Default Engine Cleaning

I have a 92, which puts me right in the middle of that Optispark debacle.

I NEED to clean my engine, but obviously don't want to break my car. What's the solution here?

Hello Bradly, I have not talked to you yet, so welcome to the forum :seeya


Next time, post this under the- "Car Care" section.


The most effictive way that you can clean your engine is hand cleaning it. Get ready to designate a day to it. You obviously cant spray anything or else it will get on your optispark.

Take 2 buckets- 1 mixed w/ Simple green and water, the other just water.

Clean small sections at a time. Simple rag will do. Clean with water, then simple green, then rinse with water. Eventually you will have it all done.

Although heat is the number 1 killer of your hoses, you can still prevent the eventual rot of your hoses by applying a product such as a rubber protector (not armor all), but something like 303 Aerospace Protectant or similar (a low gloss, no oil one). This will also keep them cleaner longer.

Hope this helps,
Andy

Hay, I'm a new comer to ths C4 corvette and I just did what you said not too. I cleaned the engine with a cleaner and hosed it off. I have started it and it seems okay. Will I have a problem down the road? Also, were is this "opti-spark"?

You don't have an Opti Spark (a crank position indicator that replaces the older distributor) so no need concern. We have a distributor on our L98s.

I use a fine brush and rags with a little carb cleaner to clean my engine. I use tire dressing on the hoses for a nice effect that lasts and Al polish on the intake and accessories & brackets. A stiff brass brush works well to clean up those Al parts too. These are tips I got from two books on detailing; always looking for better ways to keep her looking fine.

Well, based on what I have been hearing, I am!! I guess these setup has been one big pain in the A__! Now I know when I ever sell my 91, to stay away from 92 - 96..

Well, I have not had this 91 too long. I know this was the last year of the L98 and thats why I got it. Going forward, in a few years I may want to move up and gave the 1997 thought. Glad I went with the 91 this time! :D
