Nice fart.

Technically, I suppose it was a "shart"

First, you cant trust a cold compression test. It will give you false readings that are meaningless.

Second..start it up after you change the oil and filter.
Run it for a long time to heat up the motor and the exhaust...get all the oil burned out of the muffler...

Do a compression test right after you shut it off.
Take out all the plugs, open up the throttle body and fix it there.
Use a threaded hose type compression tester.
Remove the relay for the fuel pump so you dont fill up the cylinders with fuel again.
Turn over the motor for the same number of seconds per cylinder.
Post those readings...a warm compression test.

Thanks, Rich.
Been planning to get a warm compression test once I got the thing running.
Hope to have some numbers to post tomorrow.

if its close...re-torque the heads and test it again.
most of these motors need the heads re-torqued.

My car did everything you described...white smoke...oil/gas puking out of the tail pipe. If there is gas in your oil in the case, check the fuel injectors. Turns out one of mine was stuck in the open position and caused it. (IMG:style_emoticons/default/headbang.gif)

Hmmm... I did check to be sure the injectors were firing properly and they are. Not stuck open at least. Good spray pattern. Pretty sure it is from cranking it so much without firing (IMG:style_emoticons/default/idea.gif)
Thanks for the input.

Kinda read through all the posts, even the Sharting one.

If it were me, I'd do a proper warm up on the engine, drive it if you can. Those compression numbers aren't that bad at all and #4 that fell a little under 100psig might come up within spec after driving it.

(IMG:style_emoticons/default/driving.gif)

As others have said, change the oil, make sure it's as good as can be.

If it's been sitting, it's worse off then if it had been driven.

If it's been sitting, I would run some mystery oil through it, might help loosen up the rings and such. Made a huge difference in mine when I first got it. That was 15K miles ago.

Do I add the Mystery Oil to the gas or oil? I actually have some that I bought for something else and never used.

Oil,er, both. I ran it in the oil, cleans carbon out quick like. I ran it for about 200 miles then changed the oil and filter out. Always start with cheap oil on a motor thats been sitting, cause your gonna want to change it right away again. As far as putting it in the fuel, it does help injectors and clean the valves, but I guess so would injector cleaner.

Update: oil and filter changed. Mystery oil added. Started right up. Smoking like crazy (how long should I expect it to take to burn all that oil out?) (IMG:style_emoticons/default/icon8.gif)
Plugs 1,2,3 were dry oily. 4 was clean (IMG:style_emoticons/default/confused24.gif)

Here are compression numbers with motor warm:
1 = 130
2 = 135
3 = 128
4 = 105

Thanks!

Get it warm. Mystery oil works better after a warm up. It may also cause some smoke, since it's super thin. I'd say 15 minutes and you should start to see it clear up.
