#9502 of 11722 I love the 2.2L engines by paisan Dec 28, 2003 (4:54 pm)
Mine is awsome for racin.   -mike
#9503 of 11722 Seals, gaskets, and ODB2 by ateixeira Dec 29, 2003 (8:13 am)
Mathias: first problem is a leaky O-ring, i.e. the front main seal. It's not as common on the 2.2l but it happens. It should be replace with the timing belt, at 79k miles I expect they either skipped this service or re-used the old seal, a no-no.   You really want to know if it's worth buying? Do a compression test, look for no more than 10% variation. If you have a leak it's prolly the head gaskets, in that case run, don't walk. It may have had a history of overheating.   OBD2 will sniff out (pardon the pun) any gross polluters, so yeah, it should be effective just to read that data.   -juice
#9504 of 11722 emissions by gearhead4 Dec 29, 2003 (8:20 am)
In Illinois, we have switched to the OBDII connection for the emissions test. This test is only as good the the vehicles OBDII computer and it's sensors. All it takes is one bad sensor to invalidate the test. The reason the states are going to this method of testing is because it saves them big bucks and it proves they don't really care about emissions. From the vehicle owner pespective, it saves then time and money. The O2 sensor is upstream of the catalytic converter, so you can remove the cat converter and the OBDII system won't know the differece. Replace the conveerter with a similar shaped can and even a visual inspection won't reveal the corrupted emission control system.   -Jim

But I believe that OBDII can detect missing or defective sensors.
#9506 of 11722 Cat Conv missing by steine13 Dec 29, 2003 (10:22 am)
or malfunctioning WILL be picked up by the system.   There are at least 2 O2 sensors on these cars, one before and one after the catalyst. The second one monitors the catalyst's function.   -M

IIRC some Subies have 3 sensors.   -juice
#9508 of 11722 juice by steine13 Dec 29, 2003 (11:21 am)
That's what I meant by "at least 2".   Many (all?) modern engines have the first O2 sensor in the exhaust manifold. That means two sensors for V and boxer engines. Anyone know how many sensors there are in Vokswagen's W-12 engine ?   -m
#9509 of 11722 by ateixeira Dec 29, 2003 (11:23 am)
I wasn't disagreeing, just being more specific. I'd say I'm thinking of the WRX but I'm not sure.   W12 is a mess. Way too complex for the given output.   -juice
#9510 of 11722 Funny thing by paisan Dec 30, 2003 (2:33 am)
My '96 L w/o the cat and the O2 sensors in place doesn't even throw a CEL! I have to throw the OBDII scanner on it one of these days and see what it says.   -mike
#9511 of 11722 by ateixeira Dec 30, 2003 (7:26 am)
That might just be OBD Level I, not II. I could be wrong.   -juice
