Default 93 PA Rod knock.

Well the other day I was in a rush to get somewhere, so I started the car on a 20 degree morning and took off. Got about 1/2 a mile from my house and I could hear a consistant knock right around 4,000+ rpms. So I drove it to my shop a few miles away and picked up my other car.

Now I am planning on just dropping the pain and throwing new rod bearings in. The car was free for me since it was from a customer who didn't want to repair a blown AC clutch. So I don't plan on throwing a ton of money at this thing. Since I got it, it has always had ,what I thought, low oil pressure when it has been ran for 30+ minutes. At idle the oil pressure light would flicker on and off.

Basically I'm asking if anyone thinks it would be worth slapping bearing into this thing and calling it a day since It has about 2 drivin miles with a knock, or if I should just cut my losses and sell it. I'm a very capable mechanic of doing pretty much anything so I'm very open minded to suggestions. I just don't want to pour money into this thing.

Thanks

If your looking to keep it as a daily driver and can do the work your self, then ya, it'* worth swapping them. If you looking to fix it and sell it, the value of the car is so low it'* hardly worth the effort. So what you do is really up to what your future plans or the car is.

Yea I guess you're right. It is my first first V6 though and it'* */Ced which makes it to be pretty fun. Plus I added a nice dual exhaust setup on it so it'* hard to let go.

So you think it would be worth just slapping bearings in it? I really don't want to dump complete rebuild type of money into it. It'* not really a daily driver. Just something different to get me out of my DSM once in awhile.

It depends on what a set of rod bearings will cost for that engine. I personally enjoy working on engines, so I would do it. I'd pull the engine and have it on the stand, much easier that way.

I can get rod bearing for $25 for the set. And I like you also love building engines. My last was a full rebuild on my DSM engine which I did while I was waiting for my license to be restored. But since I am planning on buying another house soon and I just got married, funds are a bit limited so I'm trying to keep the cost down.

Thanks for the help. You and a few select others on here seem to really know your stuff and enjoy what you do from looking at your multiple other threads offering How-tos and advice. So I'm glad you responded.

$25 isn't all that bad. Throw a oil pan gasket on that and you should have all you need. Should be able to get that done in a day. A good running engine makes selling it much easier.

Are you sure its rod bearing noise and not main bearing?

either way www.rockauto.com has them both. and you can apply our discount code to help with the savings.

Bearings, pan gasket, oil + filter, and a little rtv black or orange silicone in the gaskets main corners and away you go! I prefer a hair in the corners as a added safety.
Hope this helps

Well I spun a rod bearing. It blows. The crank has a small gouge in it. I'm just gonna slap bearings in it and sell it. Hopefully I can get a decent chunk out of it and go buy a GSX. Any idea where I can just get one rod bearing?

Dont waste your time! It won't last at all! It will just gernade within a few minutes to a few hours. Plus it will and can end up to be more of a head ache. If you sell it just to push it off, it would only be fair to tell the buyer what happened and that you didn't do the job right. Your risking the possibility of having a buyer turn around and sue you for either the amount of the car and or the repair bill. Worse yet if it locks up and some lady can't steer it without power steering and crashes and has children, then there'* a bigger issue.
