Engine reseal or replacement?

Hey everyone,

I found out today that the oil leak I've been chasing recently is actually several small oil leaks at pretty much every gasket seal. I was quoted anywhere between $1500-2000 to do a full reseal on my L67. I rarely if ever, see any Rivieras with the L67 in stock at my local pull a part yard, so I'm curious about a couple things. I'm fond of the L67 and it does hold some sentimental value as my grandparents owned a similar L67 Riv. So getting rid of it isn't really an option.

Is there anything else from GM that would bolt in relatively easy? I'm ok with paying 2k if I'm getting a good engine. Is the stock supercharger compatible with other GM engines? If not, I have 117k miles on the current engine, if I choose to do a reseal, should I also do a complete rebuild while I'm at it? Also, is 1500-2000 about average for a full reseal, or am I being had?

At some point I would like to do a RWD conversion, so if I do have to swap engines, at least I can have that in the back of my mind.

Thanks everyone

The most common oil leak on the L67 are the valve covers. I would just re do the 2 covers and that will probably take care of 80% of your leak. Maybe the oil pan if that looks like a leak source as well. That won't get anywhere near halfway to 1500.00.

Replace the engine? Why? For oil leaks? NOTHING will bolt in easily, and that will likely cost you much more. The L67 has been known to go over 300,000 miles. I currently have nearly 186,000 on mine with no sign of it getting tired.

RWD conversion, that's gonna cost you bigtime. Not really a realistic idea IMHO.

That's all very helpful information Larry, I appreciate it. Think I'll start calling other shops for estimates on the valve cover swap

Much better idea.  Oil leaks are pretty common.  Mine leaks, but I just monitor the oil level and replace.  Here in the North east, with our winters, road salt takes it's toll on the underside of our cars.  I think having my sub frame coated with oil helps retard the corrosion, so I leave it.
