Hi All,
I'm looking into the purchase of a '73 2.0L and have the car at a local specialist shop for a PPI. The car has a recent engine rebuild with about 500 miles since. It runs well with the only exceptions that it surges and falls a bit at idle (I wasn't too concerned about that), but the compression test readings that were just relayed back to me are a concern. The compression readings are 110, 110, 110 and 120psi. Would these numbers be in the normal range for a fresh engine? They seem low to me. I'm waiting for a call from the mechanic with the particulars including confirming how the test was done (hot engine, thottle wide open, plugs out...etc?). Assuming the test was done correctly, would these values point to a problem? Is it possible that the engine is not fully broken in and the readings would be expected to rise? Thanks for your help! |

Welcome!
Not too many of us have Alfas here but there are some (I have a handful of 105s). 914 is a totally different drive, very complementary driving experience. 914s are a bit less fidly than the 105 or early cars. Lots of SoCal 914 people here and we do events and tech days and drives all the time. That compression is low - I’d want to know why before buying it unless priced in. |
