Oil leak on a 5.3 liter

A Real Stand Up Dealership

Oil leak on a 5.3 liter

Postby 2003Z71 [OP] » Jul 21 2012, 5:55pm

Well I just got my Silverado back from the dealership after them having the truck for 12 days. I’ll try to keep this shorter than War & Peace. Original problem was an oil leak off the back of the engine/transmission bellhousing area. It had gotten so severe that it was leaking a few large puddles (orange size) overnight. I was going to fix it myself, but time wasn’t something I had an abundance of, and I wasn’t sure of where the oil was coming from. Suspected the rear main seal, but had a problem with that because it wasn’t wet up inside the large chrome inspection cover on the bellhousing. So up to the dealer we go, and after 3 days they call me and say it’s your oil pan and valley pan under the intake manifold. Well I was going to decline the repair on the valley pan and do that myself, but I thought it’s up there, apart, so just fix it all. I don’t want any more leaks! Two days later had my brother take me up to get the truck, (dealer is 54 miles one way.) Looked underneath looked clean and dry, then I drove it back home. Less than 45 minutes of sitting in my driveway and I had another puddle! AAURRGGH! It’s leaking worse!! Now I’m thinking THIS IS WHY I DO ALL OF MY OWN WORK! Called the dealer next morning and asked to talk to the owner. Told him the situation and he set up a meeting for the following morning. He thanked me for the phone call and handling it the way I did and not by kicking in his front door and fire-bombing his lobby. Met with the owner and service manager and they gave me 3 options. They would refund the entire $950 and I could take it somewhere else, he would refund half and I could fix it myself in a bay at his dealership. (That one blew me away!) or let them pull it onto a rack and take a look again. I decided since the owner is now involved I’d let them look again. Turns out the first tech screwed up the installation of the oil pan gasket, and he replaced the entire valley pan because he was told the gasket wasn’t available separately. They kept the truck for another 6 days, AND I had to drive a Subaru loaner! In the end I got $230 bucks back for the valley pan and $150 bucks for my time and trouble. I’ve posted before and sfter photos and as you can see by the after photos the underside of the engine/truck is as clean as new. I have driven it for three days now; I’m still keeping an eye on it.
Thought I'd post this, maybe it will help some of the other guys with where oil leaks are on thier 5.3's.

It is really great to hear when a dealer takes responsibility for their mistakes and the fixes it correctly. We hear so often about when a dealer screws up, but not when they do something good. Happy that it all worked out for you.

Yea, part of reason for my post was to give credit to the dealership, which I see I left the name out after I revised my post. It's Davidson-Gebhardt Chevrolet in Loveland. I highly recommend them to anyone in the Denver metro area. They really stepped up and took care of everything under warranty.

That's exactly why I hate going to the dealer or letting anyone else work on my vehicles. I had my rear pinion seal replaced under warranty, it leaked the same day. Took it back and they replaced it again, leaked in a week. Had the dealer order me a seal and I replaced it at home, been leak free for 2 years now. Not sure what they did but I don't think they know how to install a seal without damagine it. The one I took out was pinched.

Glad you got that oil issue taken care of. Keep an eye on it though, hopefully they did it right this time.

Well maybe I'm old school or maybe I've built too many Oldsmobile V-8's, :D but the valley pan is also the pushrod cover. On the 5.3's, it's the cover with the knock sensors in it.

I just recently noticed an oil leak on my 2013 1500. After looking at it, I figured it was the oil filter, which I found to be less than hand tight (after 5,000 miles with this filter). I brought it in to the dealer and they told me they had gotten a bad batch of filters, and have had them fall off trucks more than once.

Hopefully this helps someone, just reinforces to check simple things first. I will post again if it does not fix the problem.

Agreed!
