What are peoples views on the above engines, as fitted to later Cav SRi 16V's e.t.c. Are they as reliable as the older Red Tops? Do they still suffer from the old porous head problem? Any issues to look out for with them?
i've got one of these, and the view from above is rather good! the thing that worries me is that it was a development engine destined for the vectra (i believe) and i'd really rather have an older model of anything 'cos it's got the r&d invested over years.
My brother first had a mk 2 Cavalier 1.6, which he replaced with a 2.0 8v, which he said was much quicker and more responsive. He has now replaced that with a 2.0 16v ecotec Cavalier, and he said that the difference is about the same again. Far more energy than the 8v, and more economical too. (And it's got 110K on it, and runs perfectly)
I've had my Cav SRI 16v Ecotec (1994 M) since August now, and I'm impressed with it. It's soooo smooth, probably due to the fact that it's fitted right accross the range of the late 2.0 Cavaliers (so it needs to be smooth because it's gonna be driven by people that only use their nice 2.0 M and N reg cavs once a week to do the shopping in etc, compared to the C20XE, which is just in the earlier sporty Cavs)
I'm aware of the problems with sensors etc, and have had a Cam sensor go wrong on mine already. That cost me £50ish from Vaux, and I paid a guy in our local F*RD Rapid Fit £19 to fit it, cos one Vaux dealer wanted £32 to fit it, and another one said "Ah well, you'll have to bring the car in, we'll run the diagnostics on it. It may not be the Cam Sensor, it could be a lot worse....blah blah blah........ The last one we did here cost £170 to fix, and we've had faults like this costing £300 plus!" So I got the guy I used to use to fix my Fords to fit it for me, and haven't had a problem with the car since. *touching loads of wood now*
They are pretty quick motors, although I've never driven a C20XE engined car, so I can't compare the two.....
Originally posted by green manalishi steve, what were the symptoms when your cam sensor went?
Basically, the car would run like a bag of crap due to the EMS(ECU) light coming on. This of course puts the car in "Limp Home" mode, and limits the revs to 4500. The light coming on was intermittent, and never came on when I was driving, only just after I had started the car up.
I could then "Reboot" the car (ie. Switch it off, and start it up again) and sometimes the light would stay off. It would then stay off for the entire journey, but would usually come on again after I started it again.
I did the ECU Fault code test, a la cavweb and found it had Code 92 stored, which is "Cam Sensor Incorrect Signal". So I then had said Sensor replaced and all has been fine since. I had this done in October if I remember correctly.
