Thanks. I had thought that from circa 90-93, the "i" was offerred with either the 2.0L or 2.1L, either as a buyer's optional decision, or a non-optional mandated/geographic limitation. Sounds like the latter was the case The 2.1 HGs I knew about, but was disconcerted to later read - after I bought my 91 900S! - that it might be a fundamentally deeper problem with the increased bore of the 2.0 block --> 2.1, and the physical proximity of the coolant passages. I plan to do a preventative head pull in the next couple of months... No noticeable probs Return to Main Index
