Gen2-LT4

Ok im finishing up my LT-4 long block and I have an MSD cap and rotor kit. The 2 shaft o-rings disintegrated but it looks like the kit includes them, thank goodness.

The problem is the optical rotor and housing is hosed in oil. What can I use to safely clean it? Ive searched the Google's but can't get any answers? WTF?

Here is what it looks like:

Search the forum for “optidoctor” or message “berrington1” on ebay. He just rebuilt my optispark and from what I can tell, knows everything about them. He offered me advice via ebay messaging even though I had not bought his rebuild service yet. He is knowledgeable and seems willing to answer questions. To me it was worth the $300.

It works fine and only had 56k miles on it. I just want to clean it up before putting this $175 MSD cap on it. Lol

I get that, I’m saying he may tell you how to do it without screwing it up. That disc and sensor are sensitive.

Gotcha, I'll definitely reach out. Thanks for the info!

FWIW when I clean mine I lay the disc on a paper plate and wipe clean with a Kleenex & alcohol. I use electrical contact cleaner sprayed on QTips and or Kleenex for the optical sensor. With the Kleenex I fold it over a few times, spray some cleaner on it and pull it through the optical sensor slot. I completely disassemble the Opti except shaft & bearing. Easy work just sitting at table. Use a large roll of tape as a stand to sit Opti on

Ok so you don't use compressed air or spray cleaner directly on anything?

BALLSS

Compressed air is fine. I don't spray anything directly on it. Just the Q tip and kleenex

You can also get some electrical terminal cleaner that may work well. It's from the CRC (Brak-leen) company. I've used it before, it's a very fast drying cleaner that's very similar to Brak-leen itself and through the years I've actually used Brak-leen to clean electrical parts but never an Opti.
