    Have any of you with Sonomas ever replaced the oil cooler lines yourself?

    I believe the factory lines are/were known to be terrible. I don't think there was ever a recall on them, but they're known to leak. I've been eye-balling them on Ebay, but am debating on doing the work considering re/re-ing looks like it involves a lot of tight space work.

    The remote oil filter to oil cooler lines on my '93 Jimmy [4.3L] started leaking. My Carquest supplier had them in overnight, Doreman makes them. He had the set in stock from the block to the remote filter but was out of the oter side. I had to massage them some until the air box fit. Lucky we saw that it was leaking, my wife came home and backed into a parking spot and wondered what the fresh oil trail was about...
