Out of curiosity, how difficult is it to work on the 2.2 ecotec engine compared to the 2.2 ohv or 2200? I have had an 2.2 ohv & 2200 but never an ecotec but will be getting a cavy with the ecotec prety soon. The ohv/2200 I know pretty much inside out but the ecotec I know just a tad, there are alot more aftermarket parts for it from what I have seen which is great. Just want to know what to expect as I plan on making it my daily and main project car.
