Hellloooo USMB. First off, thanks for all the advice on here. I've been lurking for awhile, probably should have posted something earlier but anyway... like before I bought this flesh-colored wagon.
1987 GL wagon, carbed, Hi Lo tranny and 125,480 miles and lots of...let's call it character so I don't start swearing lol.
First mistake-- didn't drive it much, towed it home.
Replaced (new parts)
water pump (old one dead)
timing belts
plugs (NGK R)
Wires
Dist Rotor
Battery
Has 1/4 or so new gas with a bit of sea foam
Used Weber DGAV 32/36 Carb, trans-dapt mounting plate, 130/130 jets. No choke. Doesn't have air filter on it meow.
I've also ripped out the interior and cleaned out the critters' collection). Sheesh that was a PITA.
It seems that either engine mounts were sheared or the bolts fell off?? One of them doesn't line up. There's a bit of crumple around the hood zone, and no grill.
I did some compression tests, and they are loooow. ($25 Harbor Freight tool) I tried to give each cyl 10 cranks, and did each three times. Removed all plugs. Didn't do wet test, from what I've read (source:internet) boxxer engine doesn't give best results for that? I can probably figure it out if y'all think I ought to tho.
3-70, 60, 75 psi 4- 70, 80, 80 psi
1- 80, 60, 70 psi 2- 70, 70, 80 psi
This was warm. (I also did the same test cold (like at 40 degrees) and they were all 100-110 psi what gives?? I did procedure same same, maybe there was moisture in there, it had been sitting for awhile?) Also, if I keep cranking, it will keep going 100+, but doesn't jump a whole lot the first crank, 10-20psi.
If I let it idle, it will eventually stall out with fouled plugs after 15-20 minutes.
With clean plugs, when I run it at 3500 or so rpm for a few minutes (in neutral, it ain't regstrd yet), the plugs look like this--(left to right 1,2,3,4 cylinder)
Odd, no? The #2 looks healthy, but the others are blackened. I guess "fluffy" describes it. If it won't start, it has been bc plugs are fouled, and #3 has been wet fouled.
This is what I think, but I the stump has been chumped, and I would like your input.
1. The carb needs adjusting. There may be a small vac leak. The idle mixture screw doesn't seem to make much difference, although I think I can hear a sucking sound when I screw it all the way in (idle screw in = less gas for idle?)
2. The engine needs a rebuild, and the plugs will continue to foul until that is done. Headgaskets came to mind? but the exhaust doesn't smell sweet by any means. It blows out a bit of white exhaust I guess. I have had to fill the coolant, but I figured that was just the cooling system filling in? Something to keep an eye on anyhow.

What do you think? Is there any other info I can provide? All input is welcome! I appreciate all your knowledge and have learned a ton lurking.
Thanks

I haven't checked for bubbles in the cooling system, I will do that. Haven't done an oil change yet, but looks ok. Not a milkshake. How much marvel in the pistons do you think? A little dab'll do ya? I'll try that. Or seafoam if you think that's a better idea. ATF for oil sounds wild. I suppose that would be last resort. I'm going to f with the carb tomorrow...unless I go skiing that is, it's cold again so I might not want twerk on the car so much. I just dialed in the float level, it's in spec. The idle mixture screw didn't do much, but I'm pretty sure I heard more hissing as I screwed it in = vac leaks somewhere. Will clean PCV also, I'm pretty sure it needs it. Looks like I can get fuel/air mixture gauges for $30 (up to $300!). I'll keep that in mind. Thanks, I've got some direction now, much obliged. Will report back with deets.
