does anyone have a good way of cleaning the engine bay of a 92 vette without distroying the opti. Thanks

I use simple green, a brush and towels. I've sprayed the bay in the past, the opti isn't that delicate, just keep in mind it's there.

I cleaned mine on Friday. I used a hose, simple green and a leaf blower.

Have an L98 so washing is not a big deal.

I use a small electric powerwasher, simple green and a leaf blower.

Do not use a power washer near the front of the engine. Simple Green, brushes, rags and a hose are all you need.

what if you were to wrap the opti up with plastic wrap or tape or something while you clean the engine? would that work?

PLRX

That would force water IN the opti. Then, you are done

You can soak a rag in kerosene and cram it around the opti and it will keep the majority of water away from it. It's still best to not spray it directly though.

I have used Armor-all Foaming tire cleaner as a quickie clean. It makes a world of difference especially if the bay hasn't been cleaned in a while. Spray it on and leave it on, don't rinse it off. If the area is slightly warm it helps.

Take you time and do it slowly part by part.Spend time in your man-cave and enjoy.I wax everything in the wheel well ,shocks ,upper n lower control arms etc for ez clean-up later on.

This is my Simple Green story. I was doing some work on my son's Volvo and there is quite a bit of oil around. I sprayed Simple Green over the engine, waited a few minutes and hosed it off. I found myself looking at bare wires where the wiring harness used to be. I'm not saying that the harness wasn't old and that it shouldn't have been replaced at some time, but that "cleaning" meant that the car was off the road until the repair could be done. I wonder how long it would have lasted without the Simple Green.

Maybe simple green just took off the grease insulation.

^^Didn't Bogus discover that the simple green had eaten some of his Bell housing where it was allowed to pool and sit for extended period of times?

Yup Here it is......

Thanks guys for the info. I just bought the car and it looks like the engine has never been touched. Thanks again

I have had Simple Green eat away some types of rubber gaskets

Which years do you have to worry about the opti?

PLRX

92-96

I think it was 95 and 96 had a vented opti. Am I correct?

I had a 92 (worst opti) but, that sucker had 195,000 miles and the day before it died I was hauling at 140 MPH.

Brake Cean is a good product to use on lower greasey areas also. I dont know what it would do around the infamous opti-spark though

Just be careful using it in the close confines of an engine bay; you could quickly find yourself reliving your last Grateful Dead concert.

I just shove a rag down in there and try to be careful.
