Low compression in 1cyl of M30...
I'm selling my E34 at the moment, it has too many things coming up due for repair/replacement, and I need the money. Plus, I've owned it for 3 years, and feel the need to try another car. I've found an E32 that's a bit rough around the edges, but going for a good price. It has few primer patches, a rattle in the front, and needs a general tidy up, but most significantly, has low compression in 1 cylinder. The owner bought it with the intention of doing it up, but never got around to it. It's a 735iL, and has the self-leveling LAD system replaced with conventional suspension.
The car is driveable, but runs rough under 2000rpm. What can cause low compression in a cylinder? Is this easily fixable? Owner states it may have a cracked valve, but is not sure.
This is of course all dependant on the sale of my car.

Dan, your 21 year old logic amuses me!
An enigma wrapped up in a contradiction!
Then again you could just edit your post and remove this part.......and then everything would make sense!...it has too many things coming up due for repair/replacement, and I need the money...

I can get $4000 for my e34, this e32 is going for $800. I figure that I would spend $1000 on it, have a nice car, and be $2200 better off! What could go wrong!Dan, your 21 year old logic amuses me!

With an $800.00 E32....?
Okay guys start the list....
Seriously spending a grand NZ (about $800.00 AUD or $600.00 USD) won't bring an E32 back from the brink. If money is a concern then you need to get European cars out of the equation because saving money and European cars is like I said before... screwing for virginity. You say that you can't afford to keep the E34 so you're planning on buying a half clapped out E32.... ??????? Well it's a slight improvement over the Audi Quattro but still not a money saving strategy old chum.

Suspension/handling is fine, no shimmy or play. Transmission fluid is not burnt. LAD is removed.
However there is a hole in the leather on the drivers seat, and a few primer patches on the paint... Only cosmetic, and could be fixed as funds permit. Front suspension rattles a bit, probably just loose strut nut or worn bushes.
I figure the $1000 allocated for repairs would get the low compression in cyl 3 sorted out, valves adjusted, and all fluids I would change myself.

Would low compression set off the cel?

I don't know what a used M30 costs over there, but they're relatively inexpensive around here. If everything checks out okay, I wouldn't hesitate to buy it and R&R it.
But get the 4 gees for your 525, first
