only way I can get it to run is.
1-2-3
5-6-4
And it misses like crazy under load, idles like a Pro Stock and the exhaust is so rich you can't stand behind the car. Oddly in neutral it'll rev like mad but it will shroud you in a fog of fuel.
I've pulled the Cam sensor plug with no change. Ive pulled the spout with a slight idle change.
I had the DIS tested at 3 different Parts stores, two stores passed it and one failed it which is odd.
A compression test, plugs and wires will be a project for this coming weekend.
What's bugging me is the firing order.
(The car does have a few mods that I didn't know about until I dug in. I've found aftermarket exhaust with high flow cats and DynoMax turbo mufflers, overdrive pulleys, a BBK/Eddy 70mm throttle body and the MAF body looks to be aftermarket as well. I haven't checked the ECM yet.)
Yes I did buy this a little hastily. Here in the Midwest it's a bit rare to find these with their sheet metal intact at a reasonable price.
I'll stop rambling now.
EDIT: There is quite a bit of "blow by" on the mill. At idle you can see a quick chug from the dipstick tube. Im starting to think Detonation has taken its toll.
