Reasonable like expectancy of a 3.2 with 158k

[ancashion]

There's a car being sold with 158k on the clock- never refreshed or rebuilt. 158k is fantastic for any engine so kudos to the owner for taking such good care of it. That said, what would be reasonable expectations for these engines? I realize there are numerous variables involved here and I'm certainly looking for no guarantee on the engines longevity but some insight into its potential would be helpful.

Basically, how much life is reasonably left in an engine with 158k that's never had any work done to it?

I wouldn't think much but have an open mind and am willing to learn something new!

There is people here with twice that mileage but since you are not the first owner, the PPI is crucial as a good rebuild will cost at least 6K if you do it yourself...

Do spend the money on a good PPI, one with Compression Test and Leak Down.

Get recommendation for the shop as many of them don't do the Leak Down properly.

If they wont let you watch the PPI get another shop.

Certainly there are exceptions to the rule, as with anything else. What's the general rule though?

Compression and leak down are a good idea to check the condition of the pistons and the heads but give zero indication to the status of bearings, which I would assume at 158k are on the downhill side of their useable lifespan. I do agree that they are worthwhile tests though.

On a side note, I have to tell you. Your car is gorgeous!!

I think there are too many variables. The thing is a lot of the 3.2's have valve guide issues. That means a top end rebuild. A lot of them also have worn lay shaft bearings.

If you're lucky enough to get a car that does not have these two issues and lucky enough that the previous owners took good car of the car, then yes, 300,000 miles is possible. And there are definitely some high mile cars like that out there. However, I would say, most are not.

A shop who knows what they are doing and looking for, can do a PPI and tell you whether or not you have worn guides (probably with 85% certainty). An oil analysis can tell you whether you have worn bearings.

Just my 2 cents

Thanks for your insight. I passed on the car anyways but it's useful information nonetheless.
