Blue smoke coming out of left exhaust

Hello,

Blue smoke from a tailpipe usually indicates that that bank of cylinders is burning oil. The reasons for this could be a few things. You could have worn valve guides, worn oil rings, cracked cylinder head or engine block, but with the mileage on your vehicle, I would lean towards worn piston rings. A good way to test for this is to do a standard compression test on that bank of cylinders. Here is a link for you to go to explaining how to do this:

Next, you want to take the cylinders with the lower compression and pour a teaspoon or so of engine oil into the spark plug hole and then rerun your compression test. If the compression rises from the first readings of the earlier compression test, then it is worn rings that are causing the problem.

A good place to find a good used engine, especially a Chevy 350 C.I.D. engine would be to go to eBay's used auto parts warehouse called LKQ which you can easily find on the internet. They should have any condition engine available for purchase. The main concern is staying away from an engine with higher mileage, as is the case with every vehicle that is purchased, so nothing here really changes. Please go through this guide and get back to us with what you are able to find out.

Thanks,
