I would get new. Your local auto stores don't sell aftermarket coils?
L20b power loss/valve problems?

Unless I read it wrong, the Accel, yellow coil, is for a 73? and the used one also on Ebay is for a 79, so what year is your car?

thanks lockleaf i found it.
the local guys do, they sold me an electronic ignition one, and none of the other ones they carry has specs on them, just like the one above^^^
it's a 75 but shouldn't matter as long as it's the right ohms

alright so i cant find the right coil localy,
found this on ebay, says its at 1.4ohms but 12v
also found this, what one should i get?
Already told you this....
EI coils are .8 to 1.0
Points coils are 1.1 to 1.43
1.4 ohms is fine when used with a ballast resistor.
This is not going to fix your engine problems. 8 pages and it's the rings and/or valve seals burning the oil and poor compression.

sorry mike i forgot the resistor brought down the voltage.
no i didn't test the coil beforehand, i just thought newer was better and tossed it like a goof
and i know its the rings because of the new valve seals
one last question and i'll put this thread to rest.
how is oil getting past the rings more on some cylinders if the compression is even all across?

Compression is held in by all the rings but mostly the top two. The bottom oil ring works like a squeegee and wipes the oil downward off the cylinders leaving an extremely thin coat. Very possible to have poor oil control but ok compression. Another is more oil getting on the rear cylinder walls than the others. This could be from the rod and main bearing having more clearance than the others.

disconnect the brake booster form the manifold and see if different.

thanks mike that's great to know.
yeah i was being a noob idiot racerx
it was a screw in type, hot, and throttle wide open.
also did a leakdown and it was about 15% loss on all cyl

Mike, in his case, will a leak down test be better?
Well he said the compression was even across all cylinders so a leak down won't point to anything much. If one were lower it might point to one of the valves leaking, a gasket or the rings.
15% isn't bad. 25% to 30% is getting pretty bad.
