Ok here is the story my 95 Rivera would shut down so I started looking around and found I had a fuel pump issue and the tabs were bad and I had oil leaking from the intake so I decided to repair the intake myself then get the gas tank taken care of so I replaced the gasket and changed the oil in the supercharger. After I put it back together I sent It out to Have a new fuel tank and pump installed. After they started it up coolant was rapidly filling the oil pan. My assumption is that I missed something I checked vacuum lines to make sure I did not hook something up wrong and it was good. So I pulled the supercharger off and did find 1 of the orings distorted. I think that was the cause but is there anything else I should check? I did drop the pan and clean it out and plan to run it with a qt of ATF until it warms up to clean it out there was a lot of residue in the pan but no metal in the filter. The mechanic that changed the tank said I should have used sealant on the bolts that hold the intake in place but it does not look like they could cause this.

why would you run ATF in the engine? to clean it out? I never heard of that?maybe I have but Didnt think it a good idea at the time..I still dont.ATF has friction additives in it.engines dont like/want friction.

The 2 sugestions I had was to run either 25% to 50% ATF or diesel until the engine warmed up and I had spare ATF so I figured I would use it

The O-ring was most likely the problem. Just drain/change the oil like normal after. If you had a LOT of coolant in the oil you may need to change the oil more than once.

Ok the oring fixed the coolant in the oil and after changing the oil the second time that issue is taken care of. Now I have an electrical issue the fan is always running and the tach is not working I can’t find anything disconnected or blown fuses any Ideas?

Look for a ground you missed or broke.

ATF is fine. Gunk engine cleaner is basically kerosene. I personally flush my engines using a kerosene/oil mix.

Well here is the update the coolant in the oil was from the yellow oring under the supercharger there was a coolant leak coming from the coolant pipe on out of the intake new oring corrected that. I used the atf and ran it until warm then changed the oil nice and clean. The electrical short was from a wire in the driver’s door it was blowing a fuse.it was for the light I taped it up problem solved at some time I may go back and rerun the light. I am taking it out for a 100 mile round trip in the morning I put a can of seafoam in the fuel and I am going to change the oil when I get back.
