Has anyone had any success in just cleaning thier opti? I had opti issues, coolant leak right into the damn plug of it. I took it apart and cleaned it inside n out with contact cleaner, hoping it will work tomorrow. ANyone else try this before?

 

Clean a fresh wet opti you might bo ok. Cleaning one that has corrosion and been wet a long time may be something different. Just because a waterpump leaks dont means the opti gets wet on the inside. Just a thought. If it is running ok, why fix it if it aint broke.

 

well cause it missfired pretty bad, backfired, and then one day just didnt crank. I took it apart to find some coolant or something was sitting in the bottom of it, inside and out now its clean. I dont kno how it affected the electrical parts of it tho. Its worth a shot i guess, if anything it may save me $200 on a new opti

 

Always worth a shot for cleaning. You might consider sealing it with some RTV when you put it together. What year is your car?

 

What is an opti and what does it do? What can it do for HP?

 

did you say your car won't start only crank? if so it might be the optical sensor part and in that case you need a new opti. If you get it back together and it doesn't run let me know. I'll tell you how to diagnose it.

...although I have heard of people cleaning there opti's and it working. I have tried it on mine along w/ checking the wires and plugs and all kinds of stuff w/ no luck! Finally when the optical sensor had it and the car won't start is when I bought a new one. And now my hp is back.
...now I just got to get some headers and custom y-pipe to take care of that exhaust leak.

oh and to z28ssslp the opti. is our car's version of the distributor. It's called a optispark because of the optical sensor that reads the cam positioning. It sits under the water pump of are cars on the front of the engine.

I believe my opti is what I'm fighting with right now. I drove to a friends house and noticed some coolant leaking. I popped the hood to find a loose upper hose almost slide off and leaking. The car hasn't started back up since then. That was Wednesday. We now have a fan on the motor to help dry some but I'm not sure what else to do. Keep feeding info.

 

never heard of cleaning one but i guess cleaning it (free) would be a first option rather than replacing it ($$$$$)
