I'm moving to Hawaii in July and will be taking my '73 (thank you CAMP) with me. The PO kept meticulous date/mileage records (including when the car was washed) so I know that the engine in there now is a '74 2.0L with about 90k miles on it.
I've been driving VW bugs for a while and those engines seem to last around 60-100k before they need a rebuild, and while this engine still needs a tune up (Saturday!), it doesn't appear to have any issues and sounds/runs great. The maintenance of the engine seems to have been superb prior to my owning it... What I'm wondering is if my lifetime expectations of 1500-1600 VW engines apply to the 1700-2000 engines in the 914s. People generally say the 6-cyl engines last for a long time - I've heard of them running great up into the 200k range - but I don't know enough about the 914 engines to know if I should be worried that the car will bomb out in 10k and if I should build up the 1.7 into something more fun (2.2 etc.) while I have a garage and swap it before I go, or if the 2.0L statistically got another 50k in it and I should deal with things as they come up out in the islands (I have a relative with a shop on Oahu). How long do yours generally last? |

You might want to check the head temps, too. Read the earlier threads on here; oil temps and head temps have almost nothing to do with each other, and either one can indicate a problem...
"Conventional wisdom" is that 2.0s can go for "about" 120K miles. Though Brian Kumamoto got a quarter-million miles out of his original 2.0 motor before he had FAT rebuild it. I know of several 1.7s that ran for well over 150K miles. A former co-worker had one that went to 270K, and then popped the head off a valve and completely detonated the motor. "It was really hurting for the last 50K miles before that; it probably only made about 40 or 50 HP. But it sure was fun to flog!" The early Sixes are somewhat high-strung and don't seem to last as well as some of them do. Most of the original 2.7s don't seem to last 75K miles, particularly not the 75+ CA-spec ones with the uber-retarded thermal reactor exhaust setup. (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif) It's the 3.0 liter motors that have the real reputation for durability. They're pretty easily quarter-million mile motors, unless they are abused or not maintained or they break a head stud. --DD |
