Nice!

 

In Canada here and I've been hot and cold about buying an '89 C4 with 150k miles. Top end has been redone and she runs good with no smoke. Price seems to be fair as well. Someone just recently told me a PCA member said the bottom end is good for 400,000 km if maintained.

 

Mine has 207k on the engine. It had oil leaks repaired at 104K, but it runs great and is strong. Oil pressure is great, even when the oil is very hot.

I'm building up my spare core to my 4.1, and I'll leave this one as is😬

 

The reason for rebuilds may have been influenced by some other factors e.g.
1) It's not straightforward to read the oil level, therefore some owners may not have bothered. Oil surges in the middle of it's life may have shortened the engine's life. A car at about 12-15 years old is not particularly loved...
2) I was paranoid when I removed and refurbed the oil-tank. The potential for dirt to fall in the gaping lower hoses and thermostat is enormous. If a garage had done it, would they have been as meticulous in getting everything above in the wheel-well clean? Any dirt falling in would have slowly done damage to all kinds of bearing surfaces over time.
