my 90 ZR-1 is leaking oil at the oil lines between the block and the oil cooler. What are my best options to keep this Bloomington Gold car original and repair this issue?

thanks!

The cooler lines on ebay that are under $200 new shipped.

Corvette Central does have them but they are not NCRS approved. May be my only choice.

thanks!

They are factory replacements and you will lose what 1 point out of 4,500?

You could always pay $300-$400 for an original set.

The service replacement battery is going make you lost 10 points just to put it in perspective.

Don't go too crazy, you get extra points for driving there, fire extinguisher, ncrs sticker etc.

I know I am entirely to **** about this but my car scored 4472 in April and I am going to try and raise that next time.

My 91 zr1's were just starting to leak when i sold it. I was thinking i would take them off and try to get them repaired. A local radiator and hydraulics repair shop said they could do this and they said they would have been able to keep them as near stock looking as possible.

This was a common problem on these cars and even when they were brand new. Some of the replacement lines from GM neck down from what were originally installed on the car from the factory.

Can you use the later '93+ ones? They have silver fittings instead of black. That's what the GM replacements were (at least recently when I bought mine).

Do they actually look for the different ones based on year? Or could you paint the later ones black and get away with that?

I have SS braided lines on my 1990. When it was NCRS judged I only lost a few points. The oil cooler lines are lumped into a few other parts which helps dilute the point impact.

I have an OEM set from a 1990 that doesn't leak. I might be willing to part with them for enough $$. PM me if you are serious.

thanks everyone! I ordered a set from Corvette Central Saturday morning.
